Radio List组件提取起来很方便，不想Checkbox那么复杂。
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"> <div *ngFor="let item of list"> <div> <input type="radio" [value]="item.id" [(ngModel)]="model" (change)="changeSelected()"> <label for="{{name}}_{{item.id}}"> {{item.name}} </label> </div> </div> </div>
在相关引用的module中注册
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; }
对应的html中引用如下：
<app-radio-list [list]="sourceArr" [name]="'selectedSource'" [colNum]="12" [(selectModel)]="selectedSource" (selectChange)="selectChange($event)"> </app-radio-list>
按照如上步骤，还缺少对应的selectChange($event):
selectChange(model: any) { this[model.name] = model.value; }
总结
以上所述是小编给大家介绍的Angular5中提取公共组件之radio list的实例代码，希望对大家有所帮助，如果大家有任何疑问请给我留言，小编会及时回复大家的。在此也非常感谢大家对脚本之家网站的支持！
