The newest item will be the one with the highest index.

var lastItem = arrayObj[ arrayObj.length - 1];

Array Object has the length property, not size.

i have created an array like this ,is it correct?

It's close, but javascript is CaseSensitive. (array should be Array)

Here's a short demo:
function demoFunc()
{
var i, mArray = new Array();
for (i=0; i<10; i++)
mArray[ i ] = "Int: " + i;

for (i=0; i<10; i++)
mArray[ mArray.length ] = "Float: " + (0.5+i);

var ul = document.createElement('ul');
var len = mArray.length;
for (i=0; i<len; i++)
{
var li = document.createElement('li');
li.appendChild( document.createTextNode( mArray[i] ) );
ul.appendChild(li);
}
document.body.appendChild(ul);
}

Visis w3fools.com followed by w3schools.com

JavaScript/Reference/Global_Objects/Array

w3schools.com

( do read w3fools.com, it's enlightening)

thankyou bro,but y u against w3schools..i thik w3schools preety gud

No worries mate.

Why I'm against w3schools?
I've noticed incomplete, trivial examples in far too many cases. I could go on and on and on, but the article I linked to will do a far better job than I can.

I've fixed the links in my above comment, and will repeat one.

I really suggest you read it. (I'd throw rocks at w3schools.com if they were in range)

Solution 1

Try this:

var registeredElements = [];

// enter data in array

var LastArrayIndexValue = regManadatoryElements[regManadatoryElements.length];
