2、js


import request from '../../../utils/request'
const app = getApp()
Page({
  data: {
    type: 1, //默认第一次输入密码
    onePassdWord: '', //请输入密码
    twoPassdWord: '', //再次输入密码
    themeColor: app.globalData.themeColor
  },

  onLoad(query) {
  },

  onShow() {
    wx.setNavigationBarColor({
      backgroundColor: app.globalData.color,
      frontColor: '#ffffff'
    })
  },
  getFocus() {
    console.log('this.data.type--getFocus', this.data.type);
    this.setData({
      isFocus: true,
    });
  },
  // 获取输入数字
  getCode(e) {
    const type = this.data.type;
    const passdWord = e.detail.value; //获取到的密码
    this.setData({
      code: e.detail.value
    });
    console.log('获取输入数字', this.data.code)
    // 获取输入框值的长度
    let value_length = e.detail.value.length;
    if (value_length == 6) {
      console.log(666, passdWord, type);
      if (type == 1) {
        console.log(5555, type);
        this.setData({
          type: 2,
          code: '',
          isFocus: true,
          onePassdWord: passdWord,
        })
      } else {
        console.log(888, type);
        this.setData({
          twoPassdWord: passdWord,
        })
      }
      // console.log(999, this.data.onePassdWord, this.data.twoPassdWord);
      if (this.data.onePassdWord.length == 6 && this.data.twoPassdWord.length == 6) {
        if (this.data.onePassdWord === this.data.twoPassdWord) {
          this.upPaymentPassword()
          // console.log('两次密码一样');
        } else {
          wx.showToast({
            title: '两次密码不一致，请重新设置。',
            icon: 'error',
            duration: 2000
          })
          this.setData({
            type: 1,
            code: '',
            onePassdWord: '',
            twoPassdWord: '',
            isFocus: true,
          })
        }
      }
    }
  },
  async upPaymentPassword() {
    const res = await request('******', 'POST', { password: this.data.twoPassdWord })
    if (res.success) {
      wx.showToast({
        title: '密码设置成功',
        icon: 'success',
        duration: 2000
      })
      wx.redirectTo({ url: `/subpackages/withdraw/index` });
    }
