Hello,

I have this redirect URL:
B4X: 
https://localhost:8081/fb/updatepassword/#access_token=eyJhbGciOiJIUzI1NiIsImt&expires_at=1706608981&expires_in=3600&refresh_token=mA8xWwjn&token_type=bearer&type=signup

If i try to get a parameter with this:
B4X: 
Log(ws.UpgradeRequest.GetParameter("access_token"))

it does not return anything.

If i edit URL manually and replace # with ? then it does normally return the parameter.

In both cirumstances, page loaded normally.

As i read, # at URL is used in order to cover single page webapps.

So my question is how to get the parameter after the hashtag?

UPDATE: This question has been asked here. How can i use it in B4J?

Hooray!

I just found the solution:

B4X: 
Log(ws.EvalWithResult("return window.location.hash",Null).Value)

Returns everything after #

if you want to make a map with every parameter, you can do the following:
B4X: 
Private url As String = ws.EvalWithResult("return window.location.hash",Null).Value
    
    If url.ToLowerCase.Contains("#") Then
        Dim hash As String
        hash = url.SubString(url.IndexOf("#") + 1)
        
        Dim result As Map
        result.Initialize
        
        Dim params() As String
        params = Regex.Split("&", hash)
        
        For Each param As String In params
            Dim parts() As String
            parts = Regex.Split("=", param)
            
            If parts.Length = 2 Then...
