大家好我正在使用JavaScript來填充值。我使用這個腳本JavaScript從另一個變量填充值
String Vegs[]= request.getParameterValues("Vegs");
String qty_carrot=request.getParameter("quantity_carrot");
String qty_tomato=request.getParameter("quantity_tomato");
String qty_cabbage=request.getParameter("quantity_cabbage");
String qty[];
qty[0]=qty_carrot;
qty[1]=qty_tomato;
qty[2]=qty_cabbage;
,但它說,錯誤的局部變量數量是尚未初始化..
還當我的代碼更改爲這個
String qty[]=new array(3);
qty[0]=qty_carrot;
qty[1]=qty_tomato;
qty[2]=qty_cabbage;
它說陣列不能爲分辨率爲

@ user1799574,你的職位是在JSP中,而不是JavaScript數組scriplet!試一試我發佈的答案。 – Arvind 2014-09-02 05:25:32
是的,我曾嘗試說,類型不匹配不能從字符串轉換爲字符串[] – 2014-09-02 05:28:05
@ user1799574,你可以發佈堆棧跟蹤,這將是有益的 – Arvind 2014-09-02 05:29:29
