what do mean "window.parent.document.forms"

is there a way to know what do mean without have rest of the code?

alert('Aviso!');
window.parent.document.forms[0].edAlgo.select();
window.parent.document.forms[0].edAlgo.focus();

    Correct answer WolfShade

    This is a JavaScript question, not a ColdFusion question, but I will attempt to answer it, anyway.

    window = self.

    parent = self is a child window, so parent is the window that spawned self.

    document = document object model (your code).

    forms[0] = first form in an array of forms.

    window.parent.document.forms[0] = opening (parent) window form.

    .adAlgo.select() = select form element "adAlgo".

    .adAlgo.focus() = place cursor in/on (focus) form element "adAlgo".

    It looks like it's part of form validation; if something in adAlgo is not correct, place the cursor there so the user knows that the value needs to be corrected.

    This is a complete guess, of course.

    HTH,

      Your English is not horrible; I think I understand what you are saying and asking.  Have you thought of using a mechanical translator, like translate.google.com?  (??????.google.br??)

      If by 'scatterbrained' you mean 'new to coding' - we all have to start somewhere, yes?

      Glad to help you to understand the code you supplied.  

      Seu Inglês não é horrível; Eu acho que entendo o que você está dizendo e fazendo. 
      Você já pensou em usar um tradutor mecânico, como translator.google.com? (??????. Google.br ??)

      Se por "desmiolada" quer dizer "novo para codificação '- todos nós temos que começar em algum lugar, certo?

      Fico feliz em ajudá-lo a entender o código fornecido. 

      V/r,

      ^_^
