Answer 1

Try doing GET as your request type. So your new code would read,

$.ajax({
    type: "GET",
    url: "jquery.jsPlumb-1.3.16-all-min.js",
    dataType: "script"
    });

Also make sure that jquery.jsPlumb-1.3.16-all-min.js exists in the same directory as index.htm . This still won't load it directly into the page, but would be able to access the text and then manipulate it however you want.

Answer 2

In my opionion, AJax shouldn't be used to download resource files, but rather to communicate with the server from the client. Too many implications in the former.

What is your expected outcome with loading the js file?

If you're really intending on doing this (and I wouldn't suggest it), use jQuery.getScript():
