<tr><td><input type="checkbox" name=opt onClick="if(this.checked) qty1.focus()">

下次如有问题可以请教你吗？

如过是这样,还有什么要调整的吗?

<html>
<head>
<script>

function calc(n){
x = document.purchase;
if ((x.opt[n - 1].checked == true) && (n = 1)) {
   x.total1.value = x.qty1.value * x.price1.value;
   }
else
   { x.total1.value = 0;
   }

  if ((x.opt[n - 1].checked == true) && (n = 2)) {
   x.total2.value = x.qty2.value * x.price2.value;
}
  if ((x.opt[n - 1].checked == true) && (n = 3)) {
x.total3.value = x.qty3.value * x.price3.value;
   }
  if ((x.opt[n - 1].checked == true) &&(n = 4)) {
   x.total4.value = x.qty4.value * x.price4.value;
   }
}

function gTotal(){
x = document.purchase;
x.gtotal.value = eval(x.total1.value) +
               eval(x.total2.value) +
               eval(x.total3.value) +

你的Code怪怪的，HTML格式也有点松散。帮你改了一改让你参考一下:

<html>
<head>
<script language="javascript">
function calc(n){
var x = document.purchase;
if ((x.opt[n - 1].checked == true) && (n == 1)) {
x.total1.value = x.qty1.value * x.price1.value;
}
if ((x.opt[n - 1].checked == true) && (n == 2)) {
x.total2.value = x.qty2.value * x.price2.value;
}
if ((x.opt[n - 1].checked == true) && (n == 3)) {
x.total3.value = x.qty3.value * x.price3.value;
}
if ((x.opt[n - 1].checked == true) &&(n == 4)) {
x.total4.value = x.qty4.value * x.price4.value;
}
}
function gTotal(){
var x = document.purchase;
var total=0,subtotal;
for(var i=1;i<=4;i++){

x.gtotal.value = total;

function elementSelect(name,selectElement){
