Regular expression for only characters a-z, A-Z
javascript, jquery, regex
Solution
/^[a-zA-Z]*$/
Change the `*` to `+` if you don't want to allow empty matches.
References:
Character classes (`[...]`), Anchors (`^` and `$`), Repetition (`+`, `*`)
The `/` are just delimiters, it denotes the start and the end of the regex. One use of this is now you can use modifiers on it.
Problem
I don't know how to create a regular expression in JavaScript or jQuery. I want to create a regular expression that will check if a string contains only characters between a-z and A-Z with any arrangement. EDIT When I tried to make regex ``` /^[a-zA-Z\s]+$/ ``` to accept white spaces as well. It is not working. What could be the mistake? I am testing my regular expression at JavaScript RegExp Example: Online Regular Expression Tester.
