首先需要安装 amap-jsapi-loader 和 vue3-autocomplete 插件:
```
npm install amap-jsapi-loader vue3-autocomplete
```
然后在需要使用搜索功能的组件中,引入 amap-jsapi-loader 和 vue3-autocomplete:
```vue
<template>
<div>
<el-autocomplete
v-model="searchValue"
:fetch-suggestions="querySearchAsync"
placeholder="请输入关键词进行搜索"
:trigger-on-focus="false"
:custom-item="renderSuggestion"
></el-autocomplete>
</div>
</template>
<script>
import { ref } from 'vue';
import { ElAutocomplete } from 'element-plus';
import { createAMapLoader } from 'amap-jsapi-loader';
import 'element-plus/packages/theme-chalk/src/base.scss';
import 'element-plus/packages/theme-chalk/src/autocomplete.scss';
export default {
setup() {
const searchValue = ref('');
const suggestions = ref([]);
const querySearchAsync = async (query) => {
const AMap = await createAMapLoader({
key: '你的高德地图 API KEY',
version: '2.0',
});
const poiList = await AMap.plugin('AMap.PlaceSearch', () => {
const placeSearch = new AMap.PlaceSearch({
pageSize: 10,
pageIndex: 1,
city: '全国',
});
return new Promise((resolve, reject) => {
placeSearch.search(query, (status, result) => {
if (status === 'complete') {
resolve(result.poiList.pois);
} else {
reject(status);
}
});
});
});
suggestions.value = poiList.map((item) => ({
value: item.name,
address: item.address,
location: item.location,
}));
};
const renderSuggestion = ({ item }) => {
return (
<div class="suggestion-item">
<div class="suggestion-item-name">{item.value}</div>
<div class="suggestion-item-address">{item.address}</div>
</div>
);
};
return {
searchValue,
querySearchAsync,
renderSuggestion,
};
},
components: {
ElAutocomplete,
},
};
</script>
<style scoped>
.suggestion-item {
display: flex;
flex-direction: column;
}
.suggestion-item-name {
font-weight: bold;
}
.suggestion-item-address {
font-size: 12px;
color: #999;
}
</style>
```
在这个例子中,我们使用了 createAMapLoader 方法来异步加载高德地图 API,然后使用 PlaceSearch 类搜索关键词,并将搜索结果转换为 ElAutocomplete 组件可以使用的格式。最后,我们使用 renderSuggestion 方法来自定义搜索结果的渲染方式。
需要注意的是,在使用 amap-jsapi-loader 加载高德地图 API 的时候,需要传入你的高德地图 API KEY。如果没有的话,可以去高德地图开发者中心申请一个。
