Child Not (always) submitting while closing

vinayak · Oct 15, 2003

Hi,
I have a child window which submits a form, then closes. The problem is, sometimes form is not submitting at all. CONFIG: IE 5, WIN 2K, TOMCAT 3.0.

Child JSP:
........
........
<SCRIPT LANGUAGE="JavaScript" PURPOSE="Include" SRC="FeedBack.js"></SCRIPT>
<BODY ......... onload=" LoadFeedbackForm();">
<FORM name="FeedbackForm" method="post" action="" onsubmit="JavaScript:return SubmitFeedback();" >
....................................................
....................................................
<input type="Submit" name="Submit" value="Submit" TABINDEX="4" >
<INPUT TYPE="button" NAME="Close2" VALUE="Cancel" TABINDEX="6" onClick="self.close();">
</FORM>
</BODY>
........
........

FeedBack.js:
var submitFlag=false; // check for multiple submissions
function SubmitFeedback()
{
var ls_form=document.FeedbackForm;
if(submitFlag==false)
{
submitFlag=true;
ls_form.action = 'Feedback?ps_Action=Feedback';
//ls_form.submit(); //This is the point of submission
window.self.close();
return true;
}
else
return false;

}

I have a similar problem. I have read elsewhere that the form submission doesn't always complete before the window is closed. I tried using the setTimeout function but that didn't work. I ended up writing a function to delay the window closing for 3 seconds to allow sufficient time for form submittal.

function pause(numberMillis) {
var now = new Date();
var exitTime = now.getTime() + numberMillis;
while (true) {
now = new Date();
if (now.getTime() > exitTime)
return;
}
}

Then call this function after form submittal but before the window closing event. You may want to wrap it all in a confirm to warn the user there will be a delay.

if(confirm("Data will be submitted for update.\n" +
"This will take aproximately 3 seconds." +
"\nDo you wish to continue?&quot

) {
form.submit();
pause(3000);
window.close();
}else {
return false;
}

This isn't pretty, but it's the best solution I have found in my few weeks of writing Javascript.

If anyone has a better idea, I'm all ears.
