如果页面是默认那么包括如果没有则默认 [英] if page is default then include if not default then
问题描述
我读过类似的问题,但没有一个似乎为我工作。
我有一个asp网站,我认为经典的(甚至不知道经典和净之差),与所有扩展名为ASP几页,和一些HTML包括,这些是一个滑块的一方,我只想展示当网页(Default.asp的),如果不是默认,然后一个div添加到标记。
我知道下面是错误的,但只是为了更好地解释我的需要。
<%
如果页面==的Default.asp
包括文件=slider.html
如果页面!=的Default.asp
< DIV CLASS =间隔顶>< / DIV>
%GT;
像许多在ASP-经典地在你的predecessors,什么你想是有条件的包含,而你碰到的问题是即传统的ASP没有做条件包括。 (之所以是,的#include
指令在页面上的任何脚本解析之前长柄)。
有涉及执行
或各种解决方法等危险,在最错手命令;搜索 ASP条件包括,你会发现更多的比你讨价还价对于。然而,在你的情况,它可能是简单包住的,你可以通过电话或不是一个子程序滑块显示。
Slider.html:
<%
子DisplaySlider()
code,显示滑块(可能是JavaScript的,我猜?)
%GT;
<脚本...>
< / SCRIPT>
<%
结束小组
%GT;
其他网页:
<! - #包括虚拟=/ slider.html - >
<%
脚本名称= Request.ServerVariables(SCRIPT_NAME)
如果INSTR(脚本名称的default.asp)> 0,则
DisplaySlider
其他
的Response.Write< DIV CLASS ='间隔顶'>< / DIV>中
万一

I've read similar questions, but none seems working for me.
I have an asp site, i think classic (don't even know difference between classic and net), with few pages all with asp extension, and some html includes, one of these being a slider which I want to only display when in homepage (default.asp), and if not default then add a div to the markup.
I know the following is wrong, but just to better explain my need.
<%
if page == default.asp
include file="slider.html"
if page != default.asp
<div class="spacer-top"></div>
%>
Like many of your predecessors in ASP-classic-land, what you're wanting is conditional includes, and the problem you're bumping into is that classic ASP doesn't do conditional includes. (The reason why is that the #include
directive is handled long before any script on the page is parsed.)
There are various workarounds involving Execute
or other dangerous-in-the-wrong-hands commands; search for "asp conditional include" and you'll find more than you were bargaining for. However, in your case, it might be simpler to encase the slider display in a subroutine that you can call or not.
Slider.html:
<%
Sub DisplaySlider()
'code to display the slider (probably JavaScript, I'm guessing?)
%>
<script ...>
</script>
<%
End Sub
%>
Other pages:
<!-- #include virtual="/slider.html" -->
<%
scriptname = Request.ServerVariables("Script_Name")
If InStr(scriptname, "default.asp") > 0 Then
DisplaySlider
Else
Response.Write "<div class='spacer-top'></div>"
End If
%>
