如何使用jquery ajax解析第二層JSON數組

Question

嗨下面是二級json數組解析的代碼。一級json輸出我能夠獲取。第二級我不能。即下CategoryImage我有兩個屬性，我可以不能夠獲取任何人都可以在this.Thanks幫助

<script>   
     $(document).ready(function() { 
      var cat=""; 
      categories(cat); 
      $('ul li').click(function(){ 
       var cat = $(this).text();    
       categories(cat);    
      }); 
     }); 
     function categories(cat){     
      $.ajax({ 
        url: "http://devcda.bryant.com/bryant/en/us/CommonSearchHandler.ashx?type=17&blogcategories="+cat,         dataType: "text",     
        success: function(data) {       
         var json = $.parseJSON(data); 
         var e=""; 
         $(".blog_desc").remove(); 
         for(var i in json.ResultPayload){ 


          e+="<div class='blog_desc'>"; 
          e+="<div class='tmpstr_hdr_cntnt container'>"; 
          e+=" <div class='col-lg-9 col-md-10 col-sm-10 col-xs-12'>" ; 
          e+="<h3>"+json.ResultPayload[i].DisplayTitle+"</h3>"; 
          e+="<p><span class='date_blg'>"+json.ResultPayload[i].CreationDate+"</span>Categories: <span class='cat_blg'>"+json.ResultPayload[i].BlogCategories+"</span></p>";       
          e+="<div class='col-lg-3 col-md-3 col-sm-3 col-xs-12'><img src="+json.ResultPayload[i].CategoryImage[i].Path+" class='img-responsive'> </div>"; 

          e+="<div class='col-lg-9 col-md-9 col-sm-9 col-xs-12'><p>"+json.ResultPayload[i].LongDescription+"</p>"; 
          e+="<p class='read_more'><a href="+json.ResultPayload[i].PageURL+">READ MORE</a></p>"; 
          e+="</div>";       
          e+="</div>"; 
          e+="</div>"; 
          e+="</div>"; 
          } 


         $("input").after(e); 

        } 
       }); 


     } 

    </script>

Answer 1

CategoryImage不是一個數組，以便ResultPayload [I] .CategoryImage.Path應該可以工作
