点击：需要用户登陆才能进去页面，否则弹出登陆框

利用原理：用户登陆后缓存的标识，和全局方法，引入全局组件！登陆样式.login_mask {    background: rgba(0, 0, 0, 0.4);    width: 100%;    height: 100%;    position: fixed;    top: 0;    left: 0;    z-index: 1996;    display: flex;    align-items: center;}.login_main {    width: 652rpx;    height: 800rpx;    background: #f8f8f9;    margin: 0 auto;    /* margin-top: 100rpx; */    border-radius: 10rpx;    position: relative;    text-align: center;}.login_main .icon-guanbi {    position: absolute;    right: 40rpx;    top: 40rpx;    z-index: 88;    font-size: 40rpx;}.login_main .logo {    width: 60rpx;    height: 60rpx;    border-radius: 50%;    margin: 42rpx 0;}.login_main .title {    font-size: 28rpx;    color: #00274b;}.login_main .email {    width: 544rpx;    height: 88rpx;    border: 1px solid #bbc9d6;    margin: 0 auto;    border-radius: 44rpx;    text-align: left;    padding-left: 32rpx;    margin-top: 40rpx;}.login_main .password {    width: 544rpx;    height: 88rpx;    border: 1px solid #bbc9d6;    margin: 0 auto;    border-radius: 44rpx;    text-align: left;    padding-left: 32rpx;    margin-top: 40rpx;}.login_main .eye {    position: absolute;    width:100rpx;    height: 88rpx;    right: 50rpx;    top: 17rpx;    z-index: 150;}.forget {    height: 80rpx;    line-height: 80rpx;    color: #03a9f4;    font-size: 24rpx;}.termsOfService {    font-size: 24rpx;    color: #97a7b7;    margin-top: 48rpx;}.noAccount {    font-size: 24rpx;    color: #97a7b7;    margin-top: 38rpx;}.service,.register{    color:#03a9f4;}.submit {    width: 544rpx;    height: 88rpx;    line-height: 88rpx;    border-radius: 44rpx;    /* background: #93d6f8; */    background:#03a9f4;     color: #fff;    font-size: 34rpx;}

在需要用到的页面引入!-- 引入登陆模态框 --import src="../login/login.wxml" /template is="login" data="{{showpass,eye,password,email,focus,logShow}}"/templateview bindtap='islogin'点击打卡/view

jsvar util = require('../../utils/util.js'),   Page({              data: {            logShow: false        },//切换密码是否可见        switchEye() {            var that = this;            util.switchEye(that, that.data.eye, that.data.showpass)        },//获取密码        getPassWord: function(e) {            var that = this;            var password = e.detail.value;            util.getPassWord(that, password)        },//获取邮箱        getEmail(e) {            var that = this;            var email = e.detail.value;            util.getEmail(that, email)        },//关闭模态框        close() {            var that = this;            util.close(that)        },        islogin() {                     if (用户登陆的标识，可以在登陆后存到缓存里面，然后在缓存取) {                this.setData({                    logShow: true                })            } else {                           wx.navigateTo({                   url: '跳转的页面',               })            }        },        onLoad: function(options) {                 },          }  )
