How to Create a Regular Expression in ReactJS

Question

I want to create a regular expression that starts with two letters and is followed by 6 digits only and compare it with a string useState that I have.

How can I do that in ReactJs?

Answer 1

You may try using the pattern ^[az]{2}[0-9]{6}$ , for example:

 var inputs = ["AB123456", "A123456", "AB12345"]; for (var i=0; i < inputs.length; ++i) { if (/^[az]{2}[0-9]{6}$/i.test(inputs[i])) { console.log("MATCH => " + inputs[i]); } else { console.log("NO MATCH => " + inputs[i]); } }

Note that I am running the above regex using the case insensitive /i flag.
