jQuery Price Format Plugin is a plugin to format input text fields as prices. For example, if you type 123456, the plugin updates it to US$ 1,234.56. It is costumizable, so you can use other prefixes and separators (for example, use it to get R$ 1.234,55), use plus sign and minus sign.
Now in the version 2.0, jQuery Price Format can be used for any HTML element.
