javascript - 时刻未捕获类型错误 : Cannot read property 'format' of undefined at time

Question

这行代码我有这个错误

var FullDate = moment(1499153561479).add(currentSeconds, 'seconds').tz(citiesT[id]).format("DD-MM-YYYY HH:mm:ss a");

我该如何解决？

Answer 1

你需要包含moment-timezone库，CDN是http://cdnjs.cloudflare.com/ajax/libs/moment-timezone/0.4.1/moment-timezone- with-data-2010-2020.min.js和moment.min.js库，CDN是https://cdnjs.cloudflare.com/ajax/libs/moment .js/2.10.6/moment.min.js

然后当你定义了所有变量时你的代码就会工作

currentSeconds = 10000;
var citiesT = ["America/Los_Angeles"];
var id= 0;
var FullDate = moment(1499153561479).add(currentSeconds, 'seconds').tz(citiesT[id]).format("DD-MM-YYYY HH:mm:ss a");
alert(FullDate);
