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.

• javascript
• jquery

• A few too many "val" ? val[] and val() – mplungjan Commented Dec 22, 2011 at 15:43

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).

Don't get confused by pipe. Must end each expression

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

I had similar problem and my solution was to write it like:

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

Try this, it's a little more strict.

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