最近写小程序项目遇到一些问题,今天整理下这些问题的解决方法,希望对用户有帮助。下面是登录页,点击登录时获取input框中的值,
效果如下:
wxml布局如下: <view > <input type="text" placeholder-style="color:#fff;" bindinput="userNameInp" placeholder="请输入账号" /> </view> <view > <input password placeholder-style="color:#fff;" bindinput="usePasswordInp" placeholder="请输入密码"/> </view> <button class="loginBtn" bindtap=‘loginFn‘>登录</button> js代码如下: const app = getApp(); Page({ /** * 页面的初始数据 */ data: { userName: "", passWord: "", }, //监听输入的账号 userNameInp: function (e) { this.data.userName = e.detail.value; }, //监听输入的密码 usePasswordInp: function (e) { this.data.passWord = e.detail.value; }, //登录 loginFn: function () { var that = this; if (that.data.userName.length == 0 || that.data.passWord.length == 0) { wx.showToast({ title: ‘账号或密码为空‘, icon: ‘loading‘, duration: 2000 }) } else { wx.showLoading({ title: ‘登录中...‘, }) wx.request({ url: ‘https://localhost:8180/exam/login‘, data: { username: that.data.userName, password: that.data.passWord }, header: { ‘content-type‘: ‘application/x-www-form-urlencoded‘ // 默认值 }, method: ‘post‘, success: function (res) { wx.hideLoading(); wx.removeStorageSync(‘sessionid‘); // console.log(‘登录成功‘, res.data.data); if (res.data.code == "0000") { wx.showToast({ title: ‘登录成功‘, icon: ‘success‘, duration: 1000 }) wx.setStorageSync(‘sessionid‘, res.header[‘Set-Cookie‘]); //保存Cookie到Storage wx.setStorage({ key: ‘myData‘, data: res.data.data }) wx.redirectTo({ url: ‘/pages/index/index‘, }) } else { wx.showToast({ title: ‘登录失败‘, icon: ‘none‘, duration: 2000 }) } }, fail: function (e) { wx.showToast({ title: ‘服务器出现错误‘, icon: ‘none‘, duration: 2000 }) } }) } }, //跳转到忘记密码页面 onTapDayWeather() { wx.navigateTo({ url: ‘/pages/updatepwd/updatepwd‘, }) }, /** * 生命周期函数--监听页面加载 */ onLoad: function (options) { }, })
