How do I trim a string in javascript?

I need to remove only the last and the first spaces from a generic string.

Example:

var str = " hello world "; // become "hello world"
var str = "ehi, do you come from ? "; // become "ehi, do you come from ?"
var str = "I am from Cina"; // remain "I am from Cina"

How can I do that ?

Answer 1

The trim from jQuery is what you are looking for.

$.trim(' string with spaces at the ends ');

Or plain javascript:

' string with spaces at the ends '.trim()
