jquery動態依賴從多維數組中選擇

我想要有一個窗體與兩個下拉選擇從數組填充選擇選項。第一個選擇只有一個數組，但是取決於選擇，我想用特定的多維數組填充第二個數組。我可以單獨執行它們，但我無法將數組名從第一個選擇傳遞給函數以填充第二個選項。jquery動態依賴從多維數組中選擇

我很新的JavaScript和jQuery 1.11.0，並希望有任何幫助。

這是我正在使用的代碼。

你是否堅持使用這種形式的信息，或者你自己在編寫這些數組？如果您可以修改它們，則關聯數組可能是更好的選擇。 – ntrrobng 2015-04-01 04:33:09

不，我自己寫這些數組。正如我所說我對jQuery（我的第一個項目）非常陌生，我無法讓聯合數組工作。 – geno 2015-04-01 17:06:46

您可以使用「EVAL」得到結果的可變數據。

我的建議是，從陣列像創建一個對象：

var aircrafts = { "N901AH" : N901AH, "N902AH" : N902AH, "N903AH" : N903AH, "N904AH" : N904AH, "N905AH" : N905AH, "N907AH" : N907AH};

此外，而不是爲循環使用$。每個（陣列處理（指數，元件））。然後，而不是eval（）函數使用該選項的文本，讓你從對象需要數組：

console.log(aircrafts["N901AH"]);//example

和填充第二選擇。這是我的小提琴： jsfiddle for my answer

問候。

有沒有一個原因不是eval（）？ – geno 2015-04-01 10:07:00

它將字符串轉換爲可執行的JavaScript。這是攻擊的一個可能的突破點。更多鏈接： http://jslinterrors.com/eval-is-vil – mzografski 2015-04-01 11:16:48

jquery動態依賴從多維數組中選擇
