无法使用javascript从日期对象获取Am Pm

Question

我在javascript中有date对象，通过这个date对象，我试图获取AM或PM 。 这是日期对象Mon May 01 2017 12:43:30 GMT+0530 (India Standard Time)

根据时间，它应该按照印度标准时间中午12:43返回pm ，但返回'am'

这是我的逻辑

 var x = new Date("Mon May 01 2017 12:43:30 GMT+0530"); // (India Standard Time) var hours = x.getHours(); var hours = (hours + 24 - 2) % 24; var amPmStr = ' am'; if (hours == 0) { //At 00 hours we need to show 12 am hours = 12; } else if (hours > 12) { hours = hours % 12; amPmStr = ' pm'; } console.log(amPmStr,x) 

Answer 1

看一看，希望这可以指导您正确的方向

我从var hours = (hours + 24 - 2) % 24;删除了“ -2” var hours = (hours + 24 - 2) % 24; 既然没有意义。

 var x = new Date("05 01 2017 12:43:30") var hours = x.getHours(); var minutes = x.getMinutes(); hours = (hours + 24) % 24; var amPmStr = ' am'; if (hours < 12) { //At 00 hours we need to show 12 am hours = 12; } else if (hours >= 12 && minutes > 00) { hours = hours % 12; amPmStr = ' pm'; } console.log(amPmStr)
