How do I fill a field of a page in Curl and this does not send the data via form, but via Javascript?

The page in question is this:

<script type='text/javascript' src='js/juridico.js'></script>
<script type='text/javascript' src='dwr/engine.js'></script>
<script type='text/javascript' src='dwr/util.js'></script>
<script type='text/javascript' src='dwr/interface/ValidacaoCaptchaAction.js'></script>


<!-- Início do include do captcha para qualquer página -->
<script type="text/javascript" language="Javascript1.1">

    var popup = true;

    if (window.dialogArguments) { // IE
        window.opener = window.dialogArguments;
    }

    window.onload = load;

    window.onbeforeunload = unload;

    function validaNumeroCaptcha(e){

        var unicode=e.charCode? e.charCode : e.keyCode;
        if (unicode!=8){ //if the key isn't the backspace key (which we should allow)(127=DEL Key)
            if (unicode<48||unicode>57) //if not a number
                return false; //disable key press
        }
        document.getElementById("mensagem").innerHTML = "&nbsp;";

        return true;

    }

    function setTextoCaptchaFocus(){
        document.getElementById('captcha_text').focus();

    }
    function recarregaImagem(){
        document.getElementById('captcha_image').src = "imagens/icon_wait.gif";

When you have forms processing just use CURLOPT_POSTFIELDS, but in this case you do not have, how to proceed?

php javascript jquery curl captcha

  • I don’t understand what you want to do, this page does not submit or request any data... it is just a captcha field?

  • The page in question is this: www4.tjmg.jus.br/juridico/sf/captcha.jsp In the case after typing the correct captcha the page is in eternal "loop", but allows me to view the query pages without having to type another captcha. Try to access this link anonymously: http://www4.tjmg.jus.br/juridico/sf/proc_resultado_nome.jsp?nomePessoa=NOME_DA_PESSSOA&cpfcnpj=&tipPessoa=X&naturezProcesso=1&situacaoParteA&comCodigo=NUMERO_DA_COMARCA&numero=1 Go ask captcha. Now access the first link of this reply, type the captcha and then access this second, will access normally.

  • Managed to understand @Luishenrique ?

  • Which Curl you already have, nothing?

  • @Inkeliz includes the following files: http://answall.com/questions/114152/tjmg-fazer-busca-em-loop-entre-comarcas-com-curl-e-captcha
