$ .ajax和$ .post在Chrome中工作

Question

I've tried both $.ajax & $.post and both are not working in Safari or Firefox. Oddly enough, they are working in Chrome. The 'savemarkup.php' call works fine but the 'sendemail.php' is throwing an error (which comes back to my console as an object). The 'sendemail.php' utilizes PhpMailer to send an email based on selections made in the program.

function generatePDF () {
$("#saving").css("display","none");
var email = generateEmail();
var markup = document.documentElement.innerHTML;
$.post (
'savemarkup.php', {
    markup: markup,
    email: email
},
function (data,status) {
    if (status === 'success') {
        $("#saving").fadeIn("fast");
        //$.post('sendemail.php');
        $.ajax({
            url: 'sendemail.php',
            type: 'POST',
            success: function(res) { 
                console.log( res ); 
            }, 
            error: function (xhr) { 
                console.log( xhr ); 
            }
        });
        var saveDelay = 1000;
        if (i > 3) {
            saveDelay = 333 * i;
        }
        $("#saving-image").attr("src","http://quote.hekmancontract.com/images/please-wait-pdf.gif");
        window.location = 'savepdf.php';
        $("#saving").delay(saveDelay).fadeOut("fast");
        $("#saving-image").attr("src","http://quote.hekmancontract.com/images/please-wait-saving.gif");
    }
});
}

I can't copy and paste the error log very easily so I've included a snapshot.
