Re: Complex Form Validation

2003-11-18 Thread Nicholas L Mohler 





George,

I have done something similar to this.  I haven't looked at browser
compatability yet(we're currently using this with ie6), but the concept
that I use is that I look at the parents of the form field, trying to find
out if the element is hidden.  If I find that a parent that is hidden, then
I take appropriate action.

My javascript loop looks like this:

var hiddenParent = false;
for(parent=formField.parentElement; parent != null  hiddenParent ==
false; parent = parent.parentElement) {
 if(parent.currentStyle.display == none) {
  hiddenParent = true;
 }
}

if(hiddenParent) {
 etc, etc
}

Hope this helps a little.  If there are better ways to do this, I'd love to
get the feedback :-)
Nick

We are trying to perform some complex form validaion with the new Validator
plugin.  Here is what we are trying to do:

1 -- validate a form field based on other form fields
2 -- validate a form field based on div style settings

I know that I could solve the first problem with the old validation
architecture, but is there a way to do that through the validator.xml?  I'm
not sure about the second problem.  The code looks something like this

div id=myDiv style=display: none
//my form element here
/div

So is it possible to only validate the form element above only if the
enclosing div display is block?  I've looked, but couldn't find anything
explaining how to go about this.  Any ideas?

Thanks in advance,

George

Nick,

Thanks for your response.  I'm doing something similar with javascript.  What would be 
better is if we could validate the form serverside with the validation framework...  I 
think we would have to write a custom validator that somehow would get the div parent 
of the form field and check that before checking the actual field.

Thanks,

George

George,
You can't do the validation server-side as you proposed because the browser
only sends HTML form elements. It will not send any information regarding
the div tag. You would have to have a hidden form variable and use
JavaScript to populate it with any values of interest when the form is
submitted. 

Regards,

Richard
