跟踪变化看起来确实可行。另一种选择可能是使用空闲事件来监控故事的变化。基本上就是Josh刚才建议的。

# targetengine "storiesChanges"

main();
function main()
{
	var db = {};

	var myIdleTask = app.idleTasks.item("checkStories");
	if ( !myIdleTask.isValid ) {
		myIdleTask = app.idleTasks.add({name:"checkStories", sleep:100});
		myIdleTask.addEventListener(IdleEvent.ON_IDLE,onIdleEventHandler, false);
	}

	function onIdleEventHandler(myIdleEvent)
	{
		var doc = app.properties.activeDocument;
		if ( !doc ) {
			db = {}
			return;
		}

		var sts = doc.stories, st, id;
		var n = sts.length;

		while ( n-- ) {
			st = sts[n];
			id = st.id;

			if ( !db[id] ) {
				$.writeln ("Storing "+id );
				db[id] = st.contents;
			}
			else if ( db[id]!=st.contents ) {
				$.writeln ( "Some changes were made on story "+id+" at "+(new Date()) );
				db[id] = st.contents;
			}
			else {
				$.writeln ( "No changes were made for story "+id );
			}
		}
	}
}
