OnSubmit event triggered before wf instantiation?

How do I associate a JavaScript event when submitting the form within iwwft_instantiator.cgi? I see plainly where to put the JavaScript but do not know where to actually CALL the event, as there is no <form> tag in the .wft file.

This is a major hack, but, assuming you don't get a better response ...

You could use one of the places where you're allowed to specify raw HTML to include some JavaScript&colon;

document.forms[0].onSubmit = referenceToOnSubmitHandler;

This makes the assumption that the data collection form on the WFT instantiation page is the only (or, at least first) form defined on that page.

Didn't work... to test it out, I did the following initialy:

document.forms[0].onSubmit = alert('hi');

and the alert was displayed immediately when the page loaded and not again when the form was submitted.

That's because you've got the wrong syntax. You've assigned the return code from alert to the onSumit handler. Had you done something like this:

function testSubmit() {
    alert("Hi!");
    return true;
}

document.forms[0].onSubmit = testSubmit;

I suspect it would have worked better. Notice the lack of any paren after testSubmit

Nope, I did exactly that and still no dice

It did not alert immediately upon opening, but it didn't do it when the form submitted, either.

OK. This made me mad, so I did some digging.

I finally got it to work the way I think it should, at least on a small test HTML page. Here are the caveats:

1. You have to assign your function name to document.forms[0].onsubmit. It appears to be case sensitive.
2. You can't assign this until the form has been defined. That means that the assignment has to come after the close form tag

The first is easy to take care of. The second might present a bit of a problem, since you don't have that much control over where things get loaded on the page. I have to admit that I don't remember much about how much control is available. If you can set attributes of the body tag, then you could put an "onload" attribute which will handle #2

I'll do that --

I actually don't have control over the body tag (at least, not that I know of), but I'll take your suggestions and will follow-up.

CGI_info(html_body_options => "onLoad='doThisOnLoad();' ");

Cool - that should be the missing piece.

I really should have known that - I just never spent much time with the "window dressing" aspects of the WFT instantiation form.

Sorry, but where is that called from? In other words, at which point in the wft, or does it even matter?

It goes pretty much anywhere inside of the <template_script> block

I am having the same issue in 6.5. The submit button is a hyperlink instead of a form button. Therefore, it does not trigger the OnSubmit() event.

How do I intercept the onsubmit() event in 6.5? Do I have to modify the iwwft_instantiation.cfg?

Thanks,

The simplest way to do what you want is (and always was, regardless of the version) not to
intercept "onSubmit" event but rather piggy-back it. Like that

my $javascript = <<"JAVASCRIPT";
<script>
function redirect_submission() {
   document.forms.iwwft_instantiator.action = "javascript&colon;custom_submit()";
}
function custom_submit() {
   alert("Your Pre-Submit Code here");
   // Fork here if WF instantiation is conditional

   // Restore original action and instantiate WF if needed
   document.forms.iwwft_instantiator.action = "/iw-bin/iw_cgi_wrapper.cgi/iwwft_instantiator.cgi";
   document.forms.iwwft_instantiator.submit();
}
</script>
JAVASCRIPT

CGI_info(
   html_body_options => "onLoad='redirect_submission()'",
   pre_tagtable_html => $javascript,
...
);

TAG_info(
...
);

That's a GREAT idea. Why didn't I think of that? Smiley Tongue

Thanks!!
