How can I add enteries on click in angularjs? - angularjs

I am using this Plunker as a reference. I want to create a similar one however, the change is I want to add a button and on click each entry should be added in the list. I have created this Plunker. However, I need to add one by one item on click. How can I achieve that? Somehow, I am doing something wrong in this code.
$scope.addRow = function() {
$scope.source.push($scope.counter);
$scope.counter++;
}
Any help would be appreciated.

In order to do what you want, you need to call $scope.source.pageSize(page); after changing it, and then $scope.source.refresh() to apply this change to the source.
angular.module("app", ["kendo.directives"]).controller("MyCtrl", function ($scope) {
var page =1;
$scope.source = new kendo.data.DataSource({
transport: {
read: {
url: "http://demos.telerik.com/kendo-ui/service/products",
dataType: "jsonp"
}
},
pageSize: page
});
$scope.add= function(){
page++;
$scope.source.pageSize(page);
$scope.source.refresh();
}
});
here's working plnkr

You are just pushing the counter into the array, you should push the text instead.
angular.module("app", []).controller("MyCtrl", function ($scope) {
$scope.source = [];
$scope.addRow = function(text) {
$scope.source.push(text);
}
});
and in your view:
<div ng-app="app" ng-controller="MyCtrl">
<input type="text" ng-model="some_text"/>
<input type="submit" value="Add" ng-click="addRow(some_text)"/>
</div>

Angularjs button ng click not working

I have a button on clicking which a popup is opened, addRow function is called to add a row. This row has a button on clicking which new rows can be added. However when i click on this, no function is called and nothing happens. Please help.
<body ng-app="myApp" ng-controller="myCtrl">
<div id="sample"><!-- onload="init()">-->
<h3>Make your own Flowchart</h3>
<button ng-click = "addSystem()" type="submit" id="btn-save">Add System</button>
Within my controller code starts as follows.
<script type="text/javascript">
var app=angular.module('myApp',[]);
app.controller('myCtrl', function($scope)
{
$scope.sysInfo=[];
later i have addSystem function is as follows:
$scope.addSystem=function()
{
console.log("Inside add system");
var str="<form><table id=\"sysTab\"></table></form>";
console.log("str is "+str);
$(str).dialog({
modal: true,
title:"Add system info",
height:"auto",
width:"auto",
buttons: {
'OK': function () {
//console.log($('#sysName'));
init();
$( this ).dialog( "close" );
},
'Cancel': function () {
$(this).dialog('close');
}
}
});
$scope.addRow();
}
$scope.addRow=function()
{
$scope.index=$scope.index+1;
console.log("index is "+$scope.index);
console.log("Inside add row");
$('#sysTab').append("<tr><td>System Name : </td><td><input rowid=\""+$scope.index+"\"type=\"text\" id=\"sysName"+$scope.index+"\"/></td><td><input type=\"text\" class=\"basic"+$scope.index+"\"/></td><td><input type=\"button\" value=\"+\" ng-click=\"addRow("+$scope.index+")\" title=\"Add new system info\"/></td><td><input type=\"button\" value=\"-\" onclick=\"deleteRow(this)\" title=\"Delete system info\"/><p id=\""+$scope.index+"\" style=\"display:none;\"></p></td></tr>");
console.log("row added");
$(".basic"+$scope.index).spectrum({
color: "#f00",
change: function(color) {
console.log("Inside change");
console.log($('#sysName'+$(this).closest('tr').index()).val());
sysInfo.push({"index":$(this).closest('tr').index(), "name": $('#sysName'+$(this).closest('tr').index()).val(), "color":color.toHexString()});
console.log(sysInfo);
}
});
}
i tried calling as $scope.addRow() but i am getting no response. i tried a lot without any success. Any pointers will be greatly helpful.
The issue of $scope not defined is resolved by explicitly calling out the scope as angular.element(document.getElementByID('master div element here').scope()

