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]/];
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]/];
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
};
}
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')
}
}
