推荐答案

您可以建立一个隐藏字段在窗体的状态（我假设的状态是你RegisterModel？一个属性），并在您的stateID.change功能已它赋予价值的隐藏字段为它在提交通过。

You could set up a hidden field in your form for the state (I assume state is a property on your RegisterModel?) and in your stateID.change function have it assigned the value to the hidden field for it to be passed on submit.

例如：

在表单隐藏字段可以设置与（内您的形式开始code）：

Hidden field in the form can be set up with (inside your begin form code):

@ Html.HiddenFor（型号=＆GT; model.StateID，新{ID = hiddenStateID}）

那么你的jQuery的将是（未经测试，这是更pseduo code给你的想法）：

Then your jQuery would be (untested, this is more pseduo code to give you the idea):

$(document).ready(function () 
 {  
        $("#stateID").change(function (){
             var state= $('#stateID :selected').text();
             getCities(state);
             $("#hiddenStateId").val(state);
        });
 });
