Angular封装搜索框组件操作示例

这篇文章主要介绍了Angular封装搜索框组件操作,结合实例形式分析了基于Angular组件库实现搜索功能的封装操作相关实现步骤与注意事项,需要的朋友可以参考下

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。
