Politespace

Demo

Using Politespace

Add data-politespace to your form’s input[type=text] (et al) or textarea and we’ll add spaces to the value when the user blurs off of it. We’ll also remove those spaces on focus.

data-politespace-grouplength

To customize the number of spaces, use the data-politespace-grouplength attribute (it defaults to 3). It can be:

• single number (to uniformly repeat, like a credit card)
• a comma delimited list (for non-uniform strings, like "2,4" for MM YYYY). This also works with open ended commas, like "2," for MM YYYY or "3,3," for a US phone number.

Use pattern="[0-9]*" for numeric keyboards on iOS.

This script now works reliably cross-browser with <input type="number">. It should be noted that independent of politespace, WebKit removes the value on blur when a user types or a script adds a non-numeric character in the field, for example: myElement.value = "1,000". We’re now creating a proxy element on top of the form element to workaround this issue and display the formatted value.

Make sure your maxlength value is large enough to allow for the addition of the whitespace.

data-politespace-delimiter

The default delimiter is a space, but you can add data-politespace-delimiter to customize to a different character.

data-politespace-reverse

When delimiting money, for example, you want the grouplengths to be calculated from the lowest digit to the greatest (from right to left). Use data-politespace-reverse to opt into this behavior. A USD Price example: data-politespace-grouplength="3" data-politespace-delimiter="," data-politespace-reverse

data-politespace-decimal-mark

When delimiting money as a floating point, you’ll want to exclude the fractional portion of the number when inserting delimiters. For example, $4,000.34 will need data-politespace-delimiter="," data-politespace-decimal-mark="." (or for proper internationalization, $4 000,34 will need data-politespace-delimiter=" " data-politespace-decimal-mark=",").

data-politespace-strip

Specify a regular expression of characters to remove before formatting the field. To strip out all non-numeric characters (for example, for a telephone number), use data-politespace-strip="[^\d]*". This is an alternative to the numeric-input plugin of formcore.

data-politespace-creditcard

When using politespace with credit card fields, the formatting logic changes based on the first digit. For example, American Express (AMEX) card formats are 4,6,5 (15 characters total, the first digit is a 3) and Visa/Mastercard/Discover are 4,4,4,4 (16 characters). If you use the data-politespace-creditcard attribute (in lieu of a data-politespace-grouplength) politespace will automatically adjust the politespace group length for you. If you add the data-politespace-creditcard-maxlength attribute, politespace will also manage the field’s maxlength for you as well.

<input type="text" pattern="[0-9]*" data-politespace data-politespace-creditcard data-politespace-creditcard-maxlength>

Uses the creditable dependency.

data-politespace-us-telephone

When using politespace with US specific telephone number fields, data-politespace-us-telephone option will automatically adjust the maxlength of the field to account for a US country code. If the user types a 1, the maxlength will be adjusted to add one additional character until the user blurs, when the country code will be stripped and the original maxlength restored.

Beware input masks.

This plugin was created as a less intrusive alternative to the common input mask, which have serious accessibility implications:

Just a friendly monthly reminder that input mask plugins make your forms sound like a jackhammer to people who use a screen reader. Cheers!
