连接MVC Razor模型对象名称以在JavaScript中使用

我正在查看另一个开发人员的代码，我忍不住认为应该有更好的方法来清理代码。在过去的一天半里，我一直在寻找和尝试不同的方法。任何帮助都将不胜感激

我们有一个MVC4 Razor网站，我们正在为执行仪表盘开发。该网站正在运行，但性能不是它需要的。我已经开始做代码检查，发现业务逻辑代码都在视图中

我知道逻辑应该主要在模型和控制器中，但他拥有视图中的一切。由于这个项目的复杂性和我们必须提取的数据量，如果可能的话，我想开始通过小步骤重写来清理它

我想处理的第一件事是创建一个例程来处理下面的代码，以便将数百行代码减少到一个较小的数目。我计划根据页面上下拉列表的选定值设置分支编号

目前，他声明如下：

var b1 = Model.Branches.Where(b => b.BranchID.Equals(1)).First();
var b2 = Model.Branches.Where(b => b.BranchID.Equals(2)).First();
var b3 = Model.Branches.Where(b => b.BranchID.Equals(3)).First();
...
var branch = $("#BranchList").val();

并在开关中使用这些变量（如下所示）：
