注意的細節
基礎使用
fetch-suggestions 這個方法是去請求包含關鍵字的搜索功能，這裏注意返回結果裏面的列表對象屬性裏面要有一個value的屬性，這個才能顯示，聯想輸入內容。
select 方法是選擇了一個聯想輸入的具體數據的點擊事件
注意事項
按enter鍵進行搜索功能@keyup.enter.native="searchAssets(event是一個什麼東西，其實就是一個事件，代碼
if (event) {
event.target.blur();
this.$refs.autocomplete.close();
}
這個是爲了處理點擊enter使input輸入框失去焦點，還有一個作用就是，讓el-autocomplete 的聯想輸入框關閉。這個達到和百度搜索類似的效果。
