difference between javascript:null(0) and #

Hi,
I know that when you use <a href="javascript:null(0)" onClick="open_win()">, it will not refresh the original page but just open the new window.

But when you use "<a href="#" onClick="open_win()">", does this refresh the original page and then open a new window??

Also does the first option work in some versions of IE (example 5.5 but not in 5.0) only??
Could you tell me which option would work in any version of IE??

Thanks for any replies.

Regards,

Yoshi

Me again.

Here's the lowdown:

1)User clicks on link.
2)onclick handler executes.
3)Unless click event is then explicitly cancelled - by a) returning false, b) cancelling the bubbling of the event (IE/NS6), c) setting the event's returnValue - a property - to false - or d) some other new ways with the latest event model,
4)href is loaded.

If href="#", the hash mark indicates an anchor; since no anchor name is specified, it takes you to the top of the current page (with a reload). Not sure about the IE version question, but

<a href="#" onClick="open_win();return false;">

should work anywhere JavaScript/JScript is enabled.

adios

Adios,
Thanks for your reply. Most of it made sense. I was under the impression that javascript:null(0) worked in any browser version too.

Anyway no worries, problem solved and learned something too.

Later,

javascript:void(0) might; javascript:; (a MM fave) is sometimes used too...just return false; Yoshi, kills events like rat poison...
