Usage:

jQuery(document).ready(function ($) {
  $('#field_id').sprightlyFields({
    "_value1_": '#value1Selector',
    "_value2_": '#value2Selector',
    "default": '#defaultSelector'}, {clearFields : true});
});

In the example below, the element that has id "satFields" will be shown when the field with id "test_score_name" has a value of "SAT". All other fields declared("#actFields" and "#otherFields") will be hidden. If the field value doesn't match "SAT" or "ACT" then the element "#otherFields" will be shown.

jQuery(document).ready(function ($) {
  $('#test_score_name').sprightlyFields({
    "SAT": '#satFields',
    "ACT": '#actFields',
    "default": '#otherFields'}, {clearFields : true});
});
