我已經使用這個網站很多研究等,並發現它非常有用。JavaScript數組插入函數不起作用?
我一直在開發一些代碼,它會得到一個輸入id名稱列表,然後使用javascript/jquery將它們加在一起。
這就是我到目前爲止 - 它可能會很好,因爲我仍然是一個新手。
到目前爲止,代碼獲取的輸入名稱罰款。它也計算得很好,但是當我把數組放入「var fieldnames」時,計算停止工作?
當我複製數組(將其放入輸入後)並粘貼到「var fieldnames」時,它工作正常。
這個問題似乎是數組沒有正確地傳遞給「var fieldnames」?
這是來自頁面的代碼 - 它將數組放入底部的輸入中,僅用於調查目的,但計算不起作用,除非您手動輸入輸入名稱!
任何幫助將不勝感激。 感謝

您是否嘗試在body標籤之後添加您的腳本? – 2012-07-17 12:02:49
'fieldnames'是一個只包含一個元素的數組,它是'#sum'輸入的字符串值。這大概不是你想要的。 – Utkanos 2012-07-17 12:18:21
該代碼位於開始標籤下方?和fieldnames舉行測試這是字段的數組? – 2012-07-17 12:37:38
