ion-datetime

Datetimes present a calendar interface and time wheel, making it easy for users to select dates and times. Datetimes are similar to the native input elements of datetime-local, however, Ionic Framework's Datetime component makes it easy to display the date and time in the preferred format, and manage the datetime values.

1. To use ion-datetime in an Ionic application, you can follow these steps:

Add the IonDatetime component in your HTML file:

 <ion-datetime displayFormat="MMM DD, YYYY" [(ngModel)]="myDate"></ion-datetime>

2. Here, displayFormat is the format in which the date will be displayed, and [(ngModel)] is used to bind the selected date to a variable in your component. In your component file, define the variable that will hold the selected date:

ngModelChange is an event that is emitted whenever the value of an Angular input element bound to ngModel changes. It does not provide any information about the time at which the change occurred.

To get the time of the change, you can use the Date object in JavaScript to create a new instance of the current time when the ngModelChange event is emitted. You can then use this instance to display the time of the change in the desired format.

<ion-header [translucent]="true">
  <ion-toolbar color="primary">
    <ion-title>
      ion-datetime
    </ion-title>
  </ion-toolbar>
</ion-header>
<ion-content [fullscreen>]="true>">
   <div style="margin-left: 16px;">
     <h2>{{getDate}}</h2>
     <h2>{{getTime}}</h2>
   </div>
  <ion-datetime displayFormat="MMM DD, YYYY" (ngModelChange)="getValue($event)" [(ngModel)]="myDate"></ion-datetime>
</ion-content>

In Angular, you can remove text from a string using various methods, including:

1. Using the built-in replace() function:

The replace() function can be used to replace a substring with another substring or an empty string. Here's an example:

The date look like (2023-05-11T16:35:00)

In this example, we used the replace() function to remove the word "T" from the original string.

1. Using the replace() function:

The substring() function can be used to extract a part of a string. Here's an example:

import { Component } from '@angular/core';

@Component({
  selector: 'app-home',
  templateUrl: 'home.page.html',
  styleUrls: ['home.page.scss'],
})
export class HomePage {
  myDate: any;
  getDate: any;
  getTime: any;
  
  constructor() {}

  getValue(even: any) {
    even = even.replace("T", "");
    this.getDate = even.substring(0, 10);
    this.getTime = even.substring(10, 15);
    console.log(this.getDate);
    console.log(this.getTime);
  }
  
}

In this example, we used a regular expression to remove all occurrences of the letter "T" from the string "2023-05-11T16:35:00" and replice date to get time and date.

These are just a few examples of how to remove text from a string in Angular. The method you choose will depend on the specific requirements of your application.

There are many other options and properties that you can use with ion-datetime, such as min and max dates, time picker, etc. You can refer to the official Ionic documentation for more details:
