[英]Blank Regular Expression
Using Cforms
and adding some validation in, thought i'd throw in the Honeypot method as well. 使用
Cforms
并添加一些验证,以为我也会抛出Honeypot方法。 With cforms
it allows you to add a Regex
into a field, but I have been trying to figure out how to create a "blank" regex. 使用
cforms
它允许您将正则Regex
添加到字段中,但是我一直在尝试找出如何创建“空白”正则表达式的方法。
the best I have so far is to put a space into the field then use this regex: ^\\s
This works perfectly well, but just out of pure interest, is there a pure blank version, so that if ANY character is typed in then it won't validate. 到目前为止,我最好的方法是在该字段中放置一个空格,然后使用此正则表达式:
^\\s
这可以很好地工作,但是出于纯粹的兴趣,是否有一个纯空白版本,因此如果在其中键入任何字符,则它不会验证。
Thanks 谢谢
Like this? 像这样?
^$
(start+end with nothing in between). ^$
(开始+结束,中间没有任何内容)。
只是添加了另一种做相同事情的方式: .{0}
