正则表达式模式，用于检查字符串中每个单词的第一个字母，如果它是Javascript中的大写字母

Question

for example my string is Foo Bar. this string should match the pattern.

if the string is Foo bar. the string should not match.

if the string is Foo Bar Foobar the string should match

if the string is Foo. it should also match.

so far I only have this pattern

 (^[A-Z]{1}.*(\s)?$)+

Basically I will only accept a string where each First letter of each word is Uppercase

Answer 1

我会看看你的字符串是否与以下内容不匹配：

/\b[a-z]/

Answer 2

You can try to use this regex:

^(\b[A-Z]\w*\s*)+$

Answer 3

我以前用这个：

#(\s|^)([a-z0-9-_]+)#i
