How can I reset a form with jQuery chosen plugin?

You’ll need to reset the value of the field, then trigger the liszt:updated event on the input to get it to update, ive made a fiddle with a working example here.

$(".chzn-select").chosen();
$('a').click(function(){
    $(".chzn-select").val('').trigger("liszt:updated");
});​

Since the release of chosen v1.0 the trigger is now called ‘chosen:updated’. Anyone using this new version needs to trigger the update using

$(".chosen-select").val('').trigger("chosen:updated");
