引号的颜色或内容未显示

Question

我写了两个随机改变背景颜色和引号内容的函数。接下来，我制作了一个按钮，在单击时执行这些功能。我成功地改变了颜色，但引号不会出现，当这两个功能都在程序上时，颜色也不会改变。我的代码有什么问题？

Answer 1

您在第 46 行缺少一个逗号。这在开发人员工具的浏览器控制台中显示为错误。

Uncaught SyntaxError: Unexpected string

只需在该行末尾添加一个逗号：

"We are what we repeatedly do. excellence, then, is not an act but a habit.—Aristotle",
