onmouseover和onmouseout setInterval

Question

这个问题一直困扰着我。我使用滑块作为我的应用程序。对于滑动应用程序，我正在使用夹板-js。我的图像滑块很好用。

我已经将滑块与我的li元素连接起来。我想要定制onmouseover和onmouseout事件。当用户在mouseover上触发li时，它将暂停，当mouseout将恢复幻灯片时。

我正在检查这个堆叠溢出柱，并试图通过使用setinterval来像人一样执行逻辑，但无法做到。

​

const autoPlay = false;
const pauseOnHover = document.getElementById('pause');

function nextSlide() { //I don't what kind logic I should use to pause the slide

}

let  timer = setInterval(function() {
  nextSlide();
}, 400);


pauseOnHover.onmouseover = () => {
  if( autoPlay) {
    timer
  }
}
pauseOnHover.onmouseout = () => {
  if (autoPlay) {
    clearInterval(timer)
  }
}

<div class='checklist' id="pause">
  <ol>
    <li id="link-1">Assign jobs in an instant.</li>
    <li id="link-2">Always see what's happening.</li>
    <li id="link-3">Easy to set-up & use.</li>
    <li id="link-4">Be more sustainable</li>
  </ol>
</div>

Answer 1

请输入并恢复鼠标悬停时的间隔，如果存在间隔，请取消。

请试试下面的代码。

​

const autoPlay = false;
const pauseOnHover = document.getElementById('pause');

function nextSlide() {
  //For example I have put console.log, you mat put any code block here.
  console.log("hello");
}

let timer;


pauseOnHover.onmouseover = () => {

  autoplay = true;
  if (!autoPlay) {
    autoplay = true;
    timer = setInterval(function() {
      nextSlide();
    }, 400);
  }
}
pauseOnHover.onmouseout = () => {

  autoplay = false;
  timer && clearInterval(timer)

}

<div class='checklist' id="pause">
  <ol>
    <li id="link-1">Assign jobs in an instant.</li>
    <li id="link-2">Always see what's happening.</li>
    <li id="link-3">Easy to set-up & use.</li>
    <li id="link-4">Be more sustainable</li>
  </ol>
</div>
