<form method="post" name="form">
<script language="javascript">
function total()
{
var total
total=parseFloat(document.all.长度.value) + parseFloat(document.all.单价.value);
document.all.价格.value=total;
}
</script>
<%
dim i
for i=1 to 10 %>
<input type="text" name="长度<%=i%>" size="8">
<input type="text" name="单价<%=i%>" size="8">
<input type="text" name="价格<%=i%>" size="8" onClick="total();"><br>
<%next%>
</form>
大概是这样了!~~
參考答案:这样试下呢，循环出来的几个框名字都用相同的，然后用数组来获取
<form method="post" name="form">
<script language="javascript">
function total()
{
if(document.all.长度.length)
{
for(i=0;i<document.all.长度.length;i++)
{
var total;
total=parseFloat(document.all.长度[i].value) + parseFloat(document.all.单价[i].value);
document.all.价格[i].value=total;
}
}
else
{
var total;
total=parseFloat(document.all.长度.value) + parseFloat(document.all.单价.value);
document.all.价格.value=total;
}
}
</script>
<%
dim i
for i=1 to 10 %>
<input type="text" name="长度" size="8">
<input type="text" name="单价" size="8">
<input type="text" name="价格" size="8"><br>
<%next%>
<script>
total();
</script>
</form>
