IFRAMEs on the wiki weren't being styled correctly in IE. I tracked down the cause: elem.setAttribute('style', cssStyleStr ) does not work in Internet Explorer. A cross-browser way to do it is:

     elem.setAttribute( 'style', cssStyleStr ); = cssStyleStr;

Also, to eliminate the sunken border on the IFRAME in IE it is necessary to set:

     elem.frameBorder = "0"; // NOTE: case sensitive property name

See for more details.

Also... the logic for extracting the style="..." content chops off the last character. And it leaves the style in the ALT and TITLE tags, which is kinda icky.

There's also a missing semicolon in the "var content = ..." line.

Here's a replacement:

 function renderTravellerMap(){
  if (!document.getElementById('bodyContent')) return;
  var as = document.getElementById('bodyContent').getElementsByTagName('a');
  for (var i = as.length-1; i>=0; i--){
   var a = as[i];
   if (a.href.indexOf('http:'+'//') == 0){
    if ((' '+a.parentNode.className+' ').indexOf(' nochart ') == -1){
     var iframe = document.createElement('iframe');
     iframe.src = a.href;
     var content = a.textContent || a.innerHTML || 'This is a map';
     if (content.indexOf('style="') >=0 ) {
        var start = content.indexOf('style="');
        var end   = content.indexOf('"', start+7 );
        var style = content.substring( start+7, end );
        iframe.setAttribute('style', style); = style;
        content = content.substring( 0, start ) + content.substring( end + 1 );
     iframe.alt = content;
     iframe.title = content;
     iframe.frameBorder = "no";
     iframe.scrolling = "no";
     a.parentNode.replaceChild(iframe, a);

NOTE: The the URL is split into two strings to avoid having this code be turned into a hyperlink by mediawiki's processing... and then turned into an IFRAME by having the renderTravellerMap() function style it since the URL matches!

I've updated the common.js with these changes. Please test the wiki version to make sure I didn't screw up the copy and paste. Tjoneslo 13:51, 6 February 2008 (UTC)
