我有javascript倒计时
var timersCount = 0;
var timerCounter = setInterval(countTimers, 30000);
countTimers();
function countTimers()
{
timersCount++;
var count = 26;
var counter = setInterval(timer, 1000);
function timer()
{
count = count-1;
if(count < 0) {
clearInterval(counter);
return;
}
document.getElementById("timer").innerHTML=count;
}
document.getElementById("countTimers").innerHTML=timersCount;
}
HTML
<button id="pause">Pause</button>
<button id="resue">Resume</button>
该功能正常运行。但现在我想添加Pause并恢复倒计时。是否可以将其设置为我的功能。请帮忙。

你走了。首先,你只需要一个间隔,第二个你应该有一些标志告诉你何时暂停计时器。然后它只是简单的逻辑和2个听众。
var timersCount = 0;
var pause = false; //is timer paused
countTimers();
function countTimers() {
timersCount++;
var count = 26;
var counter = setInterval(timer, 1000);
function timer() {
if (!pause) { //do something if not paused
count = count - 1;
if (count < 0) {
clearInterval(counter);
setTimeout(countTimers, 5000); //start count from 26 again
return;
}
document.getElementById("timer").innerHTML = count;
}
}
document.getElementById("countTimers").innerHTML = timersCount;
}
document.getElementById('pause').addEventListener('click', function () {
pause = true;
});
document.getElementById('resume').addEventListener('click', function () {
pause = false;
});

<span id="timer"></span>
<span id="countTimers"></span>
<button id="pause">Pause</button>
<button id="resume">Resume</button>
