ASP.NET MVC 2点替换为下划线在元素名称 [英] ASP.NET MVC 2 Dots Replaced With Underscore In Element Name

问题描述

ASP.NET MVC 2点替换为下划线在元素名称（即使ASP.NET MVC将投入点在默认情况下，name属性！）

当您在ASP.NET MVC窗体上坚持一个元素，它通常执行以下操作：

 ＆LT;％= Html.TextBoxFor（型号=＆GT; model.Contact.FirstName）％GT;
 

变为

 ＆LT;输入类型=文本名称=Contact.FirstNameID =Contact_FirstName...
 

这是一切都很好。但是，如果你再要做到这一点：

 ＆LT;％= Html.DropDownList（
    CONTACT_TITLE
    新的SelectList（Model.Titles，键，值））％GT;
 

您实际上结束了

 ＆LT;选择ID =CONTACT_TITLENAME =CONTACT_TITLE＆GT; ...
 

请注意，你现在有一个下划线不能在名称属性点。

所以，我想我会在传递的名字，其中包括一个点，就像这样：

 ＆LT;％= Html.DropDownList（
    CONTACT_TITLE
    新的SelectList（Model.Titles，键，值），
    新{NAME =联系\\\\标题。}）％GT;
 

但它仍然呈现为：

 ＆LT;选择ID =CONTACT_TITLENAME =CONTACT_TITLE＆GT; ...
 

我真的（真的）希望这呈现为：

 ＆LT;选择ID =CONTACT_TITLENAME =Contact.Title＆GT; ...
 

在为了这个自动绑定回Model.Contact.Title - ？任何想法

重要更新

这是我最初的想法略有不同......它实际上看起来像什么我传递的name属性会被忽略......

 新{NAME =MYNAME}
 

仍然导致CONTACT_TITLE！

任何帮助AP preciated！

解决方案

 ＆LT;％= Html.DropDownList（
    Contact.Title
    新的SelectList（Model.Titles，键，值））％GT;
 

这会使：

 ＆LT;选择ID =CONTACT_TITLENAME =Contact.Title＆GT; ...
 

它只是因为它不是在XHTML有效的替换在id点。

ASP.NET MVC 2 Dots Replaced With Underscore In Element Name (even though ASP.NET MVC will put dots in by default in the name attribute!)

When you stick an element on a form in ASP.NET MVC, it usually does the following:

<%= Html.TextBoxFor(model => model.Contact.FirstName)%>

Becomes

<input type="text" name="Contact.FirstName" id="Contact_FirstName" ...

This is all well and good. However, if you then want to do this:

<%= Html.DropDownList(
    "Contact_Title",
    new SelectList(Model.Titles, "Key", "Value"))%>

You actually end up with

<select id="Contact_Title" name="Contact_Title">...

Note that you now have an underscore not a dot in the name attribute.

So I thought I'd pass in the name, including a dot, like this:

<%= Html.DropDownList(
    "Contact_Title", 
    new SelectList(Model.Titles, "Key", "Value"),
    new { name = "Contact\\.Title" })%>

But it still renders as:

<select id="Contact_Title" name="Contact_Title">...

I really (really) want this to render as:

<select id="Contact_Title" name="Contact.Title">...

In order for this to bind back to Model.Contact.Title automatically - any ideas?

IMPORTANT UPDATE

This is slightly different to my initial thoughts... it actually looks like whatever I pass as the name attribute is simply ignored...

new { name = "MYNAME" }

Still results in Contact_Title!

Any help appreciated!

解决方案

<%= Html.DropDownList(
    "Contact.Title",
    new SelectList(Model.Titles, "Key", "Value"))%>

This will render:

<select id="Contact_Title" name="Contact.Title">...

It only replaces the dot in the id as it's not valid in xhtml.
