我正在尝试为我的网站制作简单的产品结帐系统.我正在使用paypal默认结帐系统.它工作正常,但我也需要优惠券代码设施.我从未在paypal中看到任何选项以获取优惠券代码.这就是为什么我试图通过 jquery创建它.

我成功了,但它仅适用于一种产品.当我在页面中添加更多产品时,这是行不通的.我可以理解它关于类和id的问题,但我仍然不知道如何做到这一点.也尝试折扣作为％明智当前我的代码只工作硬编码价格.

你们会检查我的代码,看看我的错误在哪里,或者如何做到.或者,如果还有其他方法可做

解决方法

如果您想动态计算多个产品的折扣,那么将所有产品的价格合并,然后在获得总额后应用优惠券折扣

所以,你的代码应该是这样的……

function calcPrice(){
var v = parseInt(document.getElementById("val").value);
var q = parseInt(document.getElementById("quantity").value);
if ((isNaN(q)) || (q == null) || (q <0)) {
alert ("You must enter a positive number");
document.getElementById("quantity").value = "";
return false;
}
var p = calcTotal(v,q);
alert("Total Price = " + p);
}

function calcTotal(v,q) {
var discount = 0;
if (q>=1) {discount = .25}
var price = q * v;
var savings = price * discount;
var total = price - savings;
return total;
}

这是您只需修改HTML的id和类所需的引用
