http://stackoverflow.com/questions/16723877/jquery-file-upload-maxnumberoffiles-and-getnumberoffiles-options I believe getNumberOfFiles was only added as an option to a recent version of jquery.fileupload-ui.js (8.2.1). As an alternative, you can set the option singleFileUploads to false, and in the add callback you can throw errors if more than one file is added. var maxFiles = 1; $('#fileupload').fileupload({ singleFileUploads: false, url: '/uploadUrl' }).bind('fileuploadadd', function (e, data) { var fileCount = data.files.length; if (fileCount > maxFiles) { alert("The max number of files is "+maxFiles); return false; } });

https://github.com/blueimp/jQuery-File-Upload/issues/622 看連結最下面 Here is some updated code that works with the most recent version as of July 18, 2014. class CustomUploadHandler extends UploadHandler { /* Converts a filename into a randomized file name */ private function _generateRandomFileName($name) { $ext = pathinfo($name, PATHINFO_EXTENSION); return md5(uniqid(rand(), true)).'.'.$ext; } /* Overrides original functionality */ protected function trim_file_name($file_path, $name, $size, $type, $error, $index, $content_range) { $name = parent::trim_file_name($file_path, $name, $size, $type, $error, $index, $content_range); return $this->_generateRandomFileName($name); } } $upload_handler = new CustomUploadHandler();

像最近弄php後台，jquery php css jtable database jqueryfileupload,整個用了一遍 結論 要有好用 快速的framework 真的用ror肯定沒錯，因為開發久了，pg才是真正花時間的，省不下，沒工具就是省不下時間 回頭看java真的是怪物，開發速度暴減 php用framework就像ror一樣，主機是不開放更新framework

基本上官方的fnGetData和fnGetPosition之類，fnGetPosition拿到是抓出幾筆中第幾筆id和真正的Row_ID不一樣。用fnGetData一直拿到Object，根本解不開，試了官方和網路上的方式，全都不行。 fnrender被拿掉了…..無法判斷Object 最快方式：直接用jquery $(’#datatable tbody’).on( ‘click’, ’tr’, function () { 這行會取得tr 底下直接用 row_id = $(this).attr(‘id’).split("_")[1]; $(this).attr(‘id’)會找到tr用的id，得到值：ROW_22 split("_")之後：ROW 22，取[1]，就行得到id。
