ant-design RangePicker时间选择框默认值设置处理

1、
基础，直接上代码，不作过多解释

// 做这个处理是为了避免出现invalid date
 const lastStart =
      deepStartDate === '' || deepStartDate === undefined ? deepStartDate : moment(deepStartDate);
    const lastEnd =
      deepEndDate === '' || deepEndDate === undefined ? deepEndDate : moment(deepEndDate);

  <RangePicker
              value={
    
    [lastStart, lastEnd]}
              onChange={
    
    this.handleDateChange.bind(this)}
              style={
    
    {
    
     width: 230, marginLeft: 20 }}
            />
