Angular 2 radio button events
It works,
<input type="radio" (change)="handleChange($event)" />But you need code more to judge 'selected' or 'unselected'.
You may try this in your *.ts file:
export class Comp { private _prevSelected: any; handleChange(evt) { var target = evt.target; if (target.checked) { doSelected(target); this._prevSelected = target; } else { doUnSelected(this._prevSelected) } } }
It works when you assign the click event to the label, instead of the input.
The html is like
<div *ngFor = " let displayParameter of displayParameters" > <!-- <li><a href="#">{{displayParameter}}</a></li> --> <!-- <input type="radio" name="displayParameter" (change) ="handleChange(event)")> --> <h5><input type="radio" name="radiogroup" (change)="handleChange(displayParameter)" [checked]="(idx === 0)" >{{displayParameter}} </h5></div>and code is like
handleChange(evt){ this.displayParameter = evt; console.log(evt); }
