Scroll to a specific row of the table using Jquery

Following example show  how to scroll to a specific row of the table in a div with overflow set to true. The example shown here has two tables Employees and Departments.On Clicking an employee the second table should scroll to the corresponding Depart row and highlight that row.

This example can be quickly tested on jsfiddle: http://jsfiddle.net/sanjayingole/z9gw3rb7/2/embedded/result/

<head>
<style>
body { background-color: #EFFFEF; color: #000000; }

.tableDiv {
    border : solid 1px #000000;color: #0000FF; margin : 10px; background : #FFEFFF; height : 100px;  float : left; overflow : auto; 
}
.empDiv {
    width : 70%;
}
.empLink {
    color : #0000FF;
}
.column{
    padding-left : 10px;
}
.even {
    background : #EFDFEF;
}

</style>

 <script>
function scrollIntoView(element, container) {
  var containerTop = $(container).scrollTop();
  var containerBottom = containerTop + $(container).height();
  var elemTop = element.offsetTop;
  var elemBottom = elemTop + $(element).height();
  $('tr[rel="deprow"]').removeAttr("style")
  $(element).attr("style", "background : #AFFFA0");
  if (elemTop < containerTop) {
    $(container).scrollTop(elemTop);
  } else if (elemBottom > containerBottom) {
    $(container).scrollTop(elemBottom - $(container).height());
  }
}

$(document).ready(function() {
    $('a[rel="testclick"]').click(function(){
        $('a[rel="testclick"]')
        var containerDiv = document.getElementById('departDiv');
        //var itsme = $( $.attr(this, 'href'));//document.getElementById('itsme');
        var itsme =document.getElementById($.attr(this, 'href'));
        scrollIntoView(itsme, containerDiv);

        return false;
    });
});
</script>
