如图所示，此为父组件中的数组数据
如图，我想实现的是 点击下方某一个搜索引擎时，搜索框左边的图标就会相应的转换成那个搜索引擎的logo
我原想着传search组件数组中的text数据到子组件searchBar来，但是报错了
请问该如何处理呢？请赐教，不胜感激。
<template>
<div class="search-bar">
{{text}}
<div class="select-box">
<span class="search-logo"></span>
<i id="down" class="el-icon-caret-bottom" @click="putList"></i>
</div>
<input type="text" v-model="inputText" @change="toSearch(inputText)"
placeholder="输入并搜索" />
</div>
</template>
<script>
export default {
data() {
return {
inputText:''
}
},
props:['text'],
methods: {
putList(){
var downlogo=document.getElementsById("down")
console.log(downlogo)
downlogo.className="el-icon-caret-up"
console.log(document.getElementsByClassName('el-icon-caret-up'))
},
toSearch(text){
console.log("输入搜索框的内容：",text)
this.$emit("inputTxt",text)
}
},
}
</script>

}
.search-bar input{

上为searchbar组件，即搜索框
下为search组件，即放置搜索引擎的地方

html5
父组件向子组件传递text值：
父组件：<searchBar :text="text"/>
子组件接收：props: ["text"]
--
要在search中定义一个text，当click时修改这个text值。
然后在<searchBar :text="text"/>，传递给子组件，子组件就能接收到这个text值了
