Question

当用户单击按钮时，它将更改var速度值。我怎样才能做到这一点？目前，它设置为1000毫秒// 1秒，如下所示：

var increment = setInterval(increment,1000); // gain 1 ever second // THIS IS WHAT I WANT TO CHANGE

我想在点击按钮时将1000更改为2000。我认为它叫增量值？我只知道它在1000毫秒的时间内设置它以获得数字的速度。

Answer 1

我将其更改为使用setTimeout。所以：

var increment = setInterval(increment,1000); // gain 1 ever second // THIS IS WHAT I WANT TO CHANGE
function increment(){
    Coal = Coal % 99999999999999999999 + CoalRate;
    totalCoal = totalCoal % 99999999999999999999 + CoalRate;
    document.getElementById("Coalcounter").innerHTML="Coal : " + Math.round(Coal);
    document.getElementById("CoalClickercost").innerHTML="Upgrade Coal Clicker : " + Math.round(CoalClickerPrice);
    document.getElementById("CoalRatecost").innerHTML="Upgrade Coal Rate : " + Math.round(CoalRatePrice);
}

会变成：

var interval = 1000
function increment(){
    Coal = Coal % 99999999999999999999 + CoalRate;
    totalCoal = totalCoal % 99999999999999999999 + CoalRate;
    document.getElementById("Coalcounter").innerHTML="Coal : " + Math.round(Coal);
    document.getElementById("CoalClickercost").innerHTML="Upgrade Coal Clicker : " + Math.round(CoalClickerPrice);
    document.getElementById("CoalRatecost").innerHTML="Upgrade Coal Rate : " + Math.round(CoalRatePrice);
    window.setTimeout(interval)
}
increment()

然后你的onclick变得像......一样简单。

<button onclick="swapInterval">Swap</button>

和

function swapInterval() {
    if(interval==1000) interval = 2000
    else interval = 1000
}

请注意，这不会改变当前循环（例如，如果你在2000年，你在500毫秒后按下按钮，你仍然需要等待另一个1500毫秒才能触发）。

Answer 2

您可以清除间隔并再次创建

$('#element').click(function(){
     window.clearInterval(incrementID); //
     timing = timing + 1000; //this is if you plan to keep adding up.
     incrementID = setInterval(increment, timing);// if not you can always hardcode 2000
});

也：

var timing = 1000;
var incrementID = setInterval(increment,timing); // gain 1 ever second // THIS IS WHAT I WANT TO CHANGE
//you should change the varname so that you can use the handle to clear the already set interval

更改var的速度值onClick？
