Answer 1

The load event for script elements was introduced in HTML5, prior to that it was only available for frameset and body elements (though most browsers also implemented it for img elements too). So if you want to support earlier browsers you'll need to be creative.

One solution is to put a function call at the top of the script to say that the script has been loaded, as the browser should not execute any code in the script until it's loaded in its entirety.

Another is to insert a second script with the "I'm loaded" function or flag immediately after the first in the presumption that the second will not be executed until the first has been loaded and executed.
