问题描述

Hi
我正在尝试在JavaScript中创建2D数组以存储一些数据库值，这是我的代码

Hi I am trying to create 2D array in JavaScript to store some Database values, here is my code

function fillArrays(ImageSmall, ImageBig, Title, DealId, Description) {

       var array_Data = new Array(ImageSmall, ImageBig, Title, DealId, Description);

       array_Obj[array_Obj.length - 1] = array_Data; //var array_Obj= new Array() its written //above
       var obj = array_Obj[0];

   }

正在创建阵列很好，我在从内部数组中提取数据时遇到问题，即array_Data，其值为ImageSmall，ImageBig ，标题，DealId，描述在它。



i之前是这样尝试

Arrays are being created Fine, i am having problem extracting data from the inner Array i.e "array_Data" which have values of "ImageSmall, ImageBig, Title, DealId, Description" in it.

i was trying like this before

alert (array_Obj[0][0]);  // not working for me
var obj= array_Obj[0];
alert (obj[0]); // not working too for me. 

我会感谢任何帮助。

I'll Appreciate any help.
