    Tag标签 - 图1

    基本

    基本标签的用法，可以通过添加 nzMode="closeable" 变为可关闭标签。可关闭标签具有 nzOnClosenzAfterClose 两个事件。

    1. import { Component } from '@angular/core';
    3. @Component({
    4.   selector: 'nz-demo-tag-basic',
    5.   template: `
    6.     <nz-tag>Tag 1</nz-tag>
    7.     <nz-tag>
    8.       <a href="https://github.com/NG-ZORRO/ng-zorro-antd">Link</a>
    9.     </nz-tag>
    10.     <nz-tag nzMode="closeable" (nzOnClose)="onClose()" (nzAfterClose)="afterClose()">Tag 2</nz-tag>
    11.     <nz-tag nzMode="closeable" (nzOnClose)="preventDefault($event)">Prevent Default</nz-tag>
    12.   `,
    13.   styles: []
    14. })
    15. export class NzDemoTagBasicComponent {
    16.   onClose(): void {
    17.     console.log('tag was closed.');
    18.   }
    20.   afterClose(): void {
    21.     console.log('after tag closed');
    22.   }
    24.   preventDefault(e: Event): void {
    25.     e.preventDefault();
    26.     e.stopPropagation();
    27.     console.log('tag can not be closed.');
    28.   }
    29. }

    动态添加和删除

    用数组生成一组标签，可以动态添加和删除，通过监听删除动画结束的事件 nzAfterClose 实现。

    1. import { Component, ElementRef, ViewChild } from '@angular/core';
    3. @Component({
    4.   selector: 'nz-demo-tag-control',
    5.   template: `
    6.     <nz-tag
    7.       *ngFor="let tag of tags; let i = index"
    8.       [nzMode]="i === 0 ? 'default' : 'closeable'"
    9.       (nzAfterClose)="handleClose(tag)"
    10.     >
    11.       {{ sliceTagName(tag) }}
    12.     </nz-tag>
    13.     <nz-tag *ngIf="!inputVisible" class="editable-tag" nzNoAnimation (click)="showInput()">
    14.       <i nz-icon type="plus"></i> New Tag
    15.     </nz-tag>
    16.     <input
    17.       #inputElement
    18.       nz-input
    19.       nzSize="small"
    20.       *ngIf="inputVisible"
    21.       type="text"
    22.       [(ngModel)]="inputValue"
    23.       style="width: 78px;"
    24.       (blur)="handleInputConfirm()"
    25.       (keydown.enter)="handleInputConfirm()"
    26.     />
    27.   `,
    28.   styles: [
    29.     `
    30.       .editable-tag {
    31.         background: rgb(255, 255, 255);
    32.         border-style: dashed;
    33.       }
    34.     `
    35.   ]
    36. })
    37. export class NzDemoTagControlComponent {
    38.   tags = ['Unremovable', 'Tag 2', 'Tag 3'];
    39.   inputVisible = false;
    40.   inputValue = '';
    41.   @ViewChild('inputElement') inputElement: ElementRef;
    43.   handleClose(removedTag: {}): void {
    44.     this.tags = this.tags.filter(tag => tag !== removedTag);
    45.   }
    47.   sliceTagName(tag: string): string {
    48.     const isLongTag = tag.length > 20;
    49.     return isLongTag ? `${tag.slice(0, 20)}...` : tag;
    50.   }
    52.   showInput(): void {
    53.     this.inputVisible = true;
    54.     setTimeout(() => {
    55.       this.inputElement.nativeElement.focus();
    56.     }, 10);
    57.   }
    59.   handleInputConfirm(): void {
    60.     if (this.inputValue && this.tags.indexOf(this.inputValue) === -1) {
    61.       this.tags = [...this.tags, this.inputValue];
    62.     }
    63.     this.inputValue = '';
    64.     this.inputVisible = false;
    65.   }
    66. }
