Couple of questions

	detach events how?

I currently don't use any librarys although of course i could
If i was just to create an event attachment method any pointers on good
examples to look at?

Hi Shaun,

When you replace the link, you introduce a brand new  element to the  DOM
The old link and hence its old event attachments are not available any more.


1. You should detach all event handlers *before* altering the element (due
to memory leakage and closure issues -- good boys clean up their mess.)
2. Insert new element to DOM via appendChild or something similar (or for
the lazy men out there; setting the innerHTML of the container parent)
3. re-attach the event handler with your favorite event attachment method of
your favorite library.
