• Status: NEW
• Component: DOM

If submitting a form in onsubmit handler, the submitting may be failed!
Bug's source: open www.sina.com.cn, loginin free email.

Test case like this:

<script>
function chkLogin(){
	
   document.showLogin.submit(); // note
   document.showLogin.password.value = "";

   return false;
}
</script>
	
<form name="showLogin" method="post" action="test.php" onsubmit="return chkLogin();" target="_blank"> 
UserName:<input type="text" name="username" value="" /><br>
Password:<input name="password" type="password" /><br>
<input type="submit" value="Login" /><br>
</form>

After chkLogin is executed, the password is empty and HTMLFormElement executes real submiting action after dispatching sumbit event, so the submitting failed.

Hi,

I have checked this on the latest code, while choosing "Login" in the new window test.php will get loaded, and in the previous window Password field is empty, That is I think is intended behavior.


Please verify on latest and confirm..

Thanks
