$scope not updating when I go between pages - angularjs

I am working on an application that goes from template A to template B back to template A. On template A the user click on a button to get to template B. On template B the user add in an amount then hits submit. The program then goes back to template A and displays what was inputted in template B, but the number submitted is not updated in the scope and appears as null. For some reason when I start the application from Template B to Template A the scope is updated.
I am using a factory
.factory('myService', function(){
var budget = {
limit: null
};
function set(data){
budget.limit = data;
}
function get(){
return budget.limit;
}
return{
set: set,
get: get,
print: console.log(budget.limit)
}
})
Here is my code for Template A called BudgetCalc
<ion-view view-title="BudgetCalc">
<ion-content class="padding">
<button>Start Budgeting</button>
<h2>Your Limit is {{limit}}</h2>
</ion-content>
</ion-view>
And Template B named addBuget
<ion-view view-title="Add a Budget">
<ion-content>
<label class="item item-input">
<span class="input-label">Set Spending Limit</span>
<input type="number"ng-model="limit">
</label>
<button ui-sref="tab.budget" ng-click="setLimit(limit)">Submit</button>
<br><h2>Your Limit is: {{limit}}</h2>
</ion-content>
</ion-view>
Here is are my Controllers for the two templates
.controller('BudgetCtrl', function($scope, myService) {
$scope.limit = myService.get();
console.log("This is your limit " + $scope.limit);
})
.controller('SetLimitCtrl', function($scope, myService){
$scope.setLimit = function(limit){
if (limit != null) {
myService.set(limit);
console.log(myService.print);
}
}
})

You can share data between controllers using localstorage
.controller('SetLimitCtrl', function($scope, $localstorage){
$scope.setLimit = function(limit){
if (limit != null) {
$localstorage.set("limit",limit);
console.log($localstorage.get("limit"));
}
}
})
.controller('BudgetCtrl', function($scope, $localstorage) {
$scope.limit = $localstorage.get("limit");
console.log("This is your limit " + $scope.limit);
//// Dont forgot to clear limit when you complete the further process
})
Factory Localsoarage:
.factory('$localstorage', ['$window', function ($window) {
return {
set: function (key, value) {
$window.localStorage[key] = value;
},
get: function (key, defaultValue) {
return $window.localStorage[key] || defaultValue;
},
setObject: function (key, value) {
$window.localStorage[key] = JSON.stringify(value);
},
getObject: function (key, nulled) {
nulled = '[]';
try {
return JSON.parse($window.localStorage[key] || '[]');
} catch (e) {
}
},
delete: function (key) {
$window.localStorage.removeItem(key);
},
};
}])

How To Update Page After Calling $http.put service in Directive Using AngularJS/Web API/Angular-ui-router

