问题描述
我正在以两种不同的格式在数据库中插入日期。
I'm inserting a date in a database in two different format.
这是插入日期时间
var mydate;
mydate = new Date();
document.getElementById('clockinhour').value = mydate.toISOString().slice(0, 19).replace('T', ' ');
输出A
2017-06-21 20:14:31
这是插入为varchar:
document.getElementById('clocked_in_time').value = Date();
输出B
Wed Jun 21 2017 16:14:31 GMT-0400 (Eastern Standard Time)
输出B是正确的时间,但我需要显示输出A.什么原因导致转换为ISOString时的时间变化?我该如何解决这个问题?
Output B is the correct time but I need to display output A. What causes the time to change when converted toISOString? How can I fix this?
推荐答案
在这是插入日期时间阻止你的 slice
正在剥离时区部分( Z
末尾的 toISOString
输出):
In your this is inserting as Datetime block your slice
are stripping of the timezone part (the Z
at the end of toISOString
output):
document.getElementById('clockinhour').value = mydate.toISOString().slice(0, 19).replace('T', ' ');
正如@RobG在评论部分所指出的, toISOString
应始终以UTC格式返回日期( Z
或 +00:00
)。
As pointed out by @RobG in the comments section, toISOString
should always return the date in UTC (Z
or +00:00
).
时间更改,因为当您调用 toISOString
时,它会转换为UTC。
The time "changes" because it is converted to UTC when you calls toISOString
.
如果你想在你的时区获得ISO日期,你应该看看这两个问题:和
If you want to get ISO date in your timezone, you should take a look in these two questions: How to ISO 8601 format a Date with Timezone Offset in JavaScript? and How to format a JavaScript date
