Mobiscroll日期选择器
每年都应以复位值00-000-0000结束，当我点击复位按钮时，复位值就会实现。如何实现这一点。
+----+-----+------+
| 31 | dec | 2014 |
| 00 | 000 | 0000 | ----->reset value
| 01 | jan | 2015 |
| 02 | jan | 2015 |
+----+-----+------+
--------------------
|ok| |reset| |cancel|
--------------------
答案 0 :(得分：1)
在日期选择器滚动视图中添加重置值。修改几行代码 mobiscroll.util.datetime.js，mobiscroll.datetimebase.js
在mobiscroll.datetimebase.js中，
under variable defaults={}, add partialDate : false,
add reset values in a wheel generating loop: for (k = 0; k < 3; k++) {},
if (s.partialDate)
{
keys.push(-1);
values.push('0000');
}
替换mobiscroll.datetimebase.js中的以下代码
formatValue: function (d) {
//return datetime.formatDate(format, getDate(d), s);
//KKN
if (d[o["m"]] != "-1" && d[o["d"]] != "0" )
