这种模式叫做 Infinite Scroll, 各种框架和类库中都有比较成熟的实现,可以参考一下

思路很简单(其实实现也很简单),就是ajax后台请求数据,插入到文档后面,至于事你后台渲染好的html字符串还是后端之提供数据然后js进行渲染就无所谓

$.ajax({
    ....//略
    success:function(data){
        $('body').append(data)//这个意思
    },
    ...
})

可以监视滚动条事件,距离底部100px就开始加载

    $(window).scroll(function() {
        if ($(document).scrollTop() + $(window).height() > $(document).height() - 100) {
            $.get(url, function(data) {
                $('#list').append(data);
            });
        }
    });

监听滚动事件,在回调函数里加载更多图片

用iScroll.js配合ajax请求数据可以实现上拉加载,下拉刷新,可以试一试。

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
