JQuery loop through <link> and <script>

I am trying 开发者_如何学Pythonto loop through the elements link and script tag

$("script").each(function () {
 alert("Test");
});

The code works for img tag but does work for the above 2?

Try this:

$("script, link").each(function () {
   alert($(this).attr('type')); //:)
});
