233334 - SVG script tag syntax different from [IE, Batik]

Status: RESOLVED DUPLICATE of bug 62485

(Core :: SVG, defect)

Description

Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7a) Gecko/20040205

For a straight svg file - i.e., no embeds or object elements - one that has a
document element like

<s:svg xmlns:s="http://www.w3.org/2000/svg" >...</s:svg>

IE + Adobe and Batik use a different script tag syntax than Mozilla does.  It
would be **good** if all three agreed.  This syntax  works for Mozilla -

       <script type='text/javascript' src='svg1b.js'
         xmlns='http://www.w3.org/1999/xhtml'/>

This for works for IE + Adobe and Batik -

       <script type='text/ecmascript' xlink:href="svg1b.js"
         xmlns:xlink='http://www.w3.org/1999/xlink'/>

(Hope the angle brackets show up OK)

I am not sure that the SVG Rec actually specifies a syntax, but leading browsers
should use the same form.  Right now, each one ignores the other, so you can
insert a version for each browser, but that is an irritating work-around.

I suggest allowing Moz to accept **either** form so as not to break backwards
compatibility.

There is a similar issue with inline scripts, except that you do not need the
xlink and href/src parts.

Reproducible: Always
Steps to Reproduce:
1.Create an external javascript file that just has an alert in it, such as 

    alert('This is a test')

This alert should pop up when the script executes - no user action is required.

2. Create a working svg file, and verify that it works on all three browsers.

3.  Insert a script element into the svg document using one of the syntax
exampes given above.  Reload the svg file.  For the browser(s) it works on, an
alert will pop up.  For the other(s), it will not.  Change to the other syntax
and verify that which browsers pop up the alert change to the other set.

Insert another script element with the other syntax, so that both forms are in
one svg file.  Reload the browers and verify that all three now pop up the alert.

Actual Results:  
Depending on which form of the script element is used, either IE and Batik, or
Moz will pop up the alert.  Only if both forms are inserted into the same svg
document will all three browsers act as desired.

Expected Results:  
All SVG browsers should accept the same syntax for script elements.

The Adobe SVG Viewer plug-in (rather than MSIE itself) and Batik are indeed
following the SVG recommendation [1]. They give a sample SVG document with
script [2] that displays on Mozilla-with-SVG but does not react to mouse clicks.

text/ecmascript is not a registered MIME type. mozilla.org's possition seems to
be that the W3C should not be specifying MIME types in their specifications
without first having them registered. Whether Mozilla should just add
text/ecmascript and other widely used MIME types to make the lives of Web
developers easier or not is questionable. However this issue is tracked by bug
62485. You may wish to vote or comment there.
