阿賈克斯請求返回200好，但錯誤，而不是成功

Question

任何人都可以幫助我..

我有這個AJAX腳本調用一個XML頁面。

$.ajax({ 
    type: "GET", 
    url: "game/", 
    dataType: "xml", 
    data : { 
     g : 'new', 
     uid : uid 
    }, 

    error: function (xml) { 
    console.log("ERROR"); 
    console.log(xml); 

    alert(xml.status + ' ' + xml.statusText) 
    }, 


    success: function(xml) 
    { 
    ... 

    } 

但是我在錯誤對象中返回狀態：200 OK。爲什麼會發生？

在這裏，我我的控制檯日誌：

XML響應是：

Answer 1

好吧，這是XML解析問題。您收到的XML在第25行中有非轉義符號字符： <comment>Inde hos Joe & The Juice</comment>

要求客戶端escape it或將其更改爲文本。其餘的XML解析正確。

另外，請記住這樣的信息添加到您的問題下一次，它有很大幫助。 ;）

Answer 2

使用此類型的回調，看到正確的錯誤。

error: function (xhr, ajaxOptions, thrownError) { 
     console.log(xhr.status); 
     console.log(thrownError); 
     } 

然後通過設置適當的返回數據類型來修復。
