jQuery - check whether string contains numeric value

Question

How to check whether a string contains any numeric value by jquery?

I search through many examples but I only get the way to check for a number, NOT number in a STRING. I am trying to find something like $(this).attr('id').contains("number");

(p/s: my DOM id will be something like Large_a (without numeric value) , Large_a_1 (with numeric value), Large_a_2, etc.)

What method should I use?

You could use a regular expression:

var matches = this.id.match(/\d+/g);
if (matches != null) {
    // the id attribute contains a digit
    var number = matches[0];
}
