Unbind ng-click dynamically from element: angularjs
I have an element that has an ng-click event and when clicked it adds a div which works great. i want to remove ng-click after div is added.
one way is to use ng-if
<div ng-click="addDiv()" ng-if="!divAdded" >
<span>i add a div</span>
</div>
<div class="disabled" ng-if="divAdded" >
<span>i add a div</span>
</div>
for this i have to add multiple divs for one element that works on and off. is there a way to disable the click event like we do in jquery dynamically?
any help would be appreciated

Put this logic in controller
, not inview
Controller:
(function(){
function divAddController() {
var self = this;
self.divAdded = false;
self.addDiv = function() {
if(!divAdded) {
//Add div here
self.divAdded = true;
}
}
}
angular.module("example")
.controller("divAddController", divAddController);
})();
View:
<div ng-controller="divAddController as divAdder">
<div ng-click="divAdder.addDiv()" ng-class="{disabled: divAdder.divAdded}">
<span>i add a div</span>
</div>
</div>

You can do it in an easier way:
var myApp = angular.module('myApp', []);
myApp.controller('MyCtrl', function($scope) {
$scope.showDiv = false;
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MyCtrl">
<button ng-click="showDiv = true;">I show the div</button>
<div ng-if="showDiv">I am visible!</div>
</div>
