我的下拉菜单上的点击事件没有触发。我没有看到警报，并且当我在 Firebug 中添加断点时，它没有到达断点。如果我在这些事件上设置断点，它确实会到达单击和双击事件。
具体来说，当我:
- 双击编辑一行
- 选择客户下拉列表并选择其他内容
- 移至另一行
然后是行
alert("I changed");
不运行。
我想知道这是否是因为当我移动到另一行时，该值会被恢复(即使我已经注释掉了 restoreRow 方法)
当我的下拉值发生变化时，我是否使用正确的事件来捕获(无需更改焦点)。

最佳答案
此外，不清楚为什么您在 ondblClickRow 内同时使用 inlineNav 和手动调用 editRow ？如果您选择行，然后单击导航器中的按钮，则 dataUrl 将不会调整。
您所描述的主要问题的原因是dataEvents的错误使用。在 editoptions 的文档中您会发现 dataEvents 是 editoptions 的属性，例如 dataUrl 。目前，您将 dataEvents 放置在 colModel 中的错误位置。
我建议您另外阅读the answer其中描述了如何使用 dataUrl 哪些参数取决于当前选定的行。此外，我建议您验证是否在 dataUrl 的响应中设置了 Cache-Control (请参阅 the answer )。或者，您可以使用描述的另一个选项 here .
