JQuery :: Adding Click() Event To <a>

I have a situation on my website similar to this:

<ul id="menu1" class="menu">
<li>
<a href='javascript:myFunction(0)'>Hello</a>
</li>
</ul>

This makes a link that calls myFunction(0) when I click it. Now I want to add a popup whenever the user clicks the link (but I can't add it to myFunction for some reason), so I add an event listener to this <a> in the $(document).ready() function:

$('ul.menu li a').click(
function() {
alert("hi");
});

Now the the popup does appear, but it doesn't execute myFunction(0) anymore.

So finally my question: is there a way to pass my <a>'s href to this click-function and makes it execute? Or is there a better way?
