XMLHttpRequest response text is empty in a strange situation

JavaScript
1

I want to get subtitles from yifysubtitle，so i wrote a script to do that. When I test it in a single file, like this:

var web=new XMLHttpRequest();
web.open("GET","http://www.yifysubtitles.com/movie-imdb/tt0816692",true);
web.send(null);
web.onreadystatechange=function(){
    if (web.readyState==4){
        var str=web.responseText;
        var subtitle=str.split(/class="reply-rating"/);
        var i;
        var subtitlelist="";
        for(i=1;i<subtitle.length;i++){
            var check=subtitle[i].split(/flag flag-cn/);
            if(check.length>1){
                var rating1=subtitle[i].split(/title="rating">/);
                var rating2=rating1[1].split(/<\/span>/);
                var rating=rating2[0];
                var href1=subtitle[i].split(/href="/);
                var href2=href1[1].split(/">/);
                var href=href2[0];
                subtitlelist=subtitlelist+rating+"  http://www.yifysubtitles.com"+href+"\n";
            }
        }
        alert(subtitlelist);
    }
}

it works fine, and I get what I want. But when I try to put that code in a JavaScript file that already has another XMLHttpRequest named xhr，I get empty response text. Are there any restrictions on using two XMLHttpRequests in one file? How can I fix this?
