If you need to refresh the __RequestVerificationToken on your page, this is stored as a hidden input field but can be generated on demand by loading /_layout/tokenhtml.
In my case, I apply the token to a form posting to ensure the request is valid.
$("#antiforgerytoken").load("/_layout/tokenhtml", function() { console.log("tokenhtml loaded"); $("form>input[name='__RequestVerificationToken']").val($("div#antiforgerytoken>input[name='__RequestVerificationToken']").val()); });
