在属性名 - 用一个自定义属性DropDownListFor？ [英] DropDownListFor with a custom attribute with - in attribute name?

问题描述

问：我需要创建一个DropDownList是这样的：

Question: I need to create a dropdownlist like this:

<select id="ddCustomers" data-placeholder="Choose a customer" class="chzn-select" style="width:350px;" tabindex="1" multiple>

现在，我可以添加自定义属性是这样的：

Now I can add custom attributes like this:

@Html.DropDownListFor(m => m.Id, Model.Values, new { @disabled = "disabled" })

不幸的是，如果有一个 - 在变量名，那么它不编译

Unfortunately, if there is a "-" in the variable name, then it doesn't compile.

@Html.DropDownListFor(m => m.Id, Model.Values, new { @disabled = "disabled", @data-placeholder = "whatever" })

和怎么样的多，它没有属性值？

And what about the multiple, which has no attribute value ?

如果我传递一个字典或NameValueColletion代替新{@disabled =已禁用} ，那么它输出NameValueColletion /词典的属性...

If I pass a Dictionary or a NameValueColletion instead of the new { @disabled = "disabled" }, then it outputs the properties of the NameValueColletion/Dictionary...

我如何将属性与属性键特殊字符？

How can I pass attributes with special characters in the attribute key ?

推荐答案

使用下划线代替

@data_placeholder = "whatever"

由于MVC3_替换为 - 渲染时。

Since Mvc3 "_" is replaced with "-" when rendered.

作为底线不是在HTML属性名接受这工作得很好。

This works fine as underscores are not acceptable in attribute names in html.
