wrap() evaluates scripts

Calling .wrap() will evaluate any scripts inside the element. This can cause problems when the browser has already run the scripts once. If this isn't considered a bug, it ought to be be mentioned in the documentation for wrap().

Workaround: manually do .remove('script') prior to using .wrap().

Regarding the workaround, .remove('script') doesn't seem to work although .find('script').remove() does.

The only way I can think of to fix this is to add an optional argument to domManip (the function that wrap ultimately relies upon) and then do something like:

if ( !ignoreScripts && scripts.length ) {
  jQuery.each( scripts, evalScript );

Does this seem reasonable? If so, I'm happy to write a patch.

Actually, it looks like wrap first reloads the script tags and only then removes them.

If you wrap an element containing a script element once, it is executed. You can now inspect the DOM and will find out the script element is missing. Thus, if you try to wrap the same element once more, the script is not executed.

Is there any reason to execute the scripts when the first wrap() is called, if it is always removed from the DOM by the same call?


Tested in FF 8, Chrome 15, jQuery 1.7.1 and jQuery 1.4.1
