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;
}
