Commenting code in ASP Classic

问题

The way I know of hashing out code within ASP Classic is <%-- --%>. Would this be correct? Or is there another way?

回答1:

Use a single quote, like:

' This is comment

ASP Classic uses the VBScript/Visual Basic language, and a single quote is commenting in that; <%-- is nothing (I am not 100% sure though).

回答2:

Beside ', you can comment lines in the old school way:

 REM Response.Write "Ignore this line"

Which is same with

 ' Response.Write "Ignore this line"

Assuming you mean that you have large block of inline code like the below you want to disable:

<%
    CallSomething()
    DoSomething()
    Response.Write("all done")
%>

Then either comment out each line as described in this other answer or other approach is:

1. Create a dummy, empty file called "dummy.asp" and place it in the same folder.

2. Change the code block to this:

   <script language="vbscript" runat="server" src="dummy.asp">
       CallSomething()
       DoSomething()
       Response.Write("all done")
   </script>
   

   Note: you need to change only the <% and %>, all other lines can stay intact. Having a src in the script tag will cause the Classic ASP engine to take the file contents instead of taking the script block contents.

Then when you want to uncomment, either do it for each line or put back the <% and %>.

The question says... ASP classic.....

All the above answers are good, but specific to VBScript.

But a classic ASP file can also contain HTML and Javascript

This is the best way to comment out large blocks of code:

<%if 1=2 then%>

html or other code here

<%end if%>
