Hi,

This is to prevent JavaScript engine from being re-entered. Please use WebView.QueueScriptCall instead.

Thanks!

Hi,

You would do it like this:

Code: Visual Basic.NET
Dim scriptCall = webView.QueueScriptCall("document.getElementById('pt1:r1:0:it2::content').innerText")
scriptCall.OnDone(Function()
    MessageBox.Show(scriptCall.Result.ToString())
End Function)

Note that inside the OnDone callback you use scriptCall.Result to access the result.

Thanks!

Hi,

The sample code is only to show you the idea. You will have to understand the code, adapt it to fit your need, and debug it if you run into any problem. You can't just say "it's not working" and expecting us to fix it for you. If you wish us to look into an error for you, you will need to at least explain what error you are running into and why you believe this error needs to be resolved on our end. For simple compiler errors or logical code errors, you will need to resolve those yourself.

Thanks!

Hi,

Please change Function to Sub:

Code: Visual Basic.NET
Dim scriptCall = webView.QueueScriptCall("document.getElementById('pt1:r1:0:it2::content').innerText")
scriptCall.OnDone(Sub()
    MessageBox.Show(scriptCall.Result.ToString())
End Sub)


Thanks!
