Detect outerHeight() of element with ng-repeat

问题

I'm trying to detect the height of an element that will change depending on data from a database.

I have used .outerHeight successfully before but can't do this on an element that contains data from a ng-repeat.

Is there a way to do this once the data has populated the angular element or is there another method of detecting this?

Yes, you need to create an attribute directive and put it on the ng-repeat.

<div ng-repeat="whatever in items" outer-height></div>

The directive will have a link function which happens after it has compiled.

app.directive('outerHeight', function(){
  return{
    restrict:'A',
    link: function(scope, element){
       //using outerHeight() assumes you have jQuery
       //use Asok's method in comments if not using jQuery
       console.log(element.outerHeight()); 
    }
  };
});

Here's a Plnkr which will log the outerHeight to console: http://plnkr.co/edit/AdGpnzJilW2179Ybuurk?p=preview

Note You will need to use a $watch and get a new height if data changes.
