Question

<div id="side">
    <h2 class="1">1</h2>
    <h2 class="2">2</h2>
    <ul>
        <li><a class="3"href="">3</a></li>
        <li><a class="4" href="">4</a></li>
    </ul>
</div>

What would the code be so when I hover over an <a> it will display the <h2>? So .3 would display .1?

This is what I’ve tried so far:

<script type="text/javascript"> 
    $(document).ready(function() { 
        $("#side a").hover( 
            function() { 
                $(this).children('.h2').show(); 
            }, 
            function() { 
                $(this).children('h2').hide(); 
            } 
        ); 
    }); 
</script>

This is an example for your test case, you should improve it for your live app.

        } else if($(this).hasClass("4")) {
