Blazor Webassembly多标签页实现非iframe的实现

前面用iframe实现了多标签页,这次是不用iframe实现的多标签页.参考了一下Ant Design Blazor.
基本功能已经都实现了不论是标签滚动、激活、左移、右移、关闭其他，还是在内容页跳转、新增、关闭标签都有实现。
已经可以用来做实际项目

实现原理是新建一个类继承RouteView,在此类里面的Render方法中可以通过RouteData获取当前路由对应的对象.然后生成RenderFragment.
然后将其保存到List中,然后循环显示出来.对于未激活的通过display:none隐藏就可以了,这样哪怕切换标签状态也是保存的并不会刷新

    public class ReuseTabsRouteView : RouteView     {         [Inject]         public TabSetTool TabSetTool { get; set; }          [Inject]         public NavigationManager Navmgr { get; set; }                   protected override void Render(RenderTreeBuilder builder)         {             var layoutType = RouteData.PageType.GetCustomAttribute<LayoutAttribute>()?.LayoutType ?? DefaultLayout;              var body = CreateBody(RouteData, Navmgr.Uri);              builder.OpenComponent<CascadingValue<ReuseTabsRouteView>>(0);             builder.AddAttribute(1, "Name", "RouteView");             builder.AddAttribute(2, "Value", this);              builder.AddAttribute(3, "ChildContent", (RenderFragment)(b =>             {                 b.OpenComponent(20, layoutType);                 b.AddAttribute(21, "Body", body);                 b.CloseComponent();             }));              builder.CloseComponent();             var url = "/" + Navmgr.ToBaseRelativePath(Navmgr.Uri);             if (url != "/#")             {                 var selTab = TabSetTool.Pages.FirstOrDefault(m => m.Url == url && (m.Title == TabSetTool.Title || string.IsNullOrEmpty(m.Title)));                 if (selTab == null)                 {                     TabSetTool.Pages.Add(new Tab                     {                         Body = body,                         Url = url,                         Title = TabSetTool.Title,                         IsActive = true,                     });                 }                 else                 {                     selTab.Title = TabSetTool.Title;                     selTab.Body = body;                     selTab.IsActive = true;                 }             }         }          private RenderFragment CreateBody(RouteData routeData, string url)         {             return builder =>             {                 builder.OpenComponent(0, routeData.PageType);                 foreach (var routeValue in routeData.RouteValues)                 {                     builder.AddAttribute(1, routeValue.Key, routeValue.Value);                 }                 builder.CloseComponent();             };         }       } 

App.razor中将RouteView改成ReuseTabsRouteView.

另外要注意TabSet中一定要有

[CascadingParameter(Name = "RouteView")] public ReuseTabsRouteView RouteView { get; set; } 

这两句,要不然页面会不更新
