Javascript regex for alphabetic characters and spaces?
提问by DontTurnAround
I need a regex for javascript that includes a-z, A-Z, and spaces
我需要一个包含 az、AZ 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 say Hi”将被接受，但不能接受“There was 4 clowns”
The closest I've gotten is /^[a-zA-Z]+$/which includes a-z and A-Z but not spaces.
我得到的最接近的是/^[a-zA-Z]+$/包括 az 和 AZ 但不包括空格。

/^[A-Za-z ]+$/or /^[A-Za-z\s]+$/
/^[A-Za-z ]+$/或者 /^[A-Za-z\s]+$/

or just /\w+$/if you also want 0-9 and underscores (\w stands for "word character", usually [A-Za-z0-9_]). But your recent edit indicates that you dont want 0-9, so use one of the first 2 above.
或者只是/\w+$/如果您还需要 0-9 和下划线（\w 代表“单词字符”，通常为[A-Za-z0-9_]）。 但是您最近的编辑表明您不想要 0-9，因此请使用上面的前 2 个之一。

You can use this to match a sequence of a-z, A-Z and spaces:
您可以使用它来匹配一系列 az、AZ 和空格：
/[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:
如果您想查看字符串是否完全由 az、AZ 和空格组成，则可以使用以下命令：
/^[a-zA-Z ]+$/

For other regex symbols, there are tons of references on the internet. This is the one I have bookmarked and look at regularly: http://www.javascriptkit.com/javatutors/redev2.shtml.
