函数CalcDiscountedPrice（百分比支付）{
var i=1；
因为（i=1；i你有输入错误，你在打电话
onclick="CalculcateTotal();"
但你的功能是
function CalculateTotal() {
将onclick更改为
onclick="CalculateTotal();"
试试F-12。该浏览器中有一个调试器。下面修改的是您的javascript。注意，我已经取消了所有变量的资本化，因为这是一个糟糕的做法

对于（i=1；i该函数有什么问题？CalculateTotal
函数实际上没有做任何事情。它迭代将每个DOM元素放入DiscountedCell
变量中，但它从未对每个元素做任何事情。它也不会修改total
变量，也不会返回任何东西。你期望函数做什么？我同意这里的@RJM-很难理解不完整代码背后的意图。用几句话描述一下你想要完成什么。
