If you embed an SVG document in a HTML document with IE and Adobe SVG
viewer then there is a method getWindow exposed on the embed element
object that you can call to access the window object of the viewer
which is also the global object meaning global functions are
properties of that window object.
Example HTML:
<embed name="svg1"
type="image/svg+xml"
src="file.svg"
width="200" height="200"></embed>
Then script in the HTML document can do e.g.
var svgDocument = null, svgWindow = null;
window.onload = function (evt) {
var embed = document.embeds.svg1;
if (embed != null && typeof embed.getSVGDocument != 'undefined') {
svgDocument = embed.getSVGDocument();
}
if (embed != null && typeof embed.getWindow != 'undefined') {
svgWindow = embed.getWindow();
}
}
Once that has been done you can call global functions in the SVG
document as e.g.
if (svgWindow != null && typeof svgWindow.functionName != 'undefined') {
svgWindow.functionName();
}
It should not matter whether the script element in the SVG document
has type="text/javascript" or type="text/ecmascript" as long as the
viewer does not use its internal script engine. By default within IE
it uses the MS JScript engine.
