Question

我一直在做一些简单的事情，但我无法找到解决方案。我有一张桌子：

第一列是文章代码，第二列是描述，其他列是文章所在的商店和它们的安装。每次我查看一个数量（数量）我都会向PHP脚本发出ajax请求。我甚至不会解释脚本会做什么，因为我只是强行给我一个默认值，只是为了调试。

当我将查看该单元格时，我将显示带有产品图像的工具提示（我强制图像也用于调试），并在图像下方显示文本（强制ajax响应）。我的问题是，有时它会显示带有强制图像的工具提示，但不显示强制的ajax响应。它给了我一个空洞的回应。

在开始时，一切正常，然后它开始在几个特定的细胞上做，然后我刷新，我开始在其他细胞。我无法理解这种行为（如果您想尝试，请将表添加为示例，并填充控制台日志以检查一切是否正常）。
