jquery.maskedinput programmatically set value and apply mask?

Question

I'm using DigitalBush's MaskedInput jquery plugin. I have a simple input box for a phone number:

$('#txt_PhoneNumber').mask('[phone]');

Sometimes the field is programmatically filled with a non-formated number such as 5551234567. How can I notify the mask input to apply it's mask to "beautify" it's new input?

Answer 1

Perhaps things have changed since this question was asked, because Jason P's first suggestion appears to work now.

$('#txt_PhoneNumber').trigger('input');

jsfiddle

The following should work too:

$('#txt_PhoneNumber').trigger('paste');
