jQuery Replace part of string using a variable

Question

This one seems simple, but I have no idea why it's not working. I would like to replace part of a string in a variable.

Say, I have this code:

var url = "At vero eos et accusam et justo duo dolores et ea rebum.";
url.replace('At vero eos et accusam et ', '');

Why doesn't it work? This one works:

var url = "At vero eos et accusam et justo duo dolores et ea rebum.".replace('At vero eos et accusam et ', ''):

-- but I'm using the variable elsewhere, so I would like to keep the replace out of the variable definition.

Fiddle here.

Answer 1

You need to save the replaced string

  var url = "At vero eos et accusam et justo duo dolores et ea rebum.";
  url = url.replace('At vero eos et accusam et ', '');
//^^^^^this
