🐞 bug report

Is this a regression?

Yes, the behaviour was correct in version 15.0.0 but is broken in version 15.2.3 (or somewhere in between).

Description

On the Stackblitz example below, enter the value 15-02-2024 in the input. Afterwards try to clear the value using the backspace. The expected result would be an empty input. However, the library seems to add a few zero's instead. This is most probably caused by the leadZeroDateTime property. When setting leadZeroDateTime to false, this issue does not occur (but will obviously result in different behaviour)

🔥 Exception or Error

No errors are logged in the console.

🌍 Your Environment

Angular Version:


"dependencies": {
    "@angular/animations": "^15.1.1",
    "@angular/cdk": "^15.1.1",
    "@angular/cdk-experimental": "^15.1.1",
    "@angular/common": "^15.1.1",
    "@angular/compiler": "^15.1.1",
    "@angular/core": "^15.1.1",
    "@angular/forms": "^15.1.1",
    "@angular/platform-browser": "^15.1.1",
    "@angular/platform-browser-dynamic": "^15.1.1",
    "@angular/router": "^15.1.1",
    "ngx-mask": "15.2.3",
    "rxjs": "^7.8.0",
    "tslib": "^2.4.1",
    "zone.js": "^0.12.0"
  }

Anything else relevant? As a workaround, the user can select the entire text and the use delete or backspace to clear the input. However, we don't expect that every user knows this. So hopefully this will be fixed in a future release. For other newer version, I did not test this so I can't say if for example the issue also occurs in version 16.x

update: I tried the same config in an Angular 16 and 17 demo app using the respective version of ngx-mask and the same behaviour is also noticeable. So it seem it is not specifically tied to version 15.x of the library.

JsDaddy / ngx-mask

ngx-mask appends zero's when using a date mask in combination with leadZeroDateTime=true #1307
