将div类传递给javascript函数

Question

Is it possible to pass the class of a div into a javascript function? I am using square space so I cannot add an id to the div, but I can get it to work with div's that do have id's. Also, I already have loaded the jquery.

This is what I am thinking so far, thanks in advance!

<script type="text/javascript">
function unhideme(arg) {
    $(arg).slideDown()
}

function clickme(arg1, arg2) {
    unhideme(arg1);
    unhideme(arg2);
    //other stuff
}
</script>
<style type="text/css">
#myid{
display:none
}
.klass{
display:none
}
</style>

<form><input type="submit" onclick="clickme('#myid','.klass')">
<div id="myid"></div>
<div class="klass"></div>
</form>
