How do I get a JS variable in a webviewer to the app?

[Noo00B]

Hey guys,Is there any way to get the variable data in a js script to the app ? please help me.

Hello @Noo00B, and welcome to the App Inventor Community!
Unfortunately, I wasn't quite able to understand your question.
Do you mean you want to run a JS script in App Inventor?

I mean I want to get the data content of a var. for example,
var name = "Name";
then a some blocks to get the "name" to the app (global variable)

The link given in post #3 shows exactly that!

[Noo00B]

You mean this ?

[nishyanthkumar]

Yes, but you will need to upload the HTML file onto App Inventor and then open it through the WebViewer.

[Noo00B]

that's the problem. i want to do it with internet

[nishyanthkumar]

So upload the file to the app while it's already running, via the web?

[Noo00B]

good idea. When I do that does it load other css,js files on the internet ?

[nishyanthkumar]

That's a tough one! I haven't found anything matching that as of the current. Maybe you could use firebaseDB to upload and get the files.

[Noo00B]

thanks, I going to combine all js and css to a one html lol

[nishyanthkumar]

Makes sense to do it that way.

[Noo00B]

Thanks for the help

If paths are all set correctly the page should work just as it would on your computer browser. However:

• the webviewer is not like a normal browser and may struggle to run some css, javascript or other frameworks
• You may need to apply some if statements to test if you are running the webpage inside the app, the webviewstring is only available in the app, it does not exist in the wild

Will the CustomWebView help mitigate this?

[Noo00B]

what is it ? i'm new to this app inventor .

It's an extension, you can find it here:

I'm trying to download a data image URI and I get that same error that @MathMan05 was experiencing earlier this year. Is there some activity starter method or extension to fix it.
