[jQuery] Next and Previous Slide Button Functionality i++, i--

Question

Hi Ya'll,

I had a great experience asking a question last time and thought I'd come back for more help. You guys are wonderful. Thank you in advance.

I am working with a featured post slider that advances through 4 posts automatically. I would like to add next and previous buttons. I know that I need to attach some kind of .click() event to #movers-next and #movers-previous but everything I've tried so far has resulted in spotty performance.

Can you please help me code a stable method of looping through variable 'curclicked'? (NOTE: .stripNav ul li a is auto-generated by the plugin as a means of looping through posts)

Thank You.

<script type="text/javascript">
var theInt = null;
var $crosslink, $navthumb;
var curclicked = 0;

theInterval = function(cur){
 clearInterval(theInt);

 if( typeof cur != 'undefined' )
  curclicked = cur;

 $crosslink.removeClass("active-thumb");
 $navthumb.eq(curclicked).parent().addClass("active-thumb");
  jQuery(".stripNav ul li a").eq(curclicked).trigger('click');

 theInt = setInterval(function(){
  $crosslink.removeClass("active-thumb");
  $navthumb.eq(curclicked).parent().addClass("active-thumb");
  jQuery(".stripNav ul li a").eq(curclicked).trigger('click');
  curclicked++;
  if( 6 == curclicked )
   curclicked = 0;

 }, 8000);
};



jQuery(function(){

 jQuery("#main-photo-slider").codaSlider();

 $navthumb = jQuery(".nav-thumb");
 $crosslink = jQuery(".cross-link");

 $navthumb
 .click(function() {
  var $this = jQuery(this);
  theInterval($this.parent().attr('href').slice(1) - 1);
  return false;
 });

 theInterval();
});
