Matching exactly 10 digits in Javascript [duplicate]

Answer 1

You can try with test() function that returns true/false

var str='0123456789';
console.log(/^\d{10}$/.test(str));

OR with String#match() function that returns null if not matched

var str='0123456789';
console.log(str.match(/^\d{10}$/));

Note: Just use ^ and $ to match whole string.

Answer 2

You can try this :

var str = "0123456789";
var pattern = new RegExp("^[0-9]{10}$");
pattern.test(str);

Answer 3

You can use this:

var pattern = /^[0-9]{10}$/;
