[Sugarcube 2] - Using an external editor

As I've mentioned before, I am very green as far as JavaScript is concerned, so the code I'm using is something I found on StackOverflow. Essentially, I'd like to be able to edit my passages in Notepad++ and then link to those files within the passages. Is this possible how I'm attempting it (or in any other way)?

<<script>>
$(document).ready(function() { 
    $('#pageContent').load('test.html');
}
<</script>>
<</silently>>
<div id="pageContent"></div>
