js代码：


//滑动插件 by - mantou qq:
; (function ($) {
$.fn.sliderDate = function (setting) {
var defaults = {
callback: false //默认回调函数为false
}
//如果setting为空，就取default的值
var setting = $.extend(defaults, setting);
this.each(function () {
//插件实现代码
//var $sliderDate = $(".slider-date");
var $sliderDate = $(this);
var $sliderBar = $sliderDate.find(".slider-bar");
var $sliderBtn = $sliderDate.find(".slider-bar-btn");
var liWid = + ; //单个li的宽度
//滚动指定的位置
var sliderToDes = function (index) {
//最大不能超过
if (index > ) {
index = ;
}
//最小不能小于
if (index < ) {
index = ;
}
//背景动画
$sliderBar.animate({
"width": liWid * (index + )
}, );
//执行回调
if (setting.callback) {
setting.callback(index);
}
};
//点击 - 滚动到指定位置
$sliderDate.on('click', "li", function (e) {
//执行滚动方法
sliderToDes($(this).index());
});
//拖动 - 滚动到指定位置
$sliderBtn.on('mousedown', function (e) {
var $this = $(this);
var pointX = e.pageX - $this.parent().width();
var wid = null;
//拖动事件
$(document).on('mousemove', function (ev) {

if (wid > && wid < ) {
$sliderBar.css("width", wid);
}
}).on('mouseup', function (e) {
$(this).off('mousemove mouseup');
var index = Math.ceil(wid / liWid) - ;
sliderToDes(index);
});
});
});
}
})(jQuery);
$(function () {
function a(index) {
console.log(index + );
}
$("#slider-date-").sliderDate({ callback: a });
function b(index) {
console.log(index + );
}
$("#slider-date-").sliderDate({ callback: b });
function c(index) {
console.log(index + );
}
$("#slider-date-").sliderDate({ callback: c });
});

以上代码很简单吧，希望大家能够喜欢。
