找到一个正则表达式来检查字母,汉字和斜杠(/) [英] find a regular expression to check letter,chinese character and slash(/)
问题描述
当我输入姓名时,我想查看用户的输入值,如果他的输入是英文名字,则该名称只包含字母,并且必须用斜杠(/)分隔,例如:
GeorgeBush,George Bush,GeorgeBush /,dsfsdf /
是错误的;乔治/布什,fdfd / fdfd / sds 是对的。
i找到一个这样的正则表达式: / ^ [a-zA-Z\\\一-\\\龥\ /] {1,20} /
。但是它不能检查 fsfd /
或 / fdsf
。请给我一些建议。谢谢!
i want to check users' input value when he input his name, if his input is a English name, the name only contains letters and must be divided with slash(/), example:
GeorgeBush, George Bush,GeorgeBush/, dsfsdf/
are wrong; George/Bush, fdfd/fdfd/sds
are right.
i have find a regular expression like this:/^[a-zA-Z\u4E00-\u9FA5\/]{1,20}/
. But it can't check fsfd/
or /fdsf
. please give me some suggestions. thanks!
推荐答案
不清楚你想要什么,也许这样:
Not clear exactly what you want, maybe this:
^(?=.{1,20}$)[a-zA-Z\u4E00-\u9FA5]+(?:\/[a-zA-Z\u4E00-\u9FA5]+)?$
