一. 效果图
二. 功能介绍
支持滚动和点击选择年月。（目前只支持设置年月的最大最小值，不支持整体的最大最小值）
三. 代码
1. 在你的html中添加如下代码：
直接加载<body>里面，这里是插件渲染html的地方。
<div id="datePlugin"></div>
2. 在你的html中添加输入框：
可以是直接的一个输入框，也可以是input-group样式的。
我这里使用的时input-group，html是由JS加载的。
'<div class="item item-buydate input-group">' + '<span class="input-group-span no-border-right" id="buydate-span">申购成交时间</span>' + '<input class="txt-input txt-buydate no-border-left text-right" type="text" placeholder="请选择申购日期" readonly>' + '</div>';
3. 调用方法：
$('.item-buydate').date({ title: '申购成交时间' }); 4. JS源代码：
(function($) {$.fn.date = function(options) {var that = $(this);var docType = $(this).is('input');var nowdate = new Date();var indexY = 1,indexM = 1;var initY = parseInt((nowdate.getYear() + '').substr(1, 2));var initM = parseInt(nowdate.getMonth() + '') + 1;var yearScroll = null,monthScroll = null;$.fn.date.defaultOptions = {title: '请选择年月',beginyear: 2000, //日期--年--份开始endyear: nowdate.getFullYear(), //日期--年--份结束beginmonth: 1, //日期--月--份结束endmonth: 12, //日期--月--份结束curdate: false, //打开日期是否定位到当前日期mode: null, //操作模式（滑动模式）event: "click", //打开日期插件默认方式为点击后后弹出日期isShowByDefault: false,isSetFinancialDefaultDateValue: false}var opts = $.extend(true, {}, $.fn.date.defaultOptions, options);if (opts.isSetFinancialDefaultDateValue) {if (opts.beginyear < opts.endyear) {initY = ((opts.endyear - 1) + '').substr(2, 2);} else if (opts.beginyear = opts.endyear) {initY = (opts.endyear + '').substr(2, 2);}}if (opts.isShowByDefault) {showDatePicker()}that.bind(opts.event, showDatePicker);function showDatePicker() {createUL();init_iScrll();extendOptions();that.blur();refreshDate();bindButton();}function refreshDate() {yearScroll.refresh();monthScroll.refresh();resetInitDete();yearScroll.scrollTo(0, initY * 40, 100, true);monthScroll.scrollTo(0, initM * 40 - 40, 100, true);}function resetIndex() {indexY = 1;indexM = 1;}function resetInitDete() {if (opts.curdate) {return false;} else if (that.val() === '') {if (that.children('input').val() === '') {return false;}initY = parseInt(that.children('input').val().substr(2, 2));initM = parseInt(that.children('input').val().substr(5, 2));} else {initY = parseInt(that.val().substr(2, 2));initM = parseInt(that.val().substr(5, 2));}}function bindButton() {resetIndex();$("#yearwrapper ul li").unbind('click').click(function() {if ($(this).hasClass("placeholder")) {return false;}var target = $(this).prev('li');yearScroll.scrollToElement(target[0]);indexY = $(this).attr('data-params');$("#dateconfirm").removeClass("disabled");});$("#monthwrapper ul li").unbind('click').click(function() {if ($(this).hasClass("placeholder")) {return false;}var target = $(this).prev('li');monthScroll.scrollToElement(target[0]);indexM = $(this).attr('data-params');$("#dateconfirm").removeClass("disabled");});$("#dateshadow").unbind('click').click(function() {$("#datePage").hide();$("#dateshadow").hide();});$("#dateconfirm").unbind('click').click(function() {if ($(this).hasClass('disabled')) {return false;}if (indexY !== undefined && indexY !== '') {indexY = parseInt(parseFloat(indexY).toFixed(0));}if (indexM !== undefined && indexM !== '') {indexM = parseInt(parseFloat(indexM).toFixed(0));}var datestr = $("#yearwrapper ul li:eq(" + indexY + ")").html().substr(0, $("#yearwrapper ul li:eq(" + indexY + ")").html().length - 1) + "-" +$("#monthwrapper ul li:eq(" + indexM + ")").html().substr(0, $("#monthwrapper ul li:eq(" + indexM + ")").html().length - 1);if (docType) {that.val(datestr);that.trigger('input');} else {that.children('input').val(datestr);that.children('input').trigger('input');}$("#datePage").hide();$("#dateshadow").hide();});$("#datecancle").click(function() {$("#datePage").hide();$("#dateshadow").hide();});}function extendOptions() {$("#datePage").show();$("#dateshadow").show();}//日期滑动function init_iScrll() {var oldIndexY = parseInt(indexY.toFixed(0));var oldIndexM = parseInt(indexM.toFixed(0));var strY = $("#yearwrapper ul li:eq(" + oldIndexY + ")").html().substr(0, $("#yearwrapper ul li:eq(" + oldIndexY + ")").html().length - 1);var strM = $("#monthwrapper ul li:eq(" + oldIndexM + ")").html().substr(0, $("#monthwrapper ul li:eq(" + oldIndexM + ")").html().length - 1);yearScroll = new iScroll("yearwrapper", {snap: "li",vScrollbar: false,onScrollMove: function() {$("#dateconfirm").addClass("disabled");},onScrollEnd: function() {indexY = (this.y / 40) * (-1) + 1;$("#dateconfirm").removeClass("disabled");}});monthScroll = new iScroll("monthwrapper", {snap: "li",vScrollbar: false,onScrollMove: function() {$("#dateconfirm").addClass("disabled");},onScrollEnd: function() {indexM = (this.y / 40) * (-1) + 1;$("#dateconfirm").removeClass("disabled");}});}function createUL() {CreateDateUI();$("#yearwrapper ul").html(createYEAR_UL());$("#monthwrapper ul").html(createMONTH_UL());}function CreateDateUI() {var str = '<div id="dateshadow"></div>' +'<div id="datePage" class="page">' +'<section>' +'<div id="datetitle">' + opts.title + '</div>' +'<div id="datemark"></div>' +'<div id="datescroll">' +'<div id="yearwrapper">' +'<ul></ul>' +'</div>' +'<div id="monthwrapper">' +'<ul></ul>' +'</div>' +'</div>' +'</section>' +'<footer id="dateFooter">' +'<div id="setcancle">' +'<ul>' +'<li id="dateconfirm">确定</li>' +'<li id="datecancle">取消</li>' +'</ul>' +'</div>' +'</footer>' +'</div>'$("#datePlugin").html(str);}function createYEAR_UL() {var str = '<li class="placeholder"> </li>';for (var i = opts.beginyear;
