效果图如下所示：
首先上代码
<template>
<div class="assets-search height-all">
<div class="search-layout">
<div class="search-title">让数据触手可及</div>
<div class="search-input-layout">
<!--<el-input class="search-input" placeholder="检索数据"
@keyup.enter.native="searchAssets($event)"
v-model="searchContent">
<el-button style="color: white"
@click="searchAssets(searchContent)"
slot="append">搜 索</el-button>
</el-input>-->
<el-autocomplete
class="inline-input search-input"
v-model="searchContent"
ref="autocomplete"
:fetch-suggestions="requestDoSuggest"
placeholder="请输入您需要检索资源名称或者中文"
@keyup.enter.native="searchAssets($event)"
:trigger-on-focus="false"
@select="handleSelect"
>
<el-button @click="searchAssets" slot="append">搜 索</el-button>
</el-autocomplete>
<div class="search-word-layout" v-show="searchWordList.length">
<span class="search-word-title">热门搜索：</span>
<div class="search-word-list">
<span class="search-word"
v-for="(item, index) in searchWordList"
@click="clickHotWord(item)"
:key="index">{{item}}</span>
</div>
</div>
</div>
<el-button v-if="false" class="db-number-layout">{{`资产库：${ddNumber}`}}</el-button>
</div>
</div>
</template>

注意的细节
基础使用
fetch-suggestions这个方法是去请求包含关键字的搜索功能，这里注意返回结果里面的列表对象属性里面要有一个value的属性，这个才能显示，联想输入内容。
select 方法是选择了一个联想输入的具体数据的点击事件
注意事项
按enter键进行搜索功能@keyup.enter.native="searchAssets(event)"，有些人会好奇，这个 event)"，有些人会好奇，这个event)"，有些人会好奇，这个event是一个什么东西，其实就是一个事件，代码
if (event) {
event.target.blur();
this.$refs.autocomplete.close();
}
这个是为了处理点击enter使input输入框失去焦点，还有一个作用就是，让el-autocomplete 的联想输入框关闭。这个达到和百度搜索类似的效果。
