都说vuejs多么吊，看了它的基本语法之后，做了一个百度下拉框的玩意，但是要感谢一下肖总，他算是我的启蒙老师。
代码如下，用这个框架，如果你只专注数据，那么你已经成功了！
代码如下：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>交互</title> <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0"> <meta name="apple-mobile-web-app-capable" content="yes"> <meta name="apple-mobile-web-app-status-bar-style" content="black"> <style> .gray{ background: #ccc; } .uik li:hover{ background: #ccc; cursor: pointer; } </style> <script src="../js/vue.js"></script> <script src="../js/vue-resource.js"></script> <script> window.οnlοad=function(){ new Vue({ el:'#box', data:{ myData:[], t1:'', now:-1 }, methods:{ get:function(ev){ if(ev.keyCode==38 || ev.keyCode==40)return; if(ev.keyCode==13){ window.open('https://www.baidu.com/s?wd='+this.t1); this.t1=''; } this.$http.jsonp('https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su',{ wd:this.t1 },{ jsonp:'cb' }).then(function(res){ this.myData=res.data.s; },function(){ }); }, changeDown:function(){ this.now++; if(this.now==this.myData.length)this.now=0; this.t1=this.myData[this.now]; }, changeUp:function(){ this.now--; if(this.now==-2)this.now=this.myData.length-1; this.t1=this.myData[this.now]; }, itemTiao:function(index){ window.open('https://www.baidu.com/s?wd='+this.myData[index]); this.t1=''; this.myData=[]; } } }); }; </script> </head> <body> <div id="box"> <input type="text" v-model="t1" @keyup="get($event)" @keydown.down="changeDown()" @keydown.up.prevent="changeUp()"> <ul class="uik"> <li v-for="(item, index) in myData" :class="{gray:index==now}" @click="itemTiao(index)"> {{item}} {{index}} </li> </ul> <p v-show="myData.length==0">暂无数据...</p> </div> </body> </html> 你需要 vuejs和vue-resource.js两个文件。
