By the way, it is an old post. Today, you can simple do it by using jQuery.

The script I wrote is very old. You can simply do this using jQuery now, with a single line code

Hi,

This can be hugely optimized for forms with a lot of checkboxes if you get inputs.length before the loop so the input.length won’t be calculated in every iteration of the loop.

var inputsLength = inputs.length;
for (var i = 0; i < inputsLength; i++)

This code can be cut down slightly by doing the following:

function checkAll(){
var t = document.getElementsByTagName(‘input’);
for(var i in t)
if(t[i].type==’checkbox’)
t[i].checked=true;
}
