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.$http.jsonp("https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su",{
              wd:this.txt
            },{
              jsonp:"cb"
            }).then(function(res){
              this.myData=res.data.s
            },function(res){
              alert(res.status);
            });
          },
          changeDown:function(){
            this.nowIndex++;
            if(this.nowIndex==this.myData.length){
              this.nowIndex=0;
              this.txt=this.myData[0];
            }else{
              this.txt=this.myData[this.nowIndex];
            }
          },
          changeUp:function(){
            this.nowIndex--;
            if(this.nowIndex==-1){
              this.nowIndex=this.myData.length-1;
              this.txt=this.myData[this.nowIndex];
            }else{
              this.txt=this.myData[this.nowIndex];
            }
          },
          mouseOver:function(n){
            this.nowIndex=n;
            this.txt=this.myData[this.nowIndex];
          },
          getMsg:function(){
            window.open("https://www.baidu.com/s?wd="+this.txt);
            this.txt="";
          }
        }
      });
    }
  </script>
</head>
<body>
  <br>
  <div class="container">
    <div class="input-group">
      <input type="text" class="form-control input-lg" placeholder="请输入关键字" v-model="txt" @keyup="get($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>
    </div>
    <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>
  </div>
</body>
</html>

实现效果如下
