[jQuery] anonymous function and code reusing

[jwc]

Hi guys,
apologize for posting again the same topic. I haven't found a solution
yet
for my simple problem.

I have a simple function that works when a link is clicked

$(document).ready(function(){
   $("#moon").click(function(){
        alert("do something");
   });
});
I need to reuse that function passing a parameter so I modified the
function
like that


$(document).ready(function(){
  $("#moon").click(myFunction("param"));
  $("#earth").click(myFunction("param2"));

  function myFunction(param){
    alert(param);
  }
});

I thought it should have worked but it doesn't. In fact, when the page
has
loaded even without clicking the first and second istructions are
executed:
 $("#moon").click(myFunction("param"));
 $("#earth").click(myFunction("param2"));

whereas with the following case

  $("#moon").click(function(){
        alert("do something");
   });
the function need to be activate by a click

any idea?
Thanks a lot
c
