用Vue调用百度的搜索接口,实现简单的搜索功能。
搜索框的样式是基于Bootstrap,当然对样式做了简单的调整, 使之类似于百度搜索。代码如下
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>百度搜索</title> <style type="text/css"> .gray{ background-color: #eee; } .listyle{ font-size: 16px; line-height: 35px; padding-left: 16px; } .ulstyle{ border:1px solid #ccc; border-top: none; } </style> <link rel="stylesheet" type="text/css" href="bootstrap.min.css" rel="external nofollow" > <script type="text/javascript" src="vue.js"></script> <script type="text/javascript" src="vue-resource.js"></script> <script type="text/javascript"> window.onload = function(){ new Vue({ el: ".container", data: { myData:[], txt:"", nowIndex:-1 }, methods:{ get:function(event){ if(event.keyCode==38 || event.keyCode==40){ return; } if(event.keyCode==13){ window.open("https://www.baidu.com/s?wd="+this.txt); this.txt=""; } this.$http.jsonp("https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su",{ wd:this.txt },{ jsonp:"cb" }).then(function(res){ this.myData=res.data.s },function(res){ alert(res.status); }); }, changeDown:function(){ this.nowIndex++; if(this.nowIndex==this.myData.length){ this.nowIndex=0; this.txt=this.myData[0]; }else{ this.txt=this.myData[this.nowIndex]; } }, changeUp:function(){ this.nowIndex--; if(this.nowIndex==-1){ this.nowIndex=this.myData.length-1; this.txt=this.myData[this.nowIndex]; }else{ this.txt=this.myData[this.nowIndex]; } }, mouseOver:function(n){ this.nowIndex=n; this.txt=this.myData[this.nowIndex]; }, getMsg:function(){ window.open("https://www.baidu.com/s?wd="+this.txt); this.txt=""; } } }); } </script> </head> <body> <br> <p class="container"> <p class="input-group"> <input type="text" class="form-control input-lg" placeholder="请输入关键字" v-model="txt" @keyup="get($event)" @keydown.down="changeDown()" @keydown.up="changeUp()"> <span class="input-group-btn"> <button class="btn btn-default btn-lg" type="button" @click="getMsg()">搜索</button> </span> </p> <ul class="list-unstyled ulstyle" v-show="myData.length!=0"> <li v-for="item in myData" :class={gray:$index==nowIndex,listyle:true} @mouseover="mouseOver($index)" @click="getMsg()">{{item}}</li> </ul> </p> </body> </html>
