I need to create global two dimensional array in jquery or javascript

My function is like this

On click of that button I am getting this error "globalArray[0] is undefined"

How can I create global dynamic multi dimensional array.

Answer

if (!globalArray[index]) 
    globalArray[index] = []; // init the array.

globalArray[index].push(name);

You have a typo with the dot:

$.("#uname").val();

Change to:

$("#uname").val();

What are you trying to do with this code?

Update: (The question was totally edited.)

Your code:

var globalArray[0] = new Array();

globalArray[0] is invalid variable name, you need first to declare the array:

var globalArray = []; // Array literal.
globalArray[0] =  [] // The element at position 0 is new an array.