We are new to AngularJS but are working on an AngularJS/Web API application that updates a data model from an AngularJS Bootstrap popover/directive.
We've successfully updated the database from the directive/popover, however are having trouble figuring out how to refresh the data on the page with the updated data without reloading the page.
Main Page CSHTML:
<div ng-app="FFPA" ng-controller="myCtrl">
<div svg-floorplan="dataset"></div>
</div>
Popover HTML:
<div>
<div>
ID: {{ person.Id }}<br />
Name: {{ person.fullName }}<br />
Current Cube/Office: {{ person.seatId }}
<br />
Dept: {{ person.deptId }}
<br />
Job Desc: {{ person.jobDesc}}
<br />
Phone:{{ person.phone}}
<br />
<!--<input type="button" value="Click Me" ng-click="changeName()">-->
</div>
<div class="hiddenDiv" ng-hide="toggle">
<div class="form-group">
<label for="floor">Floor</label>
<input id="floor" ng-model="person.floor" type="text" ng-trim="true" class="form-control" />
</div>
<div class="form-group">
<label for="section">Section</label>
<input id="section" ng-model="person.section" ng-trim="true" type="text" class="form-control" />
</div>
<div class="form-group">
<label for="offCubeNum">offCubeNum</label>
<input id="offCubeNum" ng-model="person.offCubeNum" ng-trim="true" type="text" class="form-control" />
</div>
<div class="form-group">
<label for="cbCube">Cubicle?</label>
<input id="cbCube" ng-model="person.cbCube" type="checkbox" size="1" class="checkbox" />
</div>
</div>
<div ng-hide="buttonToggle">
<input type="button" value="Move" class="btn btn-success" ng-click="moveEmp()">
<input type="button" value="Term" class="btn btn-danger" ng-click="changeName()">
</div>
<div ng-hide="submitToggle">
<input type="button" value="Submit" class="btn btn-success" ng-click="submitMove()">
<input type="button" value="Cancel" class="btn btn-warning" ng-click="cancel()">
</div>
</div>
The main page initially gets data from a service in the angular controller:
var app = angular.module('FFPA', ['ngAnimate', 'ngSanitize', 'ui.bootstrap', 'ui.router']);
app.controller('myCtrl', function ($scope, dataService) {
$scope.test = 'test';
dataService.getData().then(function (data) {
//The reduce() method reduces the array to a single value.
$scope.dataset = data.reduce(function (obj, item) {
obj[item.seatId.trim()] = item;
item.fullName = item.fName + ' ' + item.lName;
item.deptId = item.deptId;
item.jobDesc = item.jobDesc;
item.phone = item.phone;
return obj;
}, {});
});
});
Get Data Service:
angular.module('FFPA').service('dataService', function ($http) {
this.getData = function () {
//web api call
return $http.get("api/Controller/GetData).then(
function (response) {
return response.data;
}, function () {
return { err: "could not get data" };
}
);
}
});
The Update Service is called from the Popover Directive.
Update Service:
angular.module('FFPA').service('updateService', function ($http) {
this.putData = function (oc) {
//web api call
return $http.put("api/Controller/PutUpdateData", oc).then(
function (response) {
return response.data;
}, function () {
return { err: "could not update data" };
}
);
}
});
Here is a snippet from our Popover directive where the update occurs and where we thought we could refresh the scope, and the data for the page:
updateService.putData(data).then(function (response) {
if (response == false)
alert("Move Failed!");
else {
alert("Move Succeeded.");
//$window.location.reload() causes a page reload..not desirable
//$window.location.reload();
$state.reload();
}
});
We tried a $state.reload(); in the popover directive just after updateService.putData(data), however this caused -> Error: Cannot transition to abstract state '[object Object]' error.
Here is the full Popover Directive:
angular.module('FFPA').directive('svgFloorplanPopover', ['$compile', 'updateService', 'vacancyService', 'addService', 'terminateService', '$window', '$state', function ($compile, updateService, vacancyService, addService, terminateService, $window, $state) {

UPDATED: 8-MAY-2017
Originally there is one additional data service and a directive that we left out of this post since it may be considered not essential information, however recently added since it may be needed.
SVG Load Directive:
angular.module('FFPA').directive('svgFloorplan', ['$compile', function ($compile) {
return {
restrict: 'A', //restrict attributes
templateUrl: './SVG/HQ3RD-FLOOR3v10.svg',
scope: {
'dataset': '=svgFloorplan'
},
link: {
pre: function (scope, element, attrs) {
//filter groups based on a cube/office id
var groups = element[0].querySelectorAll("g[id^='f3']");
//groups.style("pointer-events", "all");
scope.changeName = function (groupId) {
if (scope.dataset[groupId] && scope.dataset[groupId].lastName.indexOf('changed') === -1) {
scope.dataset[groupId].lastName += ' changed';
}
}
groups.forEach(function (group) {
var groupId = group.getAttribute('id');
if (groupId) {
//set vacancy colors on vacant cubes
scope.$watch("dataset", function () {
if (scope.dataset) {
if (typeof scope.dataset[groupId] !== "undefined") {
//vacant cubes and offices hover
if (scope.dataset[groupId].vacant == true) {
//seat type id 1 = cube
if (scope.dataset[groupId].seatTypeId == 1){
d3.select(group).select("rect").style("fill", "#99ff33").style("opacity", 0.4)
.style("pointer-events", "all")
.on('mouseover', function () {
d3.select(this).style('opacity', 0.9);
})
.on('mouseout', function () {
d3.select(this).style('opacity', 0.4);
})
}
//vacant office
else {
d3.select(group).select("path").style("stroke", "#ffffff").style("opacity", 1.0);
d3.select(group).select("path").style("fill", "#99ff33").style("opacity", 0.4)
.style("pointer-events", "all")
.on('mouseover', function () {
d3.select(this).style('opacity', 0.9);
})
.on('mouseout', function () {
d3.select(this).style('opacity', 0.4);
})
}
}
else { //Occupied
//seat type id 1 = cube
if (scope.dataset[groupId].seatTypeId == 1) {
d3.select(group).select("rect").style("fill", "#30445d").style("opacity", 0.0)
.style("pointer-events", "all")
.on('mouseover', function () {
d3.select(this).style('opacity', 1.0);
d3.select(group).select('text').style("fill", "#FFFFFF");
})
.on('mouseout', function () {
d3.select(this).style('opacity', 0.0);
d3.select(group).select('text').style("fill", "#000000");
})
//TODO: cubes have rects and on the north side of the building wall, paths.
d3.select(group).select("path").style("fill", "#30445d").style("opacity", 0.0)
.style("pointer-events", "all")
.on('mouseover', function () {
d3.select(this).style('opacity', 1.0);
d3.select(group).select('text').style("fill", "#FFFFFF");
})
.on('mouseout', function () {
d3.select(this).style('opacity', 0.0);
d3.select(group).select('text').style("fill", "#000000");
})
}
//occupied office
else {
//d3.select(group).select("path").style("stroke", "#ffffff").style("opacity", 0.8);

