I'm using AngularJS for binding JS variables to my HTML content, and it works fine.
JS
var app = angular.module("Tabs", [])
.controller("TabsController", ['$scope', function($scope){
$scope.events = my_JS_object;
})
HTML
<div>{{events.test}}</div>
It works as long as my_JS_object.test is a simple string, like "Hello World", but once I try to put HTML tag in there, such as Hello <b>World</b> It doesn't use the tags as HTML elements, but as simple text. Which makes sense, only I have no idea how to make the HTML tags work.

Reset to default 4As stated by Angular documentation, you can use inbuilt ng-bind-html directive to evaluate model string and insert resulting HTML into element.
Example: If you have model value like:
$scope.myHTML =
'I am an <code>HTML</code>string with ' +
'<a href="#">links!</a> and other <em>stuff</em>';
Use ng-bind-html like:
<p ng-bind-html="myHTML"></p>
For detailed information go through: https://docs.angularjs/api/ng/directive/ngBindHtml
Note: Don't forget to inject ngSanitize service in your app.
You need to use the ngBindHtml directive that properly evaluates the expression and inserts the resulting HTML into the element in a secure way. To do this, you must include a reference to angular-sanitize.js in your HTML and then in your angular module, inject ngSanitize.
Like so
var app = angular.module("Tabs", ['ngSanitize'])
.controller("TabsController", ['$scope', function($scope){
$scope.events = my_JS_object;
})
<div ng-controller="TabsController">
<div ng-bind-html="events.test"></div>
</div>
Here is a full working example:
(function(angular) {
'use strict';
angular.module('bindHtmlExample', ['ngSanitize'])
.controller('ExampleController', ['$scope', function($scope) {
$scope.myHTML = 'Hello This is <b>BOLD<b/>';
}]);
})(window.angular);<head>
<script src="//ajax.googleapis./ajax/libs/angularjs/1.5.0-beta.1/angular.min.js"></script>
<script src="//ajax.googleapis./ajax/libs/angularjs/1.5.0-beta.1/angular-sanitize.js"></script>
</head>
<body ng-app="bindHtmlExample">
<div ng-controller="ExampleController">
<p ng-bind-html="myHTML"></p>
</div>
</body>Refer to the official angular documentation for details: https://docs.angularjs/api/ng/directive/ngBindHtml
If you want to insert HTML into page you shouldn't do it this way. There is sanitize for this task. For example in your controller:
$scope.trustedHtml = "<b>Hello World</b>"
And in your html:
<div ng-bind-html="trustedHtml "></div>
Always check html if using a user given text before inserting.
Also don't forget to add ngSanitize as dependency while creating controller
It's easier to use transclusion if you want to embed custom HTML into your DOM tree.
angular.module('myApp', [])
.controller('MainCtrl', function ($scope) {
$scope.overwrite = false;
$scope.origin = 'parent controller';
})
.directive('myDirective', function() {
return {
restrict: 'E',
templateUrl: 'my-directive.html',
scope: {},
transclude: true,
link: function (scope) {
scope.overwrite = !!scope.origin;
scope.origin = 'link function';
}
};
});<script src="https://code.angularjs/1.3.2/angular.min.js"></script>
<div ng-app="myApp">
<div ng-controller="MainCtrl">
<my-directive>
<p>HTML template</p>
<p>Scope from {{origin}}</p>
<p>Overwritten? {{overwrite}}</p>
</my-directive>
</div>
<script type="text/ng-template" id="my-directive.html">
<ng-transclude></ng-transclude>
<hr />
<p>Directive template</p>
<p>Scope from {{origin}}</p>
<p>Overwritten? {{overwrite}}</p>
</script>
</div>
