Javascript 如何在jquery中对规则进行分组

嗨，我有一个简单的问题。下面是我的代码，我以非常相似的方式使用了三次ajax，唯一改变的是传递的数据和目标的id。有没有一种方法可以将这些指令组合成一个简单的指令？ 谢谢 D

使用对象和控件结构：

var fields = {firstname:1, lastname:1, phone:1};
for (field in fields) {
  $.ajax({
    type:"GET",
    url: "autocomplete.asp",
    data: "fld=" + field + "&email=" + request_email,
    beforeSend: function() {
      $('#fld_'+field).addClass('ac_loading');
    },
    success: function(msg) {
      $('#fld'+field).val(msg);
      $('#fld'+field).removeClass('ac_loading');
    }
  });
}

尝试：

非常感谢。这个解决方案是完美的。

var fields = {firstname:1, lastname:1, phone:1};
for (field in fields) {
  $.ajax({
    type:"GET",
    url: "autocomplete.asp",
    data: "fld=" + field + "&email=" + request_email,
    beforeSend: function() {
      $('#fld_'+field).addClass('ac_loading');
    },
    success: function(msg) {
      $('#fld'+field).val(msg);
      $('#fld'+field).removeClass('ac_loading');
    }
  });
}

$('#fld_email').focusout(function() {
    var request_email = $(this).val();
    processAjax("fld=firstname&email="+request_email, '#fld_firstname');
    processAjax("fld=lastname&email="+request_email, '#fld_lastname');
    processAjax("fld=phone&email="+request_email, '#fld_phone');
});

function processAjax(data, id){
    $.ajax({type:"GET",
           url: "autocomplete.asp",
           data: data,
           beforeSend: function(){$(id).addClass('ac_loading');},
           success: function(msg){$(id).val(msg).removeClass('ac_loading');}
    });   
}
