Q1282 How do I sort an array of identical objects with more than one property within them, sorting the array on the values within any one of those properties?

<script language="JavaScript"><!--
function myObject(day,month,year,text,number) {
    this.day = day;
    this.month = month;
    this.year = year;
    this.text = text;
    this.number = number;
}

function setObject(day,month,year,text,number) {
    myObjectArray[objectArrayIndex++] = new myObject(day,month,year,text,number);
}

var objectArrayIndex = 0;
var myObjectArray = new Array();

setObject(4,11,97,"abc",5);
setObject(3,10,1996,"123",55);
setObject(2,9,1995,"122",123);
setObject(1,12,1998,"124",24);

function compareDay(a,b) { return a.day - b.day; }
function compareMonth(a,b) { return a.month - b.month; }
function compareYear(a,b) { return a.year - b.year; }
function compareText(a,b) { return a.text - b.text; }
function compareNumber(a,b) { return a.number - b.number; }

function showObjectArray(text,object,length) {
    document.write(text + ': ');
    for (var i=0; i<length; i++) {
        document.write('<br>' + object[i].day + ' ');
        document.write(object[i].month + ' ');
        document.write(object[i].year + ' ');
        document.write(object[i].text + ' ');
        document.write(object[i].number);
    }
    document.write('<br><br>');
}

//var myArray = new Array(333,5,44,2222,11111);
//var myArrayLength = 5;

showObjectArray('Unsorted',myObjectArray,objectArrayIndex);

myObjectArray.sort(compareDay);
showObjectArray('Sorted by Day',myObjectArray,objectArrayIndex);

myObjectArray.sort(compareMonth);
showObjectArray('Sorted by Month',myObjectArray,objectArrayIndex);

myObjectArray.sort(compareYear);
showObjectArray('Sorted by Year',myObjectArray,objectArrayIndex);

myObjectArray.sort(compareText);
showObjectArray('Sorted by Text',myObjectArray,objectArrayIndex);

myObjectArray.sort(compareNumber);
showObjectArray('Sorted by Number',myObjectArray,objectArrayIndex);
