Compile dynamic template from outside of angular.

Compile dynamic template from outside of angular

I want to load dynamic HTML content via AJAX, then compile it, because it contains angular directives.

<!DOCTYPE html>
<html ng-app="app">
<head>
	<title>Compile dynamic HTML</title>
	<script type="text/javascript" src="js/jquery-1.11.0.js"></script>
	<script type="text/javascript" src="js/angular.js"></script>
</head>
<body ng-controller="TestCtrl">

<div obj></div>

<button class="foo">Change</button>

<script type="text/javascript">
	var app=angular.module('app',[]);
	app.controller('TestCtrl',function($scope){});

	jQuery(document).ready(function($){
		$('.foo').on('click',function(e){
		  // todo: load HTML content via AJAX or generate via jQuery
		  // todo: compile new HTML content, which contains Angular directives
		});
	});
</script>
</body>
</html>

We can get reference to $compile outside of angular via injector().invoke().

	jQuery(document).ready(function($){
		$('.foo').on('click',function(e){
			e.preventDefault();
			angular.element(document).injector().invoke(function($compile){
				var obj=$('[obj]'); // get wrapper
				var scope=obj.scope(); // get scope
				// generate dynamic content
				obj.html($('<input type="text" ng-pattern="/^([0-9]+)$/" ng-model="test"><span>{{test}}</span>'));
				// compile!!!
				$compile(obj.contents())(scope);
			});
		});
	});

This is good, thank you. My only issue is that I can't get it too work with Angular form validation and it also throws the following error:

TypeError: text.indexOf is not a function .. at $interpolate

And same issue with not being able to use it with ng-include, unfortunately.

Sorry, this way cannot work in my scenario.
Current Page:
<html>
<head>test</head>
<body ng-app="core">
<div id="AjaxContent"></div>
<input type="button" id="loadContentButton" />
<script> var coreModule = angular.module("core", []); var module = angular.module("myTest", []);
module.controller("MyTestController", ["$scope", function($scope) {}]);

$(function() {
$("#loadContentButton").on("click", function() {
$.ajax({
url: "AjaxContent.html",
success: function(view) {
var ajaxContentElement = $("#AjaxContent");
ajaxContentElement .html(view);
angular.element(ajaxContentElement ).injector().invoke(["$compile", function ($compile) {
var scope = ajaxContentElement .scope();
$compile(ajaxContentElement )(scope);
scope.$apply();
}]);
}
});
});
});
</script>
</body>
Ajax Content:
<div ng-app="myTest" ng-controller="MyTestController">
this is my test page.
</div>

This will throw the js error:
Uncaught Error: [$injector:unpr] Unknown provider: lengthCountLeftFilterProvider <- lengthCountLeftFilter

Please help anyone can.Thx so much!
