调用webservice传参的问题

 var xmlObj=null;
  var AccounrAddress = "http://210.***.***.***/service/service.asmx?";
  var PythonAddress = "http://210.***.***.***/proxy.py?url=";

         //创建
    function CreatXMLHttpRequest()
    {
        if(window.XMLHttpRequest)
        {
            xmlObj=new XMLHttpRequest();
        }
        else if(window.ActiveXObject)
        {
            xmlObj=new ActiveXObject("Microsoft.XMLHttp");
        }
    }  

function aa(tel)
{
    var result = "";

    var url=PythonAddress + EncodeUtf8(AccounrAddress + "GetIllegalListByTelNumber&strTelNumber="+tel);
            
    CreatXMLHttpRequest();  
             
    //处理返回信息函数
    xmlObj.onreadystatechange = function()
    {
          alert(xmlHttpRequest);
          //xmlhttp.readyState 0:未初始化  1:正在加载  2:已经加载完成  3:正在和服务器交互 
     
              if(xmlHttpRequest.readyState == 4)
              {
                  if(xmlHttpRequest.status == 200)
                  {
                          if(xmlObj.responseText=="0")
                      {
                            return null;
                      }
                      else
                      {                          
                              result = xmlObj.responseText;
                      } 
                  }
                  else
                  {   
                      window.alert("请求页面异常");   
                  }   
              } 
        }
     try
     {
              xmlObj.open("GET",url,false); 
              xmlObj.send(null); 
      }
      catch(e)
      {
        alert(e);
      }       
      return result;
}

var url=PythonAddress + EncodeUtf8(AccounrAddress + "GetIllegalListByTelNumber&strTelNumber="+tel);
encodeURIComponent转下码，然后到服务器端再转下就回来了
var url=PythonAddress + encodeURIComponent(AccounrAddress + "GetIllegalListByTelNumber&strTelNumber="+tel);

将EncodeUtf8换成encodeURIComponent，然后在后台用Decode转码
