If you need to create an input for:
- credit card
- phone number
- date
- birthday
- numbers
- Or other custom mask
This project could help you in all this situations!
Take a look at our demos: https://codesandbox.io/s/svelte-input-mask-demo-xurgr
Install it:
npm install --save svelte-input-mask or if you're using yarn:
yarn add svelte-input-mask Import MaskInput component:
import MaskInput from "svelte-input-mask/MaskInput.svelte";Use it (for example for CreditCard):
<MaskInput alwaysShowMask maskChar="_" mask="0000-000000-00000" />Add event listeners:
<script> import MaskInput from 'svelte-input-mask/MaskInput.svelte'; let mask = '0000-0000-0000-0000'; const handleChange = ({ detail }) => { console.log(detail.inputState.maskedValue); // stores the value of input if (detail.inputState.maskedValue.indexOf('34') === 0 || detail.inputState.maskedValue.indexOf('37') === 0) { mask = '0000-000000-00000'; return; } mask = '0000-0000-0000-0000'; }; </script> <MaskInput alwaysShowMask maskChar="_" {mask} on:change={handleChange} />Congrats! You made the first masked input :)

Credit cards:
<MaskInput alwaysShowMask maskChar="_" mask="0000-000000-00000" />Phones (you still can change prefixes, country code like in credit card example):
<MaskInput alwaysShowMask mask="+1 (000) 000 - 0000" size={20} showMask maskChar="_" />Dates:
<script> import MaskInput from 'svelte-input-mask/MaskInput.svelte'; let maskString = 'DD.MM.YYYY'; let mask = '00.00.0000'; const handleChange = ({ detail }) => { const value = detail.inputState.maskedValue; if (parseInt(value[6], 10) > 2) { maskString = 'DD.MM.YY'; mask = '00.00.00'; } else { maskString = 'DD.MM.YYYY'; mask = '00.00.0000'; } }; </script> <MaskInput alwaysShowMask {maskString} {mask} on:change={handleChange}/>Numbers:
<script> import NumberInput from 'svelte-input-mask/NumberInput.svelte'; </script> <NumberInput />Mask input has next props:
| Prop | Default value | Description |
|---|---|---|
| value | - | The value of the input. Will be processed to masked one. In this case you can control the value of the component |
| defaultValue | - | The default value of the input. Will be applied only during the first render |
| maskString | - | The mask string to show if there are no filled chars. It's length should be the same as mask. Example: 'DD.MM.YYYY' |
| maskChar | '' | In case you don't need a custom string you can define only a definite char for mask. Example: maskChar = '_' and mask = '0000-0000-0000-0000' will give: ____-____-____-____ |
| mask | - | The mask of the input. Could be a credit card: '0000-0000-0000-0000', date: 00.00.0000 or whatever you want :) Doesn't work if reformat prop is setted |
| maskFormat | regexp | The regexp for custom formatting. You may use it if you want to define a specific mask. See example here: https://github.com/xnimorz/masked-input/blob/master/packages/input-core/src/index.ts#L16-L28 |
| alwaysShowMask | false | Flag to show the mask |
| showMask | false | Show mask if there is any data in input |
| reformat | - | The function, which defines a custom formatting rules. In case if you can't describe the format only with mask (e.g. numbers). If you use this prop mask prop will be ignored |
Svelte mask input pass all props that it doesn't handle right to input html element.
