    A页面调用B页面

    B页面是扫描页面

    需要在A页面中引用mui.css 和 mui.js

    A页面
    <img src="../images/scanning.png" class="iconfont icon-scanning" id="turnTheLight" v-on:click="scans()"></img>
    <input type="text" class="weui-input m-t2" placeholder="输入地址" id="url" v-model="result">

    <script> var vm = new Vue({ el: '#box', data: { token: "", result: '' }, created: function () { var that = this that.token = localStorage.getItem('token') // alert(window.location.href) that.result = that.GetRequest() // alert(that.result) }, methods: { GetRequest: function () { var url = location.search; //获取url中"?"符后的字串 var theRequest = new Object(); if (url.indexOf("?") != -1) { var str = url.substr(1); strs = str.split("="); var theRequest = strs[1] // alert(strs[1]) } return theRequest; $(".URL").css("display", "block") }, scans: function () { console.log(1) var that = this window.location.href = "scans.html?type=" + 4; } } }); </script>
    B页面
