移动端类似IOS的滚动年月控件（需要jQuery和iScroll）

http://www.cnblogs.com/ccblogs/p/5260949.html

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：

复制代码
(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
