The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Fixed Table Header/Scrolling in Mozilla

Asked by mark-b in JavaScript

Tags: , ,

I've created a table with fixed headers that behaves exactly the way I want, but it only works correctly in IE.   This table has fixed headers, scrolling in both directions and synchronized resizing (headers and table data).  Here it is:

<html>
<head>

<style>
 table#headers {table-layout:fixed;background:#eea033;}
 table#data {table-layout:relative;background:#eea033;}
 td, th {vertical-align:top;background:#ffffff;}
</style>
<script language="javascript">
var rh;
var fr;
var ds;
var hs;

function getOnScroll(from) {
      return function () {
            from.scrollLeft = event.srcElement.scrollLeft;
      };
}

function addSyncScroll(from, to) {
      removeSyncScroll(from);
      from.syncScroll = getOnScroll(from);
      from.syncTo = to;
      to.attachEvent("onscroll", from.syncScroll);
}

function removeSyncScroll(from) {
      if (from.syncTo != null) {
            from.syncTo.detachEvent("onscroll", from.syncScroll);
      }

      from.syncTo = null;
      from.syncScroll = null;
}
 
function init() {
  rh = document.getElementById("rh");
  fr = document.getElementById("fr");
  ds = document.getElementById("ds");
  hs = document.getElementById("hs");
  hs.style.top = ds.offsetTop;
  hs.style.left = ds.offsetLeft;
  hs.style.setExpression("width","ds.offsetWidth-(ds.offsetWidth - ds.clientWidth)");
  hs.style.visibility='visible';

  for( i =0; i < rh.childNodes.length; i++ ) {
      rh.childNodes[i].style.setExpression("width","fr.childNodes[" + i + "].offsetWidth");
  }

  addSyncScroll( hs, ds );
}
</script>

There are actually two problems with the Mozilla version:
 1)  Resize of the headers does not happen until the mouse is released on the window.  I CAN live with this.
 2)  The widths of the table headers do not synchronize correctly when the width of the table is greater than the viewport (when the horizontal scrollbar needs to be used to scroll).  I CANNOT live with this.  

I would like the solution to this problem NOT to use XUL or IFrames (if possible, keep the table header a DIV so it does not have external dependencies).

Thank you, and good luck!Start Free Trial
