(jQuery) Scroll event.. I want to scroll the document to the point specified if the user scroll the page
<p>I want to implement a scroll function.. So the default of scroll is disabled. And if the user use the scroll button, I want it to be set to the point I want.. How can I implement this function? window.scrollTop is not working.. I tried a lot of different methods but all were not working..</p>

<pre><code>$(window).scroll(function() {
     $(body).scrollTop = 3000px;
})
</code></pre>
