【问题描述】：
我正在编写日历并从数据库中提取事件信息。然后，我正在做一些处理（服务器端）以尝试使冲突的“事件”DIV 在日历上合理地重叠。我将数据传回浏览器，jQuery 将“事件”DIV 定位在其中。
因为它们重叠，我想我会让 jQuery 在鼠标悬停时将每个 DIV 弹出到前面（通过更改其 CSS z-index 属性），然后在鼠标移出时将其弹出。
这涉及我第一次使用 jQuery 数据绑定，它工作正常，但有一个问题：当我将鼠标悬停在我的一个“事件”DIV 中的（简单文本）内容上时，jQuery 将其视为鼠标脱离 DIV 本身。
我制作了另一个更简单的页面来测试 jQuery 的行为，在该页面中，鼠标悬停的行为与我预期的一样。
任何关于解决方法、我的代码问题或错误的想法将不胜感激 - 谢谢！
这是页面的代码：
