Angular封装搜索框组件操作示例

本文实例讲述了Angular封装搜索框组件操作。分享给大家供大家参考,具体如下:

后台管理系统多是以表格和表单为主,有列表就一定会有列表的筛选功能,所以在此把列表头部的搜索功能拆分出一个公共组件,方便使用。

大致样式如下图:

这里我使用的是ng-zorro蚂蚁金服的angular组件库

index.html:

{{item.label}} {{expandForm ? '收起' : '展开'}}

index.ts:

import { OnInit, Input, Output, Component, EventEmitter } from '@angular/core';
import { _HttpClient } from '@delon/theme';
@Component({
 selector: 'search-filter',
 templateUrl: './index.html',
 styleUrls: ['./index.less']
})
export class SearchFilterComponent implements OnInit {
 @Input() columns;
 @Input() loading;
 @Output() toSearch = new EventEmitter();
 constructor(
  private httpClient: _HttpClient,
 ) { }
 searchData: any = {
  page: 1,
  limit: 15
 };
 filterLength = 0;
 operatorOptions = [];
 merchantOptions = [];
 clientOptions = [];
 adminOptions = [];
 ngOnInit() {
  this.columns.forEach(el => {
   if (el.type == 'operator') {
    this.searchData['user_id'] = '';
    this.searchData['el.user_type'] = '';
    this.onSearch('')
   }
   if (el.type == 'merchant') {
    this.onSearch_merchant('')
   }
   if (el.type == 'client') {
    this.onSearch_client('')
   }
   if (el.type == 'admin') {
    this.onSearch_admin('')
   }
   this.searchData[el.key] = "";
   this.filterLength++;
  })
 }
 // 清空搜索条件
 resetData() {
  for (const i in this.searchData) {
   if (this.searchData[i]) {
    this.searchData[i] = '';
   }
  }
  this.searchData.page = 1;
  this.searchData.limit = 15;
  this.submit();
 }
 // 搜索按钮事件
 submit() {
  if (this.searchData.operator) {
   delete this.searchData.operator;
  }
  if (this.searchData.start_at) {
   this.searchData.start_at = this.format(this.searchData.start_at)
  }
  if (this.searchData.end_at) {
   this.searchData.end_at = this.format(this.searchData.end_at)
  }
  this.toSearch.emit(this.searchData);
 }
 // 日志操作人搜索
 onSearch(value: string) {
  this.httpClient.get('/api/admin/member?name=' + value).subscribe((res: {}) => {
   const resData: any = res;
   this.operatorOptions = resData.message;
  });
 }
 changeOption(value: {}) {
  this.searchData.user_id = value['id'];
  this.searchData.user_type = value['user_type'];
 }
 // 商户名称搜索
 onSearch_merchant(value: string) {
  this.httpClient.get('/api/admin/merchant?name=' + value).subscribe((res: {}) => {
   const resData: any = res;
   this.merchantOptions = resData.message.data;
  });
 }
 // 客户名搜索
 onSearch_client(value: string) {
  this.httpClient.get('/api/admin/user?name=' + value).subscribe((res: {}) => {
   const resData: any = res;
   this.clientOptions = resData.message.data;
  });
 }
 // 操作员名搜索
 onSearch_admin(value: string) {
  this.httpClient.get('/api/admin/admin?name=' + value).subscribe((res: {}) => {
   const resData: any = res;
   this.adminOptions = resData.message.data;
  });
 }
 // 格式化时间
 format(time) {
  var date = new Date(time);
  var year = date.getFullYear();
  var month = date.getMonth() + 1;
  var day = date.getDate();
  return (year + '-' + month + '-' + day);
 }
}



index.less:

:host {
  display: block;
  width: 95%;
  margin: 0 auto;
  ::ng-deep {
    nz-form-control {
      min-width: 60%;
    }
    nz-select {
      width: 100%;
    }
    .ant-calendar-picker {
      width: 100%;
    }
  }
}

其中有个特殊的地方,是根据用户输入的关键字,先模糊搜索用户名和用户类型,再根据用户选择的用户id去进行筛选。
