Troubleshooting anti-forgery token problems

Question

I have a form post that consistently gives me an anti-forgery token error.

Here is my form:

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()

You should prevent double form submission. I prevent this type of issue using code like this:

$('#loginForm').on('submit',function(e){
    var $form = $(this);

    if (!$form.data('submitted') && $form.valid()) {
      // mark it so that the next submit can be ignored
      $form.data('submitted', true);
      return;
    }

    // form is invalid or previously submitted - skip submit
    e.preventDefault();
});

or

$('#loginForm').submit(function () {
    $(this).find(':submit').attr('disabled', 'disabled'); 
});
