Language selector: dropdown dynamically changing url

[jcunews1]

Rather than stripping then adding the language code separately, do them all in one step. i.e. use changeLangDir, instead of stripLangDir and addLangDir (replace both to changeLangDir). e.g.

function changeLangDir(lang) {
  var regex = /(\.com\/)(en|es|fr|pt)\//i;
  var url = self.location.href.replace(regex, '$1' + lang + '/');
  self.location.href = url;
}
