我可以使用jQuery获取客户端的时区名称吗?
没有。 jQuery只有一个日期/时间函数,即$.now()
。
如果您的意思是 JavaScript ,答案仍然是否。您只能从date.getTimezoneOffset()
获取偏移量的时区。你无法获得时区 - 至少在所有浏览器中都没有。请参阅the timezone tag wiki标题为"Time Zone != Offset"
您可以使用jsTimeZoneDetect库在时区猜测,但这只是猜测。它可能准确也可能不准确。
现在,您也可以使用moment.js添加moment-timezone。它现在支持使用moment.tz.guess()
进行时区猜测。
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,您可以像这样获取用户的时区:
Intl.DateTimeFormat().resolvedOptions().timeZone
您可以查看DateTimeFormat
- resolvedOptions().timezone defaults to the host environment
下的compatibility table,以确定适用的环境。
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 - like this one。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(用于.net中的TimeZoneInfo
)。您应该阅读the timezone tag wiki,然后再阅读这个问题:How to translate between Windows and IANA time zones?

new Date()
的输出为Wed Aug 14 2013 22:02:13 GMT-0700 (Pacific Daylight Time)
,您可以使用它吗?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

下面的替代方法是使用纯javascript 获取时区的方法:
(new Date).toString().split('(')[1].slice(0, -1)

获取当前时区标准名称:

var timeWinter = new Date(Date.UTC(2005, 12, 30, 0, 0, 0, 0));

此脚本允许获取浏览器时区的名称,如下例所示:

无法想到使用Jquery做任何事情。您可以使用PHP获取远程用户国家/地区名称,然后将输出比较为:
1)应用节约时间(不多)的一系列国家。
2)当前日期。
获取用户所在国家/地区:
function visitor_country() {
$ip = $_SERVER["REMOTE_ADDR"];
if(filter_var(@$_SERVER['HTTP_X_FORWARDED_FOR'], FILTER_VALIDATE_IP))
$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
if(filter_var(@$_SERVER['HTTP_CLIENT_IP'], FILTER_VALIDATE_IP))
$ip = $_SERVER['HTTP_CLIENT_IP'];
$result = @json_decode(file_get_contents("http://www.geoplugin.net/json.gp?ip=" . $ip))
->geoplugin_countryName;
return $result <> NULL ? $result : "Unknown";
}
echo visitor_country(); // Output Country name [Ex: United States]
?>

这些链接可能会帮助您timeZone using Jquery
或以下代码可能会帮助您解决问题
var offset = (new Date()).getTimezoneOffset();
alert(offset);
结帐JSFIddle实施或进一步说明请Solution访问Scott
仅适用于时区
function get_time_zone_offset( ) {
var current_date = new Date();
alert(current_date);
//return -current_date.getTimezoneOffset() / 60;
}
警告弹出窗口也会显示时区,你可以根据你的要求重新计算,在JS Fiddle中查看

我知道这个问题已经过时了,但我想出了一个小小的解决方案:
(new Date).toLocaleString('en-US', {
hour12: false,
hour: '2-digit',
timeZoneName: 'long'
}).replace(/^\d\d /, '');
我还没有对此进行过广泛的测试,但对于我的浏览器,这给了我:
"Mountain Daylight Time"
希望这有助于那里的人。
答案 12 :(得分:-1)
没有直接的方法,但你可以这样做:
var dd = new Date(); var d = dd.toString();
var startOff = d.indexOf('(')+ 1; var endOff = d.lastIndexOf(')');
var str = d.substring(startOff,endOff);
我创建了一个JS小提琴,您可以在其中看到警报: JSFiddle
var dd = new Date();
var d = dd.toString();
alert(d);
var startOff= d.indexOf('(') + 1;
alert(startOff);
var endOff= d.lastIndexOf(')');
alert(startOff+ " : " + endOff);
var str = d.substring(startOff , endOff);
alert(str);
