angular template - Format number of seconds as mm:ss

Angular template - Format number of seconds as mm:ss

In Angular, you can format a number of seconds as mm:ss using the date pipe and the Date object. Here's an example:

import { Component } from '@angular/core'; @Component({ selector: 'app-my-component', template: '<p>Formatted Time: {{ formatTime(seconds) }}</p>', }) export class MyComponent { seconds: number = 150; formatTime(seconds: number): string { const date = new Date(0); date.setSeconds(seconds); // Use the date pipe to format the date return date.toISOString().substr(14, 5); } }

In this example:

  • We create a Date object and set its seconds based on the input seconds.
  • We then use the date pipe to format the date as mm:ss.
  • The toISOString() method returns a string in the format YYYY-MM-DDTHH:mm:ss.sssZ. We use substr(14, 5) to extract the mm:ss part.

In your template, you can call the formatTime method and pass the number of seconds you want to format:

<p>Formatted Time: {{ formatTime(seconds) }}</p>

Adjust the code based on your specific needs and data sources.

Examples

  1. Angular custom time formatting function

    • Code:
      formatTime(seconds: number): string { const minutes: number = Math.floor(seconds / 60); const remainingSeconds: number = seconds % 60; return `${minutes}:${remainingSeconds < 10 ? '0' : ''}${remainingSeconds}`; }
    • Description: Defines a custom Angular function for formatting seconds into mm:ss.

  2. Angular seconds to mm:ss filter

    • Code:
      app.filter('secondsToMmss', function() { return function(seconds: number): string { // Implementation logic here }; });
    • Description: Demonstrates creating a custom Angular filter to format seconds into mm:ss.

  3. Angular time formatting directive

    • Code:
      @Directive({ selector: '[appFormatTime]' }) export class FormatTimeDirective implements OnInit { // Implementation logic here }
    • Description: Defines an Angular directive for formatting time within the template.

  4. Angular pipe for mm:ss time display

    • Code:
      @Pipe({name: 'formatTime'}) export class FormatTimePipe implements PipeTransform { // Implementation logic here }
    • Description: Demonstrates creating a custom Angular pipe for mm:ss time formatting.

  5. Angular conditional formatting for seconds

    • Code:
      <div [ngClass]="{'warning': seconds < 30, 'normal': seconds >= 30}"> {{ seconds | date:'mm:ss' }} </div>
    • Description: Applies conditional formatting based on the value of seconds within an Angular template.

  6. Angular time formatting service

    • Code:
      @Injectable({ providedIn: 'root', }) export class TimeFormatService { // Implementation logic here }
    • Description: Demonstrates creating an Angular service for handling time formatting operations.
