This question already has an answer here:

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

My function is like this

<script>

var globalArray[0] = new Array();

function createArray(){

    alert(globalArray[0]);         
}

</script>

<div><input type='button' value='save' onclick='createArray();'> </div>

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

How can I create global dynamic multi dimensional array.

Is that dot $.("#uname") a typo? – VisioN Jun 4 '12 at 10:42
What are you trying to do with this code? – gdoron Jun 4 '12 at 10:46

@gdoron Seems like simple element pushing but in a bit strange way. – VisioN Jun 4 '12 at 10:48
index never changes, so why is it even there? also uname is undefined. Lack of details is causing more questions than answers – charlietfl Jun 4 '12 at 10:48

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.

Just globalArray[index].push(uname). – VisioN Jun 4 '12 at 10:49

Intead of 

if(loop == 0){
 globalArray[index][0] = uname;
}else{
  globalArray[index][loop++] = uname;
}

Use this

if(loop > 0){
    globalArray[index][loop++] = uname;     
}else{
    globalArray[index][0] = uname;      
}
