javascript正在尝试获取第三个嵌套的array.length和value

我有一个生成的嵌套数组来存储一些数据。

数组如下所示(这是一个动态生成的数组):

[
    ["Large", 
       ["yellow", "green", "Blue"],
       ["$55.00", "$55.00", "$55.00"]
     ]
    ["Medium",
       ["yellow", "green", "Blue", "Red"],
       ["$55.00", "$55.00", "$55.00", "$55.00"]
    ]
    ["small",
       ["yellow", "green", "Blue", "Red"],
       ["$55.00", "$55.00", "$55.00", "$55.00"]
    ]
]

我试图获得[“yellow”,“green”,“Blue”]数组的长度和循环来获得值

for(i=0; colorNSize.dataArray[0][0][1].length<i; i++){
    alert(colorNSize.dataArray[colorNSize.Sizeindex][0][0][i])// alert's A (which is the char[1] of the second array.
}

alert(colorNSize.dataArray[0][0][1].length) 实际上提醒“大”的长度是“5” 我还能在这里嵌套真正的第三个数组吗?
