how to check for a special character "<" or ">" in a input in javascript?

Question

Trying to check for < or > in the user input in javascript. any idea what the regular expression wud be? This regex does not seem to work

 var spclChar=/^[<>]$/;
        if(searchCriteria.firstName.match(spclChar)){
            return true;
        }else {
            return false;
        }

your regex is searching for a `<` at the START of the string, or a `>` at the END of the string. if you want them ANYWHERE in the string, then dump the `^` and `$`. — Marc B, Aug 24 '15 at 19:21

You can use a character class like this:

[<>]
or
[><]

Working demo

Btw, you have useful comments in your question like Sam's

/[<>]/
