i have two divs i want to show them conditionally with onclick event .

my-angular-app.js

$(document).on('click', '#showless', function(el) {
 var appElement = document.querySelector('[ng-app=myapp]');
 var $scope = angular.element(appElement).scope();
  $scope.$apply(function() {
      $scope.value = false;
    });

});

$(document).on('click', '#showmore', function(el) {
  var appElement = document.querySelector('[ng-app=myapp]');
  var $scope = angular.element(appElement).scope();
  $scope.$apply(function() {
       $scope.value = true;
 });

});

and my div of myapp (myapp.html)

    <div ng-show="desc" id="description" class="text-muted" style="padding-top:5px;padding-left:10px;padding-right:10px;color:#2E2E2E;font-size:11px;">{{myapp.value|truncate}}<span><a id="showmore" href="">more</a></span>
    </div>
    <div ng-show="!desc" id="description" class="text-muted" style="padding-top:5px;padding-left:10px;padding-right:10px;color:#2E2E2E;font-size:11px;">{{myapp.value}}<span><a id="showless" href="">less</a></span>
    </div>

(truncate is a filter i wrote which works fine .)

I'm not exactly sure what you are trying to do, but Angular provides ng-click, so you should not have to bind to $(document).on('click').

I'd suggest a simpler approach for conditional show:

<div ng-show="desc" id="description" class="text-muted" style="padding-top:5px;padding-left:10px;padding-right:10px;color:#2E2E2E;font-size:11px;">{{myapp.value|truncate}}<span><a id="showmore" ng-click="desc = true" href="#">more</a></span>
    </div>
    <div ng-show="!desc" id="description" class="text-muted" style="padding-top:5px;padding-left:10px;padding-right:10px;color:#2E2E2E;font-size:11px;">{{myapp.value}}<span><a id="showless" ng-click="desc = false" href="#">less</a></span>
    </div>

The above uses ng-click to set the value of desc. Therefore, you don't need any other logic in the controller to toggle the divs.
