minDate Bug

[MrZhangFengfeng]

1. While setting a minDate(2017/09/07),then click the year to choose a date latter than minDate.

2. Then,I don‘t want this date. I click the year to get back.

3. But now,I can't choose the minDate's year.(2017) I have to choose 2018 then back to 2017.

In Chinese

当minDate的参数为2017/08/01时，在UIDateTimePicker控件，先依据年份查一个日期：如2022/01/20。

然后选择了而一个后面的日期，但是又不想要这个日期了，想选前面的minDate所在年份的日期。

再使用年份查找到2017/07/12的时候。就无法选择2017年的年份。必需先选择2018，然后再回退到2017年。

我刚刚也遇到这个问题了，查看源码，找到原因，这是一个小bug

压缩版的 min.js：

把 this.onRenderYear=function(o){ ......... } 中的

if(o<this.startDate || n>r ){
   p.push("disabled")
} 

修改为 ：

if(o.getUTCFullYear()<this.startDate.getUTCFullYear() || n>r){
   p.push("disabled")
}

就可以了。

未压缩的js:

 this.onRenderYear = function (date) {
      var render = (options.onRenderYear || function () { return []; })(date);
      var res = ['year'];
      if (typeof render === 'string') {
        render = [render];
      }
      if (this.date.getUTCFullYear() === date.getUTCFullYear()) {
        res.push('active');
      }
      var currentYear = date.getUTCFullYear();
      var endYear = this.endDate.getUTCFullYear();
      if (date < this.startDate || currentYear > endYear) {
        res.push('disabled');
      }
      return res.concat((render ? render : []));
    }

修改为：

this.onRenderYear = function (date) {
      var render = (options.onRenderYear || function () { return []; })(date);
      var res = ['year'];
      if (typeof render === 'string') {
        render = [render];
      }
      if (this.date.getUTCFullYear() === date.getUTCFullYear()) {
        res.push('active');
      }
      var currentYear = date.getUTCFullYear();
      var startYear =  this.startDate.getUTCFullYear();
      var endYear = this.endDate.getUTCFullYear();
      if (currentYear < startYear || currentYear > endYear) {
        res.push('disabled');
      }
      return res.concat((render ? render : []));
    }

即可！
