[RESOLVED] Help with validation script

[mikawhat]

I'm using the following code to make sure all the fields of the form sent are not empty:

function validate_required(field,alerttxt)
{
with (field)
{
if (value==null||value=="")
  {alert(alerttxt);return false}
else {return true}
}
}
function validate_form(thisform)
{

with (thisform)
{
if (validate_required(fname,"Enter your name!")==false)
  {fname.focus();return false}
}
with (thisform)
{
if (validate_required(lname,"Enter your surname!")==false)
  {lname.focus();return false}
}

}

I have a group of radio buttons that i also need to validate. Can anybody help me to include the validation for radio button in this script?

STFU! If you don't wanna help just don't reply!

Did you even look at the search? The first result is a tutorial about validating radio buttons. I was sincerely trying to help, I am not going to spoon-feed you though.

i want something like:
with (thisform)
{
if (validate_required(fname,"Enter your name!")==false)
{fname.focus();return false}
}

and i'm not that good with javascript to understand how to run a new function within the current one..

I'm afraid nothing like that can be used to validate a group of radio buttons. They must be iterated through with a loop.

This works:
var i=0,rad=document.getElementsByName('radioname'),r,q=false;
while(r=rad[i++]){
if(r.checked){q=true;break}
}
if(!q){
alert('Please, check a radio button!');return false;
}
