我已经在我的网站上添加了一些JavaScript，当你移动它时，它会在鼠标后面添加一个闪光效果，我非常喜欢它。除了页面大约一半的事实外，还会出现一个随机的新滚动条，它会滚过页脚并永远滚动。我似乎无法弄清楚要添加什么，或者让它停止滚过页脚。我已经尝试为身体/ html设置最大高度......我已经尝试取出＆＃34;设置滚动＆＃34;功能，我需要它永远停止滚动。我也试过添加finish（）方法，但我不确定它到底在哪里。这是我的代码。

这是错误定位的闪光点。如果您看一下检查员（F12，您会看到它们的动画效果）。计算出来的位置已被修正，因为它们是直接在体内创造的，它们会使它生长，并且生长...
由于整个脚本都是黑客攻击，你可以通过身体上的max-height属性进一步破解它...
没有火花很好但是你应该寻找替代品，这件JS很糟糕。并且这里没有涉及jquery，它只是跟随鼠标的div。你应该寻找一个合适的插件。
