Hello everybody,
I am a complete Javascript novice but I'm hoping that you kind, intelligent, and beautiful people will find it in your hearts to help me. :thumbsup:
I'm pretty sure what I'm trying to do is very simple but I just can't get it working!
Found a nice bit of code for a content 'glider' I want to use...
var featuredcontentglider={
csszindex: 100,
ajaxloadingmsg: '<b>Fetching Content. Please wait...</b>',
glide:function(config, showpage, isprev){
var selected=parseInt(showpage)
if (selected>=config.$contentdivs.length){ //if no content exists at this index position
alert("No content exists at page "+(selected+1)+"! Loading 1st page instead.")
selected=0
}
var $target=config.$contentdivs.eq(selected)
//Test for toggler not being initialized yet, or user clicks on the currently selected page):
if (config.$togglerdiv.attr('lastselected')==null || parseInt(config.$togglerdiv.attr('lastselected'))!=selected){
var $selectedlink=config.$toc.eq(selected)
config.$next.attr('loadpage', (selected<config.$contentdivs.length-1)? selected+1+'pg' : 0+'pg')
config.$prev.attr('loadpage', (selected==0)? config.$contentdivs.length-1+'pg' : selected-1+'pg')
var startpoint=(isprev=="previous")? -config.startpoint : config.startpoint
$target.css(config.leftortop, startpoint).css("zIndex", this.csszindex++) //hide content so it's just out of view before animating it
var endpoint=(config.leftortop=="left")? {left:0} : {top:0} //animate it into view
$target.animate(endpoint, config.speed)
config.$toc.removeClass('selected')

It does exactly what I want EXCEPT I would like a nice fading effect (instead of gliding), just as per this code:
var fadecontentviewer={
csszindex: 100,
fade:function($allcontents, togglerid, selected, speed){
var selected=parseInt(selected)
var $togglerdiv=$("#"+togglerid)
var $target=$allcontents.eq(selected)
if ($target.length==0){ //if no content exists at this index position (ie: stemming from redundant pagination link)
alert("No content exists at page number "+selected+"!")
return
}
if ($togglerdiv.attr('lastselected')==null || parseInt($togglerdiv.attr('lastselected'))!=selected){
var $toc=$("#"+togglerid+" .toc")
var $selectedlink=$toc.eq(selected)
$("#"+togglerid+" .next").attr('nextpage', (selected<$allcontents.length-1)? selected+1+'pg' : 0+'pg')
$("#"+togglerid+" .prev").attr('previouspage', (selected==0)? $allcontents.length-1+'pg' : selected-1+'pg')
$target.css({zIndex: this.csszindex++, visibility: 'visible'})
$target.hide()
$target.fadeIn(speed)
$toc.removeClass('selected')
$selectedlink.addClass('selected')
$togglerdiv.attr('lastselected', selected+'pg')
}
},
setuptoggler:function($allcontents, togglerid, speed){
var $toc=$("#"+togglerid+" .toc")
$toc.each(function(index){
$(this).attr('pagenumber', index+'pg')
})
var $next=$("#"+togglerid+" .next")
var $prev=$("#"+togglerid+" .prev")
$next.click(function(){
fadecontentviewer.fade($allcontents, togglerid, $(this).attr('nextpage'), speed)
return false
})

return false
})
$toc.click(function(){

return false
})
},
init:function(fadeid, contentclass, togglerid, selected, speed){
$(document).ready(function(){
var faderheight=$("#"+fadeid).height()
var $fadecontents=$("#"+fadeid+" ."+contentclass)
$fadecontents.css({top: 0, left: 0, height: faderheight, visibility: 'hidden'})
fadecontentviewer.setuptoggler($fadecontents, togglerid, speed)

To my untrained eyes the codes seem very similar, both use jquery, and I have tried chopping and changing code, but I'm buggered if I can get it to work.
Any help would be massively appreciated, I wouldn't normally ask but it just seems like it should be really simple :confused:
Anyhoo, thanks in advance x
