Hi,

I'm trying to validate a group of checkboxes(for as many records as my query returns). can somebody help me with that please?

Thank you

Possibly... perhaps if you explained the criteria you wished to validate them against.

Hi,

I want to make sure they are all checked.

Thank you!

Mary, perhaps if you showed some of your code or what you've attempted so far it would be easier to point you in the right direction. Here's an incredibly bare bones example:

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">

function validate() {
   var a = document.getElementsByTagName("input");
   for (i = 0; i < a.length; i++) {
      if (a[i].type == "checkbox") {
         if (!a[i].checked) {
            alert("one or more of the checkboxes are unchecked");
            return false;
         }
      }
   }
   alert("all the checkboxes are checked");
}

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

<input type="checkbox" />
<input type="checkbox" />
<input type="checkbox" />
<input type="checkbox" />
<input type="checkbox" />
<input type="checkbox" />
<input type="checkbox" />
<br />
<input type="button" value="check 'em" onclick="validate()" />

</body>
</html>

Thank you Kaht

I think what I was doing wrong was checking for the value of the checkbox and comparing it to null.

Thank you again,
