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:

Answer 1

This method uses jqueries contents().unwrap().

1. First, detect the paste event
2. Add a unique class to the tags that are already in the element into which we are pasting.

3. After a given timeout scan through all the contents unwrapping tags that don't have the class that you set earlier. Note: This method does not remove self closing tags like
   See an example below.

   //find all children .find('*') and add the class .within .addClass("within") to all tags
   $('#answer_text').find('*').each(function () {
   $(this).addClass("within");
   });
   setTimeout(function() {
   $('#answer_text').find('*').each(function () {
       //if the current child does not have the specified class unwrap its contents
       $(this).not(".within").contents().unwrap();
   });
   }, 0);
