I need to remove only the last and the first spaces from a generic string.
我只需要从通用字符串中删除最后一个和第一个空格。
Example:
例子：
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 ?
我怎样才能做到这一点 ？

The trim from jQueryis what you are looking for.
$.trim(' string with spaces at the ends ');
$.trim(' string with spaces at the ends ');
Or plain javascript:
或者普通的javascript：
' string with spaces at the ends '.trim()
' string with spaces at the ends '.trim()
