Question

我不明白这个错误！我有一个JavaScript函数，我在运行时为字符串赋值，如下所示：

<script type="text/javascript">
    RefreshDashButtons() {
...

    Line 532:         dash10FTEs = "@(branch.FTEs.ToString())";
    Line 533:         dash10TurnoversOpen = @(branch.Turnovers.ToString()) + " | " + @(branch.OpenPositions.ToString());
    Line 534:         dash10Style = "@(branch.MTDDash10StyleOV)";
    Line 535:     }
    Line 536: }
...

    }
</script>

当执行到达第534行时，我得到DivideByZeroException。这是堆栈跟踪：

System.DivideByZeroException was unhandled by user code
  HResult=-2147352558
  Message=Attempted to divide by zero.

  StackTrace:

       at System.Web.Mvc.ControllerActionInvoker.InvokeActionResultFilter(IResultFilter filter, ResultExecutingContext preContext, Func`1 continuation)
  InnerException: null

这显然是某种内部.NET错误，这不是我主要担心的问题（尽管很奇怪）。我想做的是优雅地处理错误，甚至只是吸收错误。任何人都可以建议如何使用JavaScript内部的.NET代码？我试过评论这条线;但是然后错误发生在前一行，这也只是分配一个字符串。

我已经完成了代码，一切都很好，直到我点击这一行。在运行时，branch.MTDDash10StyleOV =＆＃34; bbtext-normal＆＃34;。也就是说，从第533行开始。

希望这有帮助吗？

如何在MVC视图中处理@（）标记内的错误;还有为什么DivideByZero错误？
