el-autocomplete 的使用

<el-form-item label="項目選擇" prop="projectReimbursement.projectId"  :verify="['NotNull']">
  <el-autocomplete
    clearable
    class="inline-input"
    v-model="detailForm.projectReimbursement.projectName"
    :fetch-suggestions="querySearch"
    value-key="projectName"
    placeholder="請輸入項目"
    @select="handleSelect"
  ></el-autocomplete>
</el-form-item>

querySearch(queryString, cb) {
  var restaurants = this.projectOptions;
  var results = queryString ? restaurants.filter(this.createFilter(queryString)) : restaurants;
  // 調用 callback 返回建議列表的數據
  cb(results);
},
createFilter(queryString) {
  return (restaurant) => {
    return (restaurant.projectName.indexOf(queryString.toLowerCase()) === 0);
  };
},
handleSelect(item) {
  this.detailForm.projectReimbursement.projectId = item.id;
  console.log(item);
},

value-key=“projectName” 輸入建議對象中用於顯示的鍵名
return (restaurant.projectName.indexOf(queryString.toLowerCase()) === 0); 用來比對的值，符合條件的篩選出來

@select=“handleSelect” 當前選中的那一項 可在事件裏進行操作 獲取當前項的id等
