Topic awaiting preservation: Anchor Tag - onclick event w/no parent window refresh

Hello,

This onclick event causes the containing page to refresh even though the return value is 0, and the jscript is only suppose to launch a new window. How do I eliminate the main page from refreshing?

<a href="#" onclick="promoteevent(); return 0;">- Click Here For More Information -</a>

Give this a try:

<a href="javascript:void(0);" onclick="promoteevent();">- Click Here For More Information -</a>

Or:

<a href="javascript:promoteevent();">- Click Here For More Information -</a>

Hey that works! For some reason, I was under the impression that "return 0;" was sufficient in the onclick event or that you could do something like "return(promoteevent()); where promoteevent() always returned 0.

Return false, not 0.


 

For compatibility the check for the return value to cancel a default action is strict. It must be the false value and nothing else. The reason is that the default value of a function return is undefined, which autocasts to false, and thus they couldn't allow autocasting since that would mean any function that doesn't return a value cancels the default event.