d3.select(group).selectAll('text').style("fill", "#000000");
})
}
}//end occupied else
}
}
});
//UPDATE 8-MAY-2017->Implementation Question
scope.onDataUpdateInController = function (person, moreData) { };
var datasetBinding = "dataset['" + groupId + "']";
group.setAttribute('svg-floorplan-popover', datasetBinding);
//UPDATE 8-MAY-2017
//on-data-update corresponds to onDataUpdate item on svgFloorplanPopover's scope.
group.setAttribute('on-data-update', onDataUpdateInController);
$compile(group)(scope);
}
});
}
}
}
}]);
Vacancy Service (check before update):
angular.module('FFPA').service('vacancyService', function ($http) {
...
}
The main question is:
How can we have our application refresh our page with the updated data without reloading the page?
We used to be able to do this in UpdatePanels in ASP.Net webforms back in the day. I think they were partial postbacks/AJAX calls..

Even though the bounty was automatically awarded, we still don't have an answer to this question. Without any implementation context the answers given are not useful.
Can anyone expand on the answers given to give us an idea on how this problem can be solved?
Thanks
Just add your data on $scope object and use it in your view, whenever you update or modify the data just
eg: consider you have a function to get the data where you are making rest call to your db
$scope.getdata=function(){
$http.get(url).success(function(data)
{ $scope.data=data;
});
Whenever you modify your data just call this function in your case on click of close of directive/popup
To refresh your view (not bind the received data) use the answers for the following questions:
Using ngRoute Module
How to reload or re-render the entire page using AngularJS
Using ui-router Module
Reloading current state - refresh data
With that I would recommend you to assign the received data to your bounded $scope property.
I'll add a full example after you'll provide an updated plnkr :)
Please try the following steps:
1. Create a method in svgFloorplanPopover directive and call it by passing in the data
In your svgFloorplanPopover directive, add onDataUpdate item in the scope
declaration:
...
scope: {
'person': '=svgFloorplanPopover',
onDataUpdate: '&'
}
...
and where you are trying to reload state, instead of reloading the state or page, call the below code. This is to create an event system which is fired from within the directive to let the controller or parent directive know that data has changed and view can now be updated.
$scope.onDataUpdate({person: $scope.person, moreData: $scope.moreData});
2. Create a method in svgFloorplan to accept the passed data
Since you are using nested directive approach, you'll need to use the below code in svgFloorplan directive.
group.setAttribute('svg-floorplan-popover', datasetBinding);
group.setAttribute('on-data-update', onDataUpdateInController);
on-data-update corresponds to onDataUpdate item on svgFloorplanPopover's scope.
Declare onDataUpdateInController method on the scope of svgFloorplan directive.
scope.onDataUpdateInController = function(person, moreData) {};
The object properties that you pass from within the directive are laid out flat to the number of parameters.
If you need to pass this data further up to your controller where svgFloorplan is declared. Repeat the above two steps for svgFloorplan directive.
I hope this approach is clear. It is no different than what is explained in Angular Directives, section Creating a Directive that Wraps Other Elements and code where a close button is added. Here is the direct link to the code in plunkr.
Just a question: Are you going to use these directives separately from each other? If no, you may try to create one directive instead of making them two. This will reduce complexity.

