getdivs.php
<div class="same" id="childcontainer1">  content here 
</div>
<div class="same" id="childcontainer2"> content here 
</div>
When I scroll down the window, I am getting the alerts of all the div's with (.same) class irrespective of the div I am viewing on the window. I want the ID's respective to the DIV'S shown on page on scrolling.
