JavaScript remove leading and trailing spaces

Question

Here is a test:

console.log(" Golden Katana of the Unflinching Dawn                                    ".replace(/\s+/g,""))

I want to remove the extra spaces at the end of the string but it removes every space in the string, so how could I remove just the extra spaces at the end and just keep Golden Katana of the Unflinching Dawn?

You can use str.trim() for this case. It removes the leading and trailing whitespace from a string. The regular expression str.replace(/^\s+|\s+$/g,'') will alternatively do the same thing.

I would just like to add that there are compatibility issues with IE8 browsers and below with using str.trim(). – calcazar Sep 09 '14 at 14:12

Good thing no one supports IE8 :D – Sebastian Patten Oct 21 '15 at 04:02

try doing

trimmedstr = str.replace(/\s+$/, '');

or maybe

.replace(/ +$/, "");