Pass object back from ionic model service

I have created a factory for a modal that pulls in an array(list) and I have a ng-click where I get the index and then get the object I want to pass the object back to my controller so I can then use it.
I not sure how I will pass the object back to the controller.
This is the function in my service that fires the open() for the modal and I am passing it the model that i receive from a rest call.
function CopyModalService($ionicModal, $rootScope) {
var $scope = $rootScope.$new(),
myModalInstanceOptions = {
scope: $scope,
animation: 'slide-in-up'
};
return {
open: open
};
function open(model) {
$ionicModal.fromTemplateUrl('templates/copy-modal.html',
myModalInstanceOptions)
.then(function (modalInstance) {
$scope.model = model;
$scope.addCopyCertificate = function(index){
console.log('click', $scope.model[index]);
};
$scope.close = function () {
closeAndRemove(modalInstance);
};
return modalInstance.show(model);
});
}
This is the html in the modal so you can get the picture
<ul class="list">
<li class="item row" ng-repeat="item in model">
<span class="col col-67">{{item.installerReference}}</span>
<span class="col">
<button class="button button-calm button-calm-search ion-ios-arrow-down"
ng-click="addCopyCertificate($index)"></button>
</span>
</li>
</ul>
When I click the button in the html addCopyCertificate() it all appears fine but how do I pass that back to the controller.
In my controller I am using it like this: (which is working)
if (res.length) {
CopyModalService.open(res);
}else{
Alert.showAlert('No matching certificates');
....
}
what about $rootScope.$broadcast? something like:
function CopyModalService($ionicModal, $rootScope) {
var $scope = $rootScope.$new(),
myModalInstanceOptions = {
scope: $scope,
animation: 'slide-in-up'
};
return {
open: open
};
function open(model) {
$ionicModal.fromTemplateUrl('templates/copy-modal.html',
myModalInstanceOptions)
.then(function (modalInstance) {
$scope.model = model;
$scope.addCopyCertificate = function(index){
console.log('click', $scope.model[index]);
$rootScope.$broadcast('update-controller',$scope.model[index]);
};
$scope.close = function () {
closeAndRemove(modalInstance);
};
return modalInstance.show(model);
});
}
and then when you want to get the value ..attach the listener with $rootScope.$on('') (or better $scope.$on()) ..something like
if (res.length) {
CopyModalService.open(res);
$scope.$on('update-controller',function(event, data){
console.log(data);
});
}else{
Alert.showAlert('No matching certificates');
....
}

