私は最終的にはフリルのない素晴らしいJavaScriptカウントアップタイマーを見つけました。私はカウントアップするために異なる初期時間を持つタイマーの複数のインスタンスを開始したいと思います。これまでの唯一の進歩は、スクリプトを壊すことです。ボタンのために、このHTMLをJavaScriptのカウントアップタイマーの変更
var counterNum = 1;
function addCounter() {
var div = document.createElement("div");
div.id = "counter" + counterNum++;
document.body.appendChild(div);
var x = new CountUp(new Date(), div.id);
}
