所以，

我正在创建一个基于Coda Slider的垂直滑块。尽管我对 Jquery 的了解非常有限，但我已经设法将滑块全部设置好，但有一个重大问题：.before 和 .after 动画（由“左”和“右”控制，或者，在这种情况下, "up" 和 "down" 与我添加的 "up" 和 "down" DIV 没有关联。我喜欢单击 "up" div 以使滑块向上滚动到上一张幻灯片.

我仍在修改脚本，但我有一种感觉，鉴于我缺乏使用 Jquery 的经验，我可能会受到 SO 的摆布来解决这个问题。

任何想法都非常感谢！

我的滑块javascript：

$(document).ready(function () {

var $panels = $('#slider .scrollContainer > div');
var $container = $('#slider .scrollContainer');

// if false, we'll float all the panels left and fix the width 
// of the container
var horizontal = false;

// float the panels left if we're going horizontal
if (horizontal) {
    $panels.css({
        'float' : 'left',
        'position' : 'relative' // IE fix to ensure overflow is hidden
    });

    // calculate a new width for the container (so it holds all panels)
    $container.css('width', $panels[0].offsetWidth * $panels.length);
}

// collect the scroll object, at the same time apply the hidden overflow
// to remove the default scrollbars that will appear
var $scroll = $('#slider .scroll').css('overflow', 'hidden');

// apply our left + right buttons
$scroll
    .before('<div id="uptopdiv" />')
    .after('<img class="scrollButtons right" src="images/scroll_right.png" />');

// handle nav selection
function selectNav() {
    $(this)
        .parents('ul:first')
            .find('a')
                .removeClass('selected')
            .end()
        .end()
        .addClass('selected');
}

$('#slider .navigation').find('a').click(selectNav);

// go find the navigation link that has this target and select the nav
function trigger(data) {
    var el = $('#slider .navigation').find('a[href$="' + data.id + '"]').get(0);
    selectNav.call(el);
}

if (window.location.hash) {
    trigger({ id : window.location.hash.substr(1) });
} else {
    $('ul.navigation a:first').click();
}

// offset is used to move to *exactly* the right place, since I'm using
// padding on my example, I need to subtract the amount of padding to
// the offset.  Try removing this to get a good idea of the effect
var offset = parseInt((horizontal ? 
    $container.css('paddingTop') : 
    $container.css('paddingLeft')) 
    || 0) * -1;


var scrollOptions = {
    target: $scroll, // the element that has the overflow

    // can be a selector which will be relative to the target
    items: $panels,

    navigation: '.navigation a',

    // selectors are NOT relative to document, i.e. make sure they're unique
    prev: 'img.left', 
    next: 'img.right',

    // allow the scroll effect to run both directions
    axis: 'xy',

    onAfter: trigger, // our final callback

    offset: offset,

    // duration of the sliding effect
    duration: 500,

    // easing - can be used with the easing plugin: 
    // http://gsgd.co.uk/sandbox/jquery/easing/
    easing: 'swing'
};

// apply serialScroll to the slider - we chose this plugin because it 
// supports// the indexed next and previous scroll along with hooking 
// in to our navigation.
$('#slider').serialScroll(scrollOptions);

// now apply localScroll to hook any other arbitrary links to trigger 
// the effect
$.localScroll(scrollOptions);

// finally, if the URL has a hash, move the slider in to position, 
// setting the duration to 1 because I don't want it to scroll in the
// very first page load.  We don't always need this, but it ensures
// the positioning is absolutely spot on when the pages loads.
scrollOptions.duration = 1;
$.localScroll.hash(scrollOptions);

});

想出如何使用不太复杂的脚本来实现相同的效果：

$(function() {
var y=0;
$(".down").click(function(e){
    e.preventDefault();
    $("#container").animate({scrollTop: y+=250}, 500);
})
$(".up").click(function(e){
    e.preventDefault();
    $("#container").animate({scrollTop: y-=250}, 500);
})        
})

JsFiddle 在这里。
