Read html text from variable

Question

I have a JS variable that holds html code for embedding a YouTube video, which looks like:

<iframe width="560" height="315" src="https://www.youtube.com/embed/....." 
frameborder="0" allowfullscreen></iframe>

Is there any way to simply read the html from the variable? Or must I extract the URL from the variable and surround it with the iframe tag framework?

If you're talking about reading the HTML code inside the iframe, then you can't do that with JavaScript: take a look here for more information.

If you want to add the frame on your document you can do it using the innerHTML property of an element, for example:

var myFrame = '<iframe width="560" height="315" src="https://www.youtube.com/embed/....." frameborder="0" allowfullscreen></iframe>'

document.getElementById("container-id").innerHTML += myFrame;

If your HTML have following tag you need to add "id" as a attribute.

<iframe width="560" height="315" src="https://www.youtube.com/embed/....." frameborder="0" allowfullscreen id="iframe1"></iframe>

You can read properties in this way:

document.getElementById('iframe1').getAttribute('frameborder')

Here's a working code

<body>
<div id="DIV">
</div>
<script type="text/javascript">    
   var content = document.getElementById('DIV');
   var frame = "<iframe width='560' height='315' src='https://www.youtube.com/embed/.....'
frameborder='0' allowfullscreen></iframe>"
   content.innerHTML = frame ;   
</script>
</body>
