onsubmit help

[thefortrees]

Hi all -

 

I am having a problem with the onsubmit event handler. Onsubmit, I call the function below. The problems I am having are:

1) If the confirm dialog is used, the redirect does not occur.

2) If the alert dialog is used, even though the function returns false after the dialog, the form still submits! I have been wrestling with this for a while now.

Thanks for your help.

 

function enterInfo() {
		if (validate() == 1) { 
			if (confirm("Would you like to enter our monthly prize drawing? (OK = Yes, Cancel = No)")) {
				window.location = "enter_info.php";
				return true;
			}
			else {
				window.location = "thank_you.php";
				return true;
			}
		}

		else if (validate() == -1) { 
			alert('Please respond to all questions.'); 
			return false;
		}
	}

How you call your enterInfo() function?

 

You should use this:

<form onsubmit="return enterInfo();">

 

So if your function return false, the form will not submit, else it does.

I don't think that will help. Where is the onsubmit event going to return to? There's no caller on the call stack...

 

I would do it in PHP. Make the file your JS code is in have some thing like:

 

<?php
if(one of the POST data == "") {// They didn't respond to a question...
  echo "You didn't respond to all of the questions. Click the back button in your browser and finish filling out the form.";
  exit;
} else {
  // Process the POST data from the form here, then
  echo "Would you like to enter our monthly prize drawing? ";
  echo "<a href='enter_info.php'>Yes</a> <a href='thank_you.php'>No</a>
}
?>

 

This also has the advantage of browsers without JS can still use it.
