Opinions on Javascript obfuscators, anyone?

I'm just trying to get a feel of how many people actually use JavaScript obfuscators, and I'd also be interested in your opinion on what you think about it.

Thanks.

Gary, I was thinking of making a "fat client" where all form validations will be done within the page with JavaScript. The alternative is to allow PHP to validate the form, but that might take longer depending on the traffic on the website. Also, it occurred to me that someone can just copy the page and remove all validations and submit the form.

I figured obfuscating the JavaScript might help.

Js shouldn't be relied on for validation, yes you can validate the input before submitting to prevent unnecessary work at the server, but that is the only main reason (apart from giving tips to the user on how to fill in the form)

All validation should be done at the server side - never rely on the js to do the work, they don't need to remove the js, just disable js in the browser.

And obfuscation is irrelevant in this case.

Obfuscating doesn't help, spammers and hackers have code to automatically de-obfuscate it.  It only prevents consumers from reading it.  For validation, you should use javascript on the page to help the user fill out the form correctly.  But you should also validate and check the submissions with PHP on the 'action' page because the spammers and hackers will post directly to your page and bypass all of your javascript.  You should be doing Both.
