使用 jQuery 检查正则表达式

我知道有 jQuery 验证插件。但我不需要那么广泛的东西。

我想要做的就是让 jQuery 检查名称文本框：

<input type="text" name="name" id="name" />

以确保它至少有 2 个字符

，并且

我希望 jQuery 检查电话文本框（与名称文本框相同，name="phone" 和 id= “phone”），以确保它只包含数字，无论有多少个数字。

最后，只有在这不太难完成的情况下，我希望 jQuery 验证电子邮件地址以检查并确保其中包含字符“@”。

这太难做到了吗？

谢谢，阿米特

I know there's the jQuery validation plugin. But I don't need something that extensive.

All I want to do is have jQuery check a name text box:

<input type="text" name="name" id="name" />

To make sure that it has at least 2 characters

AND

I want jQuery to check a phone text box (identical to the name text box, name="phone" and id="phone"), to make sure that it only contains numbers, doesn't matter how many numbers.

Finally, and this is only if this is not too hard to accomplish, I want jQuery to validate the email address to check and make sure that it has the character '@' in it.

Is this too hard to do?

Thanks,
Amit
