im pretty new to jQuery and usually just doing PHP/HTML/CSS things.

I´ve googled and tried this many many hours in the last 2 days but i cant get it working. 

What i want to do: SmoothScrolling on same-page-links (working) and SmoothScrolling on new-page-links ("half-working"). 

My Code for same-page-links:

1. $(document).ready(function() {
2.     $('a[href*=#]').click(function() {
3.     if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'')
4.         &&location.hostname == this.hostname) {
5.             var $target = $(this.hash);
6.             $target = $target.length && $target || $('[name=' + this.hash.slice(1) +']');
7.             if ($target.length) {                              
8.                 var targetOffset = $target.offset().top;
9.                 alert(targetOffset);
10.                 $('html,body').animate({scrollTop: targetOffset}, 1000);
11.                 return false;
12.             }
13.         }
14.     });
15. });

To be honest I still dont know what line 6 exactly does... 

My code for new-page-links:

1. $=jQuery;
2. /*
3. if (window.location.hash) scroll(0, 0);
4. setTimeout(function() {
5.   scroll(0, 0);
6. }, 1);
7. */          
8. $(document).ready(function() {
9.   if (window.location.hash) {
10.   alert($(window.location.hash).offset().top);
11.     $('html, body').delay(500).animate({
12.       scrollTop: $(window.location.hash).offset().top
13.     }, 1000);
14.   }
15. });

Im alerting the offsets for both methods and getting different values. 

Example (same element): 2154.1875 pixels from top (opening link in new tab) and 2773.1875 pixels from top (clicking on same-page-link).

If I open the page in a new tab it always scrolls to the bottom of the element and Im not able to get why after these 2 days. I´ve tested it with different elements -> the difference between those 2 methods are changing. Sometimes its about 600px difference, sometimes 400px but its NOT nearly the height of the elements beeing scrolled to.

I dont get it. Could someone point me in the right direction please?
