245780 - When you view todays TV listings you cannot click on a TV programme until the page is fully loaded

Status: RESOLVED DUPLICATE of bug 101190

(SeaMonkey :: General, defect)

Description

[Andrew Clark]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040514
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040514

I believe this is to do with not allowing JavaScript to work before the whole
page is loaded. When you click on a TV programme it should bring up a popup
showing programme info, but it doesn't do this until the whole page is loaded.

Now this can take quite a while because there is a lot of programmes to be
displayed.

If Javascript is not enabled then the programme info appears in a new browser
window as instructed by the web site.

Please fix it by final 1.7 Release

Thanks

Reproducible: Always
Steps to Reproduce:
1. go to www.radiotimes.com
2. click on 'Todays TV'
3. click on a TV programme

Actual Results:  
if JavaScript is enabled and the page has not fully loaded then nothing happens
until the page is loaded. Once page has fully loaded then clicking the link
brings up a new popup window.

If Javascript is NOT enabled, the programme info will appear in a new browser
window whether the page has loaded or not.

Expected Results:  
When Javascript is enabled it should run the Javascript code which would bring
up a popup window with programme info.

The page reached at step 3 is 
http://www.radiotimes.com/tv/now.html
and, for starters, has
- 4445 reported errors when the W3C HTML validator chooses HTML 4.01
transitional, many of them are unescaped ampersands in uri's,
- 373 nested tables,
- 318 spacer.gif of various dimensions,
- about 3000 lines of code,
- 7 <script> loaded as the document loads including
<script language="JavaScript">adtag("banner")</script> which creates dynamically
another <script> element for loading a random banner ad like this:
function adtag(type){
document.write( unescape('%3C') + 'script
src="http://bbcww.adbureau.net/jserver/site=' + sitetag + '/area=' + target +
'/aamsz=' + type + '/acc_random=' + target_random + '?" type="text/javascript"
language="JavaScript1.1">' + unescape('%3C') + '/script>');
}
- densely and intensely intricated nested tables with an insane amount of 72
align, 169 &nbsp;, 225 valign, 589 bgcolor declarations

If I examine the Breakfast link (broken to avoid scrolling) located at line 735:

<a
href="/jsp/frameset/index.html?src=/ListingsServlet?event=10&amp;channelId=92&amp;
programmeId=18879697&amp;jspLocation=/jsp/prog_details.jsp" target="_blank"
onclick="spawn_window('/jsp/frameset/index.html?src=/ListingsServlet?event=10&
channelId=92&programmeId=18879697&jspLocation=/jsp/prog_details.jsp',
'prog_details',
'width=550,height=550,resizable=0,toolbar=0,scrollbars=yes,location=0,menubar=0,
status=0,titlebar=0,top=0,left=0'); return false;" class="smallTextLink"
title="Breakfast  (6:00am-9:25am)">Breakfast</a>

The href value is the same but the target attribute value ("_blank") and the
windowName in the window.open call are not the same. The function spawn_window
is located at line 31.

If Javascript support is disabled, then the browser skips <script>s, ignores
many function calls, ignores all onclick event attributes and therefore should
load the document faster. The onclick event handlers will be ignored and the
referenced resource will load in an unnamed _blank window.

This bug turns out to be a duplicate of bug 232209 which is a duplicate of bug
101190. I examined carefully the situation with several browsers and a long page
to load will generate the same actual results and not the expected results; e.g.
MSIE 6 with a popup blocker add-on too (like Linkbar:
http://www.draig.de/LinkBar/ ). So, this behavior is not specific to Mozilla.

I can create a simple testpage for this too.
