Element

当前日期之前的日期禁用

<el-date-picker v-model="form.startTime" type="date" placeholder="选择日期" :picker-options="pickerOptions"></el-date-picker>
data(){
retutn{
      pickerOptions: {
        disabledDate(time) {
          return time.getTime() < Date.now() - 8.64e7;
        },
      },
}
}

结束日期不可大于开始日期

 <el-date-picker v-model="form.startTime" type="date" placeholder="开始日期" :picker-options="pickerOptions" value-format="yyyy-MM-dd"></el-date-picker>
 <el-date-picker v-model="form.endTime" type="date" placeholder="借宿日期" :picker-options="pickerOptionsEndTime" value-format="yyyy-MM-dd"></el-date-picker>
   data() {
    let endTime = (time) => {
      return time.getTime() < new Date(this.form.startTime).getTime();
    };
    return{
        // 开始日期
      pickerOptions: {
        disabledDate(time) {
          return time.getTime() < Date.now() - 8.64e7;
        },
      },
      // 结束日期
      pickerOptionsEndTime: {
        disabledDate(time) {
          return endTime(time);
        },
      },
    }
   }

处理时间日期格式new Date()

    DateFormat() {
      var datetime = new Date();
      //月份为0-11，所以+1，月份小于10时补个0
      var year = datetime.getFullYear();
      var month = datetime.getMonth() + 1; //js从0开始取
      var date = datetime.getDate();
      var hour = datetime.getHours();
      var minutes = datetime.getMinutes();
      var second = datetime.getSeconds();
      if (month < 10) {
        month = "0" + month;
      }
      if (date < 10) {
        date = "0" + date;
      }
      if (hour < 10) {
        hour = "0" + hour;
      }
      if (minutes < 10) {
        minutes = "0" + minutes;
      }
      if (second < 10) {
        second = "0" + second;
      }
      var time =
        year +
        "年" +
        month +
        "月" +
        date +
        "日" +
        hour +
        "时" +
        minutes +
        "分" +
        second +
        "秒";
      return time;
    },

获取当前日期前N天的函数

 function getBeforeDate(n) {
        var n = n;
        var d = new Date();
        var year = d.getFullYear();
        var mon = d.getMonth() + 1;
        var day = d.getDate();
        if(day <= n) {
            if(mon > 1) {
                mon = mon - 1;
            } else {
                year = year - 1;
                mon = 12;
            }
        }
        d.setDate(d.getDate() - n);
        year = d.getFullYear();
        mon = d.getMonth() + 1;
        day = d.getDate();
        s = year + "-" + (mon < 10 ? ('0' + mon) : mon) + "-" + (day < 10 ? ('0' + day) : day);
        return s;
    }
