Get value from input in Ionic 4 alert

manpreet Best Answer 3 years ago

As of today the Ionic 4 documentation on ion-alert contains an example how to add a text input to an alert, like this:

const alert = await this.alertController.create({
  inputs: [
    {
      name: 'name1',
      type: 'text'
    },

But I can not find out how to access the value from the name1 text input, for example in the button handlers.

Do I have to use something like document.getElementById or is there a more Ionic/Angular-style way?

you can have a button that on the close of the alert can handle the data.

  const alert = await this.alertController.create({
      inputs: [
        {
          name: 'name1',
          type: 'text'
        }],    
       buttons">buttons: [
            {
              text: 'Cancel',
              role: 'cancel',
              cssClass: 'secondary',
              handler: () => {
                console.log('Confirm Cancel');
              }
            }, {
              text: 'Ok',
              handler: () => {
                 alert.onDidDismiss().then((alertData)=>{
                 console.log(alertData.data.values.name1)
                 })
              }
            }
          ]
  });
