Javascript regexp using val().match() method

Question

I'm trying to validate a field named phone_number with this rules:

the first digit should be 3 then another 9 digits so in total 10 number example: 3216549874

or can be 7 numbers 1234567

here i have my code:

        if (!($("#" + val["htmlId"]).val().match(/^3\d{9}|\d{7}/)))
            missing = true;

Why doesnt work :( when i put that into an online regexp checker shows good.

Answer 1

You should be using test instead of match and here's the proper code:

.test(/^(3\d{9}|\d{7})$/)

Match will find all the occurrences, while test will only check to see if at least one is available (thus validating your number).
