jsonデータをフィルタリングしてhtmlページに表示するには？

var filtered_value = $(this).attr("filterset"); 
    var filter_attribute = $(this).parent().parent().attr('data-facet'); 
    var count = 0; 
    var filtered_json = []; 
    $.getJSON('<?php echo $jsonFileUrl;?>', function (json) { 
     for (var i = 0; i < json.length; i++) { 
      if(json[i][filter_attribute] == filtered_value){ 
       count++; 
       filtered_json.push(json[i]); 
      } 
     } 
     //console.log(filtered_json); 
     var filterList = $.parseJSON(filtered_json); 
     console.log(filterList);return false; 
     var html = ''; 
     for (x in filterList) { 
      html += '<li>' + filterList[x].name 
     } 
    });

私の商品リストページにこのコードがあります。そして、私はjsonファイルから製品を入手しています。今私はサイズ、色、価格に基づいてこの製品をフィルタリングしたい。ビルドされたjsonデータをビルドに使用するにはどうすればよいですか？私はコンソールにnull値を取得しています:(jsonデータをフィルタリングしてhtmlページに表示するには？

あなたのHTMLも教えていただけますか？したがって、製品の構造がどのように見えるかを見ることができます –

jsonは製品の配列ですか？もしそうなら、あなたはArray.filter（）関数を得ることができます。これは、チェックに合格する製品の配列を返します。その後、フィルタリングされた配列から製品のプロパティを埋め込むようにHTMLを構築するだけです。 – patrykf

これは完全なプラグインです。 Jsonに基づいて要素を作成できます。役に立つと願っています。幸運 –

これらのケースでさらに説明が必要ですか？ –

これは動作します：

JavaScriptバージョン -

function tree(data) {  
    if (typeof(data) == 'object') { 
     document.write('<ul>'); 
     for (var i in data) { 
      document.write('<li>' + i); 
      tree(data[i]);    
     } 
     document.write('</ul>'); 
    } else { 
     document.write(' => ' + data); 
    } 
}

jQueryのバージョン -

を？

function tree(data) {  
    if (typeof(data) == 'object') {   
     var ul = $('<ul>'); 
     for (var i in data) {    
      ul.append($('<li>').text(i).append(tree(data[i])));   
     }   
     return ul; 
    } else {  
     var textNode = document.createTextNode(' => ' + data); 
     return textNode; 
    } 
} 

$(document.body).append(tree(data));
