Razor组件加载完毕如何执行回调

Razor 组件加载完毕如何执行回调？

参考StackOverflow

1.重写 Razor 组件的 OnInitializedAsync()方法

@code {
    void SomeStartupMethod()
    {
        // Do Some Work
    }

    Task SomeStartupTask()
    {
        // Do some task based work
        return Task.CompletedTask;
    }

    protected override async Task OnInitializedAsync()
    {
        SomeStartupMethod();
        await SomeStartupTask();
    }
}

2.重写 Razor 组件的 OnAfterRender()方法

@code{
    protected override void OnAfterRender(bool firstRender)
    {
        // execute conditionally for loading data, otherwise this will load
        // every time the page refreshes
        if(firstRender)
        {
            // Do work to load page data and set properties
        }
    }
}
