Phone mask with jQuery and Masked Input Plugin

Question

I have a problem masking a phone input with jQuery and Masked Input Plugin.

There are 2 possible formats:

1. (XX)XXXX-XXXX
2. (

Answer 1

The best way to do this is using the change event like this:

$("#phone")
.mask("(99) 9999?9-9999")
.on("change", function() {

    var last = $(this).val().substr( $(this).val().indexOf("-") + 1 );

    if( last.length == 3 ) {
        var move = $(this).val().substr( $(this).val().indexOf("-") - 1, 1 );
        var lastfour = move + last;
        var first = $(this).val().substr( 0, 9 ); // Change 9 to 8 if you prefer mask without space: (99)9999?9-9999

        $(this).val( first + '-' + lastfour );
    }
})
.change(); // Trigger the event change to adjust the mask when the value comes setted. Useful on edit forms.
