I'm use easyui tabs load html content:

contents.tabs('add',{
    title: title,
    href: href,
    closable: true,
    extractor:function(data){
        console.log(data);
        return data;
    }           
});

sometime I maybe got a 404, 500 response, but the response error message is not display in the new window. The tab window always show loading style.

So I try to find a onLoadError event to catch this error in office manual: http://www.jeasyui.com/documentation/tabs.php , but not exists. Please tell me how to do let me exit the loading status.
