Catch paste input

Question

I\'m looking for a way to sanitize input that I paste into the browser, is this possible to do with jQuery?

I\'ve managed to come up with this so far:

This is getting closer to what you might want.

function sanitize(s) {
  return s.replace(/\bfoo\b/g, "~"); 
};

$(function() {
 $(":text, textarea").bind("input paste", function(e) {
   try {
     clipboardData.setData("text",
       sanitize(clipboardData.getData("text"))
     );
   } catch (e) {
     $(this).val( sanitize( $(this).val() ) );
   }
 });
});

Please note that when clipboardData object is not found (on browsers other then IE) you are currently getting the element's full value + the clipboard'ed value.

You can probably do some extra steps to dif the two values, before an input & after the input, if you really are only after what data was truly pasted into the element.
