If you plan to update, please make sure you also update the Validation Plugin to version 1.5.1, which is compatible with both versions 1.2.6 and 1.3. The main updates include:
1. Use the validHandler parameter to replace the useless form events that must be bound before. For the specific demo, you can visit marketo (http://jquery.bassistance.de/validate/demo/marketo/ )
2. Add Tiny MCE, sample demo (http://jquery.bassistance.de/validate/demo/tinymce)
3. Add Ukrainian localization
4. Fix length validation with balanced values
Generally, you can get support in the following ways:
1. Submit your question to the jQuery discussion list
2. Submit the bugs and new features you find to jQuery bug tracker
Enjoy the fun brought by jQuery!
