javascript - How to make ng-bind-html compile angularjs code

Question

I am working with angularjs 1.2.0-rc.3. I'd like to include html code into a template dynamically. For that I use in the controller :

html = "<div>hello</div>";
$scope.unicTabContent = $sce.trustAsHtml(html);

In the template I got :

<div id="unicTab" ng-bind-html="unicTabContent"></div>

It works fine for regular html code. But when I try to put angular template it is not interpreted, it is just included in the page. For example I'd like to include :

<div ng-controller="formCtrl">
    <div ng-repeat="item in content" ng-init="init()">
    </div>
</div>

Thanks a lot

This solution doesn't use hardcoded templates, and you can compile Angular expressions embedded within an API response.

Step 1. Install this directive: https://github.com/incuna/angular-bind-html-compile

Step 2. Include the directive in the module.

angular.module("app", ["angular-bind-html-compile"])

Step 3. Use the directive in the template:

<div bind-html-compile="letterTemplate.content"></div>

Result:

Controller Object

 $scope.letter = { user: { name: "John"}}

JSON Response

{ "letterTemplate":[
    { content: "<span>Dear {{letter.user.name}},</span>" }
]}

HTML Output =

<div bind-html-compile="letterTemplate.content"> 
   <span>Dear John,</span>
</div>

For reference sake, here's the relevant directive:

(function () {
    'use strict';

    var module = angular.module('angular-bind-html-compile', []);

    module.directive('bindHtmlCompile', ['$compile', function ($compile) {
        return {
            restrict: 'A',
            link: function (scope, element, attrs) {
                scope.$watch(function () {
                    return scope.$eval(attrs.bindHtmlCompile);
                }, function (value) {
                    element.html(value);
                    $compile(element.contents())(scope);
                });
            }
        };
    }]);
}());
