AngularJS How to dynamically add HTML and bind to controller

I'm just getting started with angularJS and struggling to figure out proper architecture for what I'm trying to do. I have a single page app but the URL always should stay the same; I don't want the user to be able to navigate to any routes beyond the root. In my app, there is one main div that will need to host different views. When a new view is accessed, I want it to take over the display in the main div. Views loaded in this way can be throw-away or stick around as hidden in the DOM - I'm interested in seeing how each might work.

I've come up with a rough working example of what I'm trying to do. See working example here in this Plunk. Basically I want to dynamically load HTML into the DOM and have standard angularJS controllers be able to hook into that new HTML. Is there a better/simpler way to do this than by using the custom directive I have here and using $compile() to hook up to angular? Perhaps there's something sort of like the router, but doesn't require URL has changes to operate?

Here's the special directive I'm using so far (taken from another SO post):

// Stolen from: http://stackoverflow.com/questions/18157305/angularjs-compiling-dynamic-html-strings-from-database
myApp.directive('dynamic', function ($compile) {
  return {
    replace: true,
    link: function (scope, ele, attrs) {
      scope.$watch(attrs.dynamic, function(html) {
        if (!html) {
            return;
        }
        ele.html((typeof(html) === 'string') ? html : html.data);
        $compile(ele.contents())(scope);
      });
    }
  };
});

Thanks,

I would use the built-in ngInclude directive. In the example below, you don't even need to write any javascript. The templates can just as easily live at a remote url.

Here's a working demo: http://plnkr.co/edit/5ImqWj65YllaCYD5kX5E?p=preview

<p>Select page content template via dropdown</p>
<select ng-model="template">
    <option value="page1">Page 1</option>
    <option value="page2">Page 2</option>
</select>

<p>Set page content template via button click</p>
<button ng-click="template='page2'">Show Page 2 Content</button>

<ng-include src="template"></ng-include>

<script type="text/ng-template" id="page1">
    <h1 style="color: blue;">This is the page 1 content</h1>
</script>

<script type="text/ng-template" id="page2">
    <h1 style="color:green;">This is the page 2 content</h1>
</script>

There is a another way also

1. step 1: create a sample.html file
2. step 2: create a div tag with some id=loadhtml Eg : <div id="loadhtml"></div>

3. step 3: in Any Controller

       var htmlcontent = $('#loadhtml ');
       htmlcontent.load('/Pages/Common/contact.html')
       $compile(htmlcontent.contents())($scope);
   

This Will Load a html page in Current page

For those, like me, who did not have the possibility to use angular directive and were "stuck" outside of the angular scope, here is something that might help you.

After hours searching on the web and on the angular doc, I have created a class that compiles HTML, place it inside a targets, and binds it to a scope ($rootScope if there is no $scope for that element)

/**
 * AngularHelper : Contains methods that help using angular without being in the scope of an angular controller or directive
 */
var AngularHelper = (function () {
    var AngularHelper = function () { };

    /**
     * ApplicationName : Default application name for the helper
     */
    var defaultApplicationName = "myApplicationName";

    /**
     * Compile : Compile html with the rootScope of an application
     *  and replace the content of a target element with the compiled html
     * @$targetDom : The dom in which the compiled html should be placed
     * @htmlToCompile : The html to compile using angular
     * @applicationName : (Optionnal) The name of the application (use the default one if empty)
     */
    AngularHelper.Compile = function ($targetDom, htmlToCompile, applicationName) {
        var $injector = angular.injector(["ng", applicationName || defaultApplicationName]);

        $injector.invoke(["$compile", "$rootScope", function ($compile, $rootScope) {
            //Get the scope of the target, use the rootScope if it does not exists
            var $scope = $targetDom.html(htmlToCompile).scope();
            $compile($targetDom)($scope || $rootScope);
            $rootScope.$digest();
        }]);
    }

    return AngularHelper;
})();

It covered all of my cases, but if you find something that I should add to it, feel free to comment or edit.

Hope it will help.
