第一种：自己实现

feedback.js：

const url = require('../../utils/requireurl.js').url;Page({  /**   * 页面的初始数据   */  data: {    loading: false,    contact: '',    contant: ''  },  formSubmit: function (e) {    let _that = this;    let content = e.detail.value.opinion;    let contact = e.detail.value.contact;    let regPhone = /^1[3578]d{9}$/;    let regEmail = /^[a-zd_-.]+@[a-zd_-]+.[a-zd_-]+$/i;    if (content == "") {      wx.showModal({        title: '提示',        content: '反馈内容不能为空!',      })      return false    }    if (contact == "") {      wx.showModal({        title: '提示',        content: '手机号或者邮箱不能为空!',      })      return false    }    if (contact == "" && content == "") {      wx.showModal({        title: '提示',        content: '反馈内容,手机号或者邮箱不能为空!',      })      return false    }    if ((!regPhone.test(contact) && !regEmail.test(contact)) || (regPhone.test(contact) && regEmail.test(contact))) { //验证手机号或者邮箱的其中一个对      wx.showModal({        title: '提示',        content: '您输入的手机号或者邮箱有误!',      })      return false    } else {      this.setData({        loading: true      })      let model, system, platform;      wx.getSystemInfo({        success: function (res) {          model = res.model;          system = res.system;          platform = res.platform;        }      })      wx.request({        url: url + '/util/feedback',        header: {          'content-type': 'application/x-www-form-urlencoded'        },        data: {          'content': content,          'contact': contact,          'device_model': model, //手机型号          'device_system ': system, //操作系统版本          'app_version': platform  //客户端平台        },        method: 'POST',        success: function (res) {          let status = res.data.status;          if (status == 1) {            _that.setData({              loading: false,              contact: '',              contant: ''            })            wx.showToast({              title: '成功',              icon: 'success',              duration: 1500            })          }        },        fail: function () {          console.log("意见反馈接口调用失败")        }      })    }  },})

feedback.wxml：

!--pages/feedback/feedback.wxml--view class="opinion_wrap"  form bindsubmit="formSubmit"      view class="content_wrap"          view class="content"              textarea name="opinion"   value="{{content}}" auto-height placeholder-class="placeholder" placeholder="期待您的反馈，我们将会不断改进(ง •̀_•́)ง" /          /view      /view        view class="phone"          input name="contact" value="{{contact}}" placeholder-class="placeholder" placeholder="请留下您的手机号或邮箱，方便我们及时回复" /      /view      button formType="submit" hover-class="none" loading="{{loading}}"提交/button  /form/view

feedback.wxss：

/* pages/feedback/feedback.wxss */page{    background-color: #efefef;}.content_wrap{    background-color: #fff;}.content{    padding: 10rpx;    margin: 0 auto}textarea{    min-height: 300rpx;    width: 100%;}input{    margin-top: 30rpx;    height: 100rpx;    padding-left: 20rpx;    background-color: #fff;}button{    width: 80%;    margin-top: 30rpx;    background-color: #696969;    color: #fff;}.placeholder{    color: #b6b6b6;    font-size: 14px;}
