Question

我已经设置了一个javascript代码来提供总计。我只需要将总数的4％添加到实际总数中。这就是我所拥有的

/* EXISTING WORKING TOTAL CODE */
$(function () {
$('.DoPricing').on("keyup",function () {
    var total = 0;
    $('.DoPricing').each(function () {
        total += parseFloat($(this).val()) || 0;
    });
    $('#TotalPrice').html('$' + total);
});
});

 /* NEW PERCENTAGE CODE BELOW THAT NEEDS INTEGRATED */
 /* The code below is suppose to add 4% to total once integrated*/

 var total = round_decimals(order_total, 2);
 frm.TOTAL.value = total + ((4/100)*total);

Answer 1

var total = 200;
total = total*1.04;
console.log(total); // 208

所以在你的情况下

$(function () {
 $('.DoPricing').on("keyup",function () {
    var total = 0;
    $('.DoPricing').each(function () {
        total += parseFloat($(this).val()) || 0;
    });
    $('#TotalPrice').html('$' + (total*1.04).toFixed(2));
 });
});

将输出208.00作为总数200。

如何整合这两个简单的JavaScript代码？
