var title = ListItem.get_item("Title");
alert("Updated List Item: \n Id: " + id + " \n Title: " + title);
}

ListItem = list.getItemById(ctx.CurrentItem.DocId);
clientContext.load(ListItem, "Id", "Title");

}

I got the same exception after upgrading jQuery located in top level site. The reason was reference to old jQuery library in subsitemaster page.
升级位于顶级站点的 jQuery 后，我遇到了同样的异常。原因是在子站点母版页中引用了旧的 jQuery 库。
