Check if a string has white space

Question

I\'m trying to check if a string has white space. I found this function but it doesn\'t seem to be working:

function hasWhiteSpace(s) 
{

One simple approach you could take is to compare the length of the original string with that of the string to have whitespaces replaced with nothing. For example:

function hasWhiteSpaces(string) {
    if (string.length == string.replace(" ", "").length) {return false}
    return true
}
