I know, this thing has been asked like 2 trillion times, but i cannot still get done. the iframes are generated dynamically inside the source which I get from external feed. 

my jquery is: 

```
$(function(){
   $('iframe').each(
      function(index, elem) {
         elem.setAttribute("width","250");
      }
   );
});

```

this code is not being able to set the width of iframe.

and one more thing: I inspected the iframe attributes, and there are NOT editable in browser unlike other css style - **which means, my jquery cannot also set it after DOM is ready**

what the heck? is there any workaround for this?
