jQuery external link anchor animate

Could not find a correct answer. I'd like to open the page then animate scrolled to the ID I called.

here is my code.

JQuery

   $(window).bind("load", function () {
              var urlHash = window.location.href.split("#")[1];
                $('html,body').animate({ scrollTop: $('a[href="#' + urlHash + '"]').offset().top}, 1000);
    });

Html

<div class="space"></div>
<div id="anchor">This is anchor</div>

css

.space{height:800px;}
#anchor{font-size:25px;height:800px;}

then jQuery is not working, so I pasted the following code to console

 $('html,body').animate({ scrollTop: $('a[href="#' + anchor+ '"]').offset().top}, 1000);

The error says

TypeError: Cannot read property 'top' of undefined

How could I solve this error? thanks

This code works: http://jsfiddle.net/4mjmw/4/

Demo: http://jsfiddle.net/4mjmw/4/show/#abc

I added an href to the anchor and moved the script to HTML.

$(window).bind("load", function () {
          var urlHash = window.location.href.split("#")[1];
            $('html,body').animate({ scrollTop: $('a[href="#' + urlHash + '"]').offset().top}, 1000);
      });
