JS Function To Get Clone Of Object

Way to Clone A Object In JavaScript

var ObjectHandler = {
//public method
getCloneOfObject: function(oldObject) {
var tempClone = {};
if (typeof(oldObject) == "object")
{
for (prop in oldObject)
{
// for array use private method getCloneOfArray
if ((typeof(oldObject[prop]) == "object") &&(oldObject[prop]).__isArray)
tempClone[prop] = this.getCloneOfArray(oldObject[prop]);
// for object make recursive call to getCloneOfObject
else if (typeof(oldObject[prop]) == "object")
tempClone[prop] = this.getCloneOfObject(oldObject[prop]);
// normal (non-object type) members
else
tempClone[prop] = oldObject[prop];
}
return tempClone;
}
},
//private method (to copy array of objects) - getCloneOfObject will use this internally
getCloneOfArray: function(oldArray) {
var tempClone = [];
for (var arrIndex = 0; arrIndex <= oldArray.length; arrIndex++){
if (typeof(oldArray[arrIndex]) == "object")
tempClone.push(this.getCloneOfObject(oldArray[arrIndex]));
else tempClone.push(oldArray[arrIndex]); return tempClone;
}
}
};

How To Use

var eventDetail = { description:"",summary:"",startTime:new Date(),endTime:new Date(),location:""};

Check What will Happen If you use normal way:

var copyOfeventDetail=eventDetail;
copyOfeventDetail.description="New Description";
alert("Copy description"+copyOfeventDetail.description+"Original Description" +eventDetail.description);

Check What will Happen If you use cloning way:
var cloneOfeventDetail =ObjectHandler.getCloneOfObject(eventDetail);
cloneOfeventDetail .description="New Description";
alert("Clone description"+cloneOfeventDetail .description+"Original Description" +eventDetail.description);
