将上一步定义的方法作为参数传递给DynamicComponent,并将方法名作为参数传递给该方法。例如: 代码语言:txt 复制 <DynamicComponent Type="typeof(ChildComponent)" Parameters="new Dictionary<string, object> { { "methodDelegate", new MethodDelegate(InvokeMethod) }, { "methodName", "Method...
但是当跨越多个层级的时候就比较麻烦,好在Blazor提供了“Cascading values and parameters”,中文翻译为级联值和参数。 级联值和参数是通过CascadingValue组件和CascadingParameter属性注解实现的。 祖先组件使用 Blazor 框架的 CascadingValue 组件提供级联值,该组件包装组件层次结构的子树,并向其子树中的所有组件提供单个值。
builder.Services.AddLibraryCascadingParameters(); 指示开发人员调用扩展方法。 这是一种合理的替代方法,可取代指导开发人员在<RootComponent>组件中添加MainLayout组件这一环节。 级联多个值 若要在同一子树内级联多个相同类型的值,请向每个Name组件及其相应的[CascadingParameter]提供唯一的字符串。
