使用Bootrap和Vue实现仿百度搜索功能

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


<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">
    <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);

                        },{
                            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(){

                        }
                    },
                    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>
