Johannes, you have to execute the examples after the DOM is ready.
Otherwise a query like $('a') returns 0 elements (because at that time
there no elements).
<script type="text/javascript">
$(document).ready(function() {
$("a").click(function(){
alert("Thanks for visiting!");
});
</script>
$(document).ready() attaches a function to be executed when the DOM is
ready (which is earlier than the load event).
You will often see a shorter form for that:
$(function() {
// do something with DOM
});
