使用EditorFor / TextBoxFor /文本框佣工名以破折号自定义属性 [英] Custom attribute with dash in name using EditorFor/TextBoxFor/TextBox helpers

问题描述

我用淘汰赛JS来在我看来属性绑定到我的视图模型。淘汰赛-JS使用一种称为数据绑定，你必须追加到要在其中要绑定到查看模型对象控件的自定义属性。

I am using Knockout-JS to bind properties in my view to my view model. Knockout-JS uses a custom attribute called 'data-bind' that you have to append to controls in which you want to be bound to view model objects.

例如：

<input type='text' name='first-name' data-bind='value: firstName'/>

请注意数据绑定属性。

Notice the 'data-bind' attribute.

在我看来渲染，我有麻烦渲染有这个属性的文本框。我知道了Html.EditorFor，Html.TextBoxFor和Html.TextBox助手都以匿名的对象，您可以用它来指定自定义属性。这个实现的唯一问题是C＃不允许破折号作为变量名，所以这不会编译：
    @ Html.EditorFor（M => m.FirstName，新的{数据绑定=值：名字}）;

In my view rendering, I am having trouble rendering a textbox that has this attribute. I am aware the Html.EditorFor, Html.TextBoxFor, and Html.TextBox helpers all take an anonymous object that you can use to specify custom attributes. The only problem with this implementation is C# doesn't allow dashes as variable names, so this won't compile: @Html.EditorFor(m => m.FirstName, new { data-bind = "value: firstName" });

我能想到的唯一事情是这样的（在视图模型）：

The only thing I can think of is this (in view-model):

public class DataBindingInput
{
     public string Value { get; set; }
     public string DataBindingAttributes { get; set }
}

public class MyViewModel
{
    ...
    public DataBindingValue firstName { get; set; }
    ....
}

和一个名为DataBindingInput.cshtml视图模板：

And a view template called "DataBindingInput.cshtml":

@model DataBindingInput
<input type='text' data-binding='@Model.DataBindingAttributes' value='@Model.Value'>

这个唯一的麻烦是我失去的输入名称的自动生成，这样就不会在后回工作，因为该模型粘合剂具有不知道如何绑定。

The only trouble with this is I lose the automatic generation of the input name so it won't work on a post-back because the model binder has no idea how to bind it.

我怎样才能使这项工作？

How can I make this work?

推荐答案

由于上述新月鱼，貌似你可以使用下划线和MVC 3将它们转换为破折号，因为下划线在允许使用HTML属性名。

Thanks to Crescent Fish above, looks like you can just use underscores and MVC 3 will convert them to dashes since underscores aren't allowed in HTML attribute names.
