        $('#day').val(dateText.split('/')[1]);
    }


    });


});
</script>

Answer 1

Try writing a named function and call it on both events:

function doSomething() {
    // ...
}
$(document).ready(function() { doSomething() });
$(yourElem).on("click", function() { doSomething() });

Alternatively to writing an anonymous function as a callback, just to call doSomething , you could also pass the function name as an argument, gaining a little performance by not cluttering memory with unnecessary anonymous functions:

$(document).ready(doSomething);
$(yourElem).on("click", doSomething);

$(document).ready(function(){
  $("#fullDate").datepicker({
    showOn: "button",
    buttonImage: "images/calender.jpg",
    buttonImageOnly: true,

    onClose: function(dateText, inst) {
        $('#year').val(dateText.split('/')[2]);
        $('#month').val(dateText.split('/')[0]);
        $('#day').val(dateText.split('/')[1]);
    }
  });
  $("#fullDate").datepicker("show"); // this will run once.
});

During load, you can use

//when window loads
$(window).load(function(){
    functionCallHere();
});

//or when DOM is ready
$(document).ready(function(){
    functionCallHere();
});

Then for the click

$(element).click(function(){
    functionCallHere();  //call the function again
});

Where functionCallHere is the name of the common function called on those events.
