模型绑定禁用了文本框 [英] Model Binding With Disabled Textbox

问题描述

我有我定义为

<%= Html.TextBox("Username", Model.Form.Username, 
        new { @class = "textbox", @disabled = "disabled" })%>

在我的行动

    [AcceptVerbs(HttpVerbs.Post)]
    [ValidateAntiForgeryToken]
    public ActionResult EditLogin(LoginForm post) {

        ...

        return View(model);
    }

post.Username将是空白，所有其他属性绑定正确的，但如果我改变@禁用=残疾人@只读=只读的用户名正确结合，一切工作。

post.Username will be blank, all other properties bind correctly, but if I change @disabled="disabled to @readonly="readonly" the username binds properly and everything works.

它看起来像模型绑定在残疾人领域的忽略值。难道自己解决的办法？我还需要该字段的值绑定到模型。我可以只读使用，但将preFER使用禁用所以它是明显可见的用户，他们不能编辑该字段的值。

It looks like model binding ignores values in disabled fields. Is their a way around this? I still need the field's value to bind to the model. I can use readonly but would prefer to use disabled so it is visually apparent to the user that they cannot edit the value of the field.

推荐答案

我相信一个表单字段被禁用不提交任何东西。如果你有一个表单，并以该形式禁用foo的领域，当你发布后不会对foo的字段的值。这是一个简单的HTML禁用场的性质，而不是一个MVC问题

I believe a form field that is disabled does not submit anything. If you have a form and disable the foo field in that form, when you post the post will not have the value for the foo field. This is simply the nature of disabling a field in HTML and is not a MVC issue.
