When I run this code as a local file, all of it works like it should. 当我将此代码作为本地文件运行时，所有代码都应按应有的方式工作。 The time and quote are both working, and the time is refreshing every second. 时间和报价均正常工作，并且时间每秒刷新一次。
But when I make it a local chrome extension, only the quote is working. 但是当我将其设为本地chrome扩展名时，只有引号有效。
Pls help. 请帮助。

You are violating several Content Security Policies that are enforced for an extension. 您违反了为扩展实施的几个内容安全策略。
Have a read through the documentation . 通读文档 。 It's quite comprehensive. 非常全面。
You cannot have inline code: setting
onload="..."inside the HTML is forbidden.您不能有内联代码：禁止在HTML内设置onload="..."。 If you really need to bind toloadevents (which is extremely doubtuful in this case), useaddEventListener.如果您确实需要绑定到load事件（在这种情况下这是非常可疑的），请使用addEventListener。 Consider switching toDOMContentLoadedevent though.不过，请考虑切换到DOMContentLoaded事件。Your call
setInterval("showDate()", 1000);您的呼叫setInterval("showDate()", 1000);is an impliciteval: you force the JavaScript engine to parse the string to execute instead of using a reference to a function, completely needlessly.是一个隐式的eval：强制JavaScript引擎完全不必要地解析要执行的字符串，而不是使用对函数的引用。 This one is easy to fix:setInterval(showDate, 1000);这个很容易解决： setInterval(showDate, 1000);
