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

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');
}
}

Try this . . .

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 allChecked = 0;
	for (var i = 0; i < node_list.length; i++){
		var node = node_list[i];
		if (node.getAttribute('type') == 'checkbox'){
			if(!node_list[i].checked)
				return(false);
		}
	}
}

I appreciate your quick response and help. thankx
But this code is not working means it is not taking any action on clicking 'submit' button.....

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?

Hi,
I have tested the code sent by xerxes333 on FF,IE+7 and Opera also, but it's not working.

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.
