Call JavaScript function from Unity and vice versa - JavaScript Unity Bridge

UPDATE: many people says that they did not find the source code, here is again the source code in this link, direct link to my Google Drive:

When building a Unity program for web (WebGL), mostly we need to access methods/functions inside Unity from JavaScript (browser scripting).

This example is showing how it can be done. In this example I’m showing how to call JavaScript alert from Unity and then send back some string text to Unity Scene from web browser.

since there are not so many clear examples on youtube about webGL your knowledge is precious thanx for sharing this!!!

legend, better explained than the unity documentation

[bhupiistersingh]

Anyone facing problem of UI elements not taking inputs from browser, please make sure that your start function has WEBGl.captureAllkeyboardinput = false and then build the code.
So in short follow the video thoroughly.

​ @ThirteeNov hi,
what i didn't understand was:
1. I've seen that you had in the project unityloader.js and UnityJS.json files in the folder.
which ones did you use?



2. the index.html i buit was very different than urs (lot more 'div's act) did you just add the scripts in the header and body in 2:36 or did you add/remove anything else?



and 3. in 0:36 it the video did not show how did you call the function from the page button.
from the HTML pages JS file that is.
In my case I don't run the unity project locally but via have a link from remote storage, open an Iframe and inject the content there.
It wasn't clear to me how will the window JS file use the functions of the index.http.

was my question more clear now? apologise for the confusion.

If one "follows the video thoroughly" as a precedent comment said, only half of this demo will work : sending messages from JS to unity.
Sending messages from Unity to JS definitely cannot work, you do not show us the Button's mapping. So after replicating what we see in the video, the Unity button is not mapped.

To map the Unity button "Sent to JS", do the following :
Click on Button on the hierarchy left panel -> on the Inspector panel on the right, click the little "+" under the "On Click()" line -> Under "Runtime Only", select Bridge script -> Select Bridge.SendToJS method.


-Additionnally, correct me if I am wrong, you do not give sources files but only the built project. One can try the result at home by hosting a web server with your built files, but cannot modify it or understand it without sources.-

New Unity users may have a hard time, hope they will read this comment.
