How to pass an array to a plugin

I’ve written a Javascript plugin. I need to pass an array of arrays (array of latitude/longitude pairs) to it. In Javascript it looks like this:

var locData = [
    [59.62856947827632, 3.944420249288397],
    [59.62814600635401, 3.944630157340777],
    [59.62779724440824, 3.944840256674767],
    [59.62757954693874, 3.944887326777842],
    // many more
];

What is the best way to pass that from a krpano xml <plugin> element?

Quote from klaus.krpano

How do you want to store the data in the xml file?

Yes, that is the question. I’m experienced in JavaScript, but new to krpano Script.

Converting everything into XML nodes with strings, passing it and then parsing it into floats and recreating the array structure seems a bit laborious.

I tried this:

<krpano>
	<plugin name="my_plugin" keep="true" url="./path/to/plugin.js"
		<!-- other attributes omitted -->
		polycoordinates="calc(getPolyCoordinates());"
	/>

	<action name="getPolyCoordinates" type="Javascript">
		<![CDATA[
		return JSON.stringify(
			[
				[59.62856947827632, 3.944420249288397],
				[59.62814600635401, 3.944630157340777],
				[59.62779724440824, 3.944840256674767],
				[59.62757954693874, 3.944887326777842],
				// many more ...
			]
		);
		]]>
	</action>
</krpano>

But it does not work. The action is not called before passing the attributes to the plugin, so all I get is the string "calc(getPolyCoordinates());".

Great solution! Thank you very much!
