模块化JS:3个部分(复选框和无线电)的全局功能&Sholud 我在代码中应用"rendering"?



这是我的网络应用程序上的一个部分,用户可以在其中"订阅"在 3 个不同时间发送的报告:每周、每月、每季度。(可以从三个选项中的每一个中选择 1 个)。

我正在努力为此规划最佳解决方案,同时又在代码模式方面苦苦挣扎。

应该发生什么:

  • 加载页面时,我必须传递一个 PHP var,它将设置用户报告的当前状态(变量report在我的代码乞求 [{每周},{每月},{季度}]) 0,1,2,3 将是指标。例如:如果用户过去设置了他想要每月 6 个月的报告 - 他将看到选中"每月"复选框 - 并在单选按钮中选中"6 个月",变量将设置为[0,2,0]

  • 选中复选框时 - 启用 3(或 1)个单选按钮进行选择。

  • 取消选中复选框时 - 单选按钮被禁用,所有复选都将被删除。

  • "保存计划"按钮会将数据发送到PHP。

我的问题是:

  1. 如何以模块化方式构建代码,防止意大利面条代码?

  2. 解决问题 1 后 - 我应该应用"渲染"函数吗?(灵感来自此视频教程)

只是提到:

  • 这是一个JSFIDDLE,我的代码较少,意大利面条较少。 - 包括当前正在工作的内容。

  • 我正在练习模块化的JS代码,所以我很乐意获得参考我的代码的一般提示(推荐的链接,视频和教程等)。

  • 我正在使用jQuery 1.3.2,它不包括当前库的所有功能。(如parentson.('click', func..)

每当通过复选框或无线电BTNS进行任何更改时,都会使用渲染:
