这篇文章主要介绍了Angular5中提取公共组件之radio list的实例代码，非常不错，具有一定的参考借鉴价值,需要的朋友可以参考下
本文给大家说一下Radio List的公共组件提取。
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 = new EventEmitter(); constructor() { } ngOnInit() { } changeSelected() { let data = { value: this.model, name: this.name }; this.onChange.emit(data); } } radio-list.component.html
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：
按照如上步骤，还缺少对应的selectChange($event):
selectChange(model: any) { this[model.name] = model.value; }总结
