Need to loop through checkboxes

[Greg Griffiths]

do something like

for (i=0;i<document.myForm.length;i++)
{
if (document.myForm.type=="checkbox")
{
alert("Checkbox");
}
}

I have a form with an unknown number of checkboxes (the page is generated
by a server-side script). I need to loop through those checkboxes, test
whether the name of each checkbox starts with a known string and, if it
does, clear that checkbox.

I've tried just about everything that I can think of, but to no avail.

Can someone tell me how to loop through the checkboxes of a form?

TIA,
