.next is undefined, jquery plugin problem
- by ndelangen
I'm trying to create my own plugin. But I'm having trouble getting things right.
It appears when I'm trying to traverse inside .each things go wrong.
I'm trying to go to the next item every 6 seconds by fading.
jQuery(function($){
$.fn.rotator = function(options){
this.each(function() {
var container = $(this);
var images = container.children();
//Set the opacity of all images to 0
images.css({opacity: 0.0});
//Get the first image and display it (gets set to full opacity)
$('div:first',this).css({opacity: 1.0}).addClass('show');
//Call the rotator function to run the slideshow, 6000 = change to next image after 6 seconds
var obj = $(this);
setInterval(nextimage(obj),6000);
});
};
// rotate function
function nextimage(obj) {
var container = $(obj);
var images = container.children();
//Get the current image
var current = (images.hasClass('show')? images.hasClass('show') : images.first());
//Get next image, when it reaches the end, rotate it back to the first image
var next = ((current.next().length) ? ((current.next().hasClass('show')) ? images.first() :current.next()) : images.first());
//Set the fade in effect for the next image, the show class has higher z-index
next.css({opacity: 0.0})
.addClass('show')
.animate({opacity: 1.0}, 1000);
//Hide the current image
current.animate({opacity: 0.0}, 1000)
.removeClass('show');
};
});
$(document).ready(function(){
$("#bg").rotator({
})
});
The error I get is:
current.next is not a function
Line 35
Line 35 =
var next = ((current.next().length) ? ((current.next().hasClass('show')) ? images.first() :current.next()) : images.first());
Can someone tell me what I'm doing wrong?
