Call me old fashioned. I started using JavaScript in the 90s before jQuery was even an idea. Sure, I can troubleshoot jQuery, and it is used a lot in Drupal, but my first impulse is to write regular JavaScript, which still works too. I think jQuery is the best JS framework, I've worked with prototype.js, mootools etc. too.

But when I wanted to hide an obscure and possibly meaningless warning message on the user account edit page (so that new members would not get freaked and think they did something wrong) I struggled.

First I hacked the user.module and although I removed the warning I also gave everybody admin access, including people who are not even logged in - not a good idea.

So I used CSS to hide the warning messages on "body-page.user" which seemed to do the trick.

Then my client told me he was having trouble creating new accounts, and I realized that I hid ALL user module warnings including "User name xxxx already exists" so I was back with the ugly warning.

Finally, I decided to hide just the warning with the text in question. Sure, I could have done it with classic JavaScript, indexing through all the div elements and looking for the matching innerHTML text and hiding the div. I guess that would have been about 8 lines of code.

I decided to figger out the best jQuery method. I came up with one line of jQuery code to add to my theme template that did the trick:

<script type="text/javascript">$("div.messages:contains('Illegal offset type in isset or empty')").hide();</script>

(note: the .messages selector is crucial; without it, all divs that are parents of the warning are also hidden, effectively hiding the entire page!)

thanks, jQuery...

now about that PHP warning...
