iView + Vue，DatePicker选择日期格式处理与根据日期查询表单数据

属于个人笔记，没写demo，直接从个人的项目上面截取一部分

1.DatePicker里面的日期格式是国际的，要用format修改其中的格式

2.日期范围选择查询表单数据展示，把日期转化成秒进行大小，比较就可以了date.getTime()

3.要先判断startTime和endTime是否都存在然后在操作单个

<template>
<div>
<div class="info_option_select">
        开始日期：<DatePicker type="datetime" placeholder="请选择开始日期" format="yyyy-MM-dd HH:mm:ss"
                         @on-change="startTimeChange" :options='startTimeOptions' v-model="param.startTime"></DatePicker>
      </div>
      <div class="info_option_select">
        结束日期：<DatePicker type="datetime" placeholder="请选择结束日期" format="yyyy-MM-dd HH:mm:ss"
                         @on-change="endTimeChange" :options = 'endTimeOptions' v-model="param.endTime"></DatePicker>
      </div>
      <Button @click="searchData">查询</Button>
</div>
</template>
