Blazor页面的HTML渲染加载延迟可能是由于网络连接或服务器响应时间等因素引起的。以下是一些可能的解决方法。
@inject HttpClient Http
@code {
    private string htmlContent;
    protected override async Task OnInitializedAsync()
    {
        htmlContent = await Http.GetStringAsync("https://example.com/page.html");
    }
}
    @if (!string.IsNullOrEmpty(htmlContent))
    {
        @Html.Raw(htmlContent)
    }
@inject HttpClient Http
@inject ILocalStorageService LocalStorage
@code {
    private string htmlContent;
    protected override async Task OnInitializedAsync()
    {
        htmlContent = await LocalStorage.GetItemAsync("htmlContent");
        if (string.IsNullOrEmpty(htmlContent))
        {
            htmlContent = await Http.GetStringAsync("https://example.com/page.html");
            await LocalStorage.SetItemAsync("htmlContent", htmlContent);
        }
    }
}
    @if (!string.IsNullOrEmpty(htmlContent))
    {
        @Html.Raw(htmlContent)
    }
 @inject HttpClient Http
@code {
    private string htmlContent;
    private bool isContentLoaded;
    protected override async Task OnInitializedAsync()
    {
        await LoadPageContent();
    }
    private async Task LoadPageContent()
    {
        // Load other content here
        htmlContent = await Http.GetStringAsync("https://example.com/page.html");
        isContentLoaded = true;
    }
}
    
        
    
    @if (isContentLoaded)
    {
        
            @Html.Raw(htmlContent)
        
    }
    else
    {
        
            Loading...
        
    }
这些解决方法可以帮助减少Blazor页面的HTML渲染加载延迟。根据具体情况选择适用的方法来优化页面加载速度。
