Question

我有一个对象数组作为输入

function showPosts(results, noOfPosts){

                    if(currentPost!=noOfPosts){
                        if(params.detail) {
                        var dtStr = "-";//format(dt);
                        $("#container").addClass("details");
                        $("#container").append('<div class="post"><div class="title">'+results[currentPost].title+'<i>'+dtStr+'</i></div><div class="content">'+results[currentPost].content.extended+'</div></div>');
                        countPost++;
                    } else {
                        $("#container").append('<div class="post"><span class="title">'+results[currentPost].title+'</span> - '+results[currentPost].content.brief+'</div>');
                        countPost++;
                        }
                    }
                    else
                        countPost=0;
                        $("#container").removeClass("class");


                }

                setInterval(function(){
                    showPosts(results, noOfPosts)
                },3000)

我必须以3秒的间隔一次只显示3个帖子，假设输入有8个帖子，那么它应该先显示3个，然后显示3个然后是2个，然后再返回3个帖子等等。

我试过这个：

public class DefaultRegistry : Registry
{
    public DefaultRegistry() {
        Scan(
            scan => {
                scan.Assembly("MyAssembly");
                scan.WithDefaultConventions();
            });

        For<IContext<SomeClass>>().Use<MyContext>();
    }
}
