ile加载（来自jquery代码）确实需要5-10秒才能显示？是的，很遗憾，在线测试需要5-10秒：（…我不知道为什么…。可能是函数的执行导致了延迟？如果加载消息也有此延迟，您的错误可能在javascript代码中。这真的很奇怪..您可以发布更多的js代码或提供一个实时示例（由于安全问题，没有mysql查询）谢谢Fabian，这个想法很好，但不幸的是结果是一样的……加载Div的显示时间几乎相同：（我以为你想添加一条加载消息。也许我在这里搞错了：

是否有任何方式显示某种加载以让查看者理解

。很难说为什么加载速度慢，正如评论中已经提到的那样，远程数据库可能很慢，或者只有在这种情况下，你才面临此问题？你是否尝试过运行que正如@eggyal所说的那样，ry直接显示？带有消息“加载时请稍候”（来自jquery代码）的div确实需要5-10秒才能显示？是的，不幸的是，在线测试需要5-10秒：（…我不知道为什么…。可能是函数的执行导致了延迟？如果加载消息也有此延迟，您的错误可能在javascript代码中。这真的很奇怪..您可以发布更多的js代码或提供一个实时示例（由于安全问题，没有mysql查询）
