Can I get the compiled html of an Angular element?

Question

I have compiled an element using the $compile service. If I add that directly to the DOM, it looks great and all of the bindings are correct. If I want that element as a string though, it shows {{stuffHere}} instead of the bindings. Is there a way to get the html of the element after it's compiled?

$templateCache.put('template', '<div><div><div><span>content is {{content}}</span></div></div>   </div>');

$scope.content = 'Hello, World!';

var el = $compile($templateCache.get('template'))($scope);
$('body').append(el);

alert(el.html());

The element appended to the body shows content is Hello, World!

The alert shows <div><div><span ng-binding>{{content}}</span></div></div>

What I would like to see out of the alert is <div><div><span ng-binding>Hello World</span></div></div>

The issue is you're reading the contents of the element too early. If you add a $timeout to your read it will be correct:

angular.module('demo', []);
angular.module('demo').controller('PopoverDemoCtrl', function($scope, $timeout, $compile, $templateCache) {
  $templateCache.put('template', '<div><div><div><span>content is {{content}}</span></div></div></div>');

  $scope.content = 'Hello, World!';

  var el = $compile($templateCache.get('template'))($scope);
  $('body').append(el);
  $timeout(function() {
    console.log(el.html());
  }, 300);   // wait for a short while
});

Why is $timeout required?

After the $compile method is called it will not immediately take effect. This is due to the $digest cycle, since it uses the $scope it needs to run the $digest cycle to see if anything has affected $scope.content. This is why you have to set a $timeout, you need to wait until the $digest cycle completes before the element's content actually gets changed. You can read a bit more about how this all ties together here.

I am needing your help. I want the data after binding, too. but i still get {{ xxxx.xxx }} in ng-repeat. any solutions? – Watkins

@chournsolidet Can you clarify? I'm unsure what you mean. – Ortrude

i have my template by getting from view. var table = document.getElementById('my-table').outerHTML; $templateCache.put('template', table); and i put everything like the answer above. The point is that when i have ng-repeat to loop my td of my table already in the view. then i just get my table by id. it doesn't give me the rendered table but with {{ xxxx.xxxx }} instead. – Watkins

by running your code, i still get this " <div><div><span class="ng-binding">content is {{content}}</span></div></div> " in console log. All i want is " <div><div><span class="ng-binding">content is Hello, World! </span></div></div> " in console log – Watkins
