replace captured spaces an unknown number of times with regex

If I have a regex that matches the city/state formats The City, ST pattern with the consideration that some towns have multiple words in their names, how can I reduce them to this format?

new_town_city_st

My expression: /(\w+(\s))*(\w+)(,\s)(\w{2})/

How can I replace where I have captures (spaces) with underscores when I don't know how many words each town name will be?

Just replace all repeated non-word characters (\W) with an underscore as follows:

var locationInput = 'New Town City, ST';

var underscoreLocation = function(location) {
    return location.replace(/\W+/ig, '_').toLowerCase();
};

var locationOutput = underscoreLocation(locationInput);
// => new_town_city_st

myString=myString.replace(/,\s*|\s+/g,'_');

edited to throw comma into the mix

edit: your post didn't explicitly say it but if you wanted it to be lower cased:

myString=myString.replace(/,\s*|\s+/g,'_').toLowerCase();
