我嘗試上傳多個圖像到服務器。 我可以點擊圖片並以塊形式顯示，但無法將其傳輸到服務器。錯誤我得到的是04-02 10:35:41.984: I/chromium(23772): [INFO:CONSOLE(104)] "Uncaught TypeError: Cannot call method 'lastIndexOf' of undefined", source: file:///android_asset/www/index.html (104)多個圖像上傳到服務器在科爾多瓦

我想有一些問題function uploadPhoto()。 Foreach循環沒有正確處理imageURI。 什麼是解決方案？
我怎樣才能檢索到服務器端？我嘗試了下面的代碼：'new_image_name = array（「red.jpg」，「green.jpg」，「blue.jpg」）; foreach（$ new_image_name爲$ value）{ $ destination = $ _SERVER ['DOCUMENT_ROOT']。 「/AppData/uploads/".$value; move_uploaded_file（$ _ FILES [「file」] [「tmp_name」]，$ destination）; }'但只有1張圖片上傳（red.jpg）。 – 2015-04-02 06:24:10
請檢查上傳函數chunkedMode和fileKey選項，對於服務器端，我使用的是asp.net mvc。 – Ashokbharathi 2015-04-02 06:39:33
