} 2.第二种模拟动态方法 效果如上图所示:（省略） 代码: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>view的tab交互</title> <link rel="stylesheet" href="../css/demo.css" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" > </head> <body> <div class="demo_warp" id="my"> <ul class="tab_tit"> <li v-for="(v,i) in title" :class="n==i?"active":""" @click="n=i">{{v}}</li> </ul> <!-- neirong --> <div class="tab_con"> <div v-for="(v,i) in con" v-show="n==i">{{v}}</div> </div> </div> <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script> <script> Vue.config.productionTip=false </script> <script src="../js/tab.js" type="text/javascript"></script> </body> </html> css *{ margin: 0; padding: 0; box-sizing:border-box; } body,html{ height: 100%; } .demo_warp .tab_tit { display: flex; flex: 1; margin:.2rem; } .demo_warp .active { color:red; background-color: cadetblue; } .demo_warp ul li { list-style: none; width: 23%; text-align: center; background-color: #ccc; margin:0 1%; } .demo_warp .tab_con { width: 100%; height: 3rem; border:1px solid rgb(85, 85, 177); text-align: center; } js window.onload=function(){ new Vue({ el:"#my", data:{//响应式的数据 data变化页面也会跟着变化 n:0, title:["标题一","标题二","标题三","标题四"], con:["内容一","内容二","内容三","内容四"] } }) } 3.第三种动态数据方法 代码: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>view的tab交互</title> <link rel="stylesheet" href="../css/demo.css" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" > </head> <body> <div class="demo_warp" id="my"> <ul class="tab_tit"> <li v-for="(v,i) in lists" :class="n==i?"active":""" @click="n=i">{{v.title}}</li> </ul> <!-- neirong --> <div class="tab_con"> <div v-for="(v,i) in lists" v-show="n==i">{{v.con}}</div> </div> </div> <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script> <script> Vue.config.productionTip=false </script> <script src="../js/tab.js" type="text/javascript"></script> </body> </html> css *{ margin: 0; padding: 0; box-sizing:border-box; } body,html{ height: 100%; } .demo_warp .tab_tit{ display: flex; justify-content: space-between; white-space: nowrap; overflow-y: hidden; overflow-x: scroll; margin:1% 1% 1% 0; } ::-webkit-scrollbar{ display: none; } .demo_warp .active { color:red; background-color: cadetblue; } .demo_warp ul li { list-style: none; padding:1.2% 3.2%; text-align: center; background-color: #ccc; margin-left: 1%; } .demo_warp .tab_con { width: 100%; height: 3rem; border:1px solid rgb(85, 85, 177); text-align: center; } js window.onload=function(){ new Vue({ el:"#my", data:{//响应式的数据 data变化页面也会跟着变化 n:0, lists:[//可以有很多条数据//数组对象的形式 {title:"标题一",con:"内容一"}, {title:"标题二",con:"内容二"}, {title:"标题三",con:"内容三"}, {title:"标题四",con:"内容四"}, {title:"标题五",con:"内容五"}, {title:"标题六",con:"内容六"}, {title:"标题七",con:"内容七"}, {title:"标题八",con:"内容八"}, ] } }) } 4.动态实现方法(模拟后台数据实现) 代码: <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>view的tab交互</title> <link rel="stylesheet" type="text/css" href="../css/demo.css" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" > </head> <body> <div class="demo_warp" id="my"> <ul class="tab_tit"> <li v-for="(v,i) in lists" :class="m==i?"active":""" @click="m=i" :key="i.title">{{v.title}}</li> </ul> <!-- neirong --> <div class="tab_con"> <div v-for="(v,i) in lists" v-show="m==i" :key="i.con">{{v.con}}</div> </div> <!-- -----------动态数据----------- --> <ul class="tab_tit"> <li v-for="(item, index) in itemList" :class="n==index?"active":""" @click="n=index" :key="index">{{item.name}}</li> </ul> <!-- neirong --> <div class="tab_con"> <div v-for="(item, index) in itemList" v-show="n==index" :key="index">{{item.state}}</div> </div> </div> <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script> <script> Vue.config.productionTip=false </script> <script src="../node_modules/axios/dist/axios.js"></script> <script src="../js/tab.js" type="text/javascript"></script> </body> </html> css *{ margin: 0;

