无论如何有一个for循环等到一个间隔被清除

Is there anyway of having a for loop wait until an interval have cleared

我有一个 for 循环 运行ning again 一个节点列表。我正在尝试 运行 通过节点列表并触发点击,然后我设置一个时间间隔来等待弹出窗口,然后我想在弹出窗口中触发点击。

我的问题是每次迭代都需要等到弹出窗口加载完毕并且弹出窗口中的项目被单击后才能进入下一次迭代。希望这是有道理的。

这是我的代码。

let checkSteats = () => {
  const seats = document.querySelectorAll(seatSectionSelector);
  if (seats.length < maxSeatCount) {
    maxSeatCount = seats.length;
  }

  if (seats.length > 0) {

    [].forEach.call(seats, (seat, index) => {
  /**
   * WE NEED TO CLICK WAIT FOR A CHANGE IN THE RESPONSE OR POP UP BEFORE WE GO INTO THE NEXT ITERATION
   */
  console.log(seat)
  if ((index+1) <= maxSeatCount) {

    seat.dispatchEvent(
      new MouseEvent('click', {
        view: window,
        bubbles: true,
        cancelable: true,
        buttons: 1
      })
    );

    const popupInterval = setInterval(() => {
      const popupBtn = document.querySelector('.ticket-option__btn');

      if (popupBtn) {
        popupBtn.click();
        clearInterval(popupInterval);
      }
    }, 100)


  } 
}); 

} 
};

您想使用一个基本队列,在该队列中使用 shift()

从数组的前面拉出项目

var myArray = [1, 2, 3, 4]

function nextItem() {
  var item = myArray.shift();
  window.setTimeout(function() {
    console.log(item);
    if (myArray.length) nextItem();
  }, 1000)
}
nextItem()

所以在你的情况下,你会在清除间隔时调用 nextItem() 。您可以通过将 html 集合转换为数组

来实现转变
const seats = Array.from(document.querySelectorAll(seatSectionSelector));
function nextItem() {
  var seat = seats.shift();
  seat.dispatchEvent(...);
  const popupInterval = setInterval(() => {
    ...
    if (popupBtn) {
      ...
      if (seats.length) nextItem();
    }
