Question

I need to convert a string like this:

tag, tag2, longer tag, tag3

to:

tag, tag2, longer-tag, tag3

To make this short, I need to replace spaces not preceded by commas with hyphens, and I need to do this in Javascript.

Answer 1

I think this should work

var re = new RegExp("([^,\s])\s+" "g");
var result = tagString.replace(re, "$1-");
