The JavaScript core language itself has no file inclusion or import
mechanism. You need to use the inclusion mechanism of the host
language e.g. in HTML
<script type="text/javascript" src="file.js"></script>
in SVG
<script type="text/ecmascript"
xmlns:xlink="http://www.w3.org/1999/xlink";
xlink:href="file.js" />
Of course with the DOM you can create script elements dynamically and
DOM implementations like that in Mozilla by now do support loading
script dynamically that way, see the example at
<http://home.arcor.de/martin.honnen/svg/test2006030201.svg>
where
var scriptElement =
document.createElementNS('http://www.w3.org/2000/svg', 'script');
scriptElement.setAttributeNS(null, 'type', 'text/ecmascript');
scriptElement.setAttributeNS('http://www.w3.org/1999/xlink',
'xlink:href', url);
document.documentElement.appendChild(scriptElement);
is used to dynamically create and insert an SVG script element when
the blue rectangle is clicked.
Other implementations like Adobe SVG viewer 3.0, Batik squiggle 1.6 or
Opera 9 preview however do not seem to load the script file referenced
by the dynamically inserted script element.
