Im trying to use simple jquery offset() and animate to make my div scroll to the desired div when the user clicks on a link.
Basically, when the user clicks blog it will go to test1 user clicks Contact it will move to test2 user clicks Work it will move to test3.
I implemented some code I had used in a previous project (it had worked before) but the scrolls are not working correctly this time and I really don't know the reason why. I tried searching for a solution but web development has been an on and off thing for me and I don't understand some of the explanations :/ Any help would be appreciated.
EditOne: had to update the html, still not working.
The HTML:
<html>
<head>
<meta name="description" content="" />
<meta name="keywords" content="" />
<meta name="author" content="" />
<script type="text/javascript" src="jquery.js"></script>
<link rel="stylesheet" type="text/css" href="index.css" />
<link rel="stylesheet" type="text/css" href="reset.css" />
<title>Bryan the Lion</title>
</head>
<body>
<script type="text/javascript">
function go_One(){
var divPosition = $('.test1').offset();
$('#main_wrapper #main').animate({scrollTop: divPosition.top}, "fast");
}
</script>
<script type="text/javascript">
function go_Two(){
var divPosition = $('.test2').offset();
$('#main_wrapper #main').animate({scrollTop: divPosition.top}, "fast");
}
</script>
<script type="text/javascript">
function go_Three(){
var divPosition = $('.test3').offset();
$('#main_wrapper #main').animate({scrollTop: divPosition.top}, "fast");
}
</script>
<div id = "header">
<h1>Title</h1>
</div>
<div id = "main_box">
<div id = "designHex">
</div>
<div id ="nav">
<ul>
<li id = "Blog"><a href="#" onclick= "go_One()"></a></li>
<li id = "Contact"><a href="#"onclick= "go_Two()"></a></li>
<li id = "Work"><a href="#" onclick= "go_Three()"></a></li>
</ul>
</div>
<div id = "main_wrapper">
<div id ="main">
<div class = "test1">
<p>some div</p>
</div>
<div class = "test2" >
<p>some div2</p>
</div>
<div class = "test3" >
<p>some div3</p>
</div>
</div>
</div>
</div>
</body>
</html>
The CSS: Of most importance here I think are main_wrapper, main, and test(1)(2)(3)
body{
height: 100% ;
background: url(images/gplaypattern.png);
}
@font-face {
font-family: "AlexBrush";
src: url(fonts/AlexBrush-Regular.ttf) format("truetype");
}
#header{
height: 100px ;
margin-bottom: 20px ;
}
#main_box{
margin: 0 auto ;
width: 80% ;
height: 52 0px ;
}
#main_wrapper{
margin-left: 45% ;
width: 67%;
overflow: hidden;
}
#main_wrapper #main{
width: 103%;
height: 500px ;
overflow-y:scroll;
}
.test1{
height: 500px ;
background: yellow;
}
.test2{
height: 500px ;
background: blue;
}
.test3{
height: 500px ;
background: gray;
}
#nav{
float: left;
width: 275px ;
height: 450px ;
margin-left: 3% ;
}
#nav ul li a{
display: block;
width: 100% ;
height: 150px ;
}
#nav ul li a:hover{
cursor: pointer;
}
#nav #Blog{
background: url(images/Blog.png);
}
#nav #Blog:hover{
background: url(images/Blog_hover.png);
}
#nav #Contact{
background: url(images/Contact.png);
}
#nav #Contact:hover{
background: url(images/Contact_hover.png);
}
#nav #Work{
background: url(images/Work.png);
}
#nav #Work:hover{
background: url(images/Work_hover.png);
}
#designHex{
background: rgba(255,255,255, 0.3);
height: 150px ;
width: 150px ;
position: absolute;
top: 50px ;
left: 5% ;
}
You need to take into account the scrollTop AND offset of the parent div:
function scrollTo(selector) {
var offset = $(selector).offset();
var $main = $('#main');
$main.animate({
scrollTop: offset.top - ($main.offset().top - $main.scrollTop())
}, "fast");
}
I changed your code to use a single function (passing the target selector). I removed the second id selector as ids are unique and id lookup is the fastest type of lookup anyway (no point slowing it down with a second search).
Note: I had to hide your designHex element for the JSFiddle as it overlapped the first link.
