Hi,
I'm trying to make a link that changes my web page into a printable format and back:

<a id="print" href="#" title="Print map">Printable version</a>

The switch to printable format works fine:

$('#print').click(function() {
	$('img').attr('src', newsrc);
	$(this).html('Screen version');
	$(this).attr('id', 'screen');
	return false;
});

But going back, it doesn't work at all. Of course, .click() won't work because the element gets id "screen" only after the link is clicked. I tried using .live() , but this didn't work either:

$('#screen').live("click", function() {
	$('img').attr('src', oldsrc);
	$(this).html('Printable version');
	$(this).attr('id', 'print');
	return false;
});

I've since solved the problem by just using a flag for the single first event handler instead of making two event handlers and switching the ID for the link to call each. But I want to know how to fix this in case I have this problem some other time where it's not as simple to just use a flag.

I've tried this, and it works.

I see. so you need to use .live() for both clicks, not just the second. Makes sense. Great, thanks for your help!
