For display an alert for remind user to help me run this page

// Need jQuery
// dataType and crossDomain for ignore CORS
// In case of loading adsbygoogle.js success, it still throw error related to the callback. That's why I only catch the 404 error

$.ajax({
    type: "HEAD", url: "https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js",
    dataType: 'jsonp',
    crossDomain: true,
    success: function (data, text) {
        // skip
    },
    error: function (request, status, error) {
        if(request.status==404)
            alert("Please disable adblock, it helps me running this blog :)");
    }
});
