if (!globalArray[index])
globalArray[index] = []; // init the array.
globalArray[index].push(name);
You have a typo with the dot:
你的点有错别字：
$.("#uname").val();
Change to:
改成：
$("#uname").val();
What are you trying to do with this code?
你想用这段代码做什么？

更新：（问题已完全编辑。）
Your code:
您的代码：
var globalArray[0] = new Array();
globalArray[0]is invalid variable name, you need first to declare the array:
globalArray[0]是无效的变量名，你需要先声明数组：
var globalArray = []; // Array literal.
globalArray[0] = [] // The element at position 0 is new an array.

Intead of
代替
if(loop == 0){
globalArray[index][0] = uname;
}else{
globalArray[index][loop++] = uname;
}
Use this
用这个
if(loop > 0){
globalArray[index][loop++] = uname;
}else{
globalArray[index][0] = uname;
}
