How to Specify single quote in regular expression

Here is my regular expression . I want to include single quotes (') within the characters such as (O'Neal Nickel). Here is my regular expression allowing letters and spaces and full stops(.) and (-) hyphens

 /^[A-Za-z\/\s\.-]+$/;

/^[A-Za-z\/\s\.'-]+$/; Or did I get your question wrong?

Try this:

/^[A-Za-z\/\s\.'\-]+$/; 

You do not need to backslash/escape the single quote. Doing so will cause Safari to disallow single quote marks instead of allowing them.

var testName=/^[A-Za-z\/\s\.'-]+$/; var name= $("#name").val(); if(testName.test(name) == false || name == "") {} 

This is a code I used to check name

/^[A-Za-z\/\s\.'-]+$/

@Urasquirrel - you asked for detailed explanation and I know that whenever I see questions like this, I want the same thing!!

^ - beginning of the string [ - allowed characters are contained in the square brackets A-Z - uppercase A to Z a-z - lowercase a to z \/ - escaped forward slash \s - whitespace \. - escaped period ' - single quote - - a dash ] - end of square brackets + - ONE of more of the allowed characters contained in the square brackets $ - end of string 

is a great place to test different RE patterns with different strings and different languages. there are other sites that do similar