} ::-webkit-scrollbar{ display: none; } .demo_warp .active { color:red; background-color: cadetblue; } .demo_warp ul li { list-style: none; padding:1.2% 3.2%; text-align: center; background-color: #ccc; margin-left: 1%; } .demo_warp .tab_con { width: 100%; height: 3rem; border:1px solid rgb(85, 85, 177); text-align: center; } tab.js window.onload=function(){ new Vue({ el:"#my", data(){//响应式的数据 data变化页面也会跟着变化 return{ n:0, m:0, lists:[ {title:"标题一",con:"内容一"}, {title:"标题二",con:"内容二"}, {title:"标题三",con:"内容三"}, {title:"标题四",con:"内容四"}, {title:"标题五",con:"内容五"}, {title:"标题六",con:"内容六"}, {title:"标题七",con:"内容七"}, {title:"标题八",con:"内容八"}, ], itemList:[] } }, methods:{ getList:function(){//this:--【函数和定时器的this指向都是window (而我们是要this指向vue实例)】 var that=this;//局部定义改变this指向 //每执行此方法，提前清空数组，保证往下执行代码，数组为空 // this.itemList = []; axios({ method:"get", url:"http://localhost:4000/list" }).then(function(res){ console.log(res); that.itemList = res.data.result; }).catch(function(error){ console.log(error); }) } }, mounted:function(){ this.getList(); }, }) } nodeServer.js /* connect 是一个node中间件 (middeware)框架 如果把一个http处理过程比作是污水处理 中间件就像是一层层的过滤网 每个中间件把http处理过程中通过改写 request或(和)response的数据、状态、实现了特定的功能 中间件就是类似于一个过滤器的东西 在客户端和应用程序之间的一个处理请求和响应的方法. */
//创建中间介 启动服务 node node.js var connect = require("connect");//创建连接 var bodyParser=require("body-parser");//body解析 用于处理 JSON、RAW、Text和URL编码的数据. var lists = {}; var app = connect() .use(bodyParser.json())//JSON解析 .use(bodyParser.urlencoded({extended:true})) //use()方法还有一个可选的路径字符串 对传入请求的URL的开始匹配 //use()方法来维护一个中间件队列 .use(function(req,res,next){ //跨域处理 //website you wish to allow to connect res.setHeader("Access-Control-Allow-origin","*");//允许任何源 //Request Methods you width to allow res.setHeader("Access-Control-Allow-Methods","CET","POST","OPTIONS","PUT","PATCH","DELETE");//允许任何方法 //Request headers you wish to allow res.setHeader("Access-Control-Allow-Headers","*");//允许任何类型 res.writeHead(200,{"Content-Type":"text/plain/xml;charset=utf-8"});//utf-8转码 next();//next方法就是一个递归调用 }) .use("/list",function(req,res,next){ var data={ "code":"200", "msg":"success", "result":[ {name:"手机",state:"采购一"}, {name:"包包",state:"采购二"}, {name:"衣服",state:"采购三"}, {name:"电脑",state:"采购四"}, {name:"电子产品",state:"采购五"} ] } res.end(JSON.stringify(data)); next(); }) .use("/list_get",function(req,res,next){ var data={ "code":"200", "msg":"success", "result":lists } res.end(JSON.stringify(data)); next(); }) .use("/list_add",function(req,res,next){ if(req.method=="POST"){ console.log(req.body.name); lists.push({name:req.body.name,state:req.body.state,id:index++}); var data={"code":200,"msg":"success"}; res.end(JSON.stringify(data)); }else{ res.end(JSON.stringify({})); } next(); }) .use("/list_del",function(req,res,next){ console.log(req.body.id); //lists=lists.filter(list=>list.id!=req.body.id); for(var i=0;i<lists.length;i++){ if(req.body.id===lists[i].id){ lists.splice(i,1); } } console.log(lists); var data={"code":200,"msg":"success"}; res.end(JSON.stringify(data)); next(); }) .listen(4000); console.log("Server started on port 4000."); 插件:（需要下载的插件） 1.先启动服务node nodeServer.js（不能关闭，否则就会调取不到数据） 2.之后运行html页面 。 项目遇到的bug: vue中v-for循环遍历后，当前内容不渲染的问题,因为this指向的问题导致. 总结:url：接口要写自己后台的接口哦，这里只是模拟的接口,nodeServer.js文件可以定义多种格式的数据类型，也可以在本地自定义嵌套多种需要的类型，先试用之后可以在调后台数据。 （编辑：银川站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
