[Javascript] Checking Radio Boxes with a loop

[David Stoltz]

Thanks all! I see there are many solutions! This is the one I went with:

		for(i=1;i<34;i++)
		eval("form1.question" + i + "[0].checked=true");

Again, thanks for all the quick responses!

Hi,

Try:

for (i = 1; i < 33; i++) {
    form1['question' + i][0].checked = true;
}

(I haven't tested this, but it should work.)

Regards,

Nick.
