I need a regex for javascript that includes a-z, A-Z, and spaces
我需要一个包含a-z、a-z和空格的javascript正则表达式
For example, the string "Bob says Hi" would be accepted, but not "There were 4 clowns"
例如，字符串“Bob says Hi”将被接受，而不是“There were 4小丑”
The closest I've gotten is /^[a-zA-Z]+$/ which includes a-z and A-Z but not spaces.
最近的我已经是/ ^[a-zA-Z]+ /美元,包括a - z、a - z但不空格。

or just /\w+$/ if you also want 0-9 and underscores (\w stands for "word character", usually [A-Za-z0-9_]). But your recent edit indicates that you dont want 0-9, so use one of the first 2 above.
或者只是/\w+$/如果你也想要0-9和下划线(\w代表“文字字符”，通常是[A-Za-z0-9_])。但是你最近的编辑表明你不需要0-9，所以使用上面的前2个。

/[a-zA-Z ]+/
If you're trying to see if a string consists entirely of a-z, A-Z and spaces, then you can use this:
