Field Masks from JQuery or JavaScript to Bonita

I need to customize masks (date, zip code, etc) from JavaScript or JQuery to Bonita. How can I do this? I saw the JQuery site and I didn´t get. Someone could help me? My name is Jefferson, and I a Database student. Thank you everybody.

you need to attach an onchange event to the field in JavaScript and do it this way.

Note: calling yourself Jefferson and posting under the name of Rafael is interesting…why not just create your own ID?
