seeing if checkboxes are checked

[heaps21]

I am having problems with this:

var day_time = (dayOfWeek+'.'+t);
 if(!document.myForm.day_time.checked) {alert("ARGH");}

in that it doesnt substitite the value for day_time, rather just uses the string 'day_time'.

(day_time is of the form "monday.am" which is also the NAME of a particular checkbox in my form.

Can anyone help me please! Thanks.

document.getElementById(day_time)

should work - make sure your checkbox's ID attribute is correctly entered, of course.

Or you could just use eval("document.myForm."+day_time+".checked")

but that's bad, apparently.

sorry, day_time is ID of the checkbox, not the name DOH! does that mean there are any other ways to do it? I tried the ."+day_time+". like you said but i keep getting "unexpected identifier" errors .

Thanks again!

Sorry, getting a little confused. Does document.getElementById(day_time) not work then?

[heaps21]

yey!

sorry, my mistake - i assumed that coz i said it was the name rather than the id, it wouldnt work - just tried it though and it works fine - thank you!! thats my stressful afternoon over with!!

var day_time = (dayOfWeek+'.'+t);
if(!document.myForm.elements[day_time].checked) {
    alert("ARGH");
}
