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> 演示:http://www.2881.com/qq/
