WebView1 to WebView2 (vb.net) RRS feed

  • Question

  • With Webview1 becoming Obsolete (much quicker then the original "WebBrowser" component) I am making the switch from webview1 to webview2. 

    However ; just like transitioning from WebBrowser Control to WebView1 I had a lot to "learn" In this case I need to know how to change my "invoke script" to the newest format.

    I know I have to 

    Imports Microsoft.Web.WebView2.Core.CoreWebView2

    Then I know it has changed from InvokeScript to WebView.CoreWebView2.ExecuteScriptAsync , I know you can and should add the script to be executed on document ready. However my old style isn't working. 


    Dim name As String = Await WebView1.InvokeScriptAsync("eval", New String() {"document.getElementsByClassName('jsx-2835528490')[1].innerText.toString();"})


    Dim name As String = Await WebView21.CoreWebView2.ExecuteScriptAsync("eval", New String() {"document.getElementsByClassName('jsx-2835528490')[1].innerText.toString();"})
    I am being told it is 

    "Too Many Arguments" Which I understand (that is doesn't allow for the same number of arguments" however what can I change to make this work? 

    should it be just 


    I'm missing something here.

    Thank you everyone for your help

  • This is how it works. However it is adding a " {Quote} to the label. Which makes no sense to me. It should just display the innertext which doesn't have a " {quote}

  • I ended up using .replace to remove the double quotes. But would prefer to know why they are even present.

    Yes, you can directly inject code into the method:

    >>However it is adding a " {Quote} to the label

    It seems to have something to do with the value that your script code get.

    Did you check the value of 'innerText' ?
