The code is as follows:

// 改进版 _ar
function _ar2(s, target, feedback, param, methods){
 var url, method;
 var params = {};
 if( (s instanceof jQuery) && s.attr("tagName")=='VFORM') {
  url  = s.attr('action');
  method = s.attr('method');
  params = param || $('input, textarea, select',s).serialize();
 }else if( (s instanceof jQuery) && s.attr("tagName")=='FORM') {
  url  = s.attr('action');
  method = s.attr('method');
  params = param || s.serialize();
 }else if(typeof(s)=='string'){
  url  = s; // http://...
 }

 url = url || '';
 method = method || methods || 'GET';
 params = param ? param : params;
 jQuery.ajax({
  type: method,url:url,data:params,
  beforeSend: function(){
   //jQuery.jGrowl('数据读取中 请稍候..', {  header: '提示', theme: 'blue'});
  },
  success: function(data) {
   //data = jQuery.trim(data).replace(/[ntr]/gi,'');
   if(feedback){
    eval(feedback '('' escape(data) '')');
    return;
   }else{
    if(data){
     if(target){
      jQuery(target).html(data);
      jQuery.jGrowl('页面请求完毕.', {  header: '提示', theme: 'green', 'life': 100});
      return;
     }
    }else{
     lg('no feedback');
     jQuery.jGrowl('服务器无返回信息.', {  header: '提示', theme: 'blue'});
     return;
    }
   }
   jQuery.jGrowl(data, {  header: '提示', theme: 'blue'});
  },
  error: function (e){
   var s = e.status;
   switch(s) {
    case 404:
     jQuery.jGrowl('请求的页面无法找到. 请联系系统管理员.', {  header: '提示', theme: 'blue'});
    break;
    case 500:
     jQuery.jGrowl('服务器错误[500]. 请联系系统管理员.', {  header: '提示', theme: 'blue'});
    break;
    default:
     //log('unknow error');
     lg(s);
     jQuery.jGrowl('未知错误. 请联系系统管理员.', {  header: '提示', theme: 'blue'});
   }
  }
 });
}

注意：jQuery.jGrowl是jquery的一个弹窗提示的插件，提示完成自动消失，用起来很方便，google一下就知道了。另外至于使用方法，返回数据是我们公司约定好的一个格式，方便使用而已。
