由于没有正确链接，我似乎无法显示我的java脚本。
我真的不明白我的链接有什么问题。我试图建立一个有功能测验的网站，但自从java不会出现整个事情就变成了kaput。

改变这个：
<script type="text/javascript" src="/_assets/_js/quiz2.js"></script>
对此：
<script type="text/javascript" src="_assets/_js/quiz2.js"></script>
当您在开头添加/时，它将使用绝对路径而不是相对路径。鉴于您的CSS正在运行并且您正在使用该文件的相对路径，您应该也可以使用JS的相对路径。
答案 1 :(得分：0)
对于这个答案，我假设你_assets文件夹在你的HTML文件目录中。
更新脚本标记的来源。在开始源之前添加一个点（。）或从源中删除正斜杠（/）。以下是您的问题解决方案的两种可能性。
<强> SRC = “_资产/ _js / quiz2.js”
<强> SRC = “./_资产/ _js / quiz2.js”
答案 2 :(得分：0)
您的JavaScript中存在拼写错误：
function_(x) {
return document.getElementById(x);
}
删除function关键字后面的下划线。此功能还需要一个名称。我想这应该是＆＃34; getId＆＃34;功能。
还有许多其他错误，例如没有带有＆＃34;进展的元素＆＃34;或＆＃34;区域＆＃34; ID。检查浏览器控制台，它通常会告诉您代码何时出现类似问题。
我为您修正了错误：
1将这些添加到您的HTML
<div id="progress"></div>
<div id="area"></div>
2用这个替换你破碎的功能：
function getId (x) {
return document.getElementById(x);
}
3删除loadQuesion函数中的非法新行。所以改变这个
area.innerHTML = "<h2>" + "You got "+correct+" of "+questions.length+" questions
correct </h2>";
到此：
area.innerHTML = "<h2>" + "You got "+correct+" of "+questions.length+" questions correct </h2>";
