返回值
¥Return value
就地更改 Date 对象,并返回其新的 timestamp。如果参数为 NaN(或获取 coerced 到 NaN 的其他值,例如 undefined),则日期设置为 失效日期,并返回 NaN。
¥Changes the Date object in place, and returns its new timestamp. If a parameter is NaN (or other values that get coerced to NaN, such as undefined), the date is set to Invalid Date and NaN is returned.
描述
¥Description
如果不指定 msValue 参数,则使用从 getUTCMilliseconds() 方法返回的值。
¥If you do not specify the msValue parameter, the value returned from the
getUTCMilliseconds() method is
used.
如果你指定的参数超出预期范围,setUTCSeconds() 会尝试相应地更新 Date 对象中的日期信息。例如,如果对 secondsValue 使用 100,则 Date 对象中存储的分钟将增加 1,秒将使用 40。
¥If a parameter you specify is outside of the expected range,
setUTCSeconds() attempts to update the date information in the
Date object accordingly. For example, if you use 100 for
secondsValue, the minutes stored in the Date object will be
incremented by 1, and 40 will be used for seconds.
