我需要在多对多模式对话框中保留状态渐进增强 http://en.wikipedia.org/wiki/Progressive_enhancementASP.NET MVC 项目中的方式。
在我的代码中，当禁用 javascript 时，模式对话框将导航到另一个页面并返回，但是当启用 javascript 时，对话框将作为 jquery 模式对话框打开，就可以了。
我在用着this https://stackoverflow.com/questions/442704/how-do-you-handle-multiple-submit-buttons-in-asp-net-mvc-framework/7111222#7111222从单击视图中选择操作的方法。
下面的代码显示了一个母版页调用详细信息页，有视图和控制器。只有一个主控调用一个详细信息对话框，但我有另一个视图/控制器，其中一个主控可以调用许多不同的详细信息对话框，有时一个对话框可以像母版页一样运行并调用嵌套的另一个对话框。一切都必须在调用之间保持状态。
问题是它非常复杂，有很多代码来保持状态和管理对话框，我需要在各处重复相同的 JavaScript 和控制器代码，我希望有某种方法来简化它。
在视图方面，需要将脚本通用以移动到单独的 .js 文件并保持最少的 JavaScript 视图。
在控制器方面，我搜索了很多通用方法来实现它，例如过滤器或自定义活页夹，但找不到。
