Read user variables from plugin script

I've got a client that wants to use their BrightSign XT player to display a sales dashboard.  The website does require a login, which I've been able to execute through a plugin.  However, I'd prefer the store the login credentials (username and password) in User Variables, so it's easier for the client to maintain them. 

However, I have no idea how to do this.  I've tried some different methods, but none seem to work. 

 

Here is the content of the plugin script.

---- START PLUGIN ---

Function sendWebLogin_Initialize(msgPort As Object, userVariables As Object, bsp As Object)
 
  sendWebLogin = newSendWebLogin(msgPort, userVariables, bsp)
  return sendWebLogin
  
End Function  

Function newSendWebLogin(msgPort As Object, userVariables As Object, bsp As Object)  

'create the new object
    
    s={}
    s.objectName = "sendWebLogin_object"
    s.msgPort =   msgPort
    s.userVariables = userVariables
    s.bsp = bsp
    s.htmlwidget = invalid ' We'll use the FindHTMLWidget method to set this later
    s.ProcessEvent =  sendWebLogin_ProcessEvent
    
    return s 
End Function 
    
    
Function sendWebLogin_ProcessEvent(event As Object) as boolean

       m.htmlwidget = FindHTMLWidget(m.bsp) 'find the htmlwidget in the presentation

      'Receive a plugin message
      if type(event) = "roHtmlWidgetEvent" then
        eventData = event.getData()
            if type(eventData) = "roAssociativeArray" and type(eventData.reason) = "roString" then
            print "HELLOOOOOOOOO"
                
                 if eventData.reason = "load-finished" then                   
                    m.htmlwidget.InjectJavaScript("document.getElementById('username').value='my_username';document.getElementById('password').value='my_password';document.getElementById('Login').click();")
                end if
            end if
    end if 
              
    return false 
    
End Function
    
 
Function FindHTMLWidget(bsp)
    for each baZone in bsp.sign.zonesHSM
        if baZone.loadingHtmlWidget <> invalid then
            return baZone.loadingHtmlWidget
        end if
    end for
    print "Couldn't find htmlwidget"
    return false
End Function

--- END PLUGIN

  I got it working and wanted to share the script.  This script reads three user variables:
  salesforce_username
  salesforce_password
  page_refresh_minutes

  This is for a client that wants to view their salesforce dashboard with auto-login.  Note that we have to add the IP range of the client office to the Salesforce profile under "Trusted Domain" (or something like that) to disable 2FA when you login.
  
  It will then log them in automatically, and then refresh the page every xx minutes as specified in the last user variable.  If that variable is missing or set to 0, it will not refresh.

  Here's the script:

   

  Function sendWebLogin_Initialize(msgPort As Object, userVariables As Object, bsp As Object)
   
    sendWebLogin = newSendWebLogin(msgPort, userVariables, bsp)
    return sendWebLogin
    
  End Function  

  
  Function newSendWebLogin(msgPort As Object, userVariables As Object, bsp As Object)  

  'create the new object
      
      s={}
      s.objectName = "sendWebLogin_object"
      s.msgPort =   msgPort
      s.userVariables = userVariables
      s.bsp = bsp
      s.htmlwidget = invalid ' We'll use the FindHTMLWidget method to set this later
      s.ProcessEvent =  sendWebLogin_ProcessEvent
      
      return s 
  End Function 
      
      
  Function sendWebLogin_ProcessEvent(event As Object) as boolean

         m.htmlwidget = FindHTMLWidget(m.bsp) 'find the htmlwidget in the presentation

        'Receive a plugin message
        if type(event) = "roHtmlWidgetEvent" then
          eventData = event.getData()
              if type(eventData) = "roAssociativeArray" and type(eventData.reason) = "roString" then
                  
                   if eventData.reason = "load-finished" then
                   
                       ' Read the user variable with the login username                      
                       if m.userVariables["salesforce_username"] <> invalid
                               login_username=m.userVariables["salesforce_username"].currentValue$
                       else
                               login_username="salesforce_username variable undefinded"
                       end if
                       
                       ' Read the user variable with the login password
                       if m.userVariables["salesforce_password"] <> invalid
                               login_password=m.userVariables["salesforce_password"].currentValue$
                       else
                               login_password="salesforce_password variable undefinded"
                       end if
                       
                      'print "login_username is " login_username
                     'print "login_password is " login_password
                       
                      ' Build the java command string from the user data
                      javascript_command = "document.getElementById('username').value='" + login_username + "';document.getElementById('password').value='" + login_password + "';document.getElementById('Login').click();"
                      
                      'Inject the script to auto-login
                      m.htmlwidget.InjectJavaScript(javascript_command)

                      ' Read the refresh time (minutes) from the user variables'                    
                       if m.userVariables["page_refresh_minutes"] <> invalid
                               refresh_string=m.userVariables["page_refresh_minutes"].currentValue$
                               refresh_int = refresh_string.ToInt() * 60000
                       else
                               refresh_int = 0
                       end if                                     
                       
                      if (refresh_int > 1000)
                          ' Build the javascript command to refresh the page
                          javascript_command = "window.setInterval('refresh()', " + refresh_int.ToStr() + ");function refresh() { window.location.reload();}"
                          
                          ' Inject a script to refresh the page every xx seconds
                          m.htmlwidget.InjectJavaScript(javascript_command)
                      end if
                      
                  end if
              end if
      end if 
                
      return false 
      
  End Function
