跨浏览器Javascript XML解析[关闭](Cross-Browser Javascript XML Parsing)

 大约一个月前我有同样的问题，我完成了使用这种扩展方法 
 
public static class AttributesExtensions
{
    public static RouteValueDictionary DisabledIf(
        this object htmlAttributes, 
        bool disabled
    )
    {
        var attributes = new RouteValueDictionary(htmlAttributes);
        if (disabled)
        {
            attributes["disabled"] = "disabled";
        }
        return attributes;
    }
}
 
 之后你可以像这样使用它 
 
@Html.TextBoxFor(
    model => model.Street, 
    new { @class = "" }.DisabledIf(Model.StageID==(int)MyEnum.Sth)
)
 
 编辑 （ Paul的评论之后 ）： 
 
 data-xxx html属性的使用可以通过使用System.Web.Routing.RouteValueDictionary类的构造函数来挖掘，因为下划线不会自动转换为减号。 
 
 改为使用方法System.Web.Mvc.HtmlHelper.AnonymousObjectToHtmlAttributes ：将解决此问题。 
 
 更新代码 （仅限扩展方法主体） 
 
var attributes = HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes);
if (disabled)
{
    attributes["disabled"] = "disabled";
}
return attributes;

I have the same problem about month ago and I finished by using this extension method for it
 
public static class AttributesExtensions
{
    public static RouteValueDictionary DisabledIf(
        this object htmlAttributes, 
        bool disabled
    )
    {
        var attributes = new RouteValueDictionary(htmlAttributes);
        if (disabled)
        {
            attributes["disabled"] = "disabled";
        }
        return attributes;
    }
}
 
And after that you can use it like this
 
@Html.TextBoxFor(
    model => model.Street, 
    new { @class = "" }.DisabledIf(Model.StageID==(int)MyEnum.Sth)
)
 
EDIT (after Paul's comment):
 
The using of data-xxx html attributes may be mined by using the constructor of the System.Web.Routing.RouteValueDictionary class, since underscores will not be automatically converted to minus sign.
 
Use the method System.Web.Mvc.HtmlHelper.AnonymousObjectToHtmlAttributes instead: will solve this issue.
 
UPDATED CODE (Extension method body only)
 
var attributes = HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes);
if (disabled)
{
    attributes["disabled"] = "disabled";
}
return attributes;
