ng-repeat finish event

I want to call some jQuery function targeting div with table. That table is populated with ng-repeat.

When I call it on

$(document).ready()

I have no result.

Also

$scope.$on('$viewContentLoaded', myFunc);

doesn't help.

Is there any way to execute function right after ng-repeat population completes? I've read an advice about using custom directive, but I have no clue how to use it with ng-repeat and my div...

Solution 1:

Indeed, you should use directives, and there is no event tied to the end of a ng-Repeat loop (as each element is constructed individually, and has it's own event). But a) using directives might be all you need and b) there are a few ng-Repeat specific properties you can use to make your "on ngRepeat finished" event.

Specifically, if all you want is to style/add events to the whole of the table, you can do so using in a directive that encompasses all the ngRepeat elements. On the other hand, if you want to address each element specifically, you can use a directive within the ngRepeat, and it will act on each element, after it is created.

Then, there are the $index, $first, $middle and $last properties you can use to trigger events. So for this HTML:

<div ng-controller="Ctrl" my-main-directive>
  <div ng-repeat="thing in things" my-repeat-directive>
    thing {{thing}}
  </div>
</div>

You can use directives like so:

angular.module('myApp', [])
.directive('myRepeatDirective', function() {
  return function(scope, element, attrs) {
    angular.element(element).css('color','blue');
    if (scope.$last){
      window.alert("im the last!");
    }
  };
})
.directive('myMainDirective', function() {
  return function(scope, element, attrs) {
    angular.element(element).css('border','5px solid red');
  };
});

See it in action in this Plunker. Hope it helps!

Solution 2:

If you simply want to execute some code at the end of the loop, here's a slightly simpler variation that doesn't require extra event handling:

<div ng-controller="Ctrl">
  <div class="thing" ng-repeat="thing in things" my-post-repeat-directive>
    thing {{thing}}
  </div>
</div>

function Ctrl($scope) {
  $scope.things = [
    'A', 'B', 'C'  
  ];
}

angular.module('myApp', [])
.directive('myPostRepeatDirective', function() {
  return function(scope, element, attrs) {
    if (scope.$last){
      // iteration is complete, do whatever post-processing
      // is necessary
      element.parent().css('border', '1px solid black');
    }
  };
});
