passing data to javascript from xml files

Hi there I'm experimenting with linking tours together and want to be able to control/effect/change data within a javascript file from an xml file.

For example I have two tours one which links to a panorama in the other and vice versa I have managed to do this one way through javascript to the xml file but can't figure out the reverse route through javascript prob just tired and not thinking straight

Hi Klaus:

Using code similar to the below, I can't seem to get information from a <data/> element passed to a Javascript function. Is this not possible currently?

Quellcode

//javascript:
var myText = krpano().call("get(data[myData].content);");
document.getElementById("somediv").innerHTML = "<span><strong>" + myText + "</strong></span>";

<!-- XML: -->
<data name="myData">
	<p>Hello<br />World</p>
</data>


Thanks in advance,

Patrick

OK, so the call may not return data.
Big deal, almost assuredly, krpano can run javascript too.
JS -> Run krpano function, do variable stuff, run JS function to update the DOM.

Easy peazy.

Hi Sacha:

I don't quite understand what you mean... Are you saying there's a way to get the data element's text into a Javascript function (from krpano xml --> javascript in the page)? That's what I'm trying to do... and it comes up as nothing, empty, or fails without error.

Or are you saying I can just run the Javascript from right within the XML? Or... ?

Thanks,

Patrick

Exactly, you can grab the data element with krpano and use it, and you should be able to call a js function in krpano with those contents or at least, I don't see why not?

I don't think you getting me, call your js function to call your krpano function which gets your data content and call that content as the parameter in a js function which then uses that to update your dom.

Do you have a working test Sacha? Love to see it! I've been trying various methods for a while (see other posts in the forum here). I can successfully call this and other JS from krpano; jsut can't get info from krpano xml into the javascript.

Sigh.

OK, below is the working implementation (both ways, from Javascript to KRPano or the reverse):

//javascript:
var myText;
myText = krpano().get("data[someData].content");

<!-- XML: -->
<!-- call javascript function "someFunction(arg1, arg2, arg3, [arg...])"-->
js( someFunction(get(data[someData].content), BlahBlah, Another Line of Blah) ) ;


Thanks for putting up with my whinery *g*

HTH,

You bastard, and I just finished my example. ;)

This passes a variable into krpano, increments it, and passes it back out ..

Hopefully, I learned something here as well.

Well, you one-upped me with an actual example. ;-) Good work!

WHEW.

Cheers,

Patrick

ps: as was succinctly put to me, off-list, this morning:
"call() does not have a returnvalue, get() does."
