title: Passing multiple parameters to a function
body: <p>How can I pass two parameters in a function?</p>
  
  <p>what i've tried:</p>
  
  <pre><code>function loadweek(loader,button){
    var button_2 = button + "_2";
    alert(button_2);
    alert(button);
    alert(loader);
  }
  
  $("#load_week").click(function () {
          loadweek("#load_weekme","#load_week");
  });
  </code></pre>
  
  <p><code>alert(loader);</code> is working, but the button is "undefined"</p>
