Ajax調用SyntaxError：JSON.parse：JSON數據的第1行第1列的數據意外結束

我正在嘗試使用jQuery進行ajax調用並使用Coldfusion 10設置會話變量。這是我收到的錯誤：
SyntaxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON dataAjax調用SyntaxError：JSON.parse：JSON數據的第1行第1列的數據意外結束

我俯瞰的東西嗎？

$('#ToolTables_processing_1').on('click', function() { 
    $.ajax({ 
     // the location of the CFC to run 
     url: "redirects/selectedrows.cfm", 
     // send a GET HTTP operation 
     type: "post", 
     // tell jQuery we're getting JSON back 
     dataType: "json", 
     // send the data to the CFC 
     data: $('#form').serialize(), 
     // this gets the data returned on success 
     success: function (data) { 
      console.log(data); 
      window.location = 'forms/exitinterviewpdf.cfm'; 
     }, 
     // this runs if an error 
     error: function (xhr, textStatus, errorThrown) { 
      // show error 
      console.log(errorThrown); 
     } 
    }); 
});

如果我拿出datatype: json我只是得到一個空字符串。

selectedrows.cfm

錯誤在那裏它打破

如果您在重定向/ selectedrows.cfm中硬編碼某些JSON作爲響應會發生什麼情況？看起來重定向/ selectedrows.cfm不會返回任何內容。你可以在selectedrows.cfm中發佈代碼嗎？ –

爲什麼使用.cfm頁面而不是.cfc？雖然技術上你可以發佈到一個.cfm腳本，但它使得它很難控制輸出，並且更容易無意中打破ajax調用，然後使用.cfc。 – Leigh

先嚐試1個表單字段。前嘗試張貼併發送selectedRowName = David首先。這樣，你可以縮小問題，如果它的表單值或問題可能是selectedrows.cfm頁 – Vlad

我通常調試l當做大數據集縮小了問題範圍。請嘗試示例代碼

正如其他建議也可以是某些畸形的JSON數據和你在的Application.cfc想通了一些代碼的問題。
