获取时区名称

Question

我可以使用jQuery获取客户端的时区名称吗？

示例:Pacific SA标准时间,格林威治标准时间,如下所示:https://en.wikipedia.org/wiki/List_of_time_zones_by_country

Timezonelist

我可以使用jQuery获取客户端的时区名称吗？

不,jQuery只有一个日期/时间功能,即$.now().

如果你的意思是JavaScript,答案仍然是否定的.您只能获得一个时区偏移距离date.getTimezoneOffset().你无法获得时区 - 至少在所有浏览器中都没有.请参阅时区标签wiki的标题为的部分:"Time Zone != Offset"

您可以使用jsTimeZoneDetect库猜测时区,但这只是一个猜测.它可能准确也可能不准确.

你现在也可以使用moment.js和moment-timezone add.它现在支持时区猜测moment.tz.guess().

如果您可以保证您的用户在完全支持ECMAScript Internationalization API的环境中运行 ,您可以获得用户的时区,如下所示:

Intl.DateTimeFormat().resolvedOptions().timeZone

您可以查看兼容性列表,下DateTimeFormat- resolvedOptions().timezone defaults to the host environment确定哪些环境中,这将在工作.

老实说,最好的办法就是给用户一个可以选择时区的屏幕.您可以使用下拉列表,也可以使用基于地图的时区选择器 - 就像这样.您可以使用jsTimeZoneDetect作为默认值,但您的用户应该能够更改它.

此外,所有这些都将为您提供IANA时区标识符,例如America/Los_Angeles.但是您提供的示例似乎是Windows时区ID(与TimeZoneInfo.net 一起使用).你应该阅读时区标签wiki,然后还有这个问题:如何在Windows和IANA时区之间进行转换？

Answer 2

输出new Date()是Wed Aug 14 2013 22:02:13 GMT-0700 (Pacific Daylight Time),你能用吗？如果您不需要正式名称,可以使用括号中的内容

function getTimeZone() {
    return /\((.*)\)/.exec(new Date().toString())[1];
}

getTimeZone(); // Pacific Daylight Time 

Answer 3

作为另一种选择,下面是使用纯javascript获取时区的方法:

(new Date).toString().split('(')[1].slice(0, -1)

Answer 4

获取当前时区标准名称:

function getTimezoneName() {
    var timeSummer = new Date(Date.UTC(2005, 6, 30, 0, 0, 0, 0));
    var summerOffset = -1 * timeSummer.getTimezoneOffset();
    var timeWinter = new Date(Date.UTC(2005, 12, 30, 0, 0, 0, 0));
    var winterOffset = -1 * timeWinter.getTimezoneOffset();
    var timeZoneHiddenField;

    if (-720 == summerOffset && -720 == winterOffset) { timeZoneHiddenField = 'Dateline Standard Time'; }
    else if (-660 == summerOffset && -660 == winterOffset) { timeZoneHiddenField = 'UTC-11'; }

Answer 5

找到我正在使用的脚本:moment.js:

http://pellepim.bitbucket.org/jstz/

此脚本允许获取浏览器时区的名称,如下例所示:

> var timezone = jstz.determine();
> timezone.name(); 
"America/New_York"

它不是在jQuery中,但是......

Answer 6

这些链接可能会帮助您使用 Jquery 确定时区

或者下面的代码可能会帮助你

var offset = (new Date()).getTimezoneOffset();
alert(offset);

查看JSFIddle实现或了解更多说明，请访问Scott的解决方案

仅适用于时区

function get_time_zone_offset( ) {
    var current_date = new Date();
  alert(current_date);   
  //return -current_date.getTimezoneOffset() / 60;

}

警报弹出窗口也会显示时区，您可以根据您的要求重构时区，请在 JS Fiddle 中查看
