如何在热点上添加点击事件或在mpetroff / pannellum插件中加载图像事件

Question

Can anyone suggest me with a short example that how to bind click event on hotspot and image load event. I tried using "clickHandlerFunc" attribute but unable to add click handler on hotspot or image. Please suggest me, with any basic click event using "mpetroff/pannellum" panorma. My requirement is to fetch image data on load of image or on click of hotspot.

Thanks!

One suggestion would be to use the scenechange and load API events exposed by Pannellum ( https://pannellum.org/documentation/reference/#api-events ). I think it would indirectly achieve what you are looking for since they trigger every time a new scene is loaded.

scenechange triggers when a scene change is triggered (eg by clicking on a scene hotspot). load triggers when a scene has fully loaded (ie all the images have loaded).

Here is an example of how this would look.

  viewer = pannellum.viewer('panorama', { 
   // Insert your pannellum config here
   });

  viewer.on('scenechange', function (){
   // Insert handler here
  });
