ueditor跨域上传，虽然图片上传成功，但是提示上传错误，图片不展示的解决方法

ueditor.all.js中查找关键字 

domUtils.on(iframe, 'load', callback);

然后替换

//domUtils.on(iframe, 'load', callback);
//form.action = utils.formatUrl(imageActionUrl + (imageActionUrl.indexOf('?') == -1 ? '?':'&') + params);
//form.submit();

var formdata = new FormData(form);
var arr,reg=new RegExp("(^| )_token=([^;]*)(;|$)");

var myForm = document.getElementById("myForm");
var xhr= new XMLHttpRequest();
xhr.open("POST", me.getOpt('serverUrl')+'?action=uploadimage', true);
xhr.onreadystatechange = function() {
    if (xhr.readyState === 4)
        if ((xhr.status >=200 && xhr.status < 300) || xhr.status == 304)
            alert(xhr.responseText);
}
xhr.send(formdata);

xhr.onreadystatechange = function () {
    if(xhr.readyState == 4) {
        console.log(xhr.responseText);
        var response = JSON.parse(xhr.responseText);
        if(response.success ){
            loader = me.document.getElementById(loadingId);
            loader.setAttribute('src', response.data.url);
            loader.setAttribute('_src', response.data.url);
            loader.setAttribute('title', response.data.title || '');
            loader.setAttribute('alt', response.data.original || '');
            loader.removeAttribute('id');
            domUtils.removeClasses(loader, 'loadingclass');
        }else
        {
            showErrorLoader && showErrorLoader(json.state);
        }
    }
}

就可以完美的解决问题了。
