Changing href dynamically

[Matt Richardson]

Hi - I'm trying to use some Javascript validation before letting the user validate away from a JSP page using a link. Basically the link is controlled by a serlvet but the validation is in Javascript and looks something like this

<a href = "javascript:if (aFunction() == true) <%JSP to take to to page%>".

Unfortunately it doesn't work - the Javascript function is evaluated but the JSP is ignored, I guess because it should have been evaluated on the server before the Javascript runs. I've tried a few variations like putting the JSP in the function but it still doesn't work. Is there anyway around this, like using the onClick event or something?

Thanks,

Matt

This is one way:

<a href="<%JSP LINK%>" onclick="return aFunction()">BLAH BLAH</a>
