Apart from those fully supported video websites like Netflix, Youtube, with eJOY extension 6, you can integrate the lookup feature on any video web that you want.

If you couldn’t integrate eJOY successfully

There are 3 reasons that you couldn’t integrate eJOY to the video web:

  1. You got the incorrect  Element class
  2. You couldn’t find the element class
  3. Other cases that we haven’t experienced before

Incorrect Element class

Please be informed that the Element class DOES NOT CONTAIN SPACE . If you see an element class like the ones below:

  • class = “captionsText ng-xyz” , or
  • class = “meta-script 9”

Please remove all characters after the space. In these cases, the element class would be “captionsText” or “meta-script”.

Element class not found

Please take a screenshot of the Developer tool view that you couldn’t find the Element class. Then send the following info to eJOY via [email protected]:

  • link to video web that you want to integrate eJOY to
  • screenshot of developer tool view where you couldn’t find the element class

We will send you back with instructions for your special cases. And thanks to your feedback, we can update this guideline with more specific cases.
