• 主要关注点在于校验的方式：

<div class="timeChangeItem">
<lc-form ref="vulnTime" :rules="ruleValidate" :model="vulnTime" >
    <lc-form-item :required='true' label='有效时间：' prop='scopeTime' 
    :rules="[{ type: 'array', required: true,
    fields: {
        0: { type: 'date', required: true, message: '请选择有效时间' },
        1: { type: 'date', required: true, message: '请选择有效时间' },
          } }]">
      <lc-date-picker 
        type="datetimerange" 
        format="yyyy-MM-dd HH:mm:ss" 
        valueFormat="yyyy-MM-dd HH:mm:ss"
        v-model="vulnTime.scopeTime"
        @on-change="handleTimeChange"
        placeholder="开始时间           -结束时间" 
        style="width: 300px">
      </lc-date-picker>
    </lc-form-item>
 </lc-form>
</div>
<script>
	data:{
		return{
			vulnTime:{
				scopeTime:'',
			}
		}
	},
	methods:{
		handleTimeChange() {	     
	      if (startTime && endTime) {
	        this.vulnTime.scopeTime = [
	          moment(this.vulnTime.scopeTime[0]).format('YYYY-MM-DD HH:mm:ss'),
	          moment(this.vulnTime.scopeTime[1]).format('YYYY-MM-DD HH:mm:ss'),
	        ];
	      } else {
	        this.vulnTime.scopeTime = [];
	      }
	    },	
	}
}
</script>

• 这样的校验方式会导致时间组件框一直处于提交状态，无法正常通过校验；

• 校验改正：自定义validator方法进行校验；

<div class="timeChangeItem">
 <lc-form-item :required='true' label='有效时间：' prop='scopeTime'>
    <lc-date-picker 
      type="datetimerange" 
      format="yyyy-MM-dd HH:mm:ss" 
      valueFormat="yyyy-MM-dd HH:mm:ss"
      v-model="vulnTime.scopeTime"
      @on-change="handleValidDateChange"
      placeholder="开始时间           -结束时间" 
      style="width: 300px">
    </lc-date-picker>
  </lc-form-item>
</div>
<script>
data:{
	const validTimeRange = (rule, value, callback) => {
      if (!this.vulnTime.scopeTime[0] && !this.vulnTime.scopeTime[1]) {
        callback(new Error('请输入有效时间'));
      } else {
        callback();
      }
    };
	return{
		vulnTime:{
			scopeTime:'',
		},
		ruleValidate: {
	        scopeTime: [
	          { validator: validTimeRange },
	        ],
      	},
	}
},
methods:{
	handleTimeChange() {	     
	      if (startTime && endTime) {
	        this.vulnTime.scopeTime = [
	          moment(this.vulnTime.scopeTime[0]).format('YYYY-MM-DD HH:mm:ss'),
	          moment(this.vulnTime.scopeTime[1]).format('YYYY-MM-DD HH:mm:ss'),
	        ];
	      } else {
	        this.vulnTime.scopeTime = [];
	      }
	    },	
}
</script>
