Surely many of you already know this great plugin (Masked Input Plugin from Josh Bush) to facilitate data entry forms by assigning a mask to facilitate the introduction of structured data.

The plugin works really well, but we think it was a major weak point for some types of data, in particular to enter dates. The eternal question of what value (month or day) should be first, depending on the language and the place where you are. To fix this we have slightly modified the plugin to accept a "placeholder" of more than one character and that will be displayed when editing the input until it is completed.

With this modification, the plugin accepts values of more than one character in the configuration parameter "placeholder"

    $ ("#date").mask ("99/99/9999", {placeholder: 'dd/mm/yyyy'});

Here you can see an full example of use.
