           Summary: Single line JavaScript comment prevents HTML button
                    click handler execution
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore JavaScript
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mihnea at adobe.com

Hello,

If i add a single line JavaScript comment at the end of a HTML button handler
for click, the handler is not executed.

I was able to reproduce the problem using the following sample:
<HTML>
<BODY> 
<input type="button" id="myButtonTest" value="Works" onClick="alert('OnClick
Button1');" />
<input type="button" id="myButtonTest1" value="Doesn'tWork"
onClick="alert('OnClick Button2');//;" />
</BODY>
</HTML>

While clicking on button "Works" displays the alert, clicking on the button
"Doesn'tWork" does not bring up the alert message. Removing the //; comment or
replacing it with /**/ solves the problem.

I was able to reproduce the problem using:
-> WebKit 41357 running on Mac Leopard
-> Safari 4 both on Mac Leopard/Win
-> Google Chrome on Win

FF3/Opera 9.63 do not have the problem in both Mac/Win environments.

Regards,
Mihnea
