寻求帮助...我正在使用 ASP MVC3 和 jQuery Mobile。我已经建立了一组级联下拉选择列表，当您第一次打开页面时可以正常工作。但是，提交表单后，它会返回到此页面，以便用户可以在需要时输入更多信息。问题是在您返回页面后级联下拉菜单不再起作用。

在 Firebug 中调试时，我在控制台中看不到任何错误。我必须进行 Control + F5 刷新才能让他们重新开始工作。如果我关闭 jQuery mobile ajaxEnabled 设置，那么它工作正常，所以这与 jQuery 移动框架和加载我认为的页面有关......

有人有想法么？

谢谢

编辑：以下是此页面的视图。基本上正在发生的是 $('#GasStation').change 事件似乎在用户被带回此页面后从未触发。如果我禁用 jQuery 移动 ajax 功能，它工作正常。
