1. How to integrate eJOY to a video web

1.1. Get the element class of the video web from the Developer Tools view

  • Open Developer Tools

Right click on the website, choose Inspect. Or you can press and hold Ctrl+Shift+I  for Windows (or Cmd+Opt+I for Mac) to open DevTools.

Under the Element tab of  Developer Tools, press Ctrl + F (Windows) or Control + F (Mac) to search on the Element tabs. (1)

On the search bar, enter the subtitle to search for it (2). The below example is:  “but a whole climbing adventure”.

Look for the ” class ” tag closest to the subtitle line found in Element tab. You’ll then see the content for element class. In this case, it is: vp-captions , the one inside the ” ” (the quote). (3)

1.2. Integration

  • Click eJOY icon on the top right of the browser => Settings icon.
  • Then, in Settings page:

>> Click Integrate Video Sites (1)

>> Manually integrated sites (2)

>> Choose “Add new” (3)

An “Edit video site” window will appear.

>> Input the video site’s URL. Eg: (1)

>> Click on “Update” (3)

1.3. Look up subtitle on the newly integrated video web

Back to the video web, press F5 or refresh the web to activate eJOY. Now, you can start looking up words or turning on Auto Translate to understand video content better.

2. Issue: Fail to integrate eJOY

These are 3 common reasons why you can’t integrate eJOY to the video web:

  • You got the incorrect Element class
  • You couldn’t find the element class
  • Other cases that we haven’t experienced before

2.1. 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”.

2.2. 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

  • 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.

2.3. Require integrate

If you have difficulty integrating the eJOY extension yourself to look up words on video pages with other subtitles, you can submit an integration request through our form by pressing "Request integration" (Require integration).

However, only Pro accounts can submit this request. After upgrading to a Pro account, you can access the integrated request form from the customer support menu on the eJOY website. We will process your request as soon as possible.

I hope that this article can help you integrate eJOY successfully to your desired video webs and then this helps you learn English with joy and ease. Over time, we will update our list of video webs with full support thanks to your feedback.

Happy learning to you!
