isDisabled: function () {//基础商品表单是否禁用 let flag = formType == 2 ? true : false;//查看 禁用表单编辑 flag = flag ? flag : goodsInfo.flagSta == true ? true : false;//若被其他类型引用也禁用表单 return flag; }什么意思

这是一段 JavaScript 代码,其中定义了一个名为 `isDisabled` 的函数。这个函数的作用是判断基础商品表单是否应该被禁用。具体来说:
- 如果 `formType` 的值为 2,则禁用表单编辑;
- 如果 `goodsInfo.flagSta` 的值为 true,则禁用表单编辑;
- 如果表单已经被其他类型引用,则禁用表单编辑。
最终,函数返回一个布尔值,表示表单是否应该被禁用。

以下是代码优化:
1. 将CSS样式重构为BEM命名规范,方便代码维护和拓展;
2. 对于按钮样式,使用CSS变量来定义颜色和字体大小,方便后期修改;
3. 为了更好的用户体验,增加了loading状态,避免用户误操作造成不必要的错误。

可以直接将async关键字去掉,改为普通的函数即可。如下所示:
function changeNumber(target) {
let param = {
url: '/cart/number',
argument: {
id: localStorage.getItem('userId'),
goodsId: target.parentElement.parentElement.dataset.goodsid,
// number: --target.nextElementSibling.value
}
}
if (target.className == 'deleteGoods') {
param.argument.number = --target.nextElementSibling.value
if (param.argument.number == 0) {
target.nextElementSibling.value = 1
target.disabled = true
return
}
}
if (target.className == 'addGoods') {
param.argument.number = target.previousElementSibling.value
target.previousElementSibling.previousElementSibling.disabled = false
}
let res = ajax_post(param)
if (res.code == 1) {
this.renderCarList()
}
}
