本文給大家說一下Radio List的公共組件提取。
目前創(chuàng)新互聯(lián)建站已為成百上千的企業(yè)提供了網(wǎng)站建設(shè)、域名、虛擬主機(jī)、網(wǎng)站托管、服務(wù)器托管、企業(yè)網(wǎng)站設(shè)計(jì)、回民網(wǎng)站維護(hù)等服務(wù),公司將堅(jiān)持客戶導(dǎo)向、應(yīng)用為本的策略,正道將秉承"和諧、參與、激情"的文化,與客戶和合作伙伴齊心協(xié)力一起成長(zhǎng),共同發(fā)展。
Radio List組件提取起來很方便,不想Checkbox那么復(fù)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= new EventEmitter (); constructor() { } ngOnInit() { } changeSelected() { let data = { value: this.model, name: this.name }; this.onChange.emit(data); } }
radio-list.component.html
在相關(guān)引用的module中注冊(cè)
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(duì)應(yīng)的html中引用如下:
按照如上步驟,還缺少對(duì)應(yīng)的selectChange($event):
selectChange(model: any) { this[model.name] = model.value; }
總結(jié)
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(shí)例代碼,希望對(duì)大家有所幫助,如果大家有任何疑問請(qǐng)給我留言,小編會(huì)及時(shí)回復(fù)大家的。在此也非常感謝大家對(duì)創(chuàng)新互聯(lián)網(wǎng)站的支持!
