解决方案 »

  1.   

    HTML的？
    <head>里面+句<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
      

  2.   

            function   GetData(value) 
            { 
                    createHTTP();
                    xmlhttp.setRequestHeader('Content-Type', 'text/html;charset=gb2312');
                    xmlhttp.onreadystatechange   =   StateChange; 
                    xmlhttp.open("GET",   value,   false);                 xmlhttp.send(); 
            } 
      

  3.   

    真是晕倒，byte2string 是处理GB编码的函数 www.google.cn本身就是utf-8
    因此只接用xmlhttp.responseText就可以了
