Integration into parcel bundler

Hello,
I'm trying to embed the pano viewer into an existing project which is based on the parcel bundler. When i just load an additional script via the index.html, the embedpano function can not be found (Uncaught ReferenceError: embedpano is not defined).
Does anyone know how to manage this? *confused* Any help is greatly appreciated!
Sebastian

You need to call the embedpano function after the krpano script is loaded.
As it's done in the krpano default html synchronously or use load event if you load script dynamically.

Thanks for your reply. The problem with this method is that the krpano is then loaded in separately, so in the other scripts of my site I can not access the krpano object and its functions. I want to interactively switch on/off panoramas using different buttons than the ones offered in the viewer, for example.

You can acces krpano object like this

Source code

 
1

const krpano = document.getElementById('krpanoSWFObject').get('global');

Where krpanoSWFObject is the id that you pass to the embedpano

Source code

 
1

embedpano({ id:"krpanoSWFObject"....})

 We should be able to access the krpano object.
 Also, we should get an error as the tour.xml is not present (nor are any other needed files).

It seems this error is specific to Codesandbox or Parcel.
For example this works fine locally, but have an error in Codesandbox https://codesandbox.io/s/admiring-dawn-0…ile=/index.html

When you use static template without bundler it works https://codesandbox.io/s/gallant-pateu-5…ile=/index.html
