如果最小元素为null，则mvc跳过最大元素

Question

在MVC5 c＃实体框架项目上工作，在该项目中，用户正在输入一系列40个“最小值/最大值”。如果“最小”字段未填充或为空，则用户希望TAB跳过“最大”文件，然后转到“下一个最小”元素。这是我们正在转换为MVC / Entity Framework的当前应用程序中的行为，并且如果可能的话，希望复制该行为。

该代码示例每行的Min / Max字段具有3列。制表符顺序位于该列下方，并使用EditorFor语句上的tabindex来使制表符顺序起作用。

如果可能的话，我们只希望它跳过“最大”文件并转到下一个“最小”字段。感谢您的帮助或指导。
