javascript - 我的自动表单不会输出正确的值
问题描述
我正在尝试构建一个自动估计器表单，但是当我做宽度 30 英尺和长度 16 英尺时，我在 mytotal 上得到 000000000003 一些位丢失但所有的 ifs 但它仍然输出不同
我已经尝试了一切，但我无法让它工作有人可以帮忙吗 https://codepen.io/callum-edwards/pen/oNvBWxo

解决方案
由于您的示例提供了两个十进制数字的用法，因此我建议您快速修复。
在calculate()函数的底部（在最后一个if条件之后），添加以下行来解析内容：
let p = $("#plaster")
p.html( Math.round(+p.html() * 1000) / 1000 )
这是将整个浮点值减少到只有两个十进制值（如果有必要）的技巧。这样做，每次调用函数时，您的代码都会将该数字解析为两个十进制数字。
看到它工作：
$(function() {
$(function() {
var fields = $(
"select[name=bead],select[name=cpu],select[name=GPU]"
).change(calculate);
function calculate() {
var price = 0;
fields.each(function() {
price += +$(this).val();
