js关闭页面清除定时器

在JavaScript中，关闭页面时清除定时器有几种方法。一种方法是在页面关闭事件中清除定时器。你可以使用window.onbeforeunload事件来监听页面关闭事件，然后清除定时器。具体的代码示例如下：

window.onbeforeunload = function() {
  clearInterval(a); // 清除定时器a
  for(var each in pageTimer) {
    clearInterval(pageTimer<span class="em">1</span><span class="em">2</span><span class="em">3</span>
