让回调函数 showResponse 也带上参数（转）

function demo(url,paras,updateElemID){
     var myAjax = new Ajax.Request(
     url,
     {
         method: 'post',
         parameters: paras,
      onComplete:function(originalRequest){showResponse(originalRequest,updateElemID)}
     });
    }
    function showResponse(originalRequest,elemID){
        var html = originalRequest.responseText;
         $(elemID).innerHTML = html;
    }