AngularJS - ng-if runs digest loop

I am facing problem with infinite loop on loading the view. The data is loaded from an API call using ngResource in the controller. The view seems to be reloaded multiple times before rendering the view correctly. I use ng directives in the template calling scope methods and this seems to get into loop causing the view to be re-rendered.
Here is my Controller
.controller('IndexCtrl', ['$scope', '$stateParams', 'ProfileInfo',
function($scope, $stateParams, ProfileInfo) {
$scope.navTitle = 'Profile Information';
$scope.data = {};
ProfileInfo.query({
id: $stateParams.id
}).$promise.then(function(Profile) {
if (Profile.status == 200) {
$scope.data.Profile = Profile.data[0];
}else{
console.log(Profile.status);
}
}, function(error) {
console.log(error);
});
$scope.showImageBlock = function(object, image) {
if (object.hasOwnProperty('type') && object.type == 'image') {
imageReference = object.value;
var imageUrl;
angular.forEach(image, function(value, key) {
if (value.id == imageReference) {
$scope.data.imageUrl = value.graphic.url;
return;
}
});
}
return object.hasOwnProperty('type') && object.type == 'image';
};
$scope.showText = function(object) {
console.log('text');
return object.hasOwnProperty('type') && object.type == 'text';
};
}
])
And Here is my template
<ion-view cache-view="false">
<ion-nav-title>
{{navTitle}}
</ion-nav-title>
<div class="bar bar-subheader bar-light">
<h2 class="title">{{navSubTitle}}</h2>
</div>
<ion-content has-header="true" padding="true" has-tabs="true" class="has-subheader">
<div ng-repeat="profileInfo in data.Profile">
<div class="list">
<img ng-if="showImageBlock(profileInfo,data.Profile.images)" ng-src="{{ data.imageUrl }}" class="image-list-thumb" />
<div ng-if="showText(profileInfo)">
<a class="item">
{{profileInfo.name}}
<span ng-if="profileInfo.description.length != 0"class="item-note">
{{profileInfo.description}}
</span>
</a>
</div>
</div>
</div>
</ion-content>
Here is the output of console window when tried log the number of times showText function is called.
The actual result from ngResource call has only 9 items in array but it loops more than 9 times and also multiple loops. This happens for a while and stops. Could anyone please point me in the right direction in fixing it.
Thank you
Finally I ended up creating a custom directive which does the function of ng-if without the watchers which triggers the digest loop. It's not a pretty solution but it seems to do the job as expected. I copied the code of ng-if and removed the $scope watcher. Here is the custom directive.
angular.module('custom.directives', [])
.directive('customIf', ['$animate',function($animate) {
return {
multiElement: true,
transclude: 'element',
priority: 600,
terminal: true,
restrict: 'A',
$$tlb: true,
link: function($scope, $element, $attr, ctrl, $transclude) {
var block, childScope, previousElements;
value = $scope.$eval($attr.customIf);
if (value) {
if (!childScope) {
$transclude(function(clone, newScope) {
childScope = newScope;
clone[clone.length++] = document.createComment(' end customIf: ' + $attr.customIf + ' ');
block = {
clone: clone
};
$animate.enter(clone, $element.parent(), $element);
});
}
}
else {
if (previousElements) {
previousElements.remove();
previousElements = null;
}
if (childScope) {
childScope.$destroy();
childScope = null;
}
if (block) {
previousElements = getBlockNodes(block.clone);
$animate.leave(previousElements).then(function() {
previousElements = null;
});
block = null;
}
}
}
};
}]);
This allows us to use the customIf as follows
<div custom-if="showText(profileInfo)">

