我正在尝试使用 Countdown.js 。我发现this guide并复制代码并粘贴它以尝试调整和理解代码，但是当我在 my web 中运行它时我无法让它工作，在控制台中我得到“Uncaught ReferenceError:倒计时未定义(匿名函数)@ countdown..html:46”。

var timer = document.getElementById("logout-timer")
, now = new Date()
, deadline = new Date(now.getFullYear, now.getMonth, now.getDate, now.getHours, now.getMinutes + 15);
timer.innerHTML = countdown(deadline).toString();
setInterval(function(){
timer.innerHTML = countdown(deadline ).toString();

最佳答案
指南使用countdown中的示例实际上应该是Countdown。
// Declare the countdown object
// Constructor. target_date and current_date are Javascript Date objects
function Countdown(target_date, current_date) {
this.target_date = target_date;
this.current_date = current_date;
}
