新手写的插件，大家帮忙指点下吧

本人前天晚上开始学jquery，学习的方式就是不停的查Api和到本版咨询。
为了演练选择器及其他相关的用法，写了个轻量级表单验证插件：
请jquery高手帮忙指点或优化下。

使用如下：
<script language="javascript">
$(function(){    
    $(":text[name='username']").check("chn","必须填写中文!");
    $(":text[name='english']").check("eng","必须填写e文!",false);
    $(":text[name='ok.number']").check("eq,eng","值为英文且等于english文本框值",true,$(":text[name='english']").val());    
    $(":input[name='selectname']").check("rq","没有选择");
    $(":radio[name='radioname']").check("rq","没有选择");
    $(":checkbox[name='box']").check("rq","没有选择");
    $("form[name='form1']").check();
})
</script>
参数说明：
$(":text[name='username']") 表单对象名
chek() 函数
第一个参数为验证类型（多重验证用，号隔开），
第二个参数为提醒信息
第三个参数为是否必填，可选，无值即为必填
第四个参数为参考值，可选，用来进行对比

默认验证事件为blur和submit

经多次测试，暂没发现bug
未加入ajax验证



插件代码如下：

我先收藏。最近我也刚写了个小验证函数。只是里面的结构太乱了。
