    这段程序的方法是利用XMLHTTP来读取腾讯网站的相应HTML代码获取QQ的头像,根据这个想法,我们还可以抓取很多其他网站的信息,如天气预报、新闻等等。


    <script language="javascript">

    <!--

    function getFaceImg(QQcode)

    {

    var Re=new RegExp("^[1-9]{1}\\d+$","g");

    if (!QQcode||!Re.test(QQcode)) return;

    var URL="http://search.tencent.com/cgi-bin/friend/oicq_find?oicq_no="+QQcode;

    var http=new ActiveXObject("Microsoft.XMLHTTP");

    http.open("GET",URL,false,"","");

    http.setRequestHeader("CONTENT-TYPE","text/html; Charset=gb2312");

    http.send();


    if (http.status!=200) return;


    var webStr=http.responseText;

    Re=new RegExp("\"(http://img.tencent.com/face/[^\"]+)\"","ig");

    if (Re.test(webStr))

    return "<a href=\"http://search.tencent.com/cgi-bin/friend/user_show_info?ln="+QQcode+"\" target=_blank title=\"QQ:"+QQcode+"\"><img src=\""+RegExp.$1+"\" width=16 height=16 border=0></a>";


    http=null;

    }


    document.write("我的QQ状态:"+getFaceImg("44723461"));

    //-->

    </script>
