View Full Version : Could really do with a hand

12-09-2006, 10:25 PM

I've really tried to work this out but I can't.. I've read up on variable functions but can't get the link right.

I place a variable in the beginning of the JS such as:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

<!-- Begin

var mx="5.73";

function doMath(s) {
var form = document.getElementsByName(s)[0];
var one = parseFloat(form.con1.value);
var two = parseFloat(form.cable.value);
var three = parseFloat(form.length.value);
var four = parseFloat(form.con2.value);
var five = 0.0;
if (form.con3) {
five = parseFloat(form.con3.value);
var prod = (two * three) + one + four + five;


function custRound(x,places) {
return (Math.round(x*Math.pow(10,places)))/Math.pow(10,places)

// End -->

But I can't get it to control the HTML. What I have in there is:

<select name="con1">
<option value="createElement('mx')"selected>Male XLR</option>
<option value="6.26">Female XLR</option>
<option value="6.83">Stereo Jack (TRS)</option>
<option value="5.70">Mono Jack</option>
<option value="4.05">Phono (RCA)</option>
<option value="4.05">Minijack</option>

Please give me a clue to what I'm doing wrong. I tried to figure it out but have failed..

Thanks in advance

Did you look at my response to your last post about this question?
