invoke ECMAScript-Function
How can I invoke the execution of an ECMA-Script Function from within a
Java method? My JSVGCanvas loads correctly an SVG-Document, executing
all scripts and functions on their respective internal events. I have an
update function there, that I would like to run after setting some data
from outside, as well. Any idea?
TIA,
Robert

Thanks a lot, that worked!
I additionally changed "application/javascript" to "text/ecmascript"
appropriate to my script (and I think sth. like svg-standard).

Get it from the UpdateManager.

Hello Thomas,
thanks for the hint.
But how do I lay my hands on the BridgeContext? Or may I not use
JSVGCanvas or JSVGComponent if I intend to use the Bridge? All fields
and methods that seem helpful to access the BridgeContext I found
protected (as createBridgeContext, userAgent or documentLoader).
Is there another way?
TIA,
Robert

Get a reference to the script Interpreter from the BridgeContext;
Interpreter interp = getInterpreter("application/javascript");
interp.evaluate(yourEcmaScriptCodeStringHere);
If you need to reference Java Objects you might also use:
interp.bindObject(ecmaScriptVarName, javaObject);