Ng-repeat - "Are you sure to delete ?" from a modal

I'm retrieving a list of objects (item) from a Django API.
my_app.factory('list_of_items', function($resource) {
return $resource(
'/api/petdata/') });
Then I display everything in a html page within a ng-repeat:
<div ng-controller="ModalDemoCtrl">
<div ng-repeat="item in items | filter:{display:'1'} | orderBy: 'item_name'">
<div class="box box-widget widget-user">
{{ item.pet_name }}{% endverbatim %}
<button type="button" class="btn btn-box-tool" ng-click="askDelete(item)" href="#"><i class="fa fa-times"></i></button>
</div>
<div>
Everything's fine so far.
Then I want the user to be able to delete one of the item by clicking on the button from the html page.
What means deleting here :
1. Update the API database by changing the property "display:1" to "display:0".
2. Remove the item from the ng-repeat.
I want to make a "Are you sure" modal to confirm the delete process.
This is the askDelete function.
angular.module('djangular-demo').controller('Ctrl_List_Of_Pets', function($scope, $http, $window,$filter,list_of_pets,pet_by_id,$uibModal) {
$scope.items = list_of_items.query()
$scope.askDelete = function (idx,item,size,parentSelector) {
// console.log("PET",$scope.pet_to_be_undisplayed);
var parentElem = parentSelector ?
angular.element($document[0].querySelector('.modal-demo ' + parentSelector)) : undefined;
var modalInstance = $uibModal.open({
animation: true,
ariaLabelledBy: 'LOL',
ariaDescribedBy: 'modal-body',
templateUrl: "myModalContent.html",
controller: function($scope) {
$scope.ok = function() {
modalInstance.close();
};
$scope.cancel = function() {
modalInstance.dismiss('cancel');
};
},
size: size,
appendTo: parentElem,
resolve: {
}
});
modalInstance.result.then(function() {
reallyDelete(item);
});
};
var reallyDelete = function(item) {
$scope.entry = items_by_id.get({ id: item.id }, function() {
// $scope.entry is fetched from server and is an instance of Entry
$scope.entry.display = 0;
$scope.entry.$update({id: $scope.entry.id},function() {
//updated in the backend
});
});
$scope.items = window._.remove($scope.items, function(elem) {
return elem != item;
});
};
});
What works :
Updating the DB works with a PUT request (code hasn't been provided).
What doesn't work :
Removing the item from the ng-repeat never works. Or it throws me an error like here because it doesn't know window._.remove or it doesn't know $scope.items. It depends from what I try. Or the modal close and there is no update of the ng-repeat list, no refresh and every items remain whereas the PUT request to update worked.
I read every article on scope inheritance and I think I didn't make any mistake here but I'm might be wrong. I've been struggling for too long so I post here !
Would you suggest anything to make it work ?
Thank you for your rime.
First:
$scope.askDelete = function (idx,item,size,parentSelector) receives the item index, the item, size, and parent selector... and you are calling ng-click="askDelete(item)"
I assume you are attempting to pass the item, but in askDelete you are receiving as first parameter the index (maybe you should do ng-click="askDelete($index)"?)
Second:
In reallyDelete why are you removing the items array like this:
$scope.items = window._.remove($scope.items, function(elem) {
return elem != item;
});
?
IMHO, it would be a much cleaner code if we just do:
$scope.items.splice(idx, 1) //<- idx would be the idx of the entry in the items

angular ng-repeat to always show even on empty object

Hi I want to post item to server, and with each successful addition, automatically add it to DOM with ng-repeat
<div class="" ng-repeat="book in books" >
<div id="eachBook">{{book.title}}</div>
</div>
to POST the data and also to upload an image file, I use Jquery ajax, and $state.go(".") to reload the current page:
var fd = new FormData();
fd.append("file", bookImage);
$http({
method: 'POST',
url: "/someurl,
data: fd,
headers: {
'Content-Type': undefined
}
}).success(function(Image){
var book_obj = {
bookTitle: bookTitle,
bookImage: Image._id
};
$http.post("url to owner book", book_obj)
.success(function(data){
$scope.bookImage = data.bookImage;
$timeout(function(){
alert("success", "successfully added your book");
$state.transitionTo('book', {}, { reload: true });
},2000);
})
})
The problem is with first addition, the DOM is still empty, and even though I use $state to reload the page, it still not working for the first addition. In the end I need to refresh the page manually by clicking refresh.
after the first addition, it works fine. With each book added, it automatically added to DOM..
Any idea how to automatically start the first one without manually rendering the page? using $timeout to delay the refresh has no effect.
Is it not just a simple post to list on success?
var app = angular.module('myApp', []);
app.controller('bookCtrl', function($scope, $http, $timeout) {
$scope.init = function(){
$scope.title = 'initial book?'
postBook();
};
$scope.books = [];
$scope.post = function() {
postBook();
};
function postBook(){
if (!$scope.title) return;
// timeout to simulate server post
$timeout(function() {
$scope.books.push({title:$scope.title});
$scope.title = null;
}, 1000);
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="bookCtrl" ng-init="init()">
<div class="" ng-repeat="book in books">
<div class="eachBook">{{book.title}}</div>
</div>
<input type="text" ng-model="title" /><button ng-click="post()">save</button>
</div>
EDIT: Not sure why your DOM isn't ready but how about ng-init to accomplish an initial book post?

