在Angular 7中实现动态HTML Bootstrap表的排序和过滤的最佳方式是使用Angular的内置功能和第三方库ngx-bootstrap。
首先,确保已经安装了ngx-bootstrap库。可以通过以下命令进行安装:
npm install ngx-bootstrap --save
接下来,按照以下步骤实现动态HTML Bootstrap表的排序和过滤:
import { Component } from '@angular/core';
import { BsDropdownModule } from 'ngx-bootstrap/dropdown';
import { SortableModule } from 'ngx-bootstrap/sortable';
@Component({
selector: 'app-table',
templateUrl: './table.component.html',
styleUrls: ['./table.component.css']
})
export class TableComponent {
tableData: any[] = [
{ name: 'John', age: 25, city: 'New York' },
{ name: 'Jane', age: 30, city: 'London' },
{ name: 'Bob', age: 35, city: 'Paris' }
];
sortKey: string = '';
sortReverse: boolean = false;
filterText: string = '';
}
<table class="table">
<thead>
<tr>
<th (click)="sort('name')">Name</th>
<th (click)="sort('age')">Age</th>
<th (click)="sort('city')">City</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let item of tableData | filter: filterText | orderBy: sortKey: sortReverse">
<td>{{ item.name }}</td>
<td>{{ item.age }}</td>
<td>{{ item.city }}</td>
</tr>
</tbody>
</table>
<input type="text" [(ngModel)]="filterText" placeholder="Filter">
sort(key: string) {
this.sortKey = key;
this.sortReverse = !this.sortReverse;
}
import { Pipe, PipeTransform } from '@angular/core';
@Pipe({
name: 'filter'
})
export class FilterPipe implements PipeTransform {
transform(items: any[], searchText: string): any[] {
if (!items) return [];
if (!searchText) return items;
searchText = searchText.toLowerCase();
return items.filter(item => {
return Object.keys(item).some(key => {
return item[key].toString().toLowerCase().includes(searchText);
});
});
}
}
@Pipe({
name: 'orderBy'
})
export class OrderByPipe implements PipeTransform {
transform(items: any[], key: string, reverse: boolean): any[] {
if (!items) return [];
if (!key) return items;
return items.sort((a, b) => {
let x = a[key];
let y = b[key];
if (typeof x === 'string') {
x = x.toLowerCase();
}
if (typeof y === 'string') {
y = y.toLowerCase();
}
if (x < y) {
return reverse ? 1 : -1;
}
if (x > y) {
return reverse ? -1 : 1;
}
return 0;
});
}
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { TableComponent } from './table.component';
import { FilterPipe, OrderByPipe } from './custom-pipes';
@NgModule({
declarations: [
AppComponent,
TableComponent,
FilterPipe,
OrderByPipe
],
imports: [
BrowserModule,
FormsModule,
BsDropdownModule.forRoot(),
SortableModule.forRoot()
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
这样,你就可以在Angular 7中实现动态HTML Bootstrap表的排序和过滤了。请注意,以上示例中的代码仅供参考,你可以根据自己的需求进行修改和扩展。如果你想了解更多关于ngx-bootstrap的信息,可以访问腾讯云的ngx-bootstrap产品介绍页面:ngx-bootstrap产品介绍。
