Installing

$ npm install --save ngx-mask

Quickstart

Import ngx-mask module in Angular app.

import {NgxMaskModule} from 'ngx-mask'

(...)

@NgModule({
  (...)
  imports: [
    NgxMaskModule.forRoot(options)
  ]
  (...)
})

Then, just define masks in inputs.

Usage

<input type='text' mask='{here comes your mask}' >

Also you can use mask pipe

Usage

<span>{{phone | mask: '(000) 000-0000'}}</span>

Examples

mask	example
9999-99-99	2017-04-15
0*.00	2017.22
000.000.000-99	048.457.987-98
AAAA	0F6g
SSSS	asDF

Mask Options

You can define your custom options for all directives (as object in the mask module) or for each (as attributes for directive). If you override this parameter, you have to provide all the special characters (default one are not included).

specialCharacters (string[ ])

We have next default characters:

character
/
(
)
.
:
-
space
+
,
@

Usage

<input type='text' [specialCharacters]="[ '[' ,']' , '\\' ]" mask="[00]\[000]" >

Then:

Input value: 789-874.98
Masked value: [78]\[987]

### patterns ({ [character: string]: { pattern: RegExp, optional?: boolean})

We have next default patterns:

code	meaning
0	digits (like 0 to 9 numbers)
9	digits (like 0 to 9 numbers), but optional
A	letters (uppercase or lowercase) and digits
S	only letters (uppercase or lowercase)

Usage:

<input type='text' [patterns]="customPatterns" mask="(000-000)" >

and in your component

public customPatterns = {'0': { pattern: new RegExp('\[a-zA-Z\]')}};

Then:

Input value: 789HelloWorld
Masked value: (Hel-loW)

prefix (string)

You can add prefix to you masked value

Usage

<input type='text' prefix="+7 " mask="(000) 000 00 00" >

sufix (string)

You can add sufix to you masked value

Usage

<input type='text' sufix=" $" mask="0000" >

dropSpecialCharacters (boolean)

You can choose if mask will drop special character in the model, or not, default value true

Usage

<input type='text' [dropSpecialCharacters]="false" mask="000-000.00" >

Then:

Input value: 789-874.98
Model value: 789-874.98

showMaskTyped (boolean)

You can choose if mask is shown while typing, or not, default value false

Usage

 <input mask="(000) 000-0000" prefix="+7" [showMaskTyped] = "true">

clearIfNotMatch (boolean)

You can choose clear the input if the input value not match the mask, default value false

Pipe with mask expression and custom Pattern ([string, pattern])

You can pass array of expression and custom Pattern to pipe

Usage

 <span>{{phone | mask: customMaska}}</span>

and in your component

customMaska: [string, pattern];

pattern =  {
    'P': {
        pattern: new RegExp('\\d'),
    }};
  
this.customMaska = ['PPP-PPP', this.pattern];

Repeat mask

You can pass into mask pattern with brackets

Usage

 <input type='text' mask="A{4}">

Thousand separator

You can devide your input by thousands

Usage

 <input type='text' mask="separator">

For separate input with dots

 <input type='text' mask="dot_separator">

For using decimals enter '.' to the end of your input to 'separator' mask and ',' to 'dot_separator'

 <input type='text' mask="comma_separator">

For using decimals enter '.' to the end of your input to 'separator' or 'comma_separator' mask and ',' to 'dot_separator'

Input value: 1234.56
Masked value: 1 234.56

Input value: 1234,56
Masked value: 1.234,56

Input value: 1234.56
Masked value: 1,234.56

 <input type='text' mask="dot_separator.2">
 <input type='text' mask="comma_separator.2">
 <input type='text' mask="dot_separator.0">
 <input type='text' mask="comma_separator.0">

For limiting decimal precision add '.' and the precision you want to limit too on the input. 2 is useful for currency. 0 will prevent decimals completely.

Input value: 1234,56
Masked value: 1.234,56

Input value: 1234.56
Masked value: 1,234.56

Input value: 1234,56
Masked value: 1.234

Input value: 1234.56
Masked value: 1,234

 <input type='text' mask="percent" sufix="%">

FormControl validation

            symbol: 'X'
