Hi,
Here is the code for checkbox validation
I think there is a problem with 'return' statements.
As validation for textbox works fine but for checkbox it won't.
After clicking all checkboxes it shows alert message alert(Select user)....Please help me...
Thank you smile.gif

function Vailidate(form)
{
'validate textbox
var total = 0;
if (form.taskdescr.value == '')
{
alert('Task Description is required.');
return (false);
}
'validate chkbox
var node_list = document.getElementsByTagName('input');
var chkboxes = [];
for (var i = 0; i < node_list.length; i++)
{
var node = node_list[i];
if (node.getAttribute('type') == 'checkbox')
{
chkboxes.push(node);
}
}
if (!chkboxes.checked)
{
alert('select user');
return false;
}
else
{
alert('selected');
}
}

Post a link to the rest of your code as the error may be elsewhere.
BTW, have you looked at the error console in FF.
What browser are you using?

The code works just fine if you call it properly. In your FORM tag you need to add this attribute
onSubmit="return Validate(document.getElementById('myForm'))"
obviously substituting the document.getElementById('myForm') for your form node.
