how to automatically scroll down a html page?

Question

I'm trying to start each page after the homepage about 500px down, similar to this website: http://unionstationdenver.com/

You'll notice when viewing pages after the homepage, you're automatically scrolled down without notice but you can than scroll up to revel the featured slider again.

I've played with scrolledHeight but I dont think that is what I need????

Basically I have a featured section that is on top of all my content pages, but you shouldn't be able to see this section until you scroll up. Any help?

You can use .scrollIntoView() for this. It will bring a specific element into the viewport.

Example:

document.getElementById( 'bottom' ).scrollIntoView();

Demo: http://jsfiddle.net/ThinkingStiff/DG8yR/

Script:

function top() {
    document.getElementById( 'top' ).scrollIntoView();    
};

function bottom() {
    document.getElementById( 'bottom' ).scrollIntoView();
    window.setTimeout( function () { top(); }, 2000 );
};

bottom();

HTML:

<div id="top">top</div>
<div id="bottom">bottom</div>

CSS:

#top {
    border: 1px solid black;
    height: 3000px;
}

#bottom {
    border: 1px solid red;
}

Solution 2

You can use two different techniques to achieve this.

The first one is with javascript: set the scrollTop property of the scrollable element (e.g. document.body.scrollTop = 1000;).

The second is setting the link to point to a specific id in the page e.g.

<a href="mypage.html#sectionOne">section one</a>

Then if in your target page you'll have that ID the page will be scrolled automatically.

Solution 3

here is the example using Pure JavaScript

function scrollpage() {		
	function f() 
	{
		window.scrollTo(0,i);
		if(status==0) {
   			i=i+40;
			if(i>=Height){	status=1; } 
		} else {
			i=i-40;
			if(i<=1){	status=0; }  // if you don't want continue scroll then remove this line
		}
	setTimeout( f, 0.01 );
	}f();
}
var Height=document.documentElement.scrollHeight;
var i=1,j=Height,status=0;
scrollpage();
</script>

<style type="text/css">

	#top { border: 1px solid black;  height: 20000px; }
	#bottom { border: 1px solid red; }

</style>

<div id="top">top</div>
<div id="bottom">bottom</div>

Use document.scrollTop to change the position of the document. Set the scrollTop of the document equal to the bottom of the featured section of your site

scrollTop is applicable just to a DOM element, not to the document

For your first technique, how do you get it so it's down to the position of a specific element?

[Admin]

Yes I have that about doing anchors but that is the last resort. I just can't tell how these guys did it unionstationdenver.com

@Wex in plain javascript you can find the position of an element inside a document like this: var topPosition = document.getElementById("myElement").offsetTop;

@Hambone you can see in this script link that they are using the scrollTo method of the window object. More info: scrollTo on mozilla

This solution works for me under IE but not Chrome. Any ideas?

[jfritz42]

More info: it works in Chrome on the first page load but not on refresh. I think it's due to this bug: code.google.com/p/chromium/issues/detail?id=280460. If I hard-refresh the page it works, i.e. clicking in the URL bar and hitting enter. But soft-resets like the page refreshing or clicking the refresh button (or hitting F5) do not work.