How to update ng-repeat after updating array

I have a following controller
app.controller('MainController', function($scope, $interval,$mdToast, $document, $mdDialog,$timeout,$mdDialog) {
var stops=[
{
stopName:"testinput1",
noOfStudents:2
},
{
stopName:"testinput2",
noOfStudents:2
},
{
stopName:"testinput3",
noOfStudents:4
}
];
$scope.list=stops;
$scope.addStop=function(name,noOfstudent){
stops.push({
stopName:name,
noODstudent:noOfstudent
})
$scope.list=stops;
}
});
in my view I have following code,
<md-list id="stopList">
<md-list-item class="md-3-line" ng-repeat="item in list" style="background:rgb(233, 233, 233);margin:10px;padding-left: 10px;position: relative;min-height: 60px;">
<div class="md-list-item-text">
<h3>{{item.stopName}}</h3>
<h4>{{item.noOfStudents}}</h4>
</div>
<div ng-show="deleteIcon" ng-click="showConfirm($event);" class='delete_icon'></div>
</md-list-item>
</md-list>
The issue I am facing is when I add a stop, the ng-repeat list does not get updated. I want the view to be updated as I add a stop. I am taking the user input from angular material dialog.
Data will be updated automatically in view after you update it in controller. What problem (may be ) you are facing is typo in addStop function.
You have used two dots when updating list. >> $scope..list=stops;
You don't need to push to stop
Just direct push to $scope.list
When stop assigned in the list it'll assign reference if one is updated another will also
$scope.list=stops;
Like this
$scope.list.push({
stopName: name,
noODstudent: noOfstudent
})
Here is a plnkr:
http://plnkr.co/edit/HlzxQ9sqbMbxDiraT22z?p=preview
Seems to be working for me
var name = 'l'
var noOfStudents = 5
$scope.addStop=function(){
stops.push({
stopName:name,
noOfStudents:noOfStudents
})
$scope.list=stops;
}
i have used static data but there should not be any problem
Try this
$scope.addStop = function (name, noOfstudent) {
stops.push({
stopName: name,
noODstudent: noOfstudent
});
$timeout(function () {
$scope.list = [];
$scope.list = stops;
}, 0);
};

update angularjs model from jquery [duplicate]

