CommentChanged 事件会在批注发生变化的时候被触发（比如某些属性的值发生变化）。
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
initSpread(spread);
};
function initSpread(spread) {
var spreadNS = GC.Spread.Sheets;
var sheet = spread.getSheet(0);
var sheet = spread.getActiveSheet();
sheet.comments.add(1, 1, "new comment!");
sheet.setText(1,1,"Comment");
var commentEvent = document.getElementById("commentEvent");
sheet.bind(spreadNS.Events.CommentChanged, function(e, args) {
var text = commentEvent.value;
if (text !== "") {
text += '\n';
}
commentEvent.value = text + "CommentChanged: " + " " + args.propertyName;
});
// get comment and change some properties to fire event
var comment = sheet.comments.get(1, 1);
comment.text("Edit the comment, do resize, drag or other actions to fire the CommentChanged event.");
comment.backColor("white");
comment.foreColor("#82BC00");
comment.displayMode(spreadNS.Comments.DisplayMode.alwaysShown);
};
