我需要在jquery或javascript中创建全局二维数组

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

我的功能就是这样

<script>

var globalArray[0] = new Array();

function createArray(){

    alert(globalArray[0]);         
}

</script>

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

单击该按钮时，我得到此错误"globalArray[0] is undefined"

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

推荐答案

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

globalArray[index].push(name);

您有一个带点的错字:

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

更改为:

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

您打算如何处理此代码?

更新 :(问题已完全编辑.)

Update: (The question was totally edited.)

您的代码:

var globalArray[0] = new Array(); 

globalArray[0]是无效的变量名，您需要首先声明该数组:

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.
