Remove iframe with javascript

Pure Javascript code:

document.querySelectorAll('iframe').forEach(
  function(elem){
    elem.parentNode.removeChild(elem);
});

Here's a script you can run that will remove all the iframes from your document. Here's an example of this working: http://jsfiddle.net/5hh9H/

var iframes = document.querySelectorAll('iframe');
for (var i = 0; i < iframes.length; i++) {
    iframes[i].parentNode.removeChild(iframes[i]);
}
