Masked Input Plugin for jQuery
- a - Represents an alpha character (A-Z,a-z)
- 9 - Represents a numeric character (0-9)
- * - Represents an alphanumeric character (A-Z,a-z,0-9)
If your requirements aren't met by the predefined placeholders, you can always add your own. For example, maybe you need a mask to only allow hexadecimal characters. You can add your own definition for a placeholder, say 'h', like so:
$.mask.definitions['h'] = "[A-Fa-f0-9]"; Then you can use that to mask for something like css colors in hex with a mask "#hhhhhh".
By design, this plugin will reject input which doesn't complete the mask. You can bypass this by using a '?' character at the position where you would like to consider input optional. For example, a mask of "(999) 999-9999? x99999" would require only the first 10 digits of a phone number with extension being optional.
