  <script src="" type="text/javascript"></script>
  <script src="dist/jquery.maskMoney.min.js" type="text/javascript"></script>
  <input type="text" id="currency" />
  $(function() {


The options that you can set are:

  • prefix: the prefix to be displayed before(aha!) the value entered by the user(example: "US$ 1234.23"). default: ''
  • suffix: the suffix to be displayed after the value entered by the user(example: "1234.23 €"). default: ''
  • affixesStay: set if the prefix and suffix will stay in the field's value after the user exits the field. default: true
  • thousands: the thousands separator. default: ','
  • decimal: the decimal separator. default: '.'
  • precision: how many decimal places are allowed. default: 2
  • allowZero: use this setting to prevent users from inputing zero. default: false
  • allowNegative: use this setting to prevent users from inputing negative values. default: false
  • formatOnBlur: delay formatting of text field until focus leaves the field. default: false
  • reverse: by default, maskMoney applies keystrokes from right to left. use this setting to apply keystrokes from left to right.
  • selectAllOnFocus: select all text in the input when the element fires the focus event. default :false
  • allowEmpty: allow empty input values, so that when you delete the number it doesn't reset to 0.00. default: false

IMPORTANT: if you try to bind maskMoney to a read only field, nothing will happen, since we ignore completely read only fields. So, if you have a read only field, try to bind maskMoney to it, it will not work. Even if you change the field removing the readonly property, you will need to re-bind maskMoney to make it work.


We have 3 bonus methods that can be useful to you:

  • .maskMoney('destroy') removes maskMoney from an element.
  • .maskMoney('mask') apply the mask to your input. This method can work as a setter as well, if you pass a value to it, like this .maskMoney('mask', 1999.99)
  • .maskMoney('unmasked') return a float value (ex.: 'R$ 1.234,56' => 1234.56). PS: If you have only one input field, you should use this way .maskMoney('unmasked')[0], since it will always return an array.

You can also configure maskMoney options using the data-* API instead of passing it as a hash in the .maskMoney method call. To use it, simply set the options using data-<option>, like this:

	<input type="text" data-affixes-stay="true" data-prefix="R$ " data-thousands="." data-decimal="," />

And when you bind maskMoney to that field, we will read those options. ATTENTION: for settings that isn't entirely lowercase, you will need to use dashes instead of capital letters. For example, to set allowZero, you will need to add a attribute called data-allow-zero.
