本文給大家說一下Radio List的公共組件提取。
Radio List組件提取起來很方便,不想Checkbox那么復雜。
radio-list.component.ts
import { Component, OnInit, Input, Output, EventEmitter } from '@angular/core'; import { RadioItem } from '../../model/radio'; import { NgModel } from '@angular/forms'; @Component({ selector: 'app-radio-list', templateUrl: './radio-list.component.html', styleUrls: ['./radio-list.component.css'] }) export class RadioListComponent implements OnInit { @Input() list: RadioItem[]; @Input() name: string; @Input() colNum: number = 6; @Input("selectModel") model: string; @Output("selectChange") onChange: EventEmitter<any> = new EventEmitter<any>(); constructor() { } ngOnInit() { } changeSelected() { let data = { value: this.model, name: this.name }; this.onChange.emit(data); } }
radio-list.component.html
<div *ngIf="list" class="form-row"> <div class="col-{{colNum}} mb-2" *ngFor="let item of list"> <div class="form-check abc-radio abc-radio-primary"> <input class="form-check-input" type="radio" [value]="item.id" [(ngModel)]="model" (change)="changeSelected()" name="{{name}}" id="{{name}}_{{item.id}}"> <label class="form-check-label" for="{{name}}_{{item.id}}"> {{item.name}} </label> </div> </div> </div>
在相關引用的module中注冊
import { RadioListComponent } from '../components/radio-list/radio-list.component'; export const routes = [ { path: '', component: xxxComponent, pathMatch: 'full' } ]; @NgModule({ imports: [...], declarations: [... , RadioListComponent , ...], providers: [] }) export class xxxModule { static routes = routes; }
對應的html中引用如下:
<app-radio-list [list]="sourceArr" [name]="'selectedSource'" [colNum]="12" [(selectModel)]="selectedSource" (selectChange)="selectChange($event)"> </app-radio-list>
按照如上步驟,還缺少對應的selectChange($event):
selectChange(model: any) { this[model.name] = model.value; }
總結
以上所述是小編給大家介紹的Angular5中提取公共組件之radio list的實例代碼,希望對大家有所幫助,如果大家有任何疑問請給我留言,小編會及時回復大家的。在此也非常感謝大家對億速云網站的支持!
