How to use ng-click value as ng-repeat property? - angularjs

How to get $scope.clickedVal in r.clickedVal?
Button click calls a function, passing in two parameters:
<a ng-click="display('Info', 'Admission_Info'); filters.Admission_Info= '!!'; ">Info</a>
<a ng-click="display('Info', 'SomeOther_Info'); filters.SomeOther_Info= '!!'; ">Other</a>
Function in the controller:
$scope.display = function (col, val) {
$scope.filters = {};
$scope.clickedColumn = col;
$scope.clickedVal = val;
};
Table displays a filtered view with 2 columns.
<tr ng-repeat="r in response | filter:filters as filtered " ng-show="filtered.length">
<td>{{ r.Name }}</td>
<td>{{ r.clickedVal }}</td>
</tr>
{{ r.{{clickedVal}} }} didn't work.
So for example, if the first button is clicked, r.clickedVal should return r.SomeOther_Info.
I've tried creating a filter as well but run into the same issue - m.value is incorrect.
SchoolProgramsApp.filter('myFilter', function () {
return function (input, column, value) {
var out = [];
angular.forEach(input, function (m) {
if (m.value === value) {
out.push(m)
}
})
return out;
}
});

You should use bracket notation to access property of the object by variable name:
{{ r[clickedVal] }}

Prevent users from selecting same value in multiple dropdowns

I am loading a table from an API call , table rows are dynamic and it is based on the returned values from API call. I am displaying sort order and value should be unique and user shouldn't select a previously selected values. I tried to follow as per this (http://jsfiddle.net/jnash21/oqezom4y/) but i am not able to achieve as mine is dynamic.
I tried this (http://embed.plnkr.co/QU4r05n9rQprwyL9Ltxh/) .
editor.controller('EditorController', function($scope) {
$scope.entities = [{name:"pencil",sortOrder:""} ,{name:"notepad",sortOrder:""} ,
{name:"bookshelf",sortOrder:""}
];
$scope.sortOrderValues=[1,2,3];
});
<table>
<tr ng-repeat="x in entities">
<td>{{ x.name }}</td>
<td><select ng-model="x.sortOrder"
ng-options="col for col in sortOrderValues">
</select>
<span ng-show="!x.sortOrder"> * sort order required</span>
</td>
</tr>
</table>
How can I prevent a user from selecting same sort order in each row using angular js?
This plunker might help you.
First of all, genereate an array from 1 to entities.length (this case, 3).
When you select an option, tirgger the optionSelected function. This function will generate your inital array and calculate the used sortOrders by your entities. Then it filters the second ones from the first array.
HTML
<div ng-controller="EditorController">
<table>
<tr ng-repeat="x in entities">
<td>{{ x.name }}</td>
<td><select ng-model="x.sortOrder"
ng-options="col for col in sortOrderValues"
ng-change="optionSelected()">
</select>
<span ng-show="!x.sortOrder"> * sort order required</span>
</td>
</tr>
</table>
</div>
CONTROLLER
editor.controller('EditorController', function($scope) {
$scope.entities = [{name:"pencil",sortOrder:""} ,{name:"notepad",sortOrder:""} ,
{name:"bookshelf",sortOrder:""}
];
// Genereate all the numbers between 1 and $scope.entities.length
$scope.sortOrderValues= $scope.entities.map(
function (item, index) {
return index + 1;
}
);
// Function executed when you select a sortOrder
$scope.optionSelected = function () {
// Genereate all the numbers between 1 and $scope.entities.length
var allIndexes = $scope.entities
.map(function (entity, index) { return index + 1; });
// Get all the sortOrder used
var usedIndexes = $scope.entities
.map(function(e) { return e.sortOrder; });
// Remove from the [1, .., $scope.entities.length] array all the sortOrder used
$scope.sortOrderValues = allIndexes
.filter(function (order) {
return !usedIndexes.find(function(index) { return index === order; });
});
}
});

How to get the function result in ng-repeat in AngularJS?

In ng-repeat trying to display the location address by passing the latitude and longitude to a function as shown below:
$scope.address = function(lat,lng){
return reverseGeocode.geocodePosition(lat,lng, function(address){
console.log(address);
return address;
});
};
I am using reverseGeocode.geocodePosition to fetch the address and below is my view
<table class="rideTable">
<tbody>
<tr class="" ng-repeat="item in rideDetailsArray">
<td class="ridTd">
<div class="rideName">Ride {{$index + 1}}</div>
</td>
<td>
<p>Pick location : {{address(item.pick_lat,item.pick_long)}}</p>
<p>Drop location : {{address(item.drop_lat,item.drop_long)}}</p>
</td>
</tr>
</tbody>
</table>
Pick location and drop location is not displaying in the view. How can i fix this and can i get any help.
try this call function from ng-repeat
$scope.LocationNameFilter = function (id)//here pass your object id
{
if ($scope.GetLocation.length > 0) {
var SelectStream = [];
if (id) {
SelectStream = $filter('filter')($scope.GetLocation,
{ _id: id }); //some condition passing your values
}
return SelectStream[0].AddressName;
}
else {
}
};
You need to return the response as well, Change your function as
$scope.address = function(lat,lng){
return reverseGeocode.geocodePosition(lat,lng, function(address){
console.log(address);
return address;
});
};
$scope.address is a function which doesn't return anything. So, by default, the return value is undefined.
Thus, AngularJS displays it as blank in the view. You may want to change the function as below:
$scope.address = function(lat,lng){
return reverseGeocode.geocodePosition(lat,lng, function(address){
console.log(address);
return address;
});
};

