錯誤與解析嵌套的JSON結果

Question

我有以下的JSON的結果，在這裏我試圖提取description和title的價值，並試圖將其綁定到HTML佔位符，但我得到一個錯誤，而解析JSON說遺漏的類型錯誤：無法讀取未定義

jQuery代碼的特性 '長度'：

$.each(data.values, function (index, value) { 
    $.each(value.updateContent, function (i, uc) { 
      $.each(uc.companyStatusUpdate, function (j, cs) { 
       $("#link").append('<li ><a href="#"> ' + cs.description + '</li>'); 
       $("#link").append('<li ><a href="#"> ' + cs.title + '</li>'); 
       $("#link").listview('refresh'); 
       console.log(uc); 
      }); 
    }); 
});

Answer 1

你description和title被嵌套在content，所以你需要做的：

$.each(data.values, function (index, value) { 
    $.each(value.updateContent.companyStatusUpdate, function (j, cs) { 
     $("#link").append('<li ><a href="#"> ' + cs.content.description + '</li>'); 
     $("#link").append('<li ><a href="#"> ' + cs.content.title + '</li>'); 
     $("#link").listview('refresh'); 
     console.log(uc); 
    }); 
});
