我试图添加总量和价格,似乎无法获得数量部分工作。我正在计算每立方码的总立方码和价格。提前谢谢。

答案 0 :(得分:0)
您的var quantity
选择器似乎多余。我是否正确地假设您要总结所有您的.quantity
字段?如果是这样,我不明白为什么你必须首先遍历到最近的ul
。
我做了我认为你想要实现的简化版本:JS Bin
基本上我只是简化了你的calculateQuantity
功能:
function calculateQuantity() {
var sum = 0;
$(".quantity").each(function() {
var q = parseFloat($(this).val());
if(!isNaN(q)) {
$(this).val(q.toFixed(2));
sum += q;
}
});
$('#cubicYards').val(sum.toFixed(2));
};
看看它是否适合你。
