How to add javascript actions (like "onkeyup") to FormFields?

Howdy

I've been working on a form that uses validation from our internal systems. To get it running I statically coded it and now I'd like to build it using the SS Form object.

There's two things I'm still trying to work out how to do:

  • A few of the TextFields and NumericFields require a "onkeyup" action which trigger the validation javascript. In HTML this would look like
    onkeyup="validateValuationNumber(this.value)"
    but I'm not sure what to add to this entry
    new TextField('ValuationNumber', 'Valuation Number', '' ),

  • I want to be able to place an empty DIV between two of the formfields which I can populate with dynamic information.

I'm guessing that these are both possible but after wading about the documentation and forums I still can't work out how I'm supposed to do it.

Any suggestions would be greatly appreciated.

Cheers

The form field API doesn't support adding events. I recommend you use jQuery to add event handlers to your form eg http://api.jquery.com/keyup/

Thanks Will - adding this works well:

<script name="javascript">
$('#Form_PaymentForm_ValuationNumber').keyup(function(validateValuationNumber) {
...

I also want to place an empty div between two of the formfields I can use for the custom validation. I know I can use a Read Only field to place a span but this will require DHTML after the load to make it invisible. Is there a tidier way?

document.appendElement to add an empty div then via javascript. You could also try using the RightTitle value. I think it puts the right title in a div (which then you add another div inside of).

To append the a new div called "valuationValidation" after the div "ValuationNumber" I used the following code:

jQuery('#ValuationNumber').after($('#valuationValidation').append('<div>'));

I ended up using the "jQuery" prefix instead of "$" as their seemed to be a conflict (with Prototype?)