Mutliplr print functionality return inconsistent data , on changing $timeout value

I want to print a multiple barcode slip, each will have different barcode.
Using a print service to print the div content,
(function() {
'use strict';
angular.module('app.services')
.factory('PrintService', PrintService);
PrintService.$inject = [];
function PrintService() {
var service = {
printElement: printElement
};
return service;
function printElement(elem) {
var printSection = document.getElementById('printSection');
// if there is no printing section, create one
if (!printSection) {
printSection = document.createElement('div');
printSection.id = 'printSection';
document.body.appendChild(printSection);
}
var elemToPrint = document.getElementById(elem);
// clones the element you want to print
var domClone = elemToPrint.cloneNode(true);
printSection.innerHTML = '';
printSection.appendChild(domClone);
window.print();
window.onafterprint = function() {
printSection.innerHTML = '';
}
};
}
})();
Using this print service, will print the slip. Slip data will bind.
var userServicePromise = UserService.printBarCodes(sampleId);
userServicePromise.then(function(response) {
if (response != null && response.data != null && response.data.result != null) {
response.data.result.forEach(function(entry) {
/* $timeout(function() {
vm.barCodeImage = angular.copy(entry);
}, 0);*/
//vm.testName = item.testMast.testName.slice(0, 3);
vm.barCodeImage = angular.copy(entry);
$timeout(function() {
PrintService.printElement("printThisElement");
}, 1);
});
} else {
toaster.error(response.data.message);
}
});
This is the html which will be printed eventually, using DOM element id for printing.
<div id="printThisElement" class="onlyprint" >
<table>
<tr>
<td>{{ ctrl.instCode }}</td>
<td align="center">{{ ctrl.date | dateDisplayFilter}} </td>
</tr>
<tr>
<td colspan="2" align="center"> <img ng-src="data:image/JPEG;base64,{{ctrl.barCodeImage}}"> </td>
</tr>
<tr>
<td colspan="2" align="center">{{ ctrl.user.name }} </td>
</tr>
<tr>
<td >Reg Id: {{ ctrl.regIdLookup }}</td>
<td align="center">{{ ctrl.testName }}</td>
</tr>
</table>
</div>
Expected out put is three slips with different barcode:
7865
7866
7867
Output is three slips with same barcode
7865
7865
7865
some times,
7866
7866
7866
On changing the $timeout(function() value output be like
7865
7865
7866
what can be the reason for this ?
Never ever modify the DOM from inside a service, that's just totally against the whole way Angular works. What you should do instead is create a model of the data (and it's quite alright to create that in the service) and use Angular's templates to render that model in the page.
The reason your code doesn't work is that you are trying to re-use vm.barCodeImage for different images on the page. Angular tracks the changes and will redraw existing parts of the page. That is why you get the same barcode repeated: the different copies each use the same model so they will be the same.
A simple solution is to create an array ofvm.barCodeImages and then just render them in an ng-repeat loop. A better way might be to create a myBarcode directive which uses UserService.printBarCodes to create one barcode in an isolated scope and then your template will look shorter and tidier.

Refreshing ng-repeat without $scope, without new request to sever

I have a table with this content:
<tbody>
<tr ng-repeat="result in ctrl.result track by $index">
<td ng-bind="$index+1"></td>
<td ng-bind="::result.title"></td>
<td> <button type="button" class="btn" ng-click='ctrl.deleteItem(result)'>Delete</button></td>
</tr>
</tbody>
And in my controller I have:
vm.deleteItem = function (result) {
myService.deleteItem(result.id)
.then(function (response) {
vm.result.splice(result, 1);
});
};
As you see, the vm.result has changed if the item be deleted successfully.
Now, the item deleted in db, so we have response and then the item has been removed from vm.result, too. But the list hasn't updated in browser.
As you see, I use controller as approach and not $scope .
Try deleting the item this way:
vm.result.splice(vm.result.indexOf(result), 1);
The first Splice parameter should be the index of element rather than element itself.
var index = vm.result.findIndex(function(item) {
if (item.id == test.id) {
return true;
}
});
if (index !== -1) {
// Removing the test from list;
vm.result.splice(index, 1);
}
check based on id from the array test.id is the id of the element u r deleting

How can I easily filter on more than one property?

