insert an iframe into page dynamically in AngularJ

问题:

I am trying to dynamically insert an iframe into a page with Angular 1.2. Here is the code:

html:

<div id="player_wrapper" ng-cloak>
    <div ng-bind-html="player"></div>
</div>

js:

$http({method: 'GET', url: url}).
    success(function(data, status) {
        $scope.player = data.html;
    }.......

So the data.html is a string that has a valid HTML starting with

<iframe ...>

The string contains also some div. So it could look like:

<iframe src='...' ...></iframe><div>some stuf</div>

I use in app.js 'ngSanitize'. What it shows is the div (after the iframe) but not the iframe itself.

If I use jQuery, basically a

$(#'player_wrapper').html(data.html)

works fine... but trying to make it proper angularJS.

Any idea on why only the divs after the iframe are being displayed?

Many thanks all

ngBindHtml will pass your HTML through $sce.getTrustedHtml before displaying it. I suspect this is what would be removing your iframe.

According to the docs you can use $sce.trustAsHtml to avoid this check so long as you fully trust any HTML coming from this source - an iframe from an untrusted source could likely do a number on nasty things to visitors to your page.

$http({method: 'GET', url: url}).
    success(function(data, status) {
        $scope.player = $sce.trustAsHtml(data.html);
    }.......

Be careful! :)

You need to use the $sce service as desribed in the documentation of ng-bind-html:

$scope.player = $sce.trustAsHtml('your html goes here');

See this plunk for an example:

After much trouble I managed to get a nice setup going where I can dynamically load iframes into my page and pass information through to it.

I made this a github project. It uses a single directive for passing raw input element information, and also uses ngSanatize for the $sce.trustAsResourceUrl function.

Here is the live demo
