This plug-in supports multiple file selection functions, which is very good, and the code is simple
$("#fileUpload").fileUpload({
'uploader': 'style/uploader.swf',
'cancelImg': 'style/img/cancel.png',
'folder': '/mbs/fileUpload',
'script': '/mbs/FileUpload',
'buttonText': 'Durchsuchen',
'fileDesc': '*.jpg; *.gif;*.png',
'fileExt': '*.jpg;*.gif;*.png',
'scriptData': {'uploadAction': 'upload'},
'multi': true
});
'multi': true : This is the multi-file selection function.
'script': '/mbs/FileUpload': Background processing of uploaded files
'scriptData': {'uploadAction': 'upload'}: Variables that need to be included in post data