I have this simple scenario:
Input element which value is changed by jQuery's val() method.
I am trying to update the angular model with the value that jQuery set. I tried to write a simple directive, but it's not doing what I want.
Here's the directive:
var myApp = angular.module('myApp', []);
myApp.directive('testChange', function() {
return function(scope, element, attrs) {
element.bind('change', function() {
console.log('value changed');
})
}
})
this is the jQuery part:
$(function(){
$('button').click(function(){
$('input').val('xxx');
})
})
and html:
<div ng-app="myApp">
<div ng-controller="MyCtrl">
<input test-change ng-model="foo" />
<span>{{foo}}</span>
</div>
</div>
<button>clickme</button>
Here is the fiddle with my try:
http://jsfiddle.net/U3pVM/743/
Can someone please point me in the right direction?
ngModel listens for "input" event, so to "fix" your code you'd need to trigger that event after setting the value:
$('button').click(function(){
var input = $('input');
input.val('xxx');
input.trigger('input'); // Use for Chrome/Firefox/Edge
input.trigger('change'); // Use for Chrome/Firefox/Edge + IE11
});
For the explanation of this particular behaviour check out this answer that I gave a while ago: "How does AngularJS internally catch events like 'onclick', 'onchange'?"
But unfortunately, this is not the only problem you have. As pointed out with other post comments, your jQuery-centric approach is plain wrong. For more info take a look at this post: How do I “think in AngularJS” if I have a jQuery background?).
Hope this is useful for someone.
I was unable to get the jQuery('#myInputElement').trigger('input') event to be picked up my angular app.
I was however, able to get angular.element(jQuery('#myInputElement')).triggerHandler('input') to be picked up.
The accepted answer which was triggering input event with jQuery didn't work for me. Creating an event and dispatching with native JavaScript did the trick.
$("input")[0].dispatchEvent(new Event("input", { bubbles: true }));
I don't think jQuery is required here.
You can use $watch and ng-click instead
<div ng-app="myApp">
<div ng-controller="MyCtrl">
<input test-change ng-model="foo" />
<span>{{foo}}</span>
<button ng-click=" foo= 'xxx' ">click me</button>
<!-- this changes foo value, you can also call a function from your controller -->
</div>
</div>
In your controller :
$scope.$watch('foo', function(newValue, oldValue) {
console.log(newValue);
console.log(oldValue);
});
You have to use the following code in order to update the scope of the specific input model as follows
$('button').on('click', function(){
var newVal = $(this).data('val');
$('select').val(newVal).change();
var scope = angular.element($("select")).scope();
scope.$apply(function(){
scope.selectValue = newVal;
});
});
I made modifications on only controller initialization by adding listener on action button:
$(document).on('click', '#action-button', function () {
$timeout(function () {
angular.element($('#input')).triggerHandler('input');
});
});
Other solutions did not work in my case.
I know it's a bit late to answer here but maybe I may save some once's day.
I have been dealing with the same problem. A model will not populate once you update the value of input from jQuery. I tried using trigger events but no result.
Here is what I did that may save your day.
Declare a variable within your script tag in HTML.
Like:
<script>
var inputValue="";
// update that variable using your jQuery function with appropriate value, you want...
</script>
Once you did that by using below service of angular.
$window
Now below getData function called from the same controller scope will give you the value you want.
var myApp = angular.module('myApp', []);
app.controller('imageManagerCtrl',['$scope','$window',function($scope,$window) {
$scope.getData = function () {
console.log("Window value " + $window.inputValue);
}}]);
I've written this little plugin for jQuery which will make all calls to .val(value) update the angular element if present:
(function($, ng) {
'use strict';
var $val = $.fn.val; // save original jQuery function
// override jQuery function
$.fn.val = function (value) {
// if getter, just return original
if (!arguments.length) {
return $val.call(this);
}
// get result of original function
var result = $val.call(this, value);
// trigger angular input (this[0] is the DOM object)
ng.element(this[0]).triggerHandler('input');
// return the original result
return result;
}
})(window.jQuery, window.angular);
Just pop this script in after jQuery and angular.js and val(value) updates should now play nice.
Minified version:
!function(n,t){"use strict";var r=n.fn.val;n.fn.val=function(n){if(!arguments.length)return r.call(this);var e=r.call(this,n);return t.element(this[0]).triggerHandler("input"),e}}(window.jQuery,window.angular);
Example:
// the function
(function($, ng) {
'use strict';
var $val = $.fn.val;
$.fn.val = function (value) {
if (!arguments.length) {
return $val.call(this);
}
var result = $val.call(this, value);
ng.element(this[0]).triggerHandler('input');
return result;
}
})(window.jQuery, window.angular);
(function(ng){
ng.module('example', [])
.controller('ExampleController', function($scope) {
$scope.output = "output";
$scope.change = function() {
$scope.output = "" + $scope.input;
}
});
})(window.angular);
(function($){
$(function() {
var button = $('#button');
if (button.length)
console.log('hello, button');
button.click(function() {
var input = $('#input');
var value = parseInt(input.val());
value = isNaN(value) ? 0 : value;
input.val(value + 1);
});
});
})(window.jQuery);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div ng-app="example" ng-controller="ExampleController">
<input type="number" id="input" ng-model="input" ng-change="change()" />
<span>{{output}}</span>
<button id="button">+</button>
</div>
If you are using IE, you have to use: input.trigger("change");
add .change() after setting the value.
example:('id').val.('value').change();
also don't forget to add onchange or ng-change tag in html
I did this to be able to update the value of ngModel from the outside with Vanilla/jQuery:
function getScope(fieldElement) {
var $scope = angular.element(fieldElement).scope();
var nameScope;
var name = fieldElement.getAttribute('name');
if($scope) {
if($scope.form) {
nameScope = $scope.form[name];
} else if($scope[name]) {
nameScope = $scope[name];
}
}
return nameScope;
}
function setScopeValue(fieldElement, newValue) {
var $scope = getScope(fieldElement);
if($scope) {
$scope.$setViewValue(newValue);
$scope.$validate();
$scope.$render();
}
}
setScopeValue(document.getElementById("fieldId"), "new value");
Not what OP asked, but for any soul that might be as well writing an userscript that goes through input fields and fills the required details. Nothing (fully) worked for me, but finally managed to get it done this way:
var el = $('#sp_formfield_fw_ip');
el.val("some value");
angular.element(el).triggerHandler('focus');
angular.element(el).triggerHandler('input');
angular.element(el).triggerHandler('change');
angular.element(el).triggerHandler('blur');
Open developer tools, and inspect input field for added events. There I found all of them (in my case): focus, input, change and blur.
