JavaScript document.write is not working
提问by Maria Ines Parnisari
Sorry if this seems dumb, i'm new to JavaScript.
对不起，如果这看起来很愚蠢，我是 JavaScript 的新手。
This is in menu.js:
这是在menu.js：
document.write("<a href="index.html">Home</a>");
document.write("<a href="news.html">News</a>");
document.write("<a href="about.html">About us</a>");
This is in index.html:
这是在index.html：
<head>
</head>
<body>
<script type="text/javascript" src="menu.js"></script>
</body>
</html>
When I load index.html, nothing comes up...
当我加载时index.html，什么也没有出现......

The problem is your quotes, you're using "both to delimit your new elements and to set their hrefattribute, change your code to:
问题是您的引号，您"同时使用它们来分隔新元素并设置它们的href属性，将代码更改为：
document.write("<a href='index.html'>Home</a>");
document.write("<a href='news.html'>News</a>");
document.write("<a href='about.html'>About us</a>");
Or:
或者：
document.write('<a href="index.html">Home</a>');
document.write('<a href="news.html">News</a>');
document.write('<a href="about.html">About us</a>');
Combining single (') and double (") quotes. You could also escape your internal quotes (document.write("<a href=\"index.html\">Home</a>");
结合单 ( ') 和双 ( ") 引号。您也可以转义内部引号 (document.write("<a href=\"index.html\">Home</a>");
BUT it'd be better to use a single call to document.write(), like this:
但是最好使用单个调用document.write()，如下所示：
document.write('<a href="index.html">Home</a>'
+ '<a href="news.html">News</a>'
+ '<a href="about.html">About us</a>');

You're not escaping the quotes in your strings. It should be:
您没有转义字符串中的引号。它应该是：
document.write("<a href=\"index.html\">Home</a>");
Otherwise, JavaScript thinks the string ends after href=and the rest of the line does not follow valid JavaScript syntax.
否则，JavaScript 认为字符串在此之后结束，href=并且该行的其余部分不遵循有效的 JavaScript 语法。
As @Felix mentioned, the JavaScript debugger tools will be extremely helpful in letting you know what's going on.
正如@Felix 所提到的，JavaScript 调试器工具将非常有助于让您了解正在发生的事情。
