我想寫一個模式與離子形式。出於某種原因,任何時候我將ngModel
與<ion-checkbox>
(或<ion-radio>
)關聯在一起,我的模態就不會顯示出來(構造函數被調用)。ngModel問題與離子複選框
我的控制器:
import { Component } from '@angular/core';
import { NavController, NavParams, ViewController } from 'ionic-angular';
@Component({
selector: 'page-alert-modal',
templateUrl: 'alert-modal.html',
})
export class AlertModalPage {
formData = {};
constructor(public navCtrl: NavController, public navParams: NavParams, viewCtrl:ViewController) {
//this.formData = {xy:"", name:"", obd:""};
console.log ("*** Modal constructor");
}
logForm() {
console.log ("Submitted")
}
我的模板:
<ion-content padding>
<form (ngSubmit)="logForm()">
<ion-list-header>Trip Details</ion-list-header>
<ion-item>
<ion-label floating>Name your trip:</ion-label>
<ion-input [(ngModel)]="formData.name" name="tripname"></ion-input>
</ion-item>
<ion-item>
<ion-label>Track GPS lat/long</ion-label>
<!-- if I enable the line below, the modal does not show up -->
<!--<ion-checkbox [(ngModel)]="formData.xy"></ion-checkbox>-->
<ion-checkbox></ion-checkbox>
</ion-item>
<ion-item>
<ion-label>Read BLE OBD</ion-label>
<!-- if I enable the line below, the modal does not show up -->
<!--<ion-checkbox [(ngModel)]="formData.obd"></ion-checkbox>-->
<ion-checkbox></ion-checkbox>
</ion-item>
</form>
<button ion-button block outline>Ok</button>
</ion-content>
