                  disabledDate: (time) =>
                    time.getTime() <
                    new Date(new Date().setHours(0, 0, 0, 0))

              :picker-options="{selectableRange:`00:00:00-${form.stopTime ? form.stopTime + ':00' : '23:59:59'}`}">
              </el-time-picker>
            </el-form-item>
          </el-col>
          <el-col :span="12">

 3、设置YYYY-MM-dd HH:mm:ss格式指定时间之前不可选

<el-col :span="12">
            <el-form-item label="停机时间" prop="enterTime">
              <el-date-picker v-model="form.enterTime" type="datetime" :disabled="this.disabled" placeholder="请选择进车时间" align="right" :value-format="'yyyy-MM-dd HH:mm'"
                style="width: 100%" :picker-options="pickerOptions">
              </el-date-picker>
            </el-form-item>
          </el-col>
          <el-col :span="12">
            <el-form-item label="结束时间" prop="stopTime">
              <el-date-picker v-model="form.stopTime" type="datetime" :disabled="this.disabled" placeholder="请选择结束时间" align="right" :value-format="'yyyy-MM-dd HH:mm'"
                style="width: 100%" :picker-options="pickerOptions" @change="pickerOptionsEnd(form.enterTime,form.stopTime)">
              </el-date-picker>
            </el-form-item>
          </el-col>

// 结束时间不能小于开始时间
        pickerOptionsEnd(start,end){
          console.log(start)
          console.log(end)
          if(Date.parse(end )<= Date.parse(start) ) {
            this.form.stopTime = ''
            this.$modal.msgError("结束时间不能小于停机时间");
          }
        },

 4、element 日期时间组件，限制日期时间选择范围，不能选择早于当前的时间

vue代码

<el-col :span="12">
            <el-form-item label="开始时间" prop="enterTime">
              <el-date-picker v-model="form.enterTime" type="datetime" :disabled="this.disabled" placeholder="请选择开始时间" align="right" :value-format="'yyyy-MM-dd HH:mm:ss'"
                style="width: 100%" :picker-options="pickerOptions">
              </el-date-picker>
            </el-form-item>
          </el-col>
          <el-col :span="12">
            <el-form-item label="结束时间" prop="stopTime">
              <el-date-picker v-model="form.stopTime" type="datetime" :disabled="this.disabled" placeholder="请选择结束时间" align="right" :value-format="'yyyy-MM-dd HH:mm:ss'"
                style="width: 100%" :picker-options="pickerEndOptions">
              </el-date-picker>
            </el-form-item>
          </el-col>

js代码 

data() {
      return {
// 表单参数
        form: {
          stopTime:"",
        },
// 日期限制
        pickerEndOptions: {
          disabledDate: (time) => {
            if (this.form.enterTime) {
              const st = this.form.enterTime.split(' ')[1];
              let dateTime = new Date(this.form.enterTime);
              let startDateTime = dateTime.setDate(dateTime.getDate() - (st=='00:00:00'? 0: 1));
              return (
                time.getTime() < new Date(startDateTime).getTime()
              );
            }
          },
          // 限制时间
          selectableRange: []
          
        },
}
}

监听 

watch: {
      'form.stopTime':{
        handler(newValue, oldValue) {
          if(this.form.enterTime.split(" ")[0] === newValue.split(" ")[0]){
            const st = this.form.enterTime.split(' ')[1] + ":00";
            console.log(st)
            this.pickerEndOptions.selectableRange = [`${st} - 23:59:59`];
          }else{
            this.pickerEndOptions.selectableRange = [`00:00:00 - 23:59:59`];
          }
        }
      }
    },
