Easy Number and Currency Formatting Library - autoNumeric

autoNumeric is a useful JavaScript library for international currency formatting as well as numbers formatting.

It supports almost all the major international numeric formats and currency signs used in Europe, North and South America, Asia and India.

You might also like:

How to use it:

1. Install & Import.

# Yarn
$ yarn add autonumeric

# NPM
$ npm install autonumeric --save
import AutoNumeric from 'autonumeric';

2. Or include the latest autoNumeric.js on the webpage

<script src="/path/to/autoNumeric.js"></script>
<!-- from a cdn -->
<script src="//unpkg.com/autonumeric"></script>

3. Create a normal input field on the page.

<form>
  <input type="text" class="demo">
</form>

4. Initialize the autoNumeric library and specify the currency symbol. Done.

new AutoNumeric('.demo', { currencySymbol : '$' });

5. All Options and defaults. You can also pass the following options via HTML5 data attributes.

/* Defines if the decimal places should be padded with zeroes
* `true`     : always pad decimals with zeros (ie. '12.3400')
* `false`    : never pad with zeros (ie. '12.34')
* `'floats'` : pad with zeroes only when there are decimals (ie. '12' and '12.3400')
* Note: setting allowDecimalPadding to 'false' will override the 'decimalPlaces' setting.
*/
allowDecimalPadding: {
  always: true,
  never : false,
  floats: 'floats',
},

/* Defines if the decimal character or decimal character alternative should be accepted when there is already a decimal character shown in the element.
* If set to `true`, any decimal character input will be accepted and will subsequently modify the decimal character position, as well as the `rawValue`.
* If set to `false`, the decimal character and its alternative key will be dropped as before. This is the default setting.
*/

  alwaysAllow: true,
  doNotAllow: false,

/* Defines where should be positioned the caret on focus
* null : Do not enforce any caret positioning on focus (this is needed when using `selectOnFocus`)
* `'start'` : put the caret of the far left side of the value (excluding the positive/negative sign and currency symbol, if any)
* `'end'` : put the caret of the far right side of the value (excluding the positive/negative sign and currency symbol, if any)
* `'decimalLeft'` : put the caret of the left of the decimal character if any
* `'decimalRight'` : put the caret of the right of the decimal character if any

v4.10.0 (2023-09-03)

  • Dropped IE11 support

v4.9.0 (2023-05-18)

  • This version modifies the AutoNumeric.options.digitalGroupSpacing.two option, which is now named AutoNumeric.options.digitalGroupSpacing.twoThree
  • The AutoNumeric.options.digitalGroupSpacing.two now effectively groups only by 2 (and not by 2 and 3 like before for India's numbering system)

v4.8.4 (2023-05-12)

  • Updates the function that search for form children to also include the contenteditable elements
  • All form functions relying on the _getFormAutoNumericChildren() function will now correctly include all inputs and contenteditable elements
  • Bugfix

v4.8.3 (2023-05-07)

  • Updates the yarn clean:log command to clean the logs from the newer webdriver.io version
  • Bugfixes

v4.8.2 (2023-04-04)

  • Avoid "Forced reflow" when calling the _historyTableAdd() function

v4.8.1 (2023-03-24)

  • Adds Feature: Disallow toggling the negative/positive sign with '+' and '-' keypress. This adds a new option negativePositiveSignBehavior for the managing the '-' and '+' key behavior
  • Updates the existing end-to-end tests that relied on the toggle behavior
  • Fixes the incorrect error message when setting an invalid positiveSignCharacter option
  • Attempts to fix the 'node: 18' error from Travis CI

  • Removes unused wdio script from package.json
  • By default the - and + key will not toggle the negative/positive state of an AutoNumeric element anymore.
  • The default behavior has changed in this version, where toggling between the positive and negative value with the '-' or '+' keys is not activated, instead - will try to set the value negative, and + will try to make it positive (this can fail if the resulting value is out of bounds).
  • If you want to use the previous behavior, please set negativePositiveSignBehavior: AutoNumeric.options.negativePositiveSignBehavior.toggle in your options' configuration.

v4.7.0 (2023-03-21)

  • Fixes Missing the \u0092 digit group separator
  • Fixes freezeOptions() can create issues in some browsers

v4.5.2 (2019-01-06)

  • Fixed: The autoNumeric:formatted event should be triggered when the input field is cleared while continuously pressing the Backspace or Deletekeys

v4.5.1 (2018-10-28)

  • Fixed: The html readonly attribute is ignored on initial load
  • Fix how readonly and disabled inputs should not process keyboard events
  • Fix the formula mode so that the custom decimal character set with decimalCharacter is used instead of the default '.' character when writing float numbers

v4.5.0 (2018-10-14)

  • Allow basic calculations when entering expressions like =12*78
  • Adds the formulaMode option, set to false by default, that controls if the formula mode is enabled
  • Adds the Lexer, Parser, Evaluator, ASTNode and Token classes for managing math expressions
  • Fixes Dist files contain eval
  • Merge the changes from 4.4.1 while making sure there is no regression with #609; this adds the browser field alongside the main one in package.json. Note: The browser option points to the minified library dist/autoNumeric.min.js
  • Update the index.html test file to use the un-minified development library dist/autoNumeric.js This allows to temporarily use forbidden functions like console or wrong formatting while debugging, using yarn build:dev
  • Fixes a call to _reformatAltHovered() even when the unformatOnHover option was set to false

v4.4.3 (2018-09-24)

  • Fixed: The unformatOnHover config value isn't used when set to false

v4.4.2 (2018-09-15)

  • Fixes Uncaught Error: Cannot find module 'autonumeric' on v4.4.1

v4.4.1 (2018-09-13)

  • Modify the package.json configuration main field to browser

v4.4.0 (2018-08-04)

  • Add a feature where emptyInputBehavior could be set to the minimum or maximum value, emptyInputBehavior now accepts either a number (or a string representing a number), or the 'min' or 'max' option
  • Fix the emptyInputBehavior validation test when checking the value limits
  • Allow emptyInputBehavior to be set to min, max, or a number

v4.3.7 (2018-07-28)

  • Fixes Pasting a negative value over a negative value that as a currency symbol and its numbers selected throws an error
  • Refactor the _onPaste() handler by removing duplicated parts
  • Fix the initialization call new AutoNumeric() where using as arguments a string (element selector), a number (initial value) and an array (array of options), in that particular order, would not be recognized

v4.3.1 (2018-07-24)

  • Modify the tenTrillions and oneBillion limits to be exact
  • Remove the maximumValue and minimumValue tenTrillionsNoDecimals option, and update tenTrillions so that it equals ten trillions
  • The tenTrillions sub-option is now equal to '10000000000000', and the oneBillion sub-option is now equal to '1000000000'
  • This change was long overdue since we modified in v4.0.0-beta.22 how the number of decimal places was defined by the user using the decimalPlaces options instead of adding a specific number of decimal to the min/max values.

v4.3.0 (2018-06-02)

  • Allow non-input tags with the readOnly option to set the contenteditable attribute to false
  • Fix the readonly and contenteditable attributes so that they can be updated to read/write mode
  • Modify _setReadOnly() so that it always sets the element to read-only mode
  • Create a new _setReadWrite() function that sets the element to read-write mode
  • Create a new _setWritePermissions() function that sets the element read only/write mode according to the readOnly setting
  • CURRENTLY WORKS AS A PURE JAVASCRIPT LIBRARY.
  • Fixed Event listeners are not set/reset on option updates.
  • Fixed Internet Explorer 11 throws when freezing the options
