Using variables in [document.VARIABLE.VARIABLE.checked], etc...

[Sugapablo]

I would like to use variables in...

for(q = 0; q < i; q++) {
if(document.var Array1[q].varArray2[q].checked == TRUE) {
alert("YES");
}
else {
alert("NO");
}
}

What's the proper syntax?

Assuming that the variables represent the name of a form and
the name of an element in that form, respectively:

if(document.for ms[varArray1[q]].elements[varArray2[q]].checked)

Note that there's no need to compare a boolean to true.
Its own value will always be the value of the comparison.

This loop will only check the first element in the first form, the second in
the second and the third in the third. If you want to check all items in all
forms, you need to nest two loops.

ISTM that he's not comparing it to true, but to TRUE, which is a
variable, possibly defined. In principle, it could be defined as
TRUE = !!Math.round(Ma th.random())

It is == true that he should not be using, not == TRUE .
