Trim to remove white space

Question

jQuery trim not working. I wrote the following command to remove white space. Whats wrong in it?

var str = $('input').val();

str = jquery.trim(str);
console.log(str);

Answer 1

The trim() method removes whitespace from both ends of a string and returns a new string, without modifying the original string. Whitespace in this context is all the whitespace characters (space, tab, no-break space, etc.) and all the line terminator characters (LF, CR, etc.)
