RE: next and previous buttons for slideshow

[Dave Francis]

currentSlide is a URL param - needed on first entry and passed in the hrefs
therafter. Here's a quick-and-dirty working demo. You'll need to call it
"t11.cfm" or change the href's.



<cfset totalSlides=10>

<cfset nextSlide = (currentSlide MOD totalSlides) + 1>
<cfset prevSlide = (currentSlide - 1) + (totalSlides * (currentSlide eq 1))>

<cfoutput>
        NEXT:#nextSlide#&nbsp;&nbsp;
        CURR:#currentSlide#&nbsp;&nbsp;
        PREV:#prevSlide#

<p style="margin-left:60px;"/>
        <a 
href="t11.cfm?currentSlide=#prevSlide#">&lt;PREV</a>&nbsp;&nbsp;&nbsp;
        <a href="t11.cfm?currentSlide=#nextSlide#">NEXT&gt;</a>
</cfoutput>

I've been following this thread because the method
of "next / previous" is better than what I currently use...so...

I was looking over the code below and I have a few questions...

How is the variable "currentSlide" being defined?  In assumed
previous code?

Also, would you put some hard numbers in there for me to view
how the functions are working?

TIA...

Rick

This should work:

        <cfset totalSlides=10>

        <cfset nextSlide = (currentSlide MOD totalSlides) + 1>
        <cfset prevSlide = (currentSlide - 1) + (totalSlides * (currentSlide eq
1))>
