ajaxfileupload文件上传带参数,json序列化到后台!

前几天使用了ajaxfileupload方法传文件带上json数据,到controller这么都是接受到"{"这个符号.

仅需对ajaxfileupload文件进行源码的更改即可,附上代码,可直接创建.js文件后直接粘贴即可使用.

jQuery.extend({    createUploadIframe: function(id, uri) {   //create frame            var frameId = 'jUploadFrame' + id;                       if(window.ActiveXObject) {                var io = document.createElement('<iframe id="' + frameId + '" name="' + frameId + '" />');                if(typeof uri== 'boolean'){                    io.src = 'javascript:false';                }                else if(typeof uri== 'string'){                    io.src = uri;                }            }            else {                var io = document.createElement('iframe');                io.id = frameId;                io.name = frameId;            }            io.style.position = 'absolute';            io.style.top = '-1000px';            io.style.left = '-1000px';            document.body.appendChild(io);            return io    },    createUploadForm: function(id, fileElementId, data) {  //create form  var formId = 'jUploadForm' + id;  var fileId = 'jUploadFile' + id;  var form = $('<form  action="" method="POST" name="' + formId + '" id="' + formId + '" enctype="multipart/form-data"></form>');  var oldElement = $('#' + fileElementId);  var newElement = $(oldElement).clone();  $(oldElement).attr('id', fileId);  $(oldElement).before(newElement);  $(oldElement).appendTo(form);   //<span style="color:#ff0000;">增加文本参数的支持,修改本处,本处应有掌声 </span>         if (data) {              for (var i in data) {                 var temp =  $('<input type="hidden" name="' + i +'" />');               temp.val(data[i]);               temp.appendTo(form);              }          }     //set attributes  $(form).css('position', 'absolute');  $(form).css('top', '-1200px');  $(form).css('left', '-1200px');  $(form).appendTo('body');  return form;    },    ajaxFileUpload: function(s) {        // TODO introduce global settings, allowing the client to modify them for all requests, not only timeout        s = jQuery.extend({}, jQuery.ajaxSettings, s);        var id = new Date().getTime()          var form = jQuery.createUploadForm(id, s.fileElementId, s.data);  var io = jQuery.createUploadIframe(id, s.secureuri);  var frameId = 'jUploadFrame' + id;  var formId = 'jUploadForm' + id;        // Watch for a new set of requests        if ( s.global && ! jQuery.active++ )  {   jQuery.event.trigger( "ajaxStart" );  }                    var requestDone = false;        // Create the request object        var xml = {}          if ( s.global )            jQuery.event.trigger("ajaxSend", [xml, s]);        // Wait for a response to come back        var uploadCallback = function(isTimeout)  {   var io = document.getElementById(frameId);            try   {    if(io.contentWindow)    {      xml.responseText = io.contentWindow.document.body?io.contentWindow.document.body.innerHTML:null;                  xml.responseXML = io.contentWindow.document.XMLDocument?io.contentWindow.document.XMLDocument:io.contentWindow.document;         }else if(io.contentDocument)    {      xml.responseText = io.contentDocument.document.body?io.contentDocument.document.body.innerHTML:null;                 xml.responseXML = io.contentDocument.document.XMLDocument?io.contentDocument.document.XMLDocument:io.contentDocument.document;    }            }catch(e)   {    jQuery.handleError(s, xml, null, e);   }            if ( xml || isTimeout == "timeout")   {                requestDone = true;                var status;                try {                    status = isTimeout != "timeout" ?

付上传输的格式

$.ajaxFileUpload({url:'url路径',data:{"arry":getSearchFormDataJson($("#Form"))},fileElementId:"uploadFiles",//只需要传递file的ID号过去就可以了            cache : false,            async : true,            type : "POST",            dataType : 'json',async: false,    error: function(request) {    alert("操作失败!");    },    success: function(data) {    if('success'==data){    alert("操作成功!");        }    }});

附上序列化表单方法

//序列化表单function getSearchFormDataJson($from) {var data = $from.serializeObject();return JSON.stringify(data);}
