replace empty space with dash only if trailing string

I'm using regEx and replace method to replace an empty space with a dash but I only want this to happen if there is a following character. For example if the input field looked like this then replace empty space between temp and string with dash

input = "temp string";

if it looked like this then it would just remove the empty space 

input = "temp  ";

here is my regEx replace right now. But not sure how to check if there are trailing characters.

input.value.replace(/\s+/g, '-');

/\s+$/ only finds trailing spaces, so add .replace(/\s+$/, '') after .value

This should do the trick: the first replace takes care of the trailing spaces (if there's at least one) the second one performs your original replacement

str.replace(/\s+$/g,'').replace(/\s+/g, '-');
