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" />

<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>

- Does the console return any error when you load the page / click on the link ? By the way, your code contains a lot of errors. – enguerranws Commented May 21, 2014 at 8:30
- It says uncaught syntax error: Unexpected token ILLEGAL – Bryan Fajardo Commented May 21, 2014 at 8:32
- So correct your code, and that will be fine :) – enguerranws Commented May 21, 2014 at 8:34
- actually, nvm, I had changed something in the index.php. But I reverted it and the console is not showing any errors. srry. but its not working – Bryan Fajardo Commented May 21, 2014 at 8:34
- Would you be so kind as to point the errors to me? I mean, there is a reason I am posting this on stack overflow, if I knew how to correct the errors myself I would have done it. – Bryan Fajardo Commented May 21, 2014 at 8:39

Reset to default 9You need to take into account the scrollTop AND offset of the parent div:
JSFiddle: http://jsfiddle/TrueBlueAussie/Uafxz/2/
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.
You actually don't target the good element to animate scrollTop :
$('html,body').animate({scrollTop: divPosition.top}, "fast"); // instead of #main_wrapper #main
And as said in ment, your code contains a lot of errors or non-standard notation. For example, you use 3 script tag and 3 function that do the same job. That could be done with only one.
