Question

I am attempting to scroll the window to a location on my page based on a user’s selection. I am getting some strange results. Can anyone suggest a good/better way to go about this?

Here is what I’m working with:

 var rel = $(this).attr('rel');
 var citation = rel.split("-")[0];
 window.scrollTo(0, $('[name = ' + citation + ' ]').offset().top);
 alert($('[name = ' + citation + ' ]').offset().top);

The last alert gives me a number that seems wrong and the scrolling is not working. The following code is executed when the user clicks on a link from within the document. I am capturing that element’s rel attribute value and (after a little string manipulation) using it to find the position of the corresponding anchor. The destination element’s name attribute should match the rel attribute of the clicked link. See what I mean?

Thanks!

I was able to get around this by not using offset() but by rather using jQuery’s position() function.

I am just getting the returned object’s “top” property. I have to use the element’s text as an index value because these elements did not have unique IDs.

var citationIndex = parseInt($(this).text() - 1);
var elementOffset = $('.HwCitationsContent li:eq(' + citationIndex + ')').position().top;
