如何在此正则表达式中包含 - 和 '？

Question

I have a this regular expression below for some input name fields. How do I include an apostrophe and a hyphen in this?

InputField("tFName", /^[a-zA-Z-\-\ ]+$/);

Answer 1

Hyphen is already included (twice), you can add the apostrophe by just editing it into the character class:

/^[a-zA-Z-\-\ ']+$/

You can rewrite it to look like this, so that there's no need to escape the hyphen and it's only included once:

/^[a-zA-Z '-]+$/

Answer 2

Try this:

"abc'def ghi-jkl mno-pq'rst".match(/^[\w\s-']+$/)

• \\w for any letter
• \\s for space
• - for hyphen
• ' for apostrophe
