Hy everybody,
I'm making a website with html, javascript, jquery, and ajax techniques.
But when i'm sending an ajax request the page reloads!
Does anyone know why that is?
this is my ajax code:

$(document).ready(function(){
$("form").submit(function(){
	$.ajax({
		type:"POST",
		url:"ajax.php",
		data:"a="+$("#a").val()+"&distance="+$("#b").val()+"&c="+$("#c").val(),
		success: function(r){$("#result_wrapper").html(r)},
		error: function(){alert("error")}
	})
});
});

Tempestas Ludi.
