在正则表达式模式[a-zA-Z] *中添加空格字符 [英] Add space character to regular expression pattern [a-zA-Z]*

问题描述

我正在使用<f:validateRegex pattern="[a-zA-Z]*"/>来确保输入的值仅包含字母，它可以正常工作，但不允许在字符串中留空格.
如何在上述模式中加入空格字符? 预先感谢.

I'm using <f:validateRegex pattern="[a-zA-Z]*"/> for ensuring that entered values contain alphabet only, it is working fine but it is not allowing to take space in the string.
How can i incorporate space character in above pattern? Thanks in advance.

推荐答案

只需在正则表达式中添加空格.

Simply add the space to the regex.

<f:validateRegex pattern="[a-zA-Z ]*"/>

如果您需要任何空格，而不仅仅是空格，请与\s交换空格.

If you wanted any whitespace, not just space, swap the space with \s.

<f:validateRegex pattern="[a-zA-Z\\s]*"/>
