Answer 1

I've had to do this very thing. Here's the code I used:

$(function() {
    var 
    jqDdl = $('#ddl'),
    onChange = function(event) {
        if ($(this).val() === 'Other') {
            $('#otherTxtbox').show();
            $('#otherTxtbox').focus().select();
        } else {
            $('#otherTxtbox').hide();
        }
    };
    onChange.apply(jqDdl.get(0)); // To show/hide the Other textbox initially
    jqDdl.change(onChange);
});
