javascript - jQuery Circular Content Carousel Autoscroll - Stack Overflow

programmeradmin5浏览0评论

I found a cool carousel script named Circular Content Carousel by Tympanus. It's almost exactly what I need. When clicking on the "more" link, the respective item moves to the left and a content area will slide out.

What I need to achieve now is to make it autoscroll and stopped while mouseover on the carousel and when the content area opened.

I'm a newbie in javascript & jquery, so I desperately need an expert help. Can somebody help me customize this carousel?

Here's a link of the working Circular Content Carousel. /

Thanks in advanced.

Reset to default 10

here is an update:

Not the best way, but is going to work

Update:

http://jsfiddle/x7jxa/4/

Yes, i agree with function, but Fiddle for some reason return an weird error.

<script type="text/javascript">
  $('#ca-container').contentcarousel();
  var int = setInterval("$('.ca-nav-next').trigger('click');",1000);                          
  $('.ca-item').hover(function(){
    clearInterval(int);
  },function(){
    int = setInterval("$('.ca-nav-next').trigger('click');",1000);    
  });
  $('.ca-nav').hover(function(){
    clearInterval(int);
  },function(){
    int = setInterval("$('.ca-nav-next').trigger('click');",1000);    
  });
</script>

I have had the same problem. I have just finished modifying the script a bit to allow for it. It is relatively stable and you can change the variables in the script. Its not pretty, but it works, modifications to clean it up wele. jquery.contentcarousel.js

(function($) {
var aux     = {
