<input type="number" id="input1" bindinput="handleInput1" value="{{input1}}"/> *
<input type="number" id="input2" bindinput="handleInput2" value="{{input2}}"/> =
<button bindtap="calculate">计算</button>
<view  id="result">
    <view wx:for="{{resultList}}">{{item}}</view>
</view>

Page({
  data: {
    result: [],
    input1: '',
    input2: '',
  },
  onLoad: function () {
    console.log('Welcome to Mini Code')
  },
  calculate: function () {
    const { input1, input2,resultList } = this.data
    if (input1 === '' || input2 === '') {
      wx.showToast({
        title: '请输入正确的数字',
        duration: 2000,
        icon: 'warning'
      });
    } else {
     resultList.push(`${input1} * ${input2} = ${input1 * 1 * input2}`)
    this.setData({
     resultList
    }, () => {
    wx.cloud.callFunction({
      name: 'result',
      data: resultList
    }).then(console.log)
})
    }
  },
  handleInput1: function (e) {
    this.setData({
      input1: e.detail.value
    })
  },
  handleInput2: function (e) {
    this.setData({
      input2: e.detail.value
    })
  }
})
