How to extract only a part of the string in angular / javascript

Question

I am using time-picker to get the time :

<div class="timePicker-container" >
                        <md-time-picker
                        className="end-time"
                        enable-date="false"
                        (whenChange)="timeSelectionChanged($event)"
                        [disabled]="systemlogsform.value.range==='relativerange'">
                      </md-time-picker>
                      </div>

And timeSelectionChanged is as shown below:

  public timeSelectionChanged(momentTime) {
    console.log('momentTime', momentTime._d)
    }

This contains the below data:

Tue Jun 15 2021 00:17:32 GMT+0530 (India Standard Time)

Now , how will I be able to get only the time part , i.e. 00:17:32 ?

Do you want the time just to display or do you actually want to store it like that? If this is just formatting to display, use the built in date pipe — Conner Enders

You can convert into Date format and get hours , minutes and seconds from there.

getOnlyTime(dateTimeFormat)
{
  let newFormat = new Date(dateTimeFormat);
  let hr = newFormat .getHours(); 
  let mins = newFormat .getMinutes(); 
  let secs = newFormat .getSeconds(); 

  let timeOnly = hr + ":" + mins + ":" + secs;
  return timeOnly;
 }

You can call the method to retrieve the time.

let timeFormat = getOnlyTime(momentTime._d);
console.log(timeFormat);

I am not sure what package you are using to convert into the required format, but if you are using 'moment.js' package, you can take a look at this website

Link to moment.js ==> https://momentjs.com/

What you want to do is something like this:

var myDate = "2017-08-30T14:24:03";
console.log(moment(myDate).format("HH:mm")); // 24 hour format
console.log(moment(myDate).format("hh:mm")); // 12 hour format
console.log(moment(myDate).format("hh:mm a")); // use 'A' for uppercase AM/PM
console.log(moment(myDate).format("hh:mm:ss A")); // with milliseconds

const dt = "Tue Jun 15 2021 00:17:32 GMT+0530 (India Standard Time)"

const d = new Date(dt).toLocaleTimeString(undefined, {
  timeZone: 'Asia/Kolkata'
})
console.log(d)
