Javascript计算数量*价格 [英] Javascript calculate quantity * price

问题描述

我正在尝试将每种商品的数量和价格相乘以计算总数，但是我的警报中出现了错误.

I'm trying to multiply the quantity and the price for each item for calculating the total, but I'm getting an error in my alert.

$.each(data.items, function(index, d){
    var calcultest = d.price * d.qty;
    alert(calcultest)
});

推荐答案

使用parseFloat将字符串转换为Float

Use parseFloat to convert string to Float

$.each(data.items, function(index, d){
    var Price = d.price.replace(",",".");
    var calcultest = parseFloat(Price) * parseFloat(d.qty);
    alert(calcultest.toString().replace(".",","));
});
