Re: scroll with delay and loop list item

I'd like to automatically loop my code and I'd like to change without button.

$(function() {
$.fn.scrollTo = function( target, options, callback ){
if(typeof options == 'function' && arguments.length == 2){ callback = options; options = target; }
var settings = $.extend({
scrollTarget : target,
offsetTop : 50,
duration : 500,
easing : 'swing'
}, options);
return this.each(function(){
var scrollPane = $(this);
var scrollTarget = (typeof settings.scrollTarget == "number") ? settings.scrollTarget : $(settings.scrollTarget);
var scrollY = (typeof scrollTarget == "number") ? scrollTarget : scrollTarget.offset().top + scrollPane.scrollTop() - settings.offsetTop;
scrollPane.animate({scrollTop : scrollY }, settings.duration, settings.easing, function(){
if (typeof callback == 'function') { callback.call(this); }
});
});
}
var $chapters = $('#demo-stage').find('ul').children('li');
var $chScrollPositions = new Array();
$chapters.each(function(i){
$chScrollPositions[i] = Math.round($(this).offset().top - $('#demo-stage').offset().top) - 10;
});
$chapters.eq(0).addClass('active'); // Set First Chapter Active on Start
$('#demo-nav > nav > button').click(function(){
var last = $chapters.parent().find('li.active').removeClass('active').index();
var next;
switch($(this).index()){
case 1: // Action - Next Chapter
next = (last + 1 == $chapters.length) ? 0 : last + 1; // Loop around to first chapter
break;
case 2: // Action - Last Chapter
next = $chapters.length - 1;
break;
case 3: // Action - First Chapter
next = 0;
break;
}
$chapters.eq(next).addClass('active'); // Set Next Chapter Active
$('#demo-stage').scrollTo($chScrollPositions[next]);
});
});

It would really be helpful to see this live. With the CSS and the HTML.

Or do you just want to programatically just keep clicking rthe same button?

That’s just

setTimeout(function() {
$('#demo-nav > nav > button').click()
},10000)

Re: scroll with delay and loop list item

I would like to make some code for my "Item List" <ul> > <li>(* 3 or more ) with role (scroll) animate.

I would like to make my "item list" first child show at the start page after each 2 sec scrolled my next "item list" 2, 3 or more looping.

I still suffer from it. Because I started use jQuery 2 day ago.

Please help me. Also sorry my English.

If you help me I will be very happy.

Thanks

Do you want HTML Marquee Code ?

I need to know what your page looks like. I can’t guess anymore.
