Javascript Split Space Delimited String and Trim Extra Commas and Spaces

Question

I need to split a keyword string and turn it into a comma delimited string. However, I need to get rid of extra spaces and any commas that the user has already input.

Answer 1

If you just want to split, trim and join keeping the whitespaces, you can do this with lodash:

// The string to fix
var stringToFix = "The Wizard of Oz,Casablanca,The Green Mile";

// split, trim and join back without removing all the whitespaces between
var fixedString = _.map(stringToFix.split(','), _.trim).join(' == ');

// output: "The Wizard of Oz == Casablanca == The Green Mile"
console.log(fixedString);
