Trim whitespaces from both ends of a string, using Javascript

The code below uses the two functions used here and here. Read the tutorials mentioned previously before using the function below:

// Removes leading and ending whitespaces
// The string to be processed as an argument (value) to the function below
function trim( value )
return LeftTrim(RightTrim(value));

If you have JQuery enabled in your code, then you can also use Jquery's trim() function to trim whitespaces from both ends of a string.

var trimmed_str = $.trim( str_with_whitespaces );

Did this tutorial help a little? How about buy me a cup of coffee?
