react-native 计算时间差
//计算时间
var sendTime = this.props.obj.send_time;
console.log(sendTime);
//当前时间
var nowTime = (new Date()).valueOf();
console.log(nowTime);
//差值
var date3 = nowTime - sendTime;
console.log(date3);
//天
var days=Math.floor(date3/(24*3600*1000))
//时
var leave1=date3%(24*3600*1000)
var hours=Math.floor(leave1/(3600*1000))
//分
var leave2=leave1%(3600*1000)
var minutes=Math.floor(leave2/(60*1000))
//秒
var leave3=leave2%(60*1000)
var seconds=Math.round(leave3/1000)
var disAndTimeText;
if(days>0){
var myText = '600m '+days+'天前'
disAndTimeText = <Text style={styles.disAndTimeText}>{myText}</Text>
}
if(days==0&&hours>0){
var myText = '600m '+hours+'小时前'
disAndTimeText = <Text style={styles.disAndTimeText}>{myText}</Text>
}
if(days==0&&hours==0&&minutes>0){
var myText = '600m '+minutes+'分钟前'
disAndTimeText = <Text style={styles.disAndTimeText}>{myText}</Text>
}
if(days==0&&hours==0&&minutes==0&&seconds>0){
var myText = '600m 刚刚'
disAndTimeText = <Text style={styles.disAndTimeText}>{myText}</Text>
}
