Please try this from the inspector console:
typeof document.getElementById('dosya_listesi_result' )
or
console.log( typeof document.getElementById( 'dosya_listesi_result' ) )

The strange thing is that this code:
oWebView:Eval('SendToFWH( document.getElementById("example") )' )
returns "null"
why ?

Solved
oWebView:Eval( 'window.onload = function () { SendToFWH( document.getElementById("example").innerHTML ) }' )

Goodmorning Antonio,
Can you please share full code in sample app? When I insert this line, there is not any messagebox anymore.

Hi Antonio,
I have changed my code like this.
Code: Select all | Expand
aaa := "document.getElementById('dosya_listesi_result' ).innerHTML"
oWebView:Eval( 'SendToFWH( '+aaa+ ' )' )
It displays the all record in table.
But your code is more readable than mine.
Code: Select all | Expand
oWebView:Eval( 'window.onload = function () { SendToFWH( document.getElementById("dosya_listesi_result").innerHTML ) }' )
There is not any showmessage box.
I want to ask something. We need sleep() function to wait for windows loading web site code. But every customer has different internet speed. We should change seconds every customer in sleep function. I have seen a different "await" command in stackoverflow.com.
Code: Select all | Expand
await ExecuteScriptAsync("document.getElementById('DropDownList').selectedIndex");
Is your code "window.onload" same as this await command?

Hakan,
can't you use a timer and check document.readyState first?
Best regards,
Otto

Morning Hakan,
This is the code:
Code: Select all | Expand
#include "FiveWin.ch"
//----------------------------------------------------------------------------//
function Main()
local oWebView := TWebView():New(), aaa
oWebView:bOnBind = { | cJson, nCalls | MsgInfo( cJson, nCalls ) }
oWebView:Bind( "SendToFWH" )
oWebView:Navigate( "https://datatables.net/examples/data_sources/js_array" )
Sleep( 200 )
oWebView:Eval( 'window.onload = function () { SendToFWH( document.getElementById("example").innerHTML ) }' )
oWebView:Run()
oWebView:Destroy()
return nil
Going to check your await command...

Hakan,
ExecuteScriptAsync() seems to be a method of WebView2 that has not been implemented in webview.dll yet
https://docs.microsoft.com/en-us/dotnet/api/microsoft.web.webview2.wpf.webview2.executescriptasync?view=webview2-dotnet-1.0.1245.22I am going to ask Steffen...
