I have a form in my jsp page, and I have to capture the POST variables when clicking ok button and print them.
I think my solution is Ajax,but I'm not able to get it.
<html>
<head>
<meta http-equiv="Content-Type" content="text/html"; charset="ISO-8859-1">
<title>Ejemplo de carga de datos</title>
<script src="/Scripts/jquery-1.9.1.js"></script>
<script>
$(function(){
$(document).ready(function () {
$('input[type="submit"]').click(function (event) {
var url = "datos.jsp"; // El script a dónde se realizará la petición.
$.ajax({
type: "POST",
url: url,
data: $("#form").serialize(), // Adjuntar los campos del formulario enviado.
success: function(data)
{
}
});
});
});
});
</script>
</head>
<body>
<form name="form" id="form" method="post" enctype="multipart/form-data" >
<textarea cols=50 rows=10 name="texto" id="texto"></textarea>
<input type="submit" name="submit" value="Enviar datos" />
</form>
</body>
</html>
And datos.jsp:
<%
String texto = request.getParameter(texto);
System.out.println(texto)
%>
But it doesnt work How can I do it?
I add @Aleksey Bykov's sugestion.

<meta http-equiv="Content-Type" content="text/html"; charset="ISO-8859-1">

<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
<script>
$(function(){
$(document).ready(function () {
$('input[type="submit"]').click(function (event) {
var textoVar = $('#texto').val();
alert(textoVar);
$.ajax({
url: 'page.jsp',
type: 'POST',
dataType: 'json',
data: {
texto: textoVar
},
success: function (data) {
//
},
failure: function (data) {
//
}
});
});
});
});
</script>
</head>
<body>
<span>Sent via AJAX: <b><c:out value="${param.texto}" /></b></span>
<form name="form" id="form" method="post" enctype="multipart/form-data" >
<textarea cols=50 rows=10 name="texto" id="texto"></textarea>
<input type="submit" name="submit" value="Enviar datos" />
</form>
</body>
It always prints ${param.texto} (this line not the value), even without send the form.
