推荐答案

1.您可以使用验证表达式检查日期:

1. you can use the validation expression to check for dates:

<br />
var Year="^[0-9]{4}

";<br />

";<br />

至于范围，我认为您应该使用范围验证器或自定义验证器进行检查.

如果您想要像2011-2012这样的值范围，那么正则表达式将是:

as for the range i think you should use a range validater or custom validater to check for that.

in case you want the range like value like 2011-2012 then regex will be:

<br />
var Year="^[0-9-]{9}

";<br />

";<br />
