与其复制我正在使用的所有代码，不如举个例子。我有：

<body onload="show()" >
//while show() is a : setInterval (function(){ thing=thing+1;},500);

然后在 HTML 中我有一个按钮：

<button  onclick="thingPlus100()">Upgrade</button>

而thingPlus100()例如： 

function thingPlus100() {
    thing= thing+100;
}

在循环之外。

这不起作用。那么在这种情况下，您如何制作一个按钮，当按下该按钮时，该按钮的总和为 100，而不会破坏循环？!!!扩展：这是html：

我想指出您的 JavaScript 代码并不是真正的 JavaScript。这是非常糟糕的代码（将这些变量包装在对象中，使用循环而不是 20 行选择器等）。首先清理它对你很有帮助。此外，setInterval调用它是一个相当有问题的函数，因为它必须手动取消。如果您在间隔上调用的代码中有错误，您将不断产生错误。相反，使用 setTimeout：

function X(...) {
  doThing();
  setTimeout(function() { X(...); }, 250);
}

现在，如果出现错误，它会发生一次，然后停止。您不再用错误淹没客户端。好的。

这不是您要寻找的答案，但确实是您在尝试找出问题之前应该做的事情。
