I am trying to make a JS script (utilizing Jquery) to make certain tablerows appear or disappear based upon whether a checkbox is checked or unchecked. I was experimenting with buttons to make these tablerows appear/disappear and was successful, but now I want to make it work for checkboxes. This is my first JS code I've tried to write, so please excuse the noob in me.

I did some checking, and apparently the cat function is not even called... hmm

$(document).ready(function(){
    
function cat(cat) {
        if (getElementById("#" + cat + "\"").checked) {
            $("[cat='" + cat + "']").addClass("show");
            $("[cat='" + cat + "']").removeClass("hide");
    } else {
            $("[cat='" + cat + "']").addClass("hide");
            $("[cat='" + cat + "']").removeClass("show");
            }
}


$("#Art").click(cat("Art"); alert("sometext"););


});

<form>
Categories:<br />
<input type="checkbox" id="Art" /> Art<br />
<input type="checkbox" id="Academic" /> Academic<br />
<input type="checkbox" id="Environment" /> Environment<br />
<input type="checkbox" id="Sports" /> Sports<br />
<br />
Schools:<br />
<input type="checkbox" id="5C" /> Five-College<br />
<input type="checkbox" id="CM" /> Claremont McKenna<br />
<input type="checkbox" id="CM" /> Harvey Mudd<br />
<input type="checkbox" id="PZ" /> Pitzer<br />
<input type="checkbox" id="PO" /> Pomona<br />
<input type="checkbox" id="SC" /> Scripps<br /><br />
</form>

Any help would be greatly appreciated! I have done a lot of Googleing to no avail.

Not sure if this is what you mean:

<script type="text/javascript">
<!--

$(document).ready(function() {

    $('.hideThis').hide();
    $('.checkBox').click(function() {
        $('.hideThis').toggle();
    });

});


//-->
</script>

<form action="" method="post">
    <label>Show me the hidden animals:</label> <input type="checkbox" name="something" class="checkBox" />
</form>

<table border="1" width="100%">
    <tr class="hideThis">
        <td>Dog</td>
        <td>Cat</td>
    </tr>
    <tr>
        <td>Birds</td>
        <td>Fish</td>
    </tr>
</table>

Exactly what I meant! Thank you so much! I played around with it for another 2 hours after that post with no luck. Thank you!
