I am trying to create dynamic scope variable in angular.I am using a loop to set the variable name as v1,v2,v3 but still no success. Any idea how achieve this ?
js
for (var i = 0; i < 4; i++) {
$scope.v_i='value'+i;
}
html
<div>{{v1}}</div>
<div>{{v2}}</div>
<div>{{v3}}</div>
You can use the $scope object as typeof Array.
But I would wrap them to a $scope object wrapper items.
See both approaches below.
VIEW
<div ng-app="app" ng-controller="MainController">
{{v0}}
<br/> {{v1}}
<br/> {{v2}}
<br/> {{v3}}
<br/>
<br/> {{items}}
<br/>
<br/>
<div ng-repeat="item in items">
{{item}}
</div>
</div>
CONTROLLER
angular
.module('app', [])
.controller('MainController', MainController)
function MainController($scope) {
$scope.items = {};
for (var i = 0; i < 4; i++) {
$scope['v' + i] = 'value' + i;
// or add to object wrapper
$scope.items['v' + i] = 'value' + i;
}
}
$scope['v' + i]. Also, saying you're using it as Array might be a bit misleading. You're using bracket notation on an object.
_ on controller and view. But the approach is identical... As updated on above answer.
'value' + i is supposed to do? I'm not sure the purpose of that line. Thank you!
