jQuery Ajax calls and the Html.AntiForgeryToken()

by

I use a simple js function like this

AddAntiForgeryToken = function(data) {
    data.__RequestVerificationToken = $('#__AjaxAntiForgeryForm input[name=__RequestVerificationToken]').val();
    return data;
};

Since every form on a page will have the same value for the token, just put something like this in your top-most master page

<%-- used for ajax in AddAntiForgeryToken() --%>
<form id="__AjaxAntiForgeryForm" action="#" method="post"><%= Html.AntiForgeryToken()%></form>

Then in your ajax call do (edited to match your second example)

$.ajax({
    type: "post",
    dataType: "html",
    url: $(this).attr("rel"),
    data: AddAntiForgeryToken({ id: parseInt($(this).attr("title")) }),
    success: function (response) {
        // ....
    }
});
