Question

我为每个用户保存了时区，以及＃34;欧洲/布加勒斯特＆＃34;或＆＃34;欧洲/纽约＆＃34;。

然而，角度只接受时区偏移字符串：＆＃34; + 0400＆＃34;或＆＃34; -0330＆＃34;将值作为过滤器传递给日期时。

如何将这些字符串转换为时区偏移字符串？

假设您已安装moment-timezone库：

(function ()
{
    var app = angular.module("app", []);

    function HomeController()
    {
        var vm = this;
        vm.europe = moment().tz('Europe/Bucharest').format("ZZ");
        vm.us = moment().tz('America/New_York').format("ZZ");
    }

    app.controller("HomeController", [HomeController]);
})();
