日期控件datepicker 只能选指定段日期案例

需求：日期控件只可选择本月日期，其它月份日期为灰色不可选。

 

页面：

<datepicker :language="languages[$i18n.locale]"
                            :placeholder="$t('PleaseSelect') + $t('PostingDate')"
                            format="yyyy-MM-dd"
                            name="postingDate"
                            v-validate="'required'"
                            :clear-button="false"
                            v-model="postingDate"
                            :disabledDates="disabledDates"
                            class="w-full"/>

声明（data）：

disabledDates:{
          customPredictor(date) {
            //判断如果当前月份为12月则年份+1 月份变1月
            var endYear = new Date().getFullYear();
            var endMonth = new Date().getMonth()+2;
            var startTimeMonth = new Date().getMonth()+1;
            if(startTimeMonth==12)
            {
              endYear++;
              endMonth='01';
            }

            var startTime=new Date(new Date().getFullYear()+'-'+(new Date().getMonth()+1)+'-01').getTime();
            var endTime=new Date(endYear+'-'+endMonth+'-01').getTime();
            
            if (date.getTime() < startTime||date.getTime() > endTime) { 
                return true;
            }
          }


          // 不可选今天以后的日期
          // customPredictor(date) {
          //   if (date.getTime() > (new Date()).getTime()) { 
          //       return true;
          //   }
          // }

        },

备注：

vue 中 new Date().getMonth()  得到的月份比当前月份少一个月
