I have made it dynamic and gave unique ids to mark but same class, and using the ids I have determined its content. Now you can have any number of mark and content combinations and the hide and show will work
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
$(function () {
$(".mark").bind("mouseover", function () {
var index = $(this).attr("id").replace("mark", "");
$(".icontent" + index).show();
});
$(".mark").bind("mouseout", function () {
var index = $(this).attr("id").replace("mark", "");
$(".icontent" + index).hide();
});
});
</script>
<table border="1">
<tr>
<td align="left" valign="top">
<a href="#" class="mark" id="mark1">hover anchor 1</a>
</td>
<td align="left" valign="top">
<a href="#" class="mark" id="mark2">hover anchor 2</a>
</td>
</tr>
<tr>
<td align="left" valign="top" height="50">
<div class="icontent1" style="display: none">
lorem ipsum dolor sit amet......
</div>
</td>
<td align="left" valign="top" height="50">
<div class="icontent2" style="display: none">
lorem ipsum dolor sit amet......
</div>
</td>
</tr>
