XHTML error: Attribute 'for' is not a valid attribute of element 'script'.

[Tom Chi]

Hi,

I am porting an ASP.NET Javascript/C# application from .NET framework 1.x (everything works there) to 2.0 on Windows Server 2003 SP1, and experieced problem (null reference) while trying to raise a custom event ("DisplayMessag eRequested"). The web page exposes the event in a user control hosted in Internet Explorer 6.0. The Javascript event handler uses Microsoft specific 'for and 'event' syntax as shown below:

<script type="text/javascript"
for="wkflCtl"
event="DisplayM essageRequested "
language="javas cript">
displayMessageD ialog(wkflCtl.m essage1,
wkflCtl.selecte dLots,
wkflCtl.selecte dJobID);
</script>

where wkflCtl is the object id of the user control applet loaded into the web page.

VS.2005 gives the following errors for both 'for' and 'event' attibutes:

Error 69 Validation (XHTML 1.0 Transitional): Attribute 'for' is not a valid attribute of element 'script'.

Two questions:
1) I have <xhtmlConforman ce mode="Legacy" /> under system.web in my web.config. Could I safety ignore the above error? or this error causes the event handler displayMessageD ialog not registered (and thus the null reference error while trying to raise the event)?
2) I tried to use attachEvent (in OnLoad) but has two questions:
a) it only accepts standard event handler
b) the user control is not yet loaded when OnLoad is executed.

Thanks for your help.

Tom
