javascript - Whack-A-Mole JavaScript返回和循环不起作用

转载作者：行者123 更新时间：2023-11-28 02:04:59

我一直在尝试编码Wack-A-Mole，但是有一些问题。我目前有两个return语句，但是当我将stopper3和stopper4设置为true并在Trigger中重新运行该函数时。这是行不通的。另外，我编写了diwn两个函数来重复检查stopper1和stopper2是否为true，然后再次运行，但我不知道如何循环使用它们。我不希望有一天，setTimeout无法正常工作，并且我不了解回调。

我要问的是，如何循环2个Cycle函数，以及为什么在函数的停止器再次设置为true之后，return语句不会取消返回。

最佳答案

回油塞

我不清楚返回值，但是有没有缘由从未将stopper4设置为true？您将stopper4设置为false两次或三次，但从未设置为true。

循环功能

这是循环两个循环功能的方式：

  (function Cycle1() {
    if (stopper1) {
      setTimeout(Trigger, 1000);
    }
  })();

请注意此语法与您所拥有的语法之间的区别。此语法将立即执行该功能。该模式如下所示：

(function(){

})();

（请注意，您甚至可以根据需要删除函数名称-代码中未使用或不需要它们）

您可以研究立即调用函数表达式（IIFE）。请在此处找到一个代码笔： https://codepen.io/anon/pen/ZrZBLx

您可能会发现这并不能解决所有问题，但是您非常非常亲密。做得好！
