How to comment ejs code ( JS node)
提问by Toumi
I have this code in an ejs File.
我在 ejs 文件中有此代码。
<table>
<% for(var i=0; i < data.length; i++) { %>
<tr>
<td><%= data[i].id %></td>
<td><%= data[i].name %></td>
</tr>
<% } %>
</table>
When I comment it this way,
当我这样评论时，
<!-- <table> -->
<!-- <% for(var i=0; i < data.length; i++) { %> -->
<!-- <tr> -->
<!-- <td><%= data[i].id %></td> -->
<!-- <td><%= data[i].name %></td> -->
<!-- </tr> -->
<!-- <% } %> -->
<!-- </table> -->
I still have an error in Line 2. Here is the stack of the ERROR
我在第2行仍然有错误。这是错误的堆栈
ReferenceError: c:\Users\toumi\Desktop\workspaces\eclipse\ToDoList\views\x.ejs:2

回答by Artem Solovev
There is two solutions:
有两种解决方案：
<%# comment %>( it's from documentation)<%/* comment */%>( it works too but it's pretty ugly and uncomfortable for use )
<%# comment %>（它来自文档）<%/* comment */%>（它也有效，但使用起来非常丑陋且不舒服）
I don't see difference between those examples except highlighting syntax in IDE ( example with Brackets IDE )
除了在 IDE 中突出显示语法（Brackets IDE 示例）之外，我没有看到这些示例之间的区别

Sample of the <% /* */ %>format for multi-line.
<% /* */ %>多行格式示例。
<% /* %>
<div>
<span>This will not be rendered</span>
<% for(var i=0; i < data.length; i++) { %>
<span>These won't be rendered either.</span>
<% } %>
</div>
<% */ %>

I found this helpful for me. It's simple, multiline and does not conflict with anything.
我发现这对我很有帮助。它很简单，多行并且不与任何东西冲突。
<%if(false) {%>
<ul>
<% for(var i =1; i <= 10; i++) { %>
<li>
Hello this is iteraiton <%=i %>
</li>
<% }%>
</ul>
<%- include('./meow') %>
<%} %>

This is ugly but it works:
这很丑陋，但它有效：
<%if (false) {%>
<div>
<span>This will not be rendered</span>
</div>
<%}%>

Two ways you can do!
两种方法你可以做到！
As mentioned in the Documentation of EJS.
如 EJS 文档中所述。
<%# commented out code %>
<%# 注释掉的代码 %>
<%/* multiple lines commented out code*/%>
<%/* 多行注释掉代码*/%>
eg:
例如：
<%# include('includes/head.ejs') %>
</head>
<body>
<%# include('includes/navigation.ejs') %>
<h1>Page Not Found!</h1>
<%- include('includes/end.ejs') %>
