Component Dom Manage

Element Reference

<input @ref="textInput" />

@code {
 ElementReference textInput;

 //use
 textInput.FocusAsync();
}

HTML head

直接放在页面中即可

<HeadContent>
  <meta property="og:title" content="@BlogPost.Title" />
 <meta property="og:description" content="@(new string(BlogPost.Text.Take(100).ToArray()))" />
 <meta property="og:image" content= "@($"{_navman.BaseUri}/pathtoanimage.png")" />
 <meta property="og:url" content="@_navman.Uri" />
 <meta name="twitter:card" content="@(new string(BlogPost.Text.Take(100).ToArray()))" />
</HeadContent>

Virtualize component

Virtualize is a component in Blazor that will make sure that it only renders the components or rows that can fit the screen. If you have a large list of items, rendering all of them will have a big impact on memory.

The Virtualize component works just like a foreach loop.

<ul>
 @foreach (var p in posts)
 {
 <li><a href="/Post/@p.Id">@p.Title</a></li>
 }
</ul>

same as

<Virtualize Items="posts" Context="p">
 <li><a href="/Post/@p.Id">@p.Title</a></li>
</Virtualize>
