let arr=r.result.feedGmBackVOs;

在JavaScript中，`let arr = r.result.feedGmBackVOs;` 这行代码的作用是创建了一个新的局部变量`arr`，并将它的值设置为对象`r.result`中名为`feedGmBackVOs`的属性。这里的`r`很可能是一个函数返回的对象，或者是某个API、回调函数的结果，`feedGmBackVOs`可能是包含了多个反馈对象（比如对象数组）的数据集。

这句代码假设`r.result`是一个包含嵌套结构的对象，其中`feedGmBackVOs`字段指向的是另一个对象或数组。通过这个赋值，你现在可以直接通过`arr`来访问和操作这些反馈对象。

举个例子，如果`feedGmBackVOs`是一个数组：

const r = { result: { feedGmBackVOs: [ { id: 1, name: 'Feedback 1' }, { id: 2, name: 'Feedback 2' } ] } };
let arr = r.result.feedGmBackVOs;
console.log(arr[0].name); // 输出 'Feedback 1'

lifetimes: { attached() { let that = this let userPhoneStr = '' let userEmailStr = '' let peopleNameStr = '' let userPhone = '' let userPhoneInvoice = wx.getStorageSync('memberMsg').memberMobile userPhone = userPhoneInvoice let arr = userPhoneInvoice.split('') for (let x = 0; x < arr.length; x++) { if ((x >= 0 && x <= 2) || (x >= 7 && x < arr.length)) { userPhoneStr += arr[x] } else { userPhoneStr += '*' } } if (wx.getStorageSync('userEmailInvoice') != '') { userEmailStr = wx.getStorageSync('userEmailInvoice') } if (wx.getStorageSync('userNameInvoice') != '') { peopleNameStr = wx.getStorageSync('userNameInvoice') } this.setData({ userPhoneStr, userEmailStr, peopleNameStr, userPhone }) wx.getSystemInfo({ success: e => { that.setData({ pageHeight: e.windowHeight, invoiceModalMaxHeight: e.windowHeight * 0.6 }) if (that.data.isiPhoneX) { that.setData({ invoiceModalScrollMaxHeight: e.windowHeight * 0.6 - 120 }) } else { that.setData({ invoiceModalScrollMaxHeight: e.windowHeight * 0.6 - 90 }) } } }) } }, 改成uniapp

可以将该段代码转换为uni-app的语法：

export default {
  onReady() {
    let that = this;
    let userPhoneStr = '';
    let userEmailStr = '';
    let peopleNameStr = '';
    let userPhone = '';
    let userPhoneInvoice = uni.getStorageSync('memberMsg').memberMobile;
    userPhone = userPhoneInvoice;
    let arr = userPhoneInvoice.split('');
    for (let x = 0; x < arr.length; x++) {
      if ((x >= 0 && x <= 2) || (x >= 7 && x < arr.length)) {
        userPhoneStr += arr[x];
      } else {
        userPhoneStr += '*';
      }
    }
    if (uni.getStorageSync('userEmailInvoice') != '') {
      userEmailStr = uni.getStorageSync('userEmailInvoice');
    }
    if (uni.getStorageSync('userNameInvoice') != '') {
      peopleNameStr = uni.getStorageSync('userNameInvoice');
    }
    this.setData({
      userPhoneStr,
      userEmailStr,
      peopleNameStr,
      userPhone
    });
    uni.getSystemInfo({
      success: e => {
        that.setData({
          pageHeight: e.windowHeight,
          invoiceModalMaxHeight: e.windowHeight * 0.6
        });
        if (that.data.isiPhoneX) {
          that.setData({
            invoiceModalScrollMaxHeight: e.windowHeight * 0.6 - 120
          });
        } else {
          that.setData({
            invoiceModalScrollMaxHeight: e.windowHeight * 0.6 - 90
          });
        }
      }
    });
  }
}

注意，我将`attached`改为了`onReady`，因为在uni-app中没有`attached`这个生命周期函数。另外，我使用了`uni.`代替了`wx.`，因为uni-app是跨平台框架，需要使用uni-app提供的API。

function getCateList(cateId) { let arr = []; const filterCate = (id) => { productCateList({ id, siteType: '01', platformType: '01' }).then( (res) => { arr = [...res.data, ...arr]; if (res.data[0].parentId && res.data[0].parentId !== '0') { return filterCate(res.data[0].parentId); } else { return arr; } } ); }; return filterCate(cateId);} 修复

修改后的代码如下：

function getCateList(cateId) {
  let arr = [];

  const filterCate = (id) => {
    return productCateList({ id, siteType: '01', platformType: '01' }).then(
      (res) => {
        arr = [...res.data, ...arr];
        if (res.data[0].parentId && res.data[0].parentId !== '0') {
          return filterCate(res.data[0].parentId);
        } else {
          return arr;
        }
      }
    );
  };

  return filterCate(cateId);
}

我添加了一个 `return` 语句，以便 `filterCate` 函数返回一个 Promise 对象，以便在获取完所有子分类后，通过 Promise 对象解析来获取结果。
