从这段代码的JavaScript不像预期的那样工作，当我把它变成一个Chrome扩展

The JavaScript from this code is not working as expected when I made it into a Chrome Extension

本文关键字：一个 扩展 Chrome 代码 JavaScript 段代码 工作      更新时间：2023-09-26

这是代码:

HTML: 

<!DOCTYPE html>
<html>
  <head>
    <link rel="stylesheet" type="text/css" href="stylesheet.css">
    <title>New Tab</title>
  </head>
  <body id="body" onload="showDate()">
    <div id="timeDiv"> &nbsp; &nbsp; &nbsp; </div>
    <div id="secondsDiv"> &nbsp; &nbsp; </div>
    <div id="quoteDiv" onload="randomQuote()"> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</div>
    <a href="intro.html">
      <div class="element"></div>
      <p class="logo">a</p>

      }
      setInterval("showDate()", 1000);

当我将这段代码作为本地文件运行时，它的所有工作都像它应该的那样。时间和报价都在工作，时间每秒钟都在刷新。

但是当我使它成为一个本地chrome扩展，只有报价是工作的。

请帮助。

您违反了对扩展强制执行的几项内容安全策略。

通读文档。

  • 不能使用内联代码:禁止在HTML中设置onload="..."。如果您确实需要绑定到load事件(在这种情况下这是非常值得怀疑的)，请使用addEventListener。考虑切换到DOMContentLoaded事件。

  • 你的setInterval("showDate()", 1000);调用是一个隐式的eval:你强迫JavaScript引擎解析字符串来执行，而不是使用一个函数的引用，完全没有必要。这个很容易修复:setInterval(showDate, 1000);
