Question

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, '-');

input = $.trim(input.replace(/\b \b/g, '-'));
