input组件Bug
发布于 7 年前 作者 cqiao 2289 次浏览 来自 问答

已上线小程序，通过input输入修改数据库数据时每次输入2.28数据库后台会更新成2.27999999999999999997，不知什么原因？

<view class=“input_box”>

<label>请输入单独购买价格：</label>

<input type=‘text’ name=“mprice” placeholder="{{item.mprice/100}}" value="{{item.mprice/100}}" />

</view>

wx.showModal({
  content: '是否更新产品？',
  success: function(res) {
    if (res.confirm) {
      wx.cloud.callFunction({
          name: 'updateproduct',
          data: {
            type: 'updateproducts',
            data: {
              id2: e.detail.target.dataset.id,
              endTime2: e.detail.value.endTime,
              gprice2: e.detail.value.gprice * 100,
              groupSize2: e.detail.value.groupSize,
              maxNum2: e.detail.value.maxNum,
              mprice2: e.detail.value.mprice * 100,
              unit2: e.detail.value.unit,
              name2: e.detail.value.name,
              sort2: Number(e.detail.value.sort),
              serviceNote2: e.detail.value.servicenote,
              cid2: Number(self.data.cid),
              sale_flag: sale_flag
            }
          }
        })
        .then(res => {
          wx.showToast({
            title: '更新产品成功',
            icon: 'success'
          })

以下为云函数代码

  return await goodsorderCollection.doc(id2)
    .update({
      data: {
        endTime: endTime2,
        gprice: gprice2,
        groupSize: groupSize2,
        maxNum: maxNum2,
        mprice: mprice2,
        unit: unit2,
        name: name2,
        sort: sort2,
        serviceNote: serviceNote2,
        cid: cid2,
        sale_flag: sale_flag,
      }
    })
} catch (e) {
  console.error(e)
}
