jQuery的创建多维数组 [英] jQuery Create Multidimensional Array

问题描述

我有一个时间试图找出如何在jQuery的一个多维数组赫克。

I am having a heck of a time trying to figure out how to create a multidimensional array in jQuery.

我实例环路以外的阵列。

I instantiate the array outside of the loop.

 <script>
 var myArray = [];
 </script>

我的内循环我想添加的数组元素。

Inside of my loop I want to add the array elements.

 i = 0
 [loop start]
      <script>
      myArray[i][$row[sku]] = $row[qty]; // sku might be repeated will this cause an issue? You will see in the error below "295518" is repeated...
      <script>
 [loop end]

在我的源$ C ​​$ C，它看起来是这样的：

In my source code it looks like this:

 <script>
 myArray[ 1 ][ 295518 ] = 122;
 </script>

然后我运行这个在循环外底...

Then I run this at the end outside the loop...

 <script>
 console.log( myArray );
 </script>

我得到在控制台这个错误：

I get this error in the console:

Uncaught TypeError: Cannot set property '295518' of undefined 
Uncaught TypeError: Cannot set property '70252' of undefined 
Uncaught TypeError: Cannot set property '295518' of undefined 

我在做什么错在建立这个数组？谢谢！

What I am doing wrong in setting up this array? Thanks!

推荐答案

你可以这样做：

var a = [];
a[0] = [1,2,3]; 
a[1] = [4,5,6]; 

a[1][1] it is 5
