Confirmed Submit does not take NO as an answer 2

cumap · Nov 7, 2007

Hi all,

I'm having this cofirmed function, but it run as YES anyway no matter user clicked CANCEL or closed alert window.

Code:

function confirmSubmit()
	{
		if (confirm("This action can not be undone. Are you sure you want to continue?"));
		{
			document.form3.action="update.asp";
			document.form3.submit();
		}
	}

Thanks.

I think I understand the problem...

I'm not totally sure here but it seems to me that if I remove the ";" at the end of the IF statement, the function will work then. Would someone confirm this for me please.

That is correct. If statements do not require a semi-colon. If you write your javascript such that your opening bracket is on the same line as your if statement, then this will look and become less confusing to you. Here's a quick example to illustrate the point:

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "[URL unfurl="true"]http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">[/URL]
<html xmlns="[URL unfurl="true"]http://www.w3.org/1999/xhtml">[/URL]
<head>
<title>test</title>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<script type="text/javascript">

window.onload = function () {
   if (false) {
      alert("check1");
   }
   if (false); {
      alert("check2");
   }
};

</script>
<style type="text/css"></style>
</head>
<body>
</body>
</html>

You are correct- the semi-colon at the end of the if statement serves as a line terminator. Therefore, regardless of the choice of the user, the script continues to execute the next statements underneath it, in this case, setting the action and submitting.

Thanks guys!!! so the semicolon is the line terminator that will terminate the if function. And I thought the semi-colon serves as "finish" on a line and start a new line. pitty me!!!
