• 如何建立一个可再使用的具有动态内容的超文本
原标题:How to create a reusable piece of HTML with dynamic contents

我试图制造可再使用的超文本碎片,我愿意接受额外的超文本作为某种参数。

My reusable code is

<div class="dialog" id="@Model.HtmlId">

  <!-- My reusable code needs to go here -->
</div>

形成部分观点是容易的,但问题是,部分观点接受一种模式作为参数。

我目前的解决办法令人费解。

@Html.Partial("_startDialog", new { HtmlId="someIdGoesHere" });

<form>
  <!-- Some form elements go here -->
</form>

@Html.Partial("_endDialog");

因此

<div class="dialog" id="@Model.HtmlId">

  <form>
    <!-- Some form elements go here -->
  </form>
</div>

我怎么能够这样做。 授权为:

这应当做到:

public class MvcDialog : IDisposable
{
    public MvcDialog(ViewContext context, IDictionary<string, object> htmlAttributes)
    {
        this.context = context;
        this.htmlAttributes = htmlAttributes;

        Begin();
    }

    private ViewContext context;
    private IDictionary<string, object> htmlAttributes;
    private TagBuilder tag;
    private bool disposed;

    protected virtual void Begin()
    {
        tag = new TagBuilder("div");
        tag.MergeAttributes(htmlAttributes);
        tag.AddCssClass("dialog");

        context.Writer.Write(tag.ToString(TagRenderMode.StartTag));
    }

    public virtual void End()
    {
        Dispose(true);
    }

    protected virtual void Dispose(bool disposing)
    {
        if (!disposed)
        {
            disposed = true;
            context.Writer.Write(tag.ToString(TagRenderMode.EndTag));
        }
    }

    public void Dispose()
    {
        Dispose(true);
        GC.SuppressFinalize(this);
    }
}

public static class MvcDialogExtensions
{
    public static MvcDialog Dialog(this HtmlHelper self)
    {
        return Dialog(self, new RouteValueDictionary());
    }
    public static MvcDialog Dialog(this HtmlHelper self, object htmlAttributes)
    {
        return Dialog(self, new RouteValueDictionary(htmlAttributes));
    }
    public static MvcDialog Dialog(this HtmlHelper self, IDictionary<string, object> htmlAttributes)
    {
        return new MvcDialog(self.ViewContext, htmlAttributes);
    }
}

使用:

@using (Html.Dialog(new { id = "mightyDialog" }))
{
    <text>awesome content</text>
}
