Inside your directive link function:

app.directive("scrollHeightDetector", function() {
     return {
       restrict : "AEC",
       link : function(scope, element, attrs) {
           // here you can use element to get the height

           var height = element[0].scrollHeight;


        }
    }
});

Thanks, it works. why it works use element[0] but got undefined when call element.scrollHeight directly?

jamie2015: element here is a jQuery (or jqLite) object which responds to array indexing. The actual DOM object is the first item in the array.
