Usage

<input type="text" mask="<here goes your mask>" />
<input type="text" [mask]="<here goes a reference to your component's mask property>" />

Also, you can use mask pipe.

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

You could path any valid config options, for example thousandSeparator and suffix

<span>{{value | mask: 'separator': { thousandSeparator: ',', suffix: ' sm' } }}</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
UUUU ASDF
LLLL 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)
U only letters uppercase
L only letters 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)

Custom Pattern Definition for Input Masks

You can define a custom pattern and specify a unique symbol to be rendered in the input field.

Important Notes:

Reserved Characters: Certain characters (h, d, m, s) are reserved for date patterns and should not be used in custom patterns to avoid conflicts.

Special Symbol *: The * character is reserved for patterns like 0*, which means any length of digits
can appear before the asterisk. Avoid using this symbol in custom patterns.

<input type="text" mask="A*" />
pattern = {
    B: {
        pattern: new RegExp('\\d'),
        symbol: 'X',
    },
};

prefix (string)

You can add prefix to you masked value

Usage

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

instantPrefix

The input property instantPrefix controls the display behavior of a prefix in the input.

When set to true, the prefix is displayed even if the model is empty. When set to false, the prefix only becomes visible when a value is present in the model.

Usage

<input type="text" prefix="+7" instantPrefix="false" mask="(000) 000 00 00" />
<input type="text" prefix="+7" instantPrefix="true" mask="(000) 000 00 00" />

suffix (string)

You can add suffix to you masked value

Usage

<input type="text" suffix="$" mask="0000" />

dropSpecialCharacters (boolean | string[])

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

Usage

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

allowNegativeNumbers (boolean)

You can choose if mask will allow the use of negative numbers. The default value is false.

Usage

<input type="text" [allowNegativeNumbers]="true" mask="separator.2" />
Then
Input value: -10,000.45
Model value: -10000.45

placeHolderCharacter (string)

If the showMaskTyped parameter is enabled, this setting customizes the character used as placeholder. Default value is _.

Usage

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

clearIfNotMatch (boolean)

You can choose clear the input if the input value not match the mask, default value is 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: customMask}}</span>

and in your component

customMask: [string, pattern];

pattern = {
    P: {
        pattern: new RegExp('\\d'),
    },
};

this.customMask = ['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 divide your input by thousands, by default will seperate with a space.

Usage

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

For separate input with dots.

<input type="text" mask="separator" thousandSeparator="." />

For using decimals enter . and how many decimals to the end of your input to separator mask.

<input type="text" mask="separator.2" />
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="separator.2" thousandSeparator="." />
<input type="text" mask="separator.2" thousandSeparator="," />
<input type="text" mask="separator.0" thousandSeparator="." />
<input type="text" mask="separator.0" thousandSeparator="," />

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="separator.2" [leadZero]="true" />

To add zeros to the model at the end

Input value: 12
Masked value: 12.00

Input value: 12.1
Masked value: 12.10

<input type="text" mask="separator.2" separatorLimit="1000" />

For limiting the number of digits before the decimal point you can set separatorLimit value to 10, 100, 1000 etc.

Input value: 12345678,56
Masked value: 1.234,56
