B4J Question access to array variables by webview

[bogdanc]

Hi All!

I used a webview to open my external web.
that web has continuously updating (Ajax / js ) some variables.
These variables are kept in the array.

How to get access to them?

Is there any simplest way instead of use a webview.

Thanks for any ideas.

you asked a similar question already in b4j forum. I suppose the answer will be the same like Erel gave you some days before...

Yes was similar but This time is about variable value kept in the array.
How to get access to it?

You will need to inject JavaScript that reads the array. A better solution will be to remove WebView and use HttpUtils2 to make the requests.

Hi Erel!

I did some simple example:

<!DOCTYPE html>
<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <script>
    var test = ["element1", "element2", "element3"];
    </script>
    <body>  
    </body>
</html>

Then I used a tutorial of: HttpUtils2

But id downloading is as plain text.

So how in this method request access to array?

You will need to parse it the html.
This regex pattern will return the text inside the square brackets:
\[([^]]+)\]

You can then split it and remove spaces and quotes to get the elements.

I understand but an array its dymamicly updated. So I will need to gor example:
Array: test[0] to get this element

It can only be updated if you make a new request.
