Changing the time format to ISO in order to fill the ion-datetime component within Ionic 2

Question

Changing the time format to ISO in order to fill the ion-datetime component within Ionic 2

I have this snippet of code in my HTML file:

<ion-datetime [(ngModel)]="time" formControlName="time" displayFormat="hh:mm a"></ion-datetime>

I am trying to populate the ion datetime element with data retrieved from the server. The response from the HTTP request is in string format as follows:

10:00PM

In my TypeScript file, I am using the following code to fill the ion datetime element:

this.time = data.time;

Where data.time = '10:00PM'

Unfortunately, I keep getting an error that says "invalid ISO Format."

Can someone assist me with converting the time format '10:00PM' to ISO format so I can successfully populate the ion datetime element with the display format of 'hh:mm a'?

Your help is greatly appreciated. Thank you :)

Answer №1

To display '10:00PM', you must first convert the string to '22:00'. By using this format, the ion-datetime component will automatically select '10:00' as the hour and 'PM'.

This conversion can be easily achieved with moment.js, like so:

moment(yourString, 'h:mm a').format('H:mm');

Afterwards, as you suggested, update the displayFormat attribute to reflect the desired format as shown below:

<ion-item no-padding color="light">
  <ion-label floating>{{ 'FIELDS.TIME' | translate }}</ion-label>
  <ion-datetime ... displayFormat="hh:mm A"></ion-datetime>
</ion-item>
