Enhancement: Client side validation

Reported by Nicholas Blasgen | March 2nd, 2009 @ 12:46 AM

I couldn't find any way to add client side validation so I added an extension to cover the need. This is an early draft just to make my site work correctly, but in the future it should use triggerCallback() so that the transport is passed. In my version you can't do something like modify the value prior to sending it to the server--you can only either allow the form to submit or stop it. I would like to make it so that the validation could modify the string (such as stripping off a $ in a field expecting a float because it's meaninless), but at the same time I really like being passed more than a single argument to the function.

Using 1.8.2.

Diff (old version, new version):


if ('function' == typeof this.options['onSubmit']) {
  if (this.options['onSubmit'](this.element.id, value)) {
    return false;


errorClassName: 'inplaceeditor-error',


onSubmit: function(editorId, editorValue) {
          return true;            // return true on error

    I see now that 1.x.x is feature frozen. Please include something like this in v2. I haven't looked at v2 code, so I'm not sure what features it already supports.
