如何使用jquery ajax解析第二級JSON數組

Question

您好，下面是第二層json數組解析的代碼。 我可以提取第一級json輸出。 第二級，我不能。 即在CategoryImage下，我有兩個我無法獲取的屬性，任何人都可以對此提供幫助。

<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不是數組，因此ResultPayload [i] .CategoryImage.Path應該可以工作
