JavaScript trim function Equivalent of PHP trim Function

This function returns a string with whitespace stripped/removed from the beginning and end of string . Without the second parameter, trim() will strip these characters:

* " " (ASCII 32 (0x20)), an ordinary space.
* "\t" (ASCII 9 (0x09)), a tab.
* "\n" (ASCII 10 (0x0A)), a new line (line feed).
* "\r" (ASCII 13 (0x0D)), a carriage return.
* "\0" (ASCII 0 (0x00)), the NUL-byte.
* "\x0B" (ASCII 11 (0x0B)), a vertical tab.

In PHP we can easily use trim($string) and all whitespace are stripped And in JavaScript we use this function to stripped the White spaces.

function trim(sValue)
{
return sValue.replace(/^\s+|\s+$/g, "");
}
