如何让ajaxfileupload.js支持IE9，IE10，并可以传递多个参数？
1、如何让ajaxfileupload.js支持IE9、IE10？
打开ajaxfileupload 文件，找到下面的代码。
if(window.ActiveXObject) {
var io = document.createElement('');
if(typeof uri== 'boolean'){
io.src = 'javascript:false';
}
else if(typeof uri== 'string'){
io.src = uri;
}
}if(window.ActiveXObject) {
if(jQuery.browser.version=="9.0" || jQuery.browser.version=="10.0"){
var io = document.createElement('iframe');
io.id = frameId;
io.name = frameId;
}else if(jQuery.browser.version=="6.0" || jQuery.browser.version=="7.0" || jQuery.browser.version=="8.0"){
var io = document.createElement('');
if(typeof uri== 'boolean'){
io.src = 'javascript:false';
}
else if(typeof uri== 'string'){
io.src = uri;
}
}
}2、如何让ajaxfileupload.js可以在文件上传的同时传递多个台数。
找到以下代码：
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);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.tag_name, s.tag_link, s.tag_sort, s.tag_status, s.tag_id);接着找到：
createUploadForm: function(id, fileElementId, tag_name, tag_link, tag_sort, tag_status, tag_id)//增加tag_name, tag_link, tag_sort, tag_status, tag_id
{
//create form
var formId = 'jUploadForm' + id;
var fileId = 'jUploadFile' + id;
//--增加以下内容
var tagNameId = 'tag_name' + id;
var tagLinkId = 'tag_link' + id;
var tagSortId = 'tag_sort' + id;
var tagStatusId = 'tag_status' + id;
var tagIdId = 'tag_id' + id;
//--end
var form = $('');
var oldElement = $('#' + fileElementId);
var newElement = $(oldElement).clone();
//--增加以下内容
var tagNameElement = '';
var tagLinkElement = '';
var tagSortElement = '';
var tagStatusElement = '';
var tagIdElement = '';
//--end
$(oldElement).attr('id', fileId);
$(oldElement).before(newElement);
$(oldElement).appendTo(form);
//--增加以下的内容
$(tagNameElement).appendTo(form);
$(tagLinkElement).appendTo(form);
$(tagSortElement).appendTo(form);
$(tagStatusElement).appendTo(form);
$(tagIdElement).appendTo(form);
//--end
//set attributes
$(form).css('position', 'absolute');
$(form).css('top', '-1200px');
$(form).css('left', '-1200px');
$(form).appendTo('body');
return form;
},修改完后，如何使用？
$.ajaxFileUpload({
url:web_url,
secureuri:false,
//以下为增加的传递参数
tag_name:tag_name,
tag_link:tag_link,
tag_sort:tag_sort,
tag_status:tag_status,
tag_id:tag_id,
//--end
fileElementId:result[0],
dataType: 'json',
success: function (data,status){}
//以下省略
OK，done.

createUploadIframe: function(id, uri)

//create frame
var frameId = 'jUploadFrame' + id;
if(window.ActiveXObject) {
// var io = document.createElement('');
// if(typeof uri== 'boolean'){
// io.src = 'javascript:false';
// }
// else if(typeof uri== 'string'){
// io.src = uri;
// }
//fix ie9 and ie 10-------------
