I posted this the other day. I don't know why people use "location". This is
how it should be done:
<a href="javascript:myFormFunction('/servlet/ServletName','formName')>text
or image</a>
Then in the head of the document (or js include) put a function something
like:
<script>
function myFormFunction(theAction, theForm) {
// custom cross platform function that gets an object..
// create your own or take Dreamweaver's - MM_findObj or something like
that
myFormObj = getObject(theForm) ;
// set the action
myFormObj.action = theAction;
myForm.submit();
}
</script>
