我想在我的i18n-ed应用中显示7个工作日的列表:
Sunday, Monday, Tuesday... Saturday
我依靠Intl global object格式化日期/时间,但我找不到仅工作日名称的简单方法。
我想我可以在EPOCH时间增加一些时间,以达到一周的第一天,但是我没有在工作日找到格式化程序打印。
var date = new Date(0);
date.setDate(4 + day);
for (var i = 0; i < 7; i++) {
var weekday = new Intl.DateTimeFormat(["en"], {
weekday: "short" // ?? what should I put here
}).format(date);
console.log(weekday);
}
输出:
Sunday, January 4, 1970
Monday, January 5, 1970
Tuesday, January 6, 1970
Wednesday, January 7, 1970
Thursday, January 8, 1970
Friday, January 9, 1970
Saturday, January 10, 1970
期望的输出:
Sunday
Monday
Tuesday
Wednesday
Thursday
Friday
Saturday
我还希望有更短的版本,例如Sun, Mon, Tue...
。
或者,有没有办法从Intl
获取工作日字符串?我试图通过控制台探索对象,但我找不到它们。

我被误导了,因为我使用的是Intl polyfill,它不支持{ weekday: "short" }
作为选项。
使用本机Intl实现按预期工作。

const weekdayDateMap = {
Mon: new Date('2020-01-06'),
Tue: new Date('2020-01-07'),
Wed: new Date('2020-01-08'),
Thu: new Date('2020-01-09'),
Fri: new Date('2020-01-10'),
Sat: new Date('2020-01-11'),
Sun: new Date('2020-01-12'),
};
const shortWeekdays = Object.keys(weekdayDateMap);
const getDayOfWeek = (shortName, locale = 'en-US', length = 'short') =>
new Intl.DateTimeFormat(locale, { weekday: length }).format(weekdayDateMap[shortName]);
const getDaysOfWeek = (locale = 'en-US', length = 'short') =>
shortWeekdays.map(shortName => getDayOfWeek(shortName, locale, length));
用法:
getDayOfWeek('Mon', 'de-DE') -> "Mo"
getDaysOfWeek('de-DE') -> ["Mo", "Di", "Mi", "Do", "Fr", "Sa", "So"]
注意:
如果您每秒调用格式化程序很多次,那么一次创建格式化程序并重新使用它会更有效。

/**

function daysForLocale(localeName = 'es-MX', weekday = 'long') {
const format = new Intl.DateTimeFormat(localeName, { weekday }).format;
return [...Array(7).keys()]
.map((day) => format(new Date(Date.UTC(2021, 5, day))));

Intl
(ergo Intl.js
)也没有API来获取工作日名称,所以你必须做一些黑客的事情,用正确的方式查询一堆天选项。这可能是add support for doing so in the future,但现在你基本上没有运气了。 (至少,除非您手动使用修补程序增加Intl.js
。)

试试这个,拆分工作日字符串。
private void disableNic()
{
SelectQuery wmiQuery = new SelectQuery("SELECT * FROM Win32_NetworkAdapter WHERE NetConnectionId != NULL");
ManagementObjectSearcher searchProcedure = new ManagementObjectSearcher(wmiQuery);
foreach (ManagementObject item in searchProcedure.Get())
{
if (((string)item["NetConnectionId"]) == Interface.Name)
{
item.InvokeMethod("Disable", null);
}
}
}
void Disable(string interfaceName)
{
System.Diagnostics.ProcessStartInfo psi =
new System.Diagnostics.ProcessStartInfo("netsh", "interface set interface \"" + interfaceName + "\" disable");
System.Diagnostics.Process p = new System.Diagnostics.Process();
p.StartInfo = psi;
p.Start();
}
