dyamic validation for a field

Hi,

I want a field to be shown/hidden and validated depending on a value of a certain dropdown.
I am able to hide/show the field but the validation would not work.

I have added this code in my load JS event. Have i missed something?

window.addEvent('domready', function() {
    $('product_interest').addEvent('change', function() {
        if($('product_interest').value == 'Loans'){
        	$('loanspacer').setStyle('display', '');
        	$('loanrow').setStyle('display', '');
            $('comments').addClass("validate['required']");
            formCheck.register($('comments'));
		}
    });
});

formCheck.register($('comments'));

is working since when i replace it with a non existing field it will generate a javascript error.

Hi elvinjoe ,

That looks OK to me. Please take a Form Backup using the icon in the Forms Manager and post it here (as a zipped file) or PM or email it to me and I'll take a closer look.

Hi elvinjoe,

This works OK on my test site. The only problem is that it comes last in the validation sequence. You can fix this with a second parameter.

formCheck.register($('comments'), 1);

I also added code to handle a change of the drop-down and the page reloading:

window.addEvent('domready', function() {
  $('product_interest').addEvent('change', function() {
    if ( $('product_interest').value == 'Loans' ) {
      $('loanspacer').setStyle('display', 'table-row');
      $('loanrow').setStyle('display', 'table-row');
      $('comments').addClass("validate['required']");
      formCheck.register($('comments'), 1);
    } else {
      $('comments').removeClass("validate['required']");
      formCheck.dispose($('comments'));
      $('loanspacer').setStyle('display', 'none');
      $('loanrow').setStyle('display', 'none');
    }
  });
});
window.addEvent('load', function() {
  if ( $('product_interest').value == 'Loans' ) {
    $('loanspacer').setStyle('display', 'table-row');
    $('loanrow').setStyle('display', 'table-row');
    $('comments').addClass("validate['required']");
    formCheck.register($('comments'), 1);
  }
});

Wonder if you can help me with similar issue.

on the addEvent, I keep getting the VARNAME is null.

Tried $('#radio5').value as well as $('radio5').value but keep getting "radio5 is null"

Mootools is loaded.

Hi jhdesign ,

Check that you have an input with the id='radio5' set??

Bob

Bob yes it here, here's the code:

Yes
  <input type="radio" name="radio5" id="radio50" class="radio" title="" value="Yes"/>
  
  No
  <input type="radio" name="radio5" id="radio51" class="radio" title="" value="No"/>

I have some jQuery on this page, I wonder if it is causing a conflict.

Your ids are "radio50" and "radio51", so "radio5" will be null for sure.

Regards,
Max
