Can you provide me with the round-the-clock regular expressions for the 'angular2-input-mask' plugin?

Need assistance with inputting 24-hour time format using 'angular2-input-mask'. Currently using the following mask. What is the correct mask for a valid 24-hour time format?

 this.mask = [/[0-2]/, /^([0-9]|2[0-3])/, ':', /[0-5]/, /[0-9]/];

Answer №1

Here is the proper way to implement a mask for the hour using angular2-input-mask

HTML:

<input type="text" (keyup)="setTime($event)" [(value)]="timeStr" [textMask]="getMask()" />

TypeScript:

Set the time on key up

setTime(e):void{
  this.time = e.target.value;
}

Define the mask based on this.time

getMask():{
  mask: Array<string | RegExp>;
  keepCharPositions: boolean;
} {
  return {
    mask: [/[0-2]/, this.time && parseInt(this.time[0]) > 1 ? /[0-3]/ : /\d/, ':', /[0-5]/, /\d/],
    keepCharPositions: true
  };
}

Answer №2

At last, I was able to find a solution to my issue using this method.

HTML

 <input [textMask]="{mask: mask}" [(ngModel)]="input_time" (ngModelChange)=changeRegex(input_time);type="text"/>

TypeScript

Implement this code snippet in your Angular 2 component.

 public mask: Array<string | RegExp> = [/[0-2]/,/\d/, ':', /[0-5]/, /\d/],

 changeRegex(input_time){
    if(input_time.charAt(0) == '2'){
       this.mask[1]=new RegExp('[0-3]')
    }else{
       this.mask[1]=new RegExp('\d')
    }
  }
