JavaScript问题doPostBack

Question

I am having some problems.

My page is failing in this javascript code (the second line):

function __doPostBack(eventTarget, eventArgument) {
    if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
        theForm.__EVENTTARGET.value = eventTarget;
        theForm.__EVENTARGUMENT.value = eventArgument;
        theForm.submit();
    }

It is telling me:

'theForm.onsubmit' is null or not an object.

Any ideas please?

Thanks ! C
