Question

我是umbraco和c＃的新手，我在umbraco razor中创建了一个博客列表，但是如何使按钮的功能更多？

我希望在用户单击按钮时将更多5个项目加载到列表中。一种方法是用户单击按钮更新查询，但是我需要刷新页面。

任何帮助都将是一件好事，因为我坚持使用此工具，并且不知道如何在umbraco中进行此操作。

@{
    var selection = Model.Content.Children().Where(x => x.IsVisible()).Take(5).ToList();
}

        @while(selection.Any()){

                    var oneItem = selection.First();
                    selection.Remove(oneItem);

可能是这样的：

@{
    int page = int.TryParse(Request["page"], out page) ? page : 0;
    int pageSize = 5;

    var selection = Model.Content
        .Children()
        .Where(x => x.IsVisible())
        .Skip(page * pageSize)
        .Take(pageSize)
        .ToList();
}

<div class="container-fluid">
    ...
</div>

<a href="@Request.RawUrl.Split('?')[0]?page=@(page + 1)">
    Load next @pageSize results
</a>
