根据天数和月数显示时间戳?

标签: javascript jquery timeago

我正在使用jquery.timeago插件来显示时间戳。我已将其修改为今天显示为Today 06:56。它工作正常。请查看this fiddle

现在我想显示{3}的Monday 06:56。所以超过3天的时间戳我希望以日期名称and time-stamps older than 3 months it should be dd-mmm-yyyy`的格式显示它。

请在substitute()的{​​{1}}中找到以下修改内容。

jquery.timeago

如何以特定格式显示超过3天且超过3个月的时间戳???

答案 0 :(得分:0)

请查看以下jquery.timeago插件代码,了解以下要求: - 今天应显示Today <time>, - 超过3天的时间应为<Dayname> <time>, - 超过3个月的时间应为DD-MON-YYYY和 - 超过1。5年,应该是YYYY
