Can I get the html.HiddenFor / Html.Hidden create an id or should I just create it manually?

asp.net-mvc

提问by Omu

I do this:

我这样做:

<%=Html.HiddenFor(o => o[i].HobbyId) %>

and it creates a hidden input but without id(just name, I need id).

它创建了一个隐藏的输入,但没有id(只是name,我需要id)。

Can I make it create an idalso ?

我可以让它也创建一个id吗?

atm I do it like this:

atm 我这样做:

<%=Html.HiddenFor(o => o[i].HobbyId, new Dictionary<string, object>{{"id", " _ "+i+"__HobbyId"}}) %>

A cleaner way to do it is

一个更干净的方法是

<%=Html.HiddenFor(o => o[i].HobbyId, new {id = " _ "+i+"__HobbyId"}) %>

but aside from that your existing method is ok. If you really want a simple syntax you can create an extension method that calls HiddenFor, but that hardly seems worth it.

但除此之外,您现有的方法还可以。如果你真的想要一个简单的语法,你可以创建一个调用 HiddenFor 的扩展方法,但这似乎不太值得。

I tend to do something such as:

我倾向于做一些事情,例如:

@Html.Hidden(
    string.Format("{0}ObjectId", Model.BindingPrefix), 
    Model.ObjectId
)

Which produces this:

产生这个:

<input id="customerModel_ObjectId" name="customerModel.ObjectId" type="hidden" value="3a44d3eb-58ec-4229-9fe0-e420d9855bb7">

The id and name convention is consistent and produces stable id and name values that do not change. This works perfectly for me.

id 和 name 约定是一致的,并产生稳定的 id 和 name 值,不会改变。这对我来说非常有效。

So to convert your example to my format:

因此,要将您的示例转换为我的格式:

@Html.Hidden(
    string.Format(" _ {0}__{1}", i, HobbyId), 
    HobbyId,
)

...that should get you what you want as well. Hopefully, I didn't inject any syntax errors while typing this out. :)

......这也应该让你得到你想要的。希望我在输入时没有注入任何语法错误。:)
