Javascript form validation

I know nothing (very little) about Javascript.

I have four text boxes I want to make sure that at least one of them has input before they can submit a form. Any ideas?

Thanks!

Mike

if ((textbox1.value == "") && (textbox2.value == "") && (textbox3.value == "") && (textbox3.value == "")) {
  // hark, there is not user input!
}

'I'm not too good with making things cross browser (sorry), but this will give you a start.
