Javascript Question

Scroll to a div using jquery

so I have a page that has a fixed link bar on the side. I'd like to scroll to the different divs. Basically the page is just one long website, where I'd like to scroll to different divs using the menu box to the side. Here is the jquery I have so far

$(document).ready(function() {

$('#contactlink').click = function (){
$(document).scrollTo('#contact');
}

});


The issue is it is automatically going to the contact div when it loads, then when I press the #contactlink in the menu it scrolls back to the top.

EDIT: HTML

<!DOCTYPE html>

<html lang="en">

<head>
<meta charset="utf-8">

<!-- jQuery-->
<script src = "<?php echo base_url() ?>assets/js/jquery.js"></script>

<!-- .js file-->
<script src = "<?php echo base_url() ?>assets/js/pagetwo.js"></script>

<link rel="stylesheet" type="text/css" href="<?php echo base_url()?>assets/css/reset.css" />

<!-- .css for page -->
<link rel="stylesheet" type="text/css" href="<?php echo base_url()?>assets/css/pagetwo.css"/>

<!-- page title-->
<title><!-- Insert Title --></title>


</head>
<body>
<div id="container">

<div id="sidebar">
<ul>
<li><a id = "aboutlink" href="#">auck</a></li>
<li><a id = "peojectslink" href="#">Projects</a></li>
<li><a id = "resumelink" href="#">Resume</a></li>
<li><a id = "contactlink" href="#">Contact</a></li>
</ul>
</div>

<div id="content">
<div class="" id="about">
<p class="header">uck</p>
<p class="info">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Thanks for the help

Answer

First, your code does not contain a contact div, it has a contacts div!!!

In sidebar you have contact in the div at the bottom of the page you have contacts. I removed the final s for the code sample. (you also misspelled the projectslink id in the sidebar).

Second, take a look at some of the examples for click on the jQuery reference page. You have to use click like, object.click( function() { // Your code here } ); in order to bind a click event handler to the object.... Like in my example below. As an aside, you can also just trigger a click on an object by using it without arguments, like object.click().

Third, scrollTo is a plugin in jQuery. I don't know if you have the plugin installed. You can't use scrollTo() without the plugin. In this case, the functionality you desire is only 2 lines of code, so I see no reason to use the plugin.

Ok, now on to a solution.

The code below will scroll to the correct div if you click a link in the sidebar. The window does have to be big enough to allow scrolling:

  // This is a functions that scrolls to #{blah}link
function goToByScroll(id){
      // Remove "link" from the ID
    id = id.replace("link", "");
      // Scroll
    $('html,body').animate({
        scrollTop: $("#"+id).offset().top},
        'slow');
}

$("#sidebar > ul > li > a").click(function(e) { 
      // Prevent a page reload when a link is pressed
    e.preventDefault(); 
      // Call the scroll function
    goToByScroll(this.id);           
});

Live Example

PS: Obviously you should have a compelling reason to go this route instead of using anchor tags <a href="#gohere">blah</a> ... <a name="gohere">blah title</a>
