I don't have a copy of IE/win handy to test, but this works the same in 
Mozilla browsers, and in Safari.

function getRef2Myself() {
	var aScripts = document.getElementsByTagName("script");
	
	for ( var i = 0; i < aScripts.length; i++ ) {
		
		alert( i + ":" +aScripts[i].getAttribute("src"));
		// returns text of the attribute
		alert( i + ":" +aScripts[i].src);
		// returns full url that the text resolves to
	}
}
