一款支持多个图片文件批量上传插件代码下载,下载包里有服务端获取图片方法,是php语言。/* * 服务器地址,成功返回,失败返回参数格式依照jquery.ajax习惯; * 其他参数同WebUploader */ $('#test').diyUpload({ url:'server/fileupload.php', success:function( data ) { console.info( data ); }, error:function( err ) { console.info( err ); } }); $('#as').diyUpload({ url:'server/fileupload.php', success:function( data ) { console.info( data ); }, error:function( err ) { console.info( err ); }, buttonText : '选择文件', chunked:true, // 分片大小 chunkSize:512 * 1024, //最大上传的文件数量, 总文件大小,单个文件大小(单位字节); fileNumLimit:50, fileSizeLimit:500000 * 1024, fileSingleSizeLimit:50000 * 1024, accept: {} });服务端用法 php代码如下// Make sure file is not cached (as it happens for example on iOS devices) header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") .
