regex digits formatting

Question

I want to use regex specifically! to check if a mobile number contains 9 or more digits. I am a little unsure as to how to format this exactly.

I want to check inside an if statement like the below

if(mob >= (.{9})

This is clearly not correct, any help would be great

Please add sample data showing what these mobile numbers look like. — Tim Biegeleisen

Use test with the regex pattern ^\+?[0-9]{9,}$:

var number = "+123456789";
if (/^\+?[0-9]{9,}$/.test(number)) {
    console.log("MATCH");
}

You need to check of numbers not for all the characters. And also use test() to check if string matches regex or not.

const testMob = str => /^\+?[0-9]{9,}$/.test(str);

console.log(testMob('+123456789')) //true
console.log(testMob('+1234567890')) //true
console.log(testMob('+133333'))  //false

More info from OP, update to ^\+*(\d){9,}$ to include the optional plus sign

@JasonB That pattern is incorrect, and would allow for any number of leading +. I'm pretty sure the OP only expects at most one +.

Right you are, should be ? instead of *. ^\+?(\d){9,}$
