Try this:

//remove leading spaces
content = content.replace(/^\s+/g,'');
//remove trailing spaces
content = content.replace(/\s+$/g,'');
//remove whitespaces in the middle
content = content.replace(/\s+/g,' ');

This should work to remove leading and trailing spaces, and reduce two or more spaces to a single space:

str.replace(/^\s+|\s+$/, '').replace('/\s\s+/', ' ')

You can use jQuery trim method.This function remove all new lines and all spaces leading or trailing from input string.

var str = '          it is a test string                ';

alert($.trim(str));
