密码重置需要输入原密码以及对新密码进行校验

首先就是搭建一个页面

!--pages/password/password.wxml--!-- textpages/password/password.wxml/text --form bindsubmit='formSubmit'view class='old'  text原密码/text  input password='true' name='oldpwd' placeholder='请输入原密码' //viewview class='new'  text新密码/text  input password='true' name='newpwd' placeholder='请输入新密码' //viewview class='ok'  text确认新密码/text  input password='true' name='newpwd2' placeholder='请确认一遍新密码' //viewbutton type='primary' form-type='submit'提交/button/form

对页面进行样式设定

/* pages/password/password.wxss */.old{  height: 150rpx;  background-color: #fff;  margin: 20rpx;}.new{  height: 150rpx;  background-color: #fff;  margin: 20rpx;}.ok{  height: 150rpx;  background-color: #fff;  margin: 20rpx;}text{  /* margin-top: 50rpx; */  margin-left: 20rpx;}input{  margin-top: 30rpx;  margin-left: 20rpx;  border-bottom: 1px solid #777;}button{  margin: 20rpx;}

接下来就是js,对提交的数据进行验证

const app=getApp();// pages/password/password.jsPage({  /**   * 页面的初始数据   */  data: {    },  formSubmit:function(e){    // console.log(e);    var oldpwd=e.detail.value.oldpwd;    var newpwd = e.detail.value.newpwd;    var newpwd2 = e.detail.value.newpwd2;    var no = wx.getStorageSync('student').no;    // console.log(no);    if(oldpwd=='' || newpwd=='' || newpwd2==''){      wx.showToast({        title: '密码不能为空',        icon:'none',        duration:1000      })    }else if(newpwd!=newpwd2){      wx.showToast({        title: '两次输入不一致',        icon: 'none',        duration: 1000      })    }else{      var url = app.globalData.url.setpassword;      wx.request({        url: url, //仅为示例，并非真实的接口地址        method:'POST',        data: {          no: no,          oldpwd:oldpwd,          newpwd:newpwd        },        header: {          'content-type': 'application/x-www-form-urlencoded'         },        success: (res) = {          console.log(res.data);          if(res.data.error){            wx.showToast({              title: res.data.msg,              icon: 'none',              duration: 2000            })          }else{            wx.showToast({              title: res.data.msg,              icon: 'success',              duration: 2000,              success: function () {                setTimeout(function () {                  wx.navigateBack({ belta: 1 })                }, 2000)              }            })          }                 }      })    }  },  /**   * 生命周期函数--监听页面加载   */  onLoad: function (options) {    },  /**   * 生命周期函数--监听页面初次渲染完成   */  onReady: function () {    },  /**   * 生命周期函数--监听页面显示   */  onShow: function () {    },  /**   * 生命周期函数--监听页面隐藏   */  onHide: function () {    },  /**   * 生命周期函数--监听页面卸载   */  onUnload: function () {    },  /**   * 页面相关事件处理函数--监听用户下拉动作   */  onPullDownRefresh: function () {    },  /**   * 页面上拉触底事件的处理函数   */  onReachBottom: function () {    },  /**   * 用户点击右上角分享   */  onShareAppMessage: function () {    }})
