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) 
{
            


        

Answer 1

You can simply use the indexOf method on the input string:

function hasWhiteSpace(s) {
  return s.indexOf(' ') >= 0;
}

Or you can use the test method, on a simple RegEx:

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

This will also check for other white space characters like Tab.
