2 个单词、非数字和一个空格的正则表达式

Question

I am trying to build a javascript regex that allows users to enter 2 words only, non-numeric, and only one space between them. I have been trying this one: ^\w+\s*\w+?$ but don't know how to avoid numbers.

Answer 1

You can try this:

([A-Za-z]+)\s([A-Za-z]+)$

Answer 2

If the 2 words only use the alphabets without any special characters.

You can use the simplest one. /^([az]+)\s+([az]+)(\s*)$/gi

 [a-z]+ tells any character in the alphabet with quantifier of one or more
 \s* -> is a space with a quantifier of zero or more
  i -> on the last part tells case-insensitive matching

 let a = 'my Word'; let b = 'oneWord'; let c = 'using three words'; let d = 'onewordwithspace '; let e = 'my wordwithSpace '; let regEx = /^([az]+)\s+([az]+)(\s*)$/gi; console.log((regEx.test(a))); // true console.log((regEx.test(b))); // false console.log((regEx.test(c))); // false console.log((regEx.test(d))); // false console.log((regEx.test(e))); // true
