[Javascript] IE onclick problem

[Cutter (JSRelated)]

That's the point, in this case/usage you don't.

Here's what I mean. It's exactly like doing form validation. You have a 
form.submit() event, which you override in some way by saying "do all of 
this. Oh wait, that failed, so we have to stop." Your validation methods 
return false to the submit method itself, stopping it from performing 
it's default 'submit' action. Or, your validation methods all return 
true, ultimately passing that to the 'submit' event, allowing it to 
complete it's default action. The 'click' handler works the same way. By 
specifying 'true' or 'false' in your onclick attribute, you are just 
telling the click event whether it should do it's default 'click' 
action, or just stop right there. Any logic/process/programmatic magic 
you are doing (or want to do) should happen, then return a true or false 
to the click handler so that it knows to stop or continue.

This is why I started using JQuery. Makes these things really simple.
