我有链接设置在一个div，所以它是一个字母和数字链接的垂直列表。

#links {
    float:left;
    font-size:9pt;
    margin-left:0.5em;
    margin-right:1em;
    position:fixed;
    text-align:center;
    width:0.8em;
}

然后我设置了这个方便的jQuery函数来保存加载的位置，然后当滚动超过该位置时将位置更改为固定。

注意:这只适用于链接在页面加载可见!!

var listposition=false;
jQuery(function(){
     try{
        ///// stick the list links to top of page when scrolling
        listposition = jQuery('#links').css({'position': 'static', 'top': '0px'}).position();
        console.log(listposition);
        $(window).scroll(function(e){
            $top = $(this).scrollTop();
            $el = jQuery('#links');
            //if(typeof(console)!='undefined'){
            //    console.log(listposition.top,$top);
            //}
            if ($top > listposition.top && $el.css('position') != 'fixed'){
                $el.css({'position': 'fixed', 'top': '0px'});
            }
            else if ($top < listposition.top && $el.css('position') == 'fixed'){
                $el.css({'position': 'static'});
            }
        });

    } catch(e) {
        alert('Please vendor admin@mydomain.com (Myvendor JavaScript Issue)');
    }
});

这就是我用jquery做的。这都是根据堆栈溢出的各种答案拼凑起来的。这个解决方案缓存选择器以获得更快的性能，并且还解决了当粘性div变得粘性时的“跳跃”问题。

在jsfiddle: http://jsfiddle.net/HQS8s/上查看它

CSS:

.stick {
    position: fixed;
    top: 0;
}

JS:

$(document).ready(function() {
    // Cache selectors for faster performance.
    var $window = $(window),
        $mainMenuBar = $('#mainMenuBar'),
        $mainMenuBarAnchor = $('#mainMenuBarAnchor');

    // Run this on scroll events.
    $window.scroll(function() {
        var window_top = $window.scrollTop();
        var div_top = $mainMenuBarAnchor.offset().top;
        if (window_top > div_top) {
            // Make the div sticky.
            $mainMenuBar.addClass('stick');
            $mainMenuBarAnchor.height($mainMenuBar.height());
        }
        else {
            // Unstick the div.
            $mainMenuBar.removeClass('stick');
            $mainMenuBarAnchor.height(0);
        }
    });
});

以下是Josh Lee的回答的扩展版本。如果你想让div在侧边栏的右边，并浮动在一个范围内(即，你需要指定顶部和底部锚位置)。它还修复了一个bug，当你在移动设备上查看这个(你需要检查左滚动位置，否则div将移出屏幕)。

function moveScroller() {
    var move = function() {
        var st = $(window).scrollTop();
        var sl = $(window).scrollLeft();
        var ot = $("#scroller-anchor-top").offset().top;
        var ol = $("#scroller-anchor-top").offset().left;
        var bt = $("#scroller-anchor-bottom").offset().top;
        var s = $("#scroller");
        if(st > ot) {
            if (st < bt - 280) //280px is the approx. height for the sticky div
            {
                s.css({
                    position: "fixed",
                    top: "0px",
                    left: ol-sl
                }); 
            }
            else
            {
                s.css({
                    position: "fixed",
                    top: bt-st-280,
                    left: ol-sl
                }); 
            }
        } else {
            s.css({
                position: "relative",
                top: "",
                left: ""
            });

        }
    };
    $(window).scroll(move);
    move();
}

我和你有同样的问题，最终制作了一个jQuery插件来解决它。它实际上解决了人们在这里列出的所有问题，而且还增加了一些可选特性。

选项

stickyPanelSettings = {
    // Use this to set the top margin of the detached panel.
    topPadding: 0,

    // This class is applied when the panel detaches.
    afterDetachCSSClass: "",

    // When set to true the space where the panel was is kept open.
    savePanelSpace: false,

    // Event fires when panel is detached
    // function(detachedPanel, panelSpacer){....}
    onDetached: null,

    // Event fires when panel is reattached
    // function(detachedPanel){....}
    onReAttached: null,

    // Set this using any valid jquery selector to 
    // set the parent of the sticky panel.
    // If set to null then the window object will be used.
    parentSelector: null
};

粘到页脚碰到div:

function stickyCostSummary() {
    var stickySummary = $('.sticky-cost-summary');
    var scrollCostSummaryDivPosition = $(window).scrollTop();
    var footerHeight = $('#footer').height();
    var documentHeight = $(document).height();
    var costSummaryHeight = stickySummary.height();
    var headerHeight = 83;
    var footerMargin = 10;
    var scrollHeight = 252;
    var footerPosition = $('#footer').offset().top;

    if (scrollCostSummaryDivPosition > scrollHeight && scrollCostSummaryDivPosition <= (documentHeight - footerHeight - costSummaryHeight - headerHeight - footerMargin)) {
        stickySummary.removeAttr('style');
        stickySummary.addClass('fixed');

    } else if (scrollCostSummaryDivPosition > (documentHeight - footerHeight - costSummaryHeight - headerHeight - footerMargin)) {
        stickySummary.removeClass('fixed');
        stickySummary.css({
          "position" : "absolute",
          "top" : (documentHeight - footerHeight - costSummaryHeight - headerHeight - footerMargin - scrollHeight) + "px"
      });
    } else {
        stickySummary.removeClass('fixed');
        stickySummary.css({
            "position" : "absolute",
            "top" : "0"
        });
    }
}

$window.scroll(stickyCostSummary);

这是另一种选择:

JAVASCRIPT

var initTopPosition= $('#myElementToStick').offset().top;   
$(window).scroll(function(){
    if($(window).scrollTop() > initTopPosition)
        $('#myElementToStick').css({'position':'fixed','top':'0px'});
    else
        $('#myElementToStick').css({'position':'absolute','top':initTopPosition+'px'});
});

你的#myElementToStick应该以position:absolute CSS属性开始。
