Trigger jQueryUI datePicker on button click, send result to disabled input field

Question

I\'ve been searching for a way to do this, but could not find anything

I want to have a:

• Disabled input text field, called #XX. This input will

Answer 1

Might be to late but I just did this

$("#firstDate").datepicker({
    onSelect: function () {
        myfunc();
    }
}); 

$("#secondDate").datepicker({
    showOn: ''
}); 

function myfunc(){
    var fDate = $('#firstDate');
    var sDate = $('#secondDate');
    sDate.val(fDate.val());
}

It doesn't show the datepicker clicking the input and doesn't display the button to show the datepicker. Disabled doesn't work in my case because I need to extract the value from that input field.
