获取禁用降值倒在asp.net mvc的 [英] Get value of disabled drop down in asp.net mvc

问题描述

我有一个ASP.NET MVC应用程序。我有我的网页（HTML SELECT）多重下拉列表中，我必须禁用它们，用户通过人去上选择其中之一。当用户帖子回控制器，我得到null作为功能（操作方法）paramters。我搜索，发现HTML不会在表单数据发送残疾人领域的价值。与只读更换disabled属性是行不通的，因为它会使下拉工作。

I have an ASP.NET MVC application. I am having multiple drop-down list in my page (HTML SELECT), I have to disable them, as user goes on selected them one by one. When the user posts it back to the controller, I am getting null as the function (action method) paramters. I searched and found that HTML does not send value of disabled fields in the form data. Replacing disabled attribute with readonly would not work as it would render drop-down working.

我是动态生成的下拉列表中的用户继续使用JavaScript。所以没有一个单一的下拉列表中，但多达用户希望。

I am generating the dropdowns dynamically using javascript as user goes on. So there isn't a single dropdown, but as many as user wants.

有人可以告诉我，我应该怎么获取值？

Can someone please tell me how should I get the values ?

推荐答案

一种可能性是使下拉列表禁用=禁用，包括一个隐藏字段与相同的名称和值，这将使这个值发送到服务器

One possibility is to make the dropdown list disabled="disabled" and include a hidden field with the same name and value which will allow to send this value to the server:

@Html.DropDownListFor(x => x.FooId, Model.Foos, new { disabled = "disabled" })
@Html.HiddenFor(x => x.FooId)

如果你要动态禁用了JavaScript，然后只是简单地禁用后的下拉菜单，隐藏字段的当前选择的值赋给，下拉

If you have to disabled the dropdown dynamically with javascript then simply assign the currently selected value of the dropdown to the hidden field just after disabling it.
