Question

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>
    </a>
    <p class="credits">Made by Jaiveer Chadda &nbsp; &nbsp; </p>

    <script type="text/javascript" src="script.js"></script>

  </body>


</html>

使用Javascript：

window.onload = function() {

function showDate() {

        var now = new Date();
        var date = ((now.getDate() < 10) ? "0" : "") + now.getDate();

      function fourdigits(number) {
          return (number < 1000) ? number + 1900 : number;
        }

        tnow = new Date();
        thour = now.getHours();
        tmin = now.getMinutes();
        tsec = now.getSeconds();

        if (tmin <= 9) { tmin = "0" + tmin; }
        if (thour < 10) { thour = "0" + thour; }

        if (thour > 12) {
          thour = thour - 12;
        }

        if (thour < 10){
          thour = "0"  + thour ;
        } else {
          thour = ""  + thour ;
        }

        if (tsec % 2 == 1){
          today = thour + " &nbsp "  + tmin;
        } else {
          today = thour + " : "  + tmin;
        }

        if (tsec < 10){
          now = "0"  + tsec ;
        } else {
          now = ""  + tsec ;
        }


        document.getElementById("timeDiv").innerHTML = today;
        document.getElementById("secondsDiv").innerHTML = now;


      }

      setInterval("showDate()", 1000);

当我将此代码作为本地文件运行时，它的所有工作都应该如此。时间和报价都有效，时间每秒都在刷新。

但是，当我将其设为本地镀铬扩展时，只有报价有效。

请帮助。

您违反了针对扩展程序强制执行的若干内容安全策略。

阅读the documentation。它非常全面。

您不能拥有内联代码：禁止在HTML中设置onload="..."。如果您确实需要绑定到load事件（在这种情况下非常有疑问），请使用addEventListener。考虑切换到DOMContentLoaded事件。
您的调用setInterval("showDate()", 1000);是一个隐式eval：您强制JavaScript引擎解析字符串以执行，而不是完全不必要地使用对函数的引用。这个很容易修复：setInterval(showDate, 1000);

当我将其添加到Chrome扩展程序时，此代码中的JavaScript无法正常工作
