regular expression in Java script to test for one or many digits

I need to check an input string to see if it has at least one number in it. Example: Love4You Or : LotsOfNumbers012344.
Can someone tell me how to check for one or many digits using a Java Script regular epression?

This is what I have tried and it is not working
var oneOrManyDigits = new RegExp("(\d+)");

and this one also does not work : new RegExp("(^\\d+$)");

You were close with your original attempt. There are many ways of doing this but \d+ is the most succinct.

Try this
var inpstr = 'LotsOfNumbers012344';
res = inpstr.match(/(\d+)/);
