jQuery.ajax不發送一個XMLHttpRequest頭

Question

使用1.7.2，我提交使用jQuery.ajax（）形式：）

jQuery.ajax({ 
    url: form.attr('action'), 
    action: 'POST', 
    dataType: 'json', 
    data: {post_id: id}, 
    success: function(data) { 
     console.log('hurrah!'); 
    }, 
    error: function() { 
     console.log('whoops'); 
    } 
}); 

我期待的阿賈克斯（呼叫設置了XMLHttpRequest頭，但它不是：

Referer: http://0.0.0.0:5000/messages/news-feed 
Origin: http://0.0.0.0:5000 
Content-Length: 42 
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/535.18.5 (KHTML, like Gecko) Version/5.2 Safari/535.18.5 
Connection: keep-alive 
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 
Accept-Language: en-us 
Content-Type: application/x-www-form-urlencoded 
Accept-Encoding: gzip, deflate 

我試着加入headers設置的號召，但它沒有做任何區別;頭沒有被設置："X-Requested-With":"XMLHttpRequest"

我也試過

beforeSend: function (request) { 
    request.setRequestHeader("X-Requested-With", "XMLHttpRequest"); 
} 

Answer 1

試試這個

$.ajax({ 
url: form.attr('action'), 
dataType:'json', 
type:'POST', 
success:function(data){ 
console.log(data); 
}, 
error:function(jxhr){ 
console.log(jxhr.responseText); 
} 

});
