Frustrated with curious TokenMgrErrors and ParseExceptions in your web forms? (I was) Not so good at regular expressions? (I'm not) See attached for a (simple) implementation of a regex-based javascript query validator. Currently, only wildcards (*), plus and minus (+, -), parentheses (round brackets) and field declarers (:) are validated for. The reason's coz they're the most commonly used (IMHO) and I'm lazy. If you do add to it/fix any bugs, I'd appreciate if you could drop me a buzz so I can update it, or post it to the list for everyone to use. Note: I've found that in IE at least, hitting the enter button with a text field in focus irritatingly submits the form without giving me a chance to validate the query. I've had to disable the "Enter" key for the form fields. Email me offline if you need help with this.
