regular expression for is empty space
I'm suresomeone of you know how to do this easily, I am trying to validate my inputs that only allows numbers, characters and/or an empty space which mean nothing in a string "", so I have /^[0-9a-zA-Z]+$/ only missing that empty space in there. Seems I can't find the express for it, so I tried to create a variabel var emptyStr = "" and put it in there but don't really know how to write the correct syntax.

Use * rather than +. * is 0 or more times. + is 1 or more times.
/^[0-9a-zA-Z]*$/
