Insert HTML into view

Question

Is it possible to create an HTML fragment in an AngularJS controller and have this HTML shown in the view?

This comes from a requirement to turn an inconsistent JSON blob into a nested list of id : value pairs. Therefore the HTML is created in the controller and I am now looking to display it.

I have created a model property, but cannot render this in the view without it just printing the HTML.

---

Update

It appears that the problem arises from angular rendering the created HTML as a string within quotes. Will attempt to find a way around this.

Example controller :

var SomeController = function () {

    this.customHtml = '<ul><li>render me please</li></ul>';
}

Example view :

<div ng:bind="customHtml"></div>

Gives :

<div>
    "<ul><li>render me please</li></ul>"
</div>

Answer 1

Here's a simple (and unsafe) bind-as-html directive, without the need for ngSanitize:

myModule.directive('bindAsHtml', function () {
    return {
        link: function (scope, element, attributes) {
            element.html(scope.$eval(attributes.bindAsHtml));
        }
    };
});

Note that this will open up for security issues, if binding untrusted content.

Use like so:

<div bind-as-html="someHtmlInScope"></div>

Answer 2

For Angular 1.x, use ng-bind-html in the HTML:

<div ng-bind-html="thisCanBeusedInsideNgBindHtml"></div>

At this point you would get a attempting to use an unsafe value in a safe context error so you need to either use ngSanitize or $sce to resolve that.

$sce

Use $sce.trustAsHtml() in the controller to convert the html string.

 $scope.thisCanBeusedInsideNgBindHtml = $sce.trustAsHtml(someHtmlVar);

ngSanitize

There are 2 steps:

1. include the angular-sanitize.min.js resource, i.e.:
   <script src="lib/angular/angular-sanitize.min.js"></script>

2. In a js file (controller or usually app.js), include ngSanitize, i.e.:
   angular.module('myApp', ['myApp.filters', 'myApp.services', 'myApp.directives', 'ngSanitize'])

Answer 3

you can also use ng-include.

<div class="col-sm-9 TabContent_container" ng-include="template/custom.html">
</div>

you can use "ng-show" to show hide this template data.

Answer 4

You can also create a filter like so:

var app = angular.module("demoApp", ['ngResource']);

app.filter("trust", ['$sce', function($sce) {
  return function(htmlCode){
    return $sce.trustAsHtml(htmlCode);
  }
}]);

Then in the view

<div ng-bind-html="trusted_html_variable | trust"></div>

Note: This filter trusts any and all html passed to it, and could present an XSS vulnerability if variables with user input are passed to it.

Answer 5

Just did this using ngBindHtml by following angular(v1.4) docs,

<div ng-bind-html="expression"></div> 
and expression can be "<ul><li>render me please</li></ul>"

Make sure you include ngSanitize in the module's dependencies. Then it should work fine.
