Question

我有以下网站：

＆＃13;

window.onload = function() {
  var executed = false;
  if (!executed) {
    document.getElementById("at").style.visibility = "visible";
    setInterval(function() {
      document.getElementById("t-ground").style.visibility = "visible";
      document.getElementById("ground").style.opacity = "0.3";
      setInterval(function() {
        document.getElementById("right-top").style.visibility = "visible";
        document.getElementById("t-ground").style.visibility = "hidden";
        document.getElementById("ground").style.opacity = "1.0";
        document.getElementById("t-plant").style.visibility = "visible";
        document.getElementById("hand").style.opacity = "0.3";
        setInterval(function() {
          document.getElementById("right-bot").style.visibility = "visible";
          document.getElementById("hand").style.opacity = "1.0";
          document.getElementById("t-plant").style.visibility = "hidden";
          document.getElementById("ab").style.visibility = "visible";
          document.getElementById("t-animal").style.visibility = "visible";
          document.getElementById("animal").style.opacity = "0.3";
          setInterval(function() {
            document.getElementById("left-bot").style.visibility = "visible";
            document.getElementById("animal").style.opacity = "1.0";
            document.getElementById("t-animal").style.visibility = "hidden";
            document.getElementById("t-human").style.visibility = "visible";
            document.getElementById("human").style.opacity = "0.3";

                document.getElementById("left-bot").style.visibility = "hidden";
                document.getElementById("left-top").style.visibility = "hidden";
                executed = true;
              }, 1725);

由于某些原因，加载网站后，隐藏和可见属性会一直发生变化。为什么会这样？

Answer 1

setInterval将每x ms重复执行一次该函数。因此，您的所有功能都会在可见和隐藏之间重复触发。

一旦你需要使用setTimeout，你只想在x ms之后触发一次。
