I need some javascript to remove only leading and trailing spaces on a string, but not spaces in between any other characters

Question

How do I trim a string in JavaScript?

So....

"   steve   monkey   "

would become "steve monkey"

and...

"   cheese charlie face   "

would become "chesse charlie face"

so basically take out all space characters that occur before the first non-space character, and also remove all space characters after the last non-space character, but don't remove any spaces in between. thanks!!!

right now i am just removing all spaces like below, but i learned we need to keep spaces in the middle... :(

$newPassword.val().split(" ").join("")

Use trim():

var testString = "                 hello                   wold        ";
alert("The text:"+testString.trim()+"End here");

EDIT: As noted in the comments and in the other answer, this doesn't work in IE < 9. The jquery option does work on all browsers:

$.trim(testString);

Thanks to Joseph and mplungjan for clearing that!

JQuery (Seems you use that):

$.trim(str)

Works in all browsers

Please note that

Str.trim()

Does not work in IE8
