From W3C: http://www.w3schools.com/html5/html5_ref_eventattributes.asp onsubmit is an allowed form event. The error I get is below: Attribute form not allowed on element form at this point. ...method="post" target="hidden_iframe" onsubmit="submitted=true;"> Attributes for element form: Global attributes accept-charset action autocomplete enctype method name novalidate Brad 55720 1 ville.skytta 2011-08-23 19:59:44 +0000 (In reply to comment #0) > From W3C: > http://www.w3schools.com/[...] Please note that W3Schools != W3C. > onsubmit is an allowed form event. [...] > Attribute form not allowed on element form at this point. The error message says that attribute "form" is not allowed on element "form", I don't see anything about onsubmit in it. A URL to a document or a complete HTML5 fragment with which the problem can be reproduced would be helpful. 58896 2 mike 2011-10-25 08:35:13 +0000 see comment #1
