JQuery :: Pass The Dynamic Div Id To The Onclick Function?

I am trying to pass the dynamic div id to the jquery onclick function.

Here is the html code

HTML Code:
<div id = "show1" class="test">Click 1</div>
<div id = "show2" class="test">Click 2</div>

Code:
<script>
$(document).ready(function(){
$(".test").click(function(){
$("#show1").slideToggle("slow");
});
</script>

So it works for the first div not for the second one.There is something called "closest" id selector in jquery but not sure.
