I receive the following error when I try to use Radio buttons in ionic2
Error: Error at
/Users/xyz/something/.tmp/pages/new-group/new-group-frequency.ngfactory.ts:528:29
[16:10:25] Supplied parameters do not match any signature of call target.
[16:10:25] ngc failed
[16:10:25] ionic-app-script task: "build"
My template looks like below:
<ion-content padding>
<form (submit)="onSubmit($event)" [formGroup]="myForm">
<ion-list radio-group formControlName="langs">
<ion-item>
<ion-label>Go</ion-label>
<ion-radio value="golang" checked="true"></ion-radio>
</ion-item>
</ion-list>
</form>
</ion-content>
The associated typescript file:
import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { FormGroup, FormControl } from '@angular/forms';
@Component({
selector: 'new-group-frequency',
templateUrl: 'new-group-frequency.html'
})
export class NewGroupFrequency {
myForm: FormGroup;
constructor(public _nav:NavController) {
this.myForm = new FormGroup({
"langs": new FormControl('')
});
}
onSubmit() {}
}
Can't figure out what the issue is
我唯一看到的是,当您调用(submit)="onSubmit($event)"
您正在发送一个参数,但是在方法的声明onSubmit() {}
您并未声明事件参数。
