Automatic Scroll To Exact Pixel Position
When Page Loads

Generally, when a page is loaded, the upper-left part of the page is visible in the browser window or frame. This article describes how to display a different part of the page by automatically scrolling an exact amount.

The automatic scroll can be done whether the page is by itself in a browser window, within a frame, or within an iframe tag.

The page can be scrolled down from the top and/or in from the left.

Example of use: To display an article by itself in the browser window without header and navigation distractions, the web page can be scrolled down to the headline and right to the edge of the article column.

 
How To Implement Automatic Scrolling

Put this JavaScript somewhere in the web page that will be scrolled.

<script type="text/javascript"><!--
// November 3, 2009, https://www.willmaster.com/
// Copyright 2009 Bontrager Connection, LLC
function AutoScrollOnload() {

// Specify how many pixels from the left 
//    and how many down from the top to 
//    automatically scroll the page.

var InFromLeft = 172;
var DownFromTop = 364;

// No other customization required.

window.scrollTo(InFromLeft,DownFromTop);
}
function AddOnloadEvent(f) {
if(typeof window.onload != 'function') { window.onload = f; }
else {
   var cache = window.onload;
   window.onload = function() {
      if(cache) { cache(); }
      f();
      };
   }
}
AddOnloadEvent(AutoScrollOnload);
//--></script>

Two edits are required, the amount of scroll down from the top and in from the left. The place for the edits is marked.

If you have a tool to measure number of pixels in your browser window, it can be used to determine the amount of scroll. (The Firefox Web Developer add-on has such a tool.)

Otherwise, make a guess. Then load the page, adjust the numbers, and reload until the scroll is correct.

Test your implementation on different browsers, especially if the page is in an iframe. Different browsers my have different line breaks or other rendering that changes the amount to scroll.

When implemented, the web page should automatically scroll by the number of pixels specified when it completes loading - unless the page area is not large enough. No scroll will go beyond the bottom or right edge of the page area.
