What is the best practice creating IFRAME using JavaScript?

Question

What is the best practice creating an iframe HTML element using JavaScript?

 var iframe = document.createElement("iframe");
 iframe.setAttribute("sandbox", "")
 iframe.setAttribute("src", url);

I faced the question while developing Firefox plugin, but usage is quite the same as developing a web page. I do not use jQuery.

You can try like this:-

<script type="text/javascript">
function abc() {
  iframe = document.createElement("IFRAME");
  iframe.setAttribute("src", "http://example.com/");
  iframe.style.width = "640px";
  iframe.style.height = "480px";
  document.body.appendChild(iframe);
}
</script>

No problem ;) One question though, why do you write 640+"px" instead of "640px" directly?

should I use sandbox attribute? Other HTML5 features?

Rahul Tripathi Over a year ago

Yes you can use. The sandbox attribute enables a set of extra restrictions for the content in the inline frame. NOTE:- The sandbox attribute is not supported in Internet Explorer 9 and earlier versions, or in Opera.