Using Angular v1.5 I've got a simple one property filter working but I would like to filter on two properties. Searching came up with some custom filters but that seemed like a bunch of code to just look at an extra property.
In my below example I would like the filter to work on both FirstName and LastName.
Filter Name: <input type="text" ng-model="memberFilter.FirstName" />
<p />
<div class="table-responsive">
<table class="table table-bordered table-striped table-hover">
<tr class="info">
<th ng-click="doSort('FirstName')">First Name</th>
<th ng-click="doSort('LastName')">Last Name</th>
<th ng-click="doSort('EmailPrimary')">Email</th>
<th ng-click="doSort('PhonePrimary')">Phone</th>
<th> </th>
</tr>
<tr ng-repeat="member in members | filter:memberFilter | orderBy:sortBy:reverse">
<td>{{ member.FirstName }}</td>
<td>{{ member.LastName }}</td>
<td>{{ member.EmailPrimary }}</td>
<td class="text-center">{{ member.PhonePrimary | tel }}</td>
<td class="text-center">View</td>
</tr>
</table>
</div>
I tried adding an array to the ng-model but that didn't work:
ng-model="[memberFilter.FirstName,memberFilter.LastName]"
Updated Question
I'm new with Angular in general and just wrote my first custom filter the other day to display formatted telephone numbers. You can see my filter in the original code but I changed the name from "tel" to "phone". It's one I found on SO and I was able to get it to work. So I assumed I could just add the search filter to this file and not create a new js file for each filter. However, when I added it my Angular stopped working. I thought I added it correct but I might have a semi-colon in the wrong spot or maybe it's not possible. I still haven't figured out a good way to debug in Angular.
Here is a file I created for my filters called filter.js.
angular.module('appFilters', [])
.filter('phone', function () {
return function (phone) {
if (!phone) { return ''; }
var value = phone.toString().trim().replace(/^\+/, '');
if (value.match(/[^0-9]/)) {
return phone;
}
var country, city, number;
switch (value.length) {
case 10: // +1PPP####### -> C (PPP) ###-####
country = 1;
city = value.slice(0, 3);
number = value.slice(3);
break;
case 11: // +CPPP####### -> CCC (PP) ###-####
country = value[0];
city = value.slice(1, 4);
number = value.slice(4);
break;
case 12: // +CCCPP####### -> CCC (PP) ###-####
country = value.slice(0, 3);
city = value.slice(3, 5);
number = value.slice(5);
break;
default:
return phone;
}
if (country == 1) {
country = "";
}
number = number.slice(0, 3) + '-' + number.slice(3);
return (country + " (" + city + ") " + number).trim();
};
})
.filter('customMemberFilter', function () {
return function (memberList, query) {
// make sure a query value was passed
if (query) {
query = query.toLowerCase();
var out = [];
angular.forEach(memberList, function (member) {
if ((member.FirstName.toLowerCase().includes(query)) ||
(member.LastName.toLowerCase().includes(query))) {
out.push(member);
}
});
return out;
} else {
return memberList;
}
}
});
and this is my app.js where the appFilters are added
(function () {
var app = angular.module('troopApp', ['ngRoute','appFilters']); //('moduleName', [array of injected modules])
app.config(function($routeProvider) {
$routeProvider
.when('/', {
controller: 'MembersController',
templateUrl: 'app/views/members.html'
})
.when('/memberDetail/:memberId', {
controller: 'MemberDetailController',
templateUrl: 'app/views/memberDetail.html'
})
.otherwise({ redirectTo: '/'});
});
}());
This is what I changed my HTML code to:
Filter Name: <input type="text" ng-model="memberFilter" />
and
<tr ng-repeat="member in members | customMemberFilter:memberFilter | orderBy:sortBy:reverse">
The solution is very simple.
Change this line:
Filter Name: <input type="text" ng-model="memberFilter.FirstName" />
to this:
Filter Name: <input type="text" ng-model="memberFilter" />
By default Angular will do deep property filtering. Since you were creating an object with a FirstName property to use as your filter you were effectively limiting the filter to that property on your target object(s). By making the filter more generic Angular will attempt to match on any property of the target object(s).
Update: This will, of course, match on all properties of your member object which may be undesirable. If this is the case then, as you suspected, you'll have to write a custom filter. Here's one way you could write it:
.filter('customMemberFilter', function() {
return function(memberList, query) {
// make sure a query value was passed
if (query) {
query = query.toLowerCase();
var out = [];
angular.forEach(memberList, function(member) {
if ((member.FirstName.toLowerCase().includes(query)) ||
(member.LastName.toLowerCase().includes(query))) {
out.push(member);
}
});
return out;
} else {
return memberList;
}
}
})
And then you would use it:
<tr ng-repeat="member in members | customMemberFilter:memberFilter | orderBy:sortBy:reverse">
