Auto-scrolling in jQuery.scrollTo / jQuery.serialScroll works like crazy
I used the following tutorial to make a parallax content slider for my webiste: http://blog.themeforest.net/tutorials/create-a-funky-parallax-background-effect-using-jquery/
I got it working nicely, but wanted to add auto-scrolling functionality. I did it by adding jQuery.serialScroll and using setInterval but it works like crazy now. I guess the slide开发者_如何学Gor is now going through every 3 slides every 5 seconds, instead of 1 slide per 5 second. I have no idea how to make it working properly.
Here is a part of my HTML:
<body>
<div id="header">
<h1 id="logo">Testing slider</h1>
</div>
<!-- end logo -->
<div id="slider">
<div id="background">
<div id="bg">
</div>
</div>
<!-- end slide background -->
<div id="wrapper">
<ul id="mask">
<li id="box1" class="box">
<a name="box1"><img src="images/slide1.png"></a>
<div class="content">
<div class="inner">
</div>
</div>
</li>
<!-- end box1 -->
<li id="box2" class="box">
<a name="box2"><img src="images/slide2.png"></a>
<div class="content">
<div class="inner">
</div>
</div>
</li>
<!-- end box2 -->
<li id="box3" class="box">
<a name="box3"><img src="images/slide3.png"></a>
<div class="content">
<div class="inner">
</div>
</div>
</li>
<!-- end box3 -->
</ul>
<!-- end mask -->
</div>
<!-- end wrapper -->
</div>
<!-- end Slider -->
<div id="content">
<div id="menu">
<ul id="menuitem">
<li><a href="#box1" class="slide_next"></a></li>
<li><a href="#box2" class="slide_next"></a></li>
<li><a href="#box3" class="slide_next"></a></li>
</ul>
</div>
<!-- end menu -->
</div>
<!-- end content -->
And here is the troubling JS code:
<script type="text/javascript">
$(document).ready(function() {
$('a.slide_next').click(function () {
$('#wrapper').scrollTo($(this).attr('href'), 800);
setPosition($(this).attr('href'), '#background', '0px', '50px', '100px')
$('a.slide_next').removeClass('selected');
$(this).addClass('selected');
return false;
});
});
setInterval(function() {$('a.slide_next').click()}, 5000);
function setPosition(check, div, p1, p2, p3) {
if(check==='#box1')
{ $(div).scrollTo(p1, 800); }
else if(check==='#box2')
{ $(div).scrollTo(p2, 800); }
else
{ $(div).scrollTo(p3, 800); }
};
</script>
Please, anyone has any idea how to get it working the way it should be (1 slide each 5 sec)?
PS. Please be nice, I'm new in the field ;)
I think your problem is that you're triggering the click event on ALL 3 of your "slide next" links every 5 seconds, so it's going wappy trying to carry out your onclick code for each slide.
What you could do is something like this:
//set a global var to keep track of the slide we're on
window.slide = 1
function nextSlide(){
//increase window.slide by 1 (to go to the next slide),
//or if it is 3 return to the first slide
window.slide == 3 ? window.slide = 1 : window.slide++;
//trigger click event on the NEXT slide only
$('a[href=#box'+window.slide+']').click()
}
setInterval(nextSlide,5000);
This way every 5 seconds the click event on the link to move to the NEXT slide will be triggered (and not all of them).
Hope this helps!
