基本用法

最简单的用法。

import { Component } from '@angular/core';
@Component({
  selector: 'demo-radio-basic',
  template: `
    <div>
      <List [renderHeader]="renderHeader">
        <RadioItemGroup [(ngModel)]="selectedStatus1.value" (onChange)="onChange($event)">
          <RadioItem *ngFor="let i of data" [name]="i.name" [value]="i.value">
            {{ i.name }}
          </RadioItem>
        </RadioItemGroup>
      </List>
      <WhiteSpace [size]="'lg'"></WhiteSpace>
      <List>
        <RadioItemGroup [(ngModel)]="selectedStatus2.value" (onChange)="onChange2($event)">
          <RadioItem *ngFor="let i of data2" [name]="i.name" [value]="i.value">
            {{ i.name }}
            <Brief>{{ i.extra }}</Brief>
          </RadioItem>
        </RadioItemGroup>
      </List>
      <List [renderHeader]="renderHeader2">

  `,
  styles: [

  }
  onChange3 = e => {
    this.disabled = false;
    console.log('agree submit', e);

API

Radio

RadioItemGroup

单选框组合，包裹一组RadioItems。

RadioItem

基于ListItem对Radio进行封装,ListItem的extra属性固定传入Radio,其他属性和ListItem一致(除了onClick回调事件不可用之外，因为在这里是由RadioItemGroup传递回调事件)。
