JSONP - Explain jQuery.ajax () pitfalls of static "jsonpCallback" (jQuery random callback names)

I maintain my JSONP JavaScript file on a static file server - GitHub Pages.

This means that I cannot dynamically set the name of the JSONP callback function on the server ...

Dynamic Example - PHP

header('Content-Type: text/javascript; charset=utf8');
$data = '{ "foo":"bar" }'; // json string
echo $_GET['callback'] .'('.$data.');'; // function name set via ?callback=xyz

jQuery.ajax () has a parameter jsonpCallbackto determine the name of the static callback function. Therefore, I can server a javascript file, for example. test-jsonp.jswith the following contents:

Static Example - JavaScript File

jsonpCallbackABC({ "foo":"bar" });

However, jQuery documentation recommends static .
