关于使用jQuery插件时后台session丢失的问题

之前:

$(document).ready(function()

{

$("#uploadifydoc").uploadify({

'uploader': '${pageContext.request.contextPath}/uploadify/scripts/uploadify.swf',

'cancelImg': '${pageContext.request.contextPath}/uploadify/cancel.png',

'script': '${pageContext.request.contextPath}/yxjxalzbworks!uploadDoc?id=${USER.id}',

'scriptData':'{docname:"xxxxx", vid:1}',

'queueID':'fileQueue',

'auto': false,

'multi': true,

'queueSizeLimit':10,

'sizeLimit' : 102400000,

'fileExt' : '*.doc;*.docx;*.xls;*.xlsx;*.ppt;*.pptx;*.pdf',

'fileDesc' : '只能上传(.doc, .docx, .xls, .xlsx, .ppt, .pptx, .pdf)格式的图片',

'display' : 'speed',

'buttonText' : 'Add Document',

'onComplete' : function(event, ID, fileObj, response, data) {

unknown+=fileObj.name+"#@#";

},

'onAllComplete' : function(event,data) {

$("#fn").val(unknown);

flag = 1;

}

});

});

修改之后：

$(document).ready(function()

{

$("#uploadifydoc").uploadify({

'uploader': '${pageContext.request.contextPath}/uploadify/scripts/uploadify.swf',

'cancelImg': '${pageContext.request.contextPath}/uploadify/cancel.png',

'script': '${pageContext.request.contextPath}/yxjxalzbworks!uploadDoc;jsessionid=${pageContext.session.id}?id=${USER.id}',

'scriptData':'{docname:"xxxxx", vid:1}',

'queueID':'fileQueue',

'auto': false,

'multi': true,

'queueSizeLimit':10,

'sizeLimit' : 102400000,

'fileExt' : '*.doc;*.docx;*.xls;*.xlsx;*.ppt;*.pptx;*.pdf',

'fileDesc' : '只能上传(.doc, .docx, .xls, .xlsx, .ppt, .pptx, .pdf)格式的图片',

'display' : 'speed',

'buttonText' : 'Add Document',

'onComplete' : function(event, ID, fileObj, response, data) {

unknown+=fileObj.name+"#@#";

},

'onAllComplete' : function(event,data) {

$("#fn").val(unknown);

flag = 1;

}

});

});

只需要在请求路劲上添加“；jsessionid=${pageContext.session.id}”就可以了（即把sessionid传到后边，然后去到的session就是现在的以前的session了）。
