Question

Is there any way to remove all the javascript events from the html tags?

For example

<img src=" " onclick="" />
<img src=" " onerror="" />

I want to strip onclick and onerror from these tags. As in the example, I want to strip all the javascript events from the html tags.

Answer 1

You can do this to clear the events :

// get all img elements
var imgElements = document.getElementsByTagName('img');
// loop elements
for (var i = 0; i < imgelements.length; i++) { 
  // clear handler
  imgElements[i].onclick = null;
  // add other handlers here
  // imgElements[i].<here> = null;
}

Docs for getElementsByTagName() here

Update 1 – All elements on document

If you want to get all of the elements on the document then use document.getElementsByTagName('*')

Update 2 – All events
