jQuery Realizes Scroll Bar Position

jQuery enables scroll bars to scroll to child element positions (easy positioning)

The key code is as follows:

<div class="of-y" id="nurse" >
 　　 <table class="high width" id="nurse-plan">
<tr id="tr-one"></tr>
<tr id="tr-two"></tr>
<tr id="tr-three"></tr>
<tr id="tr-four"></tr>
</table>
</div>

jQuery:

$("#nurse").scrollTop($("#nurse").scrollTop() + $('#tr-three').offset().top - $("#nurse").offset().top); -- Ordinary 
$("#nurse").animate({ scrollTop: $("#nurse").scrollTop() + $('#tr-three').offset().top - $("#nurse").offset().top }, 1000); -- Have animated effect
