Check box validation

[ishlux]

Hi all,

Can i know how to do the checkbox validation........
i used the code below but its not validating.....

var val;	
	for(i=0;i<3;i++)
	{
		if(form2.elements['contype[]'][i].checked)
			val=1;
	}
	if(val==0)
	{
		alert("Select type of your Contract")
		return false;
	}

if ( document.Form2.elements.contype.checked == false )
    {
        alert ( "Please Select type of your contract." );
        valid = false;
    }

Try this:

for(var i=0; i < d.c.length; i++){
			if(d.c[i].checked) {
				total +=d.c[i].value + "\n";
				d.check_compare.value=d.check_compare.value+d.c[i].value+',';
			}
		}
		if(d.check_compare.value=="") {
		 alert("Please select atleast one check Box");
		 return false;
		}

Hey use this code where your checkbox validtion goes:

<script language="javascript">
function check()
{
	var d=document.checkoutform;
	if(d.confirm1.checked==false) {alert("Please confirm your details are correct!!");
	return false;
	}
  	else
	{return true;}
		
}
function trimstr(str) {
	str= this != window? this : str;
	return str.replace(/^\s+/g, '').replace(/\s+$/g, '');
}
                              </script>

I think its working...
