What I am trying to implement is basically a "on ng repeat finished rendering" handler. I am able to detect when it is done but I can't figure out how to trigger a function from it.
Check the fiddle:http://jsfiddle.net/paulocoelho/BsMqq/3/
JS
var module = angular.module('testApp', [])
.directive('onFinishRender', function () {
return {
restrict: 'A',
link: function (scope, element, attr) {
if (scope.$last === true) {
element.ready(function () {
console.log("calling:"+attr.onFinishRender);
// CALL TEST HERE!
});
}
}
}
});
function myC($scope) {
$scope.ta = [1, 2, 3, 4, 5, 6];
function test() {
console.log("test executed");
}
}
HTML
<div ng-app="testApp" ng-controller="myC">
<p ng-repeat="t in ta" on-finish-render="test()">{{t}}</p>
</div>
Answer: Working fiddle from finishingmove: http://jsfiddle.net/paulocoelho/BsMqq/4/
var module = angular.module('testApp', [])
.directive('onFinishRender', function ($timeout) {
return {
restrict: 'A',
link: function (scope, element, attr) {
if (scope.$last === true) {
$timeout(function () {
scope.$emit(attr.onFinishRender);
});
}
}
}
});
Notice that I didn't use .ready()
but rather wrapped it in a $timeout
. $timeout
makes sure it's executed when the ng-repeated elements have REALLY finished rendering (because the $timeout
will execute at the end of the current digest cycle -- and it will also call $apply
internally, unlike setTimeout
). So after the ng-repeat
has finished, we use $emit
to emit an event to outer scopes (sibling and parent scopes).
And then in your controller, you can catch it with $on
:
$scope.$on('ngRepeatFinished', function(ngRepeatFinishedEvent) {
//you also get the actual event object
//do stuff, execute functions -- whatever...
});
With html that looks something like this:
<div ng-repeat="item in items" on-finish-render="ngRepeatFinished">
<div>{{item.name}}}<div>
</div>
