Cara use JQuery é muito simples olhe :
//in cs
[WebMethod]
public static string Teste(string param)
{
return param;
}
No aspx :
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script>
<head runat="server">
<script type="text/javascript">
$(document).ready(function () {
$('#<%=Button1.ClientID %>').click(function () {
$.ajax({
type: "POST",
url: "Default1.aspx/Teste",
data: "{'param' : 'TESTE'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
cache: false,
success: function (msg) {
alert(msg.d);
}
})
return false;
});
});
</script>
<title></title>
