【todo】Angular6问题记录：ngDefaultControl

radio组件中使用input，但在使用组件时，报错，

于是查到可以用ngDefaultControl解决：

但是有浏览器兼容问题，在谷歌的低版本和360浏览器上，点击radio毫无反应
组件代码：
radio.component.ts

import {Component, Input} from '@angular/core';
@Component({
  selector: 'radio',
  templateUrl: './radio.component.html',
  styleUrls: ['./radio.component.css']
})

export class RadioComponent {
  @Input() name: string;
  @Input() value: any;
  @Input() model: any;
}

radio.component.html

<div class="radio-box" [ngClass]="{'radio-active':value==model}">
  <input type="radio" name="{{name}}" value="{{value}}">
  <div class="radio-checked" *ngIf="value==model"></div>
</div>

radio.component.css

.radio-box {
  width: 20px;
  height: 20px;
  background: #fff;
  border: 1px solid #dfe3eb;
  border-radius: 50%;
  position: relative;
  padding: 0;
  display: inline-block;
}

.radio-box input {
  width: 20px;
  height: 20px;
  position: absolute;
  top: 0;
  left: 0;
  margin: 0;
  outline: none;
  opacity: 0;
  z-index: 1000;
}

.radio-active {

}

.radio-checked {
  background: #ff893e;
  width: 10px;
  height: 10px;
  position: absolute;
  z-index: 999;
  top: 5px;
  left: 5px;
  border-radius: 50%;
}
