168261 - 999.com.cn - IE4/NN4 proprietary code, JS mimetypes

Status: RESOLVED INVALID

(Tech Evangelism Graveyard :: Chinese-Simplified, defect)

Description

Issue 1:

Many advertising scripts on this page are served by a servlet. For example,

http://ad.999.com.cn:8080/servlet/adshow?channelno=572&js=on

This servlet returns a Content-Type of text/html for JavaScript. This does not
cause problems at this point however it is something that should be fixed since
it can affect operations such as view source, file save etc.

Issue 2:

Advertising scripts produced by the adshow servlet create custom JavaScript for
ads which are in many ways identical. This increases the size of JavaScript that
must be downloaded by the client and increases the page load time especially for
dialup users. By creating reusable JavaScript functions which are linked to from
the main page, the total download time can be decreased.

Issue 3: 

Advertising Scripts document.write STYLE tags into the BODY of HTML documents
which is not valid HTML.

Advertising Scripts use Internet Explorer and Netscape Navigator 4 proprietary
Javascript/DOM functions and do not support Netscape Gecko or Mozilla.

I will attach scripts which illustrate the problems.

Attachment: Fixed version of adshow Flash Ad script

Issue 4:
Issue 4:

Some advertising scripts produced by adshow produce OBJECT tags for flash
animations. These scripts incorrectly give each of the flash animation objects
the same ID attribute value 'button' and name their FSCommand handling
functions with the same name 'button_FSCommand' even though many ads may be
served with the same IDs. These scripts also fail to provide a NAME attribute
for the EMBED tag. The NAME attribute on the embed tag is necessary in order
for the Flash FSCommand scripting to work correctly.

Comment 7

[Hallvord R. M. Steen [:hallvors]]

amazingly, some 11 years later this page still contains code like

strMediaPlayer = document.all("iMediaPlayer");

However, the media player doesn't work in IE8 either. And in IE8, no Flash content appears so the page is more broken than in Firefox ;-)

The ads issues do not exist anymore.
I will close AS INVALID, and if someone think there is a specific issue on a specific page with regards to Web compat, please create a new Bug with the description of the issue.
