我期待着在网页底部附近的用户浏览时,形成静态菜单。
原标题:I am looking to create a static menu when a user scrolls near the bottom of the page

利用Javascript, 更理想的是,如果用户处于某一页的高度,我就能够触发 d的相对性。 当你向一个故事的底部roll时,纽约时代就是一个例子,一个叫喊另一个新闻故事的人,如果你 up倒的话,就会消失。

最佳回答

我认为,你想要的方法是:

$(document).scroll()    // event triggered whenever the page is scrolled
$(document).height()    // gets the height of the entire page
$(window).height()      // gets the height of the current window
$(document).scrollTop() // gets the top position currently visible

如果窗口是来自底层的100个餐厅,则你可以撰写显示碎块的方法:

$(document).scroll(function() {
    var scrollBottom = $(document).scrollTop() + $(window).height();
    var height = $(document).height();
    if (scrollBottom > height - 100)
        $("div").show();
    else
        $("div").hide();
});
