disable all javascript events on page

I am trying to write a chrome extension that disables event listeners for all elements (mouseover, click, ...) I am not trying to rewrite noscript, this is just a setup step that i need.

I have tried $("body *).unbind() and .unbind("mouseover click") and .off() and .off("mouseover click") none worked.

What am i doing wrong?

PS: it would also be fine to just disable all javascript code (coming from the page itself) from running on the page and only allow my extension injected code

This is not a complete example, as I won't do all of your work for you, but might lead you in the right direction:

function preventAll(){
  var dom = document.getElementsByTagName('*');
  var km = ['click', 'dblclick', 'mousedown', 'mousemove', 'mouseover', 'mouseout', 'mouseup', 'mouseenter', 'mouseleave', 'keydown', 'keypress', 'keyup'];
  for(var i=0,l=dom.length; i<l; i++){
    for(var n=0,c=km.length; n<c; n++){
      dom[i]['on'+km[n]] = function(e){
        e = e || event;
        e.preventDefault();
        return false;
      }
    }
  }
  var fr = frames;
  for(var i=0,l=fr.length; i<l; i++){
    // cancell frames events here
  }
}

If you have events made by jQuery as you say, it keeps around the data that you can parse out. You can see how the excellent Visual Events does it, as a more general solution (i.e. outside Chrome extensions).

It's not possible to intercept or list all previously-chained events in Javascript. However, it does look like Chrome plugins specifically (as opposed to the DOM in general) have an API for manipulating how Javascript works.
