Hi ALL,

I'm trying to reproduce in B4I a simple app that I have done on B4X but I have the following Problem.

In b4x using the following code, I was able to hide the header, the footer, and navigation control of the web page that I load inside the webview :

Private Sub WebView1_PageFinished (Url As String)
WebView1.loadUrl("javascriptfunction() { document.getElementById('navigation_icons').remove();})()")
WebView1.loadUrl("javascriptfunction() { document.getElementById('logo').remove();})()")
WebView1.loadUrl("javascriptfunction() { document.getElementById('topBar').remove();})()")
WebView1.loadUrl("javascriptfunction() { document.getElementsByClassName('uk-section uk-padding-large')[0].style.display='none';})()")
ProgressDialogHide
End Sub

In B4i with the code above indicated nothing happens, the footer the header, the icon, and the web page navigation are still there,

I have tried with web view and
