Question

Relative newcomer to Javascript and a bit stuck with the following so would greatly appreciate some help…

I have a string made up of a list of categories and keywords which might appear like:

Category A:Keyword A, Category B:, Category C: Keyword B

The problem is displaying a category when there is no keyword – how can I do a Find and Replace to swap instances of :, with just ,?

I already use the following to insert a space after the comma:

cats = cats.replace(/,/g,", ");

but copying and modifying with the extra colon seems to break it…

Answer 1

Use:

cats = cats.replace(/:\s*,/g,", ");
