[Maark]

first, use code <>

to fix the problem, you need put the player in arguments to get account data

bool triggerServerEvent ( string event, element theElement, [arguments...] )

 

code fixed:

bank = triggerServerEvent("bank-hajs-panel", localPlayer, localPlayer)

(you are sending the event to localPlayer, and sending the localPlayer in arguments to get the data.)

if i help u, give a thanks pls!

You cannot return information from the server side this way. You need the server to trigger a client event back with the balance amount.

The client should be something like this:

-- ...
  triggerServerEvent("bank-hajs-panel", localPlayer) -- request balance from the server
  addEventHandler("onClientBrowserDocumentReady", theBrowser,
    function ()
      bank = triggerServerEvent("bank-hajs-panel", localPlayer)
      executeBrowserJavascript(source, "document.getElementById('gotowka').innerHTML = '"..getPlayerMoney(localPlayer).."$';")
      executeBrowserJavascript(source, "document.getElementById('Witamy__nazwa_gracza').innerHTML = 'Witamy "..getPlayerName(localPlayer).."!';")
      executeBrowserJavascript(source, "document.getElementById('bank').innerHTML = 'Loading...';") -- display a placeholder while we're waiting for the server to return the balance
    end
  )
-- ...

-- this should be at top level scope, outside any functions
addEvent("bank-hajs-balans", true)
addEventHandler("bank-hajs-balans", localPlayer, -- server triggers this event sending over the balance
  function(bank)
    if initBrowser then -- we only want to continue if the player hasn't hid the panel in the meantime
      local theBrowser = guiGetBrowser(initBrowser)
      executeBrowserJavascript(theBrowser, "document.getElementById('bank').innerHTML = '$"..tostring(bank).."';") -- update player's displayed balance
    end
  end
)

The server should look like this:

function bank()
  local konto = getPlayerAccount(client) -- account of the client who sent the event to the server
  if konto then
    triggerClientEvent(client, "bank-hajs-balans", client, getAccountData(konto, "bank.balance"))
  end  
end
addEvent("bank-hajs-panel", true)
addEventHandler("bank-hajs-panel", root, bank)
