Javascript Json无法正常工作

Question

I've tried it, but I haven't found a solution.

$(document).ready(function(){
$.ajax({
 url: 'https://api.firsatbufirsat.com/deal/browse.html?apiKey=FZTGT8NK3RTC5M2O&publisherId=609&cityId=42',
    type: 'get',
    dataType: "jsonp",
    success: function(data){  
        if(data){document.write(data.deals[0].title)}
    }

});
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Why doesn't this work?

</div>
