What am I overlooking? Totally stumped! var s = document.getElementById('field[12]');
var cust_cc_exp_month = s.options[s.selectedIndex].value;
// This displays the correct Value -- which is "0" for item #0 = "Please select..."
alert("Month: " + cust_cc_exp_month.toString());
if (cust_cc_exp_month == "0") {
// This code never executes!
}
Here is the HTML portion:
<select id="field[12]" name="field[12]">
<option value="0">MONTH</option>
<option value="1" <?php if ($field[12] == "1") echo "SELECTED" ?>>January</option>
<option value="2" <?php if ($field[12] == "2") echo "SELECTED" ?>>February</option>
<option value="3" <?php if ($field[12] == "3") echo "SELECTED" ?>>March</option>
</select>I've tried using cust_cc_exp_month.toString(), and I've tried == 0 instead of == "0".
Nothing seems to work. To me, it defies all logic! There has to be something I'm overlooking.
Thanks for any help you can provide --
Matthew

Are you putting string values into field[12] ?

I just tried this test:
After the window loads, alert('ok'); is executed as expected. I tested in FF2.0 and IE6,7.
I don't see how you could be having the problem you're having unless you have a JavaScript error somewhere thats preventing full execution of the JS.
a conditional such as:
is equivalent to:
or
since type's are not being evaluated.
If you had
then the type would matter and an Integer 0 would be differentiated from the string '0' or the boolean false.
