Javascript计数计时器修改

javascript date timer

Javascript计数计时器修改,javascript,date,timer,counter,Javascript,Date,Timer,Counter,我终于找到了一个不错的javascript计数计时器，没有任何装饰。我想启动计时器的多个实例，从不同的初始时间开始计数。到目前为止，我唯一的进步就是打破了剧本 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang

此DIV的内容将被计时器替换

每次按下按钮时，此代码将向HTML添加一个新计数器：

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);
}

使用此HTML作为按钮：

<button onclick="addCounter()">Add Counter</button>

您可以使用此代码在10分钟内按下按钮开始添加计时器。

如果您愿意，也可以使用多个计数器预先填充页面。CountUp函数接受一个日期对象参数，该参数表示它的计数截止日期<代码>新日期（）将始终返回当前时间。在下面的示例中，我刚刚创建了几个

元素，并实例化了几个具有不同日期的

CountUp

函数。我所做的更改在底部
