I want to make a regular expression that only accepts lowercase letters and does not allow uppercase letters and does not allow white space. So far I have this:

\S[a-z]

Please help me, I dont know how make that I'm working on it in reactJS with the ant library, and I want to add a rule to my form but the regular expression doesn't work for what I really need

CodePudding user response：

/^[a-z] $/

^ - start of string

$ - end of string

[] - Character Classes

you can use for one or more OR * zero or more
