Use this format for ajax post format :

var jSon = JSON.stringify(javascriptObject);

Your Json Format will be like this : '{name: "' + name +'" }',

function ShowCurrentTime() {
    $.ajax({
        type: "POST",
        url: "Installningar.aspx/Updatera",
        data: jSon; 
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: OnSuccess,
        failure: function(response) {
            alert(response.d);
        }
    });
}
function OnSuccess(response) {
    alert(response.d);
}