Passing data from ionic/angular modal using separate template html file

I'm developing a simple Ionic mobile app although the answer likely lies with Angular. The app is really simple, displays a list of employees with an Add button which displays a modal, lets the user enter some details, click Save and it's persists the data to a back-end Firebase store. It has 1 controller and a simple service. Initially I had the template html for the modal inside script tags inside the index.html and it all worked fine. When I decided to structure things out and put the modal template in a separate html file, suddenly the data object assigned to ng-modal via the input boxes no longer passes any data to the event handler to save the data, instead it's always undefined. Everything else works as it should, the modal displays ok, the event handlers are calling the right functions etc. The only change is moving the input template to a separate file. I know it's likely something really simple but can't for the life of me work out why and can't find any info about it anywhere else.
Template HTML file for the modal :
<ion-list>
<h1>Add Employee</h1>
<div class="list list-inset">
<ion-item>
<label class="item item-input">
<input type="text" placeholder="Employee Name" ng-model="data.employeeName">
</label>
<label class="item item-input">
<input type="text" placeholder="Employee Age" ng-model="data.employeeAge">
</label>
</ion-item>
<button class="button button-outline button-block button-balanced"
ng-click="addEmployee(true, data)">
Save & Add Another
</button>
<button class="button button-outline button-block button-positive"
ng-click="addEmployee(false, data)">
Save
</button>
<button class="button button-outline button-block button-assertive"
ng-click="closeAddModal()">
Cancel
</button>
</ion-list>
</ion-modal-view>
addEmployee event - data parameter is now always undefined. Worked fine with embedded template :
$scope.addEmployee = function(retainModal, data) {
var employee = {employeeName:data.employeeName,
employeeAge:data.employeeAge};
employeeService.saveEmployee(employee);
if (! retainModal) {
$scope.closeAddModal();
};
data.employeeName = "";
data.employeeAge = "";
};
Based on this question and other needs I create a service that can be useful.
See this post: Ionic modal service or see in operation: CodePen
(function () {
'use strict';
var serviceId = 'appModalService';
angular.module('app').factory(serviceId, [
'$ionicModal', '$rootScope', '$q', '$injector', '$controller', appModalService
]);
function appModalService($ionicModal, $rootScope, $q, $injector, $controller) {
return {
show: show
}
function show(templateUrl, controller, parameters) {
// Grab the injector and create a new scope
var deferred = $q.defer(),
ctrlInstance,
modalScope = $rootScope.$new(),
thisScopeId = modalScope.$id;
$ionicModal.fromTemplateUrl(templateUrl, {
scope: modalScope,
animation: 'slide-in-up'
}).then(function (modal) {
modalScope.modal = modal;
modalScope.openModal = function () {
modalScope.modal.show();
};
modalScope.closeModal = function (result) {
deferred.resolve(result);
modalScope.modal.hide();
};
modalScope.$on('modal.hidden', function (thisModal) {
if (thisModal.currentScope) {
var modalScopeId = thisModal.currentScope.$id;
if (thisScopeId === modalScopeId) {
deferred.resolve(null);
_cleanup(thisModal.currentScope);
}
}
});
// Invoke the controller
var locals = { '$scope': modalScope, 'parameters': parameters };
var ctrlEval = _evalController(controller);
ctrlInstance = $controller(controller, locals);
if (ctrlEval.isControllerAs) {
ctrlInstance.openModal = modalScope.openModal;
ctrlInstance.closeModal = modalScope.closeModal;
}
modalScope.modal.show();
}, function (err) {
deferred.reject(err);
});
return deferred.promise;
}
function _cleanup(scope) {
scope.$destroy();
if (scope.modal) {
scope.modal.remove();
}
}
function _evalController(ctrlName) {
var result = {
isControllerAs: false,
controllerName: '',
propName: ''
};
var fragments = (ctrlName || '').trim().split(/\s+/);
result.isControllerAs = fragments.length === 3 && (fragments[1] || '').toLowerCase() === 'as';
if (result.isControllerAs) {
result.controllerName = fragments[0];
result.propName = fragments[2];
} else {
result.controllerName = ctrlName;
}
return result;
}
} // end
})();
Usage:
appModalService
.show('<templateUrl>', '<controllerName> or <controllerName as ..>', <parameters obj>)
.then(function(result) {
// result from modal controller: $scope.closeModal(result) or <as name here>.closeModal(result) [Only on template]
}, function(err) {
// error
});
You can use another service to centralize the configuration of all modals:
angular.module('app')
.factory('myModals', ['appModalService', function (appModalService){
var service = {
showLogin: showLogin,
showEditUser: showEditUser
};
function showLogin(userInfo){
// return promise resolved by '$scope.closeModal(data)'
// Use:
// myModals.showLogin(userParameters) // get this inject 'parameters' on 'loginModalCtrl'
// .then(function (result) {
// // result from closeModal parameter
// });
return appModalService.show('templates/modals/login.html', 'loginModalCtrl as vm', userInfo)
// or not 'as controller'
// return appModalService.show('templates/modals/login.html', 'loginModalCtrl', userInfo)
}
function showEditUser(address){
// return appModalService....
}
}]);
You need to attach your models to the scope:
$scope.data.employeeName = "";
$scope.data.employeeAge = "";
...and similar every time you reference them.

How to dismiss an angularjs alert when user changes route/state

I am using this angular js service/directive github pageto display alerts. An issue has been opened relating to the question I am asking but it has not been addressed by the developer.
i want first alert shown when user logs in to disappear when the user clicks logout but the alerts are stacking up on top of each other.
Here is a fiddle although I could not replicate the issue but it shows the structure of my code. fiddle
html:
<body ng-app="app">
<mc-messages></mc-messages>
<button ng-click="login()">Login</button>
<button ng-click="logout()">Logout</button>
</body>
js:
/*jshint strict:false */
'use strict';
var app = angular.module('app', ['MessageCenterModule']);
app.controller(function ($scope, messageCenterService, $location) {
$scope.login = function () {
$location.path('/');
messageCenterService.add('success',
'You are now loggedin!', {
status: messageCenterService.status.next
});
};
$scope.logout = function () {
$location.path('login');
messageCenterService.add('success',
'You are now loggedout!', {
status: messageCenterService.status.next
}
};
});
// Create a new angular module.
var MessageCenterModule = angular.module('MessageCenterModule', []);

Hope this is clear enough for someone to help me. If not let me know and I can try to clarify.
