HTML 代码
<div class="container search-container" id="app">
<h1 class="title" >baidu-search</h1>
<input type="text" class="form-control" placeholder="请输入想要搜索关键字" v-model="keyword" @keyup="get($event)" @keydown.down.prevent="selectDown"
@keydown.up.prevent="selectUp">
<ul>
<li class="text-center" v-for="(value,index) in myData"><span class="text-success textprimary" :class="{gray:index==now}">{{value}}</span></li>
</ul>
<p ><h2 v-show="myData.length==0" class="text-warning text-center">(*^__^*)暂时没有数据</h2></p>
</div>
get方法实现获取下拉数据和搜索功能,输入keyword之后,调用get方法使用jsonp获取提示数据,然后赋值给myData,然后使用v-for遍历提示数据
然后selectDown和selectUp实现上下选中数据,当按下回车键时,实现搜索
