我該如何解決這個數組表？

-1

我寫了一個相當簡單的數組表，使用由用戶定義的3個值。這3個值確定變量的值。我之前寫過類似的代碼，但由於某種原因，我無法弄清楚爲什麼這個不起作用。該表很大所以我很抱歉的大小...我該如何解決這個數組表？

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"); 
}

    ssRidgeColorUp="4";

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


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

結果總是來自最後一組數組標籤批發syl-pol。如果我改變寬度，那麼值會改變，但如果我改變價格水平或顏色（數組中的第一個2 []]，則沒有任何更改。由於某些原因，這些值會粘在[2]和[4]上。我需要緊急幫助

（ps。價格水平由一個單選按鈕1,2,3組成，當我做一個測試打印出來這三個變量決定「priceLevel」，「ssRidgeColorUp」，並ssRidgeWidth，他們總是正確，但數組不接他們？

預先感謝您的寶貴時間。

是否有任何理由您不會使用描述該對象的對象數組事情呢？另外，你可以發佈一個jsfiddle嗎？我會有興趣看到它的一個例子。 – Justin 2013-05-08 13:08:54

什麼是jsFiddle？使用大型陣列更容易。我只是不知道爲什麼這不起作用。即使我告訴代碼寫ssRidgeCap也開始打印19.1的價值 – 2013-05-08 13:13:05

JSFiddle.net是一個整潔的小網站，您可以在其中檢查代碼或與其他人共享。在找出使用代碼的上下文並且它可能是您發佈導致該問題的東西之外的其他內容時，將會有很長的路要走。 – Justin 2013-05-08 13:22:25

另一種解決方案是使用一個多維數組

var ssRidgeCap = new Array(); 

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

然後，它可以訪問使用

ssRidgeCap[0][1][14]

2013-05-08 13:37:15

我認爲這可能工作，但是我必須創建另一個數組在ssRidgeCap [0] [2] – 2013-05-08 13:43:09

@ABBryan是的，這是整個多維array – 2013-05-08 13:46:09

謝謝你的幫助，我現在就開始工作。 – 2013-05-08 13:47:05

相反的陣列的使用對象

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 
     } 
    } 
}

然後

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

爲了更新這些價格，一個對象會花費更多的時間。這個數組應該工作，我寧願找出它有什麼問題。 – 2013-05-08 13:18:46

@ABBryan AFAK由您建模的陣列將無法工作，如果您需要將其製作成三維陣列 – 2013-05-08 13:23:27

那麼我該怎麼做？ – 2013-05-08 13:25:02

何不在一個命令定義多維數組？

用於訪問一個multidim數組元素的語法（比如2暗淡）是

a[i][j] = X;

此外，當訪問一個定義陣列的不存在的元素，所有前面元素的創建，如果不存在。

當您訪問非現有數組的（非）現有元素時，將發生錯誤。

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.

一個例子定義

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

所以這... ssRidgeCap [[0]，[1]，[14]] = 21.75;應該是這個... ssRidgeCap [0,1,14] = 21.75？ – 2013-05-08 13:34:20

也許你需要多一點小心。它應該是ssRidgeCap [0] [1] [14] = 21.75 – basos 2013-05-10 14:50:58

我該如何解決這個數組表？
