Stopping a form from submitting with VBSCript

**warker** · Mar 18th, 2002, 02:00 PM

I am trying to run a Validation function that is called when the submit button is clicked. The function checks the defined restrictions on the form, and if there is an error found, sets the status variable to 1. If there are not errors, the Status variable stays a 0. this is the next if statement I have:

IF Status = "0" THEN
document.form.submit()
ELSE
return false
END IF

the return false should stop the form from submitting. This is a JavaScript function, but I thought I was the same in VBScript, but unfortunately, the form still dispalys the errors, but also submits. Does anyone know how to keep a form from not submitting?

First of all, is the button's type 'submit' or 'button'? If it is of type submit, I doubt that your form validation is even working. You should have the button's type be 'button' and call the JavaScript function from the button's OnClick event.

Also your if statement is incorrect in javascript. Another thing to consider is what type of value has been passed to and stored in Status? You are doing a string comparison, if you passed a number to the variable, this would also cause your if ... then not to work properly.

Code:

if (Status=="0")
{
     document.form.submit() ;
     return true;
}
else
{
     return false;

No, my validation if statements are working fine. I receive every message when I should. I was using the onclick function and the problem was that when you clicked the enter key, the form was submitting without hitting the button hense, no validation. I had to use the onsubmit. and you are right, my if statements are not Javascript, but VBScript. I would like to stay with VBScript so all I am asking is if someone knows the correct return false statement in VBScript. Thanks though.

Hi Steve,
You shouldnt use vbscript on client side, but since you are adament here is how you can validate a form using VBScript.

Hope this helps

VB Code:

<HTML>
<HEAD>
<TITLE></TITLE>
<script language=vbscript>
function validate()
    if test.text1.value="" then
        msgbox "Please enter a value"
        Window.event.returnValue = false
    end if
end function
</script>
</HEAD>
 
<Form name=test onsubmit="validate()">
 
<input type=text name=text1>
<input type=submit>
 
</BODY>
</HTML>
