成功完成了官网Demo中的小测试：

PS 可选项的验证方法：
http://my.oschina.net/duanlijun/blog/9951
[4] rules( "add", rules )
 返回：Options

参数"add" 类型：String

参数 rules 类型：Options 要添加的规则，与validate方法中的验证规则一致。

说明：添加规则到匹配的表单元素，返回该元素的所有验证规则，需要先执行$("form").validate()。在rules中也可以添加用户自定义的消息对象。

Js代码

$("#myinput").rules("add", {

required: true,
minlength: 2,
messages: {
required: "Required input",

minlength: jQuery.format("Please, at least {0} characters are necessary")

}
});

[5] rules( "remove", [rules] )
 返回：Options

参数"remove" 类型：String

参数 rules (Options)
类型：Options 用空白符分割的验证规则。只操作通过rules选项或rules("add")指定的验证规则。

说明：从第一个匹配的表单元素中移除指定的验证规则，并返回该元素所有的验证规则。

Js代码

$("#myinput").rules("remove");

$("#myinput").rules("remove", "min max");
