在以下代码中找不到计算错误 [英] Whats wrong in the following code for finding the calculation

问题描述

<script>
var f, quantity, rate, customertotal, salertotal, totalshare;
function calc (f)
{
    quantity=parseInt(f.quantity.value);
    rate=parseInt(f.rate.value);
    customertotal=(quantity*rate);
    salertotal=(customertotal*.80);
    totalshare=(customertotal*.20);
    f.customertotal.value=customertotal;
    f.salertotal.value=salertotal;
    f.totalshare.value=totalshare;
}
</script>

推荐答案

请参阅我对该问题的评论。它没有多大意义。



然而，无论你想达到什么目标，至少有一个错误的东西：第一行。你不应该在函数之外声明任何东西。



（另外，紧跟''=''之后的所有括号都是多余的，但这不是错误。）



我建议什么？也许，尝试获得一些关于编程的基本知识，而不是专门的JavaScript，阅读有关编程的一些信息。现在，看起来你似乎没有任何线索。

Please see my comment to the question. It does not really make sense.

However, there is at least one wrong thing, no matter what you wanted to achieve: the very first line. You should not declare anything outside of the function.

(Also, all brackets immediately following ''='' are totally redundant, but this is not a bug.)

What I would advise? Maybe, try to get some basic knowledge about programming, not specifically JavaScript, read about programming a bit. Right now, it looks like you have no clue.
