家庭记账本---开发进度1

今天我下载了微信web开发者工具，并在网上找到了别人的代码，以作参考研究。

//index.js

var util = require("../../utils/util.js");
//获取应用实例
var app = getApp();
Page({
  data: {
    userInfo: {},
    buttonLoading: false,
    accountData: [],
    accountTotal: 0
  },
  onLoad: function () {
    console.log('onLoad')
    var that = this;

    // 获取记录
    var tempAccountData = wx.getStorageSync("accountData") || [];
    this.caculateTotal(tempAccountData);
    this.setData({
      accountData: tempAccountData
    });

  },
  // 计算总额
  caculateTotal: function (data) {
    var tempTotal = 0;
    for (var x in data) {
      tempTotal += parseFloat(data[x].amount);
    }
    this.setData({
      accountTotal: tempTotal
    });
  },
  //表单提交
  formSubmit: function (e) {
    this.setData({
      buttonLoading: true
    });

    var that = this;
    setTimeout(function () {
      var inDetail = e.detail.value.inputdetail;
      var inAmount = e.detail.value.inputamount;
      if (inDetail.toString().length <= 0 || inAmount.toString().length <= 0) {
        console.log("can not empty");
        that.setData({
          buttonLoading: false
        });
        return false;
      }

      //新增记录
      var tempAccountData = wx.getStorageSync("accountData") || [];
      tempAccountData.unshift({ detail: inDetail, amount: inAmount });
      wx.setStorageSync("accountData", tempAccountData);
      that.caculateTotal(tempAccountData);
      that.setData({
        accountData: tempAccountData,
        buttonLoading: false
      });

    }, 1000);
  },
  //删除行
  deleteRow: function (e) {
    var that = this;
    var index = e.target.dataset.indexKey;
    var tempAccountData = wx.getStorageSync("accountData") || [];
    tempAccountData.splice(index, 1);
    wx.setStorageSync("accountData", tempAccountData);
    that.caculateTotal(tempAccountData);
    that.setData({
      accountData: tempAccountData,
    });
  }
})
