JavaScript RegExp for spaces and numbers

Question

I have found two regex functions. One validates only numbers and the other only spaces.

function isNumber(value) {
    var numberRegex = /^\d+$/;
    return numberRegex.test(value);
}

function hasWhiteSpace(str) {
    return /\s/g.test(str);
}

I am looking for a function that returns true if a string contains numbers or spaces. Can you please help?
