iOS Question B4I hide the header , footer, and navigation of the web page that I load inside a web view or wkwebview

[Nino Caminiti]

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

..

Someone can help me to achieve the same result in B4I ?

Dim wbv As WebView
wbv.EvaluateJavaScript(...) 'only the code inside function I think

Hi @hatzisn Thanks for your answer, I have to use webview or wkwebview? I have to put inside the sub Private Sub WebView1_PageFinished (Url As String). I'm new on this could you provide me an example? Thanks in advance

The type Webview coresponds since a lot B4i versions to the new type of iOS webview.

@hatzisn If try with the code suggested I have the following error:
Variable wbv undeclared (in line 3 of the attached image)
Wrong number of Brackets (in line 4 of the attached image)

It was just an example. You will use webview1 and remove the dim wbv as Webview. Also in the script to be evaluated remove everything after ";" !
