Remove the ng-click event listener from an element using AngularJS dynamically

Remove the ng-click event listener from an element using AngularJS dynamically

I have an element with an ng-click event that, when clicked, adds a div which works fine. My goal is to remove the ng-click event after adding the div.

One solution 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>

However, using this method requires adding multiple divs for a single element that toggles on and off. Is there any way to dynamically unbind a click event like we do in jQuery?

Any assistance would be greatly appreciated.

Here's another way to achieve the same result:

<div ng-click="!addedDiv && addNewDiv()" >                   
    <span>Click here to add a new div</span> 
</div>

By using this code, the function addNewDiv() will only be called if the variable addedDiv is false.

Implementing that logic in the controller is best practice, rather than embedding it directly into the view.

Controller:

(function(){

function divController() {
    var self = this;

    self.divAdded = false;

    self.addDiv = function() {
        if(!divAdded) { 
            //Code to add div should go here
            self.divAdded = true;
        }
    }
}

angular.module("example")
.controller("divAddController", divController);

})();

View:

<div ng-controller="divAddController as divHelper">
    <div ng-click="divHelper.addDiv()" ng-class="{disabled: divHelper.divAdded}">
        <span>Click to add a div</span>
    </div>
</div>

If you want to simplify the process, consider this alternative approach:

var app = angular.module('app', []);

app.controller('MainCtrl', function($scope) {
  $scope.displayDiv = false;
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app="app" ng-controller="MainCtrl">
  <button ng-click="displayDiv = true;">Click to show div</button>
  <div ng-if="displayDiv">This is visible!</div>
</div>
