在 Ionic 上单击警告框外部时如何不关闭警告框
How to not dismiss the alert box when clicking outside of it on Ionic
我正在构建一个 ionic 2 应用程序,我正在使用以下组件
http://ionicframework.com/docs/components/#alert
import { AlertController } from 'ionic-angular';
export class MyPage {
constructor(public alertCtrl: AlertController) {
}
showAlert() {
let alert = this.alertCtrl.create({
title: 'New Friend!',
subTitle: 'Your friend, Obi wan Kenobi, just accepted your friend request!',
buttons: ['OK']
});
alert.present();
}
}
如何确保当我在框外单击时不会关闭警报?
在 alertCtrl.create 选项中设置 enableBackdropDismiss: false
离子 2/3:
如您在 the AlertController docs 中所见,您可以在创建警报时使用 enableBackdropDismiss
(布尔值)选项:
enableBackdropDismiss: Whether the alert should be dismissed by tapping the backdrop. Default
true
import { AlertController } from 'ionic-angular';
// ...
export class MyPage {
constructor(public alertCtrl: AlertController) {}
showAlert() {
let alert = this.alertCtrl.create({
title: 'New Friend!',
subTitle: 'Your friend, Obi wan Kenobi, just accepted your friend request!',
buttons: ['OK'],
enableBackdropDismiss: false // <- Here! :)
});
alert.present();
}
}
离子 4/5:
在 Ionic 4/5 中 this property 已重命名为 backdropDismiss
:
backdropDismiss: If true, the alert will be dismissed when the backdrop is clicked.
import { AlertController } from '@ionic/angular';
//...
export class MyPage {
constructor(public alertController: AlertController) {}
async showAlert() {
const alert = await this.alertController.create({
header: 'Alert',
subHeader: 'Subtitle',
message: 'This is an alert message.',
buttons: ['OK'],
backdropDismiss: false // <- Here! :)
});
await alert.present();
}
}
在 ionic 4 中,该选项已重命名为
backdropDismiss: false
