Node.js EJS模板：如何从href中删除端口号？

Question

I have the below code. I would like to print out the file names in that directory and append an href tag. The below code works but only the port number my node.js app is listening to is still there. How could I remove that (so my hrefs will actually work?). Something with the document object, as in truncating the URL?

<h1><%= title %></h1>
<p>Welcome to
    <%=t itle %>
</p>
<ul>
    <% for(var i=0; i<fs.readdirSync( './Week4/').length; i++) {%>
        <li>
            <a href="<%= fs.readdirSync('./Week4/')[i] %>">
                <%=f s.readdirSync( './Week4/')[i] %>
            </a>
        </li>
        <% } %>
</ul>

From reading your comments, it seems that your problem is not where you think it is. The :8080 you see is written automatically because you specify an href that is relative to the current URL:

If the current URL is localhost:8080/Week4/index.html , going to the relative URL itemlist will in fact redirect you to localhost:8080/Week4/itemlist .

If this is not the way you intend things to work, you have to specify an absolute URL. For instance, using //localhost:80/Week4/itemlist will redirect you to another server (or another listener on the same server).

I don't exactly know what you are trying to achieve but, to me, the behavior you are expecting doesn't sound really good. A link should not redirect to a different port on the same server except if you are doing something very specific.

If you could tell us what you are really trying to achieve, we could help you better.
