I mean, a similar function supported by webkit –powerboy Apr 9 '10 at 4:05 1 You mean there are browsers other than IE and Mozilla??? Dang! I need to get out more :) –DVK Apr 9 '10 at 4:10 Actually it'll be supported (hopefully soon) in WebKit - see phwinfo.com/forum/comp-lang-javascript/… –DVK Apr 9 '10 at 4:12 yep! But I got another problem. Seems that onerror only support those 3 parameters. There is no way to catch an error of a specific name. –powerboy Apr 9 '10 at 4:30 | show 1 more comment 4 Answers 4 active oldest votes up vote 27 down vote accepted Yes, that is the correct way.

is moved to the correct category. Anyway. I am pretty new with web design, and I am https://www.sitepoint.com/community/t/how-to-make-an-error-popup-message-after-submitting-a-form/15193 currently learning about the subject on high school. We work on software that is a bit outdated (Adobe CS3), but I still like doing it. As for web design, we use WAMP server, Dreamweaver CS3, MySQL Query Browser and PHP. I do, however, know little to nothing about coding in PHP, I just kind of know what it's for. I know how to make javascript popup a functioning web page, how to create databases and connect them to the web page, and how to show these databases through a dynamic web page, but little else. So the thing I am trying to do now is that after using an "Record Insertion Form Wizard" in Dreamweaver CS3 (to which I've already made a database, a query and so on), I javascript popup error want two different popup messages to come after clicking "submit form", both one confirming that the entire process was successful, and one saying that the user entered invalid information. I already know how to do the former, by going under Tag , behaviors, clicking the plus-sign, clicking popup message and then just writing the message and hitting "OK". But how do I make a seperate one for if the submission failed? And is it possible if this box automatically tells the user exactly what went wrong? boatmark 2012-04-27 01:50:40 UTC #2 hmm, I think you should use javascript. attach onsubmit event, then do evaluation of the form content something like that: Untitled Document
