我使用用户定义的 3 个值编写了一个相当简单的数组表。这 3 个值决定了变量的值。我以前写过类似的代码，但由于某种原因，我无法弄清楚为什么这个代码不起作用。桌子很大，所以我对尺寸感到抱歉。 。 。

var ssRidgeQty=document.getElementById("ssRidgeTrim").value;

var ssRidgeWidth=document.getElementById("ssRidgeWidth").value;

var ssRidgeColorUp;
if (ssColorChoice=="galvalume")
{
    ssRidgeColorUp="1";
}
else if (ssColorChoice=="Dark Gray" || ssColorChoice=="Antique Bronze" ||     ssColorChoice=="Rural Red" || ssColorChoice=="Dark Green" || ssColorChoice=="Fern Green")
{
    ssRidgeColorUp="2";
}
else if (ssColorChoice=="metallic copper")
{
    ssRidgeColorUp="3";
}
else if (ssColorChoice=="none" && ssRidgeQty>0)
{
    ssRidgeColorUp=0;
    alert ("please choose a ss color");
}
else
{
    ssRidgeColorUp="4";
}

var ssRidgeCap = new Array();

ssRidgeCap [[2],[4],[40]] = 62.5;    

var ssRidgePrice = ssRidgeCap [[priceLevel],[ssRidgeColorUp],[ssRidgeWidth]];


document.getElementById("ssRidgeTest4").innerHTML=ssRidgePrice;

结果始终来自标记为 Wholesale syl-pol 的最后一组数组。如果我改变宽度，那么值就会改变，但是如果我改变价格水平或颜色（数组中的前 2 个 []，则没有任何变化。由于某种原因，这些值被卡在 [2] 和 [4] 上。

如果您需要任何其他参考，请询问，我会发布。我需要紧急帮助

（ps。价格水平由标记为 1、2、3 的单选按钮设置，当我进行测试以打印出三个决定变量“priceLevel”、“ssRidgeColorUp”和 ssRidgeWidth 时，它们总是正确出现，但数组是不接他们？

提前感谢您的宝贵时间。

使用对象代替数组

var ssRidgeCap = {
    pl_0 : {
        rc_1 : {
            rw_14 : 21.75,
            rw_16 : 28.1
        },
        rc_2 : {
            rw_14 : 25.85,
            rw_16 : 31.3
        }
    },
    pl_1 : {
        rc_1 : {
            rw_14 : 20.38,
            rw_16 : 26.5
        },
        rc_2 : {
            rw_14 : 25.2,
            rw_16 : 30.5
        }
    }
}

然后

var ssRidgePrice = ssRidgeCap['pl_' + priceLevel]['rc_' + ssRidgeColorUp]['rw_' + ssRidgeWidth];

另一种解决方案是使用多维数组

var ssRidgeCap = new Array();

ssRidgeCap[0] = [];
ssRidgeCap[0][1] = [];
ssRidgeCap[0][1][14]= 21.75;

然后可以使用

ssRidgeCap[0][1][14]

为什么不在一个命令中定义一个多维数组？

访问一个 multidim 数组元素（比如 2 dim）的语法是

a[i][j] = X;

此外，当您访问已定义数组的不存在元素时，如果不存在，则会创建所有前面的元素。

当您访问非现有数组的（非）现有元素时，将发生错误。

var a = [];
a[5] = 4; // ok, elements 0,1,2,3,4 are created and set to undefined
a[6][4] = 53; // not ok, error, cannot convert undefined to object.

示例定义

var ssRidgeCap = 
[
   // 0
  [
     // 0, 0
     [ 54, 35, 64 ],
     // 0, 1
     [ 54, 23, 66 ]
   ],
   // 1
      // 1, 0
      [ 23, 6, 75],
      // 1, 1
      [ 22,  66, 22]
   ]
];
