推荐答案

MVC确实无关紧要，您可以使用javascript做到这一点.输入控件上有一个onkeyup事件，您可以使用它来检查输入的长度.我会编写一个方法，该方法带有一个文本框和要转到下一步的控件的名称，然后您可以编写代码来检查长度并将焦点设置为3时传递的id.

MVC is irrelevant really, you do this with javascript. There''s a onkeyup event on the input control, you can use that to check the length of input. I''d write a method that takes a textbox and the name of the control to go to next, then you can write code that checks the length and sets the focus to the id passed in when it is 3.
