Mobiscroll日期选择器
每年应该以重置值00-000-0000结尾，当我单击重置按钮时，将达到重置值。如何做到这一点。
+----+-----+------+
| 31 | dec | 2014 |
| 00 | 000 | 0000 | ----->reset value
| 01 | jan | 2015 |
| 02 | jan | 2015 |
+----+-----+------+
--------------------
|ok| |reset| |cancel|
--------------------
最佳答案
在日期选择器滚动视图中添加重置值。修改其中的几行代码
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');
}
在mobiscroll.datetimebase.js中替换以下代码
formatValue: function (d) {
//return datetime.formatDate(format, getDate(d), s);
//KKN
if (d[o["m"]] != "-1" && d[o["d"]] != "0" )
