修正ueditor不兼容IE的单图片BUG

找到源码中 simpleupload 模块 ，搜索 initUploadBtn，修改其中的一段代码为如下所示

domUtils.on(input, 'change', function(){
function showErrorLoader(title){
if(loadingId) {
var loader = me.document.getElementById(loadingId);
loader && domUtils.remove(loader);
me.fireEvent('showmessage', {
'id': loadingId,
'content': title,
'type': 'error',
'timeout': 4000
});
}
}
function createXMLHttpRequest() {
if(window.XMLHttpRequest){
return new XMLHttpRequest();
} else {
var names=["msxml","msxml2","msxml3","Microsoft"];
for(var i=0;i<names.length;i++){
try{
var name=names[i]+".XMLHTTP";
return new ActiveXObject(name);
}catch(e){
}
}
}
return null;
}

if(!input.value) return;
var loadingId = 'loading_' + (+new Date()).toString(36);
var params = utils.serializeParam(me.queryCommandValue('serverparam')) || '';

var imageActionUrl = me.getActionUrl(me.getOpt('imageActionName'));
var allowFiles = me.getOpt('imageAllowFiles');

me.focus();
me.execCommand('inserthtml', '<img class="loadingclass" id="' + loadingId + '" src="' + me.options.themePath + me.options.theme +'/images/spacer.gif" title="' + (me.getLang('simpleupload.loading') || '') + '" >');

/* 判断后端配置是否没有加载成功 */
if (!me.getOpt('imageActionName')) {
errorHandler(me.getLang('autoupload.errorLoadConfig'));
return;
}
// 判断文件格式是否错误
var filename = input.value,
fileext = filename ? filename.substr(filename.lastIndexOf('.')):'';
if (!fileext || (allowFiles && (allowFiles.join('') + '.').indexOf(fileext.toLowerCase() + '.') == -1)) {
showErrorLoader(me.getLang('simpleupload.exceedTypeError'));
return;
}

var formData = new FormData();
var file=input.files[0];
formData.append(me.options.imageFieldName, file);

var xhr = createXMLHttpRequest();
xhr.open('POST', imageActionUrl + (imageActionUrl.indexOf('?') == -1 ? '?':'&') + params, true);
xhr.onreadystatechange = function(){

//响应完成且响应正常
if (xhr.readyState == 4)
{
if (xhr.status == 200)
{
json = (new Function("return " + xhr.responseText))();
link = me.options.imageUrlPrefix + json.url;
if(json.state == 'SUCCESS' && json.url) {
loader = me.document.getElementById(loadingId);
loader.setAttribute('src', link);
loader.setAttribute('_src', link);
loader.setAttribute('title', json.title || '');
loader.setAttribute('alt', json.original || '');
loader.removeAttribute('id');
domUtils.removeClasses(loader, 'loadingclass');
} else {
showErrorLoader && showErrorLoader(json.state);
}

}
else
{
showErrorLoader && showErrorLoader(me.getLang('simpleupload.loadError'));
}
form.reset();
}

};

xhr.send(formData);

});
