Is there a way where I can find if any of these strings are entered. I want to see if the user entered "Mr", "Miss", "Mrs" or "Ms".

I have tried /^(Miss|Mr|Mrs|Ms)$/ but to no avail.

The context is that I have a text box that users should enter their title into.

I want users to only Enter "Mr", "Miss", "Mrs", and "Ms". If they enter anything else, throw an error.

    Dr, Rev, Sir, Lord, Dame, Lady... This may be one of those questions where a little more context could help – Liath Sep 09 '14 at 07:36

  • Here's a great tool for testing regexes - http://derekslager.com/blog/posts/2007/09/a-better-dotnet-regular-expression-tester.ashx – Liath Sep 09 '14 at 07:36
  • I'm using a RegularExpressionValidator in ASP.net to check whether users entered their title right. If Miss/Mr/Mrs/Ms was not entered then throw an error. UMM is there a way to do an inverse of that regex I did? – helloGoodDay Sep 09 '14 at 07:56

    Use a drop down menu instead of a text box. – jscs Sep 09 '14 at 08:45
  • @JoshCaswell hey Josh, thanks for replying. The thing is I get a horrendous problem that I couldn't solve, even with looking at lots of solutions if I implement a drop down list So I've reverted to a textbox – helloGoodDay Sep 09 '14 at 09:13
  • Did you try [without the delimiters](http://stackoverflow.com/a/13626639/3110638) `/` ? – Jonny 5 Sep 09 '14 at 10:34
  • That's like saying that your lawnmower won't start, so you're cutting the grass with a pair of scissors. Fix your lawnmower. This is going to be a _terrible_ user experience -- reading your mind to figure out _exactly_ which honorifics you planned for and _exactly_ how you spelled them (no period/full stop, e.g., which should be present in American English but perhaps not other dialects). – jscs Sep 09 '14 at 18:57
  • @Jonny5 You are a legend. Thank you so much (Y) I wish i can give you reddit gold – helloGoodDay Sep 10 '14 at 03:18
  • @JoshCaswell I agree, i've been searching for the answer for 2 days and I just can't seem to get it. I really regret doing this method, but it's the only way that works. – helloGoodDay Sep 10 '14 at 03:19
  • You could probably ask about your problems with the combo box here too. – jscs Sep 10 '14 at 03:45

  • If you limit the title like that, you'll get complaints from customers. People with titles tend to be picky about them. It's almost like they have a sense of... [puts on sunglasses] ...entitlement. – Matt Gibson Sep 10 '14 at 09:40
  • @MattGibson Oh so true oh so true – helloGoodDay Sep 10 '14 at 10:08

Maybe all you need to do is to get rid of the $ at the end and replace it with a \b so that if I enter 'Mr John' you can recognize it.

A more compact version of your regex might be:

/^(M(?:is)?s|(?:Mrs?))/

Have look at this demo.

As mentioned in another answer's comment, if the search string can lie in the middle of the string as well then remove ^ from pattern.

/^(Mr|Mrs|Mr|Dr|Er)\.[A-Za-z]+$/;

Here ^(Mr|Mrs|Mr|Dr|Er) will check for the starting of the string.

\. will allow a dot after Title

And then there can be any word or letter so array of words.
