Wie json Daten filtern und auf HTML-Seite anzeigen?

Question

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 
     } 
    }); 

Ich habe diesen Code in meiner Produktliste Seite. Und ich bekomme Produkte von JSON-Datei. Jetzt möchte ich diese Produkte nach Größe, Farbe, Preis filtern. Wie kann ich gefilterte JSON-Daten zum Erstellen von li verwenden? ? Ich erhalte Nullwert in der Konsole :(

// external js: isotope.pkgd.js 
 

 
// init Isotope 
 
var $grid = $('.grid').isotope({ 
 
    itemSelector: '.element-item', 
 
    layoutMode: 'fitRows', 
 
    getSortData: { 
 
    name: '.name', 
 
    symbol: '.symbol', 
 
    number: '.number parseInt', 
 
    category: '[data-category]', 
 
    weight: function(itemElem) { 
 
     var weight = $(itemElem).find('.weight').text(); 
 
     return parseFloat(weight.replace(/[\(\)]/g, '')); 
 
    } 
 
    } 
 
}); 
 

 
// filter functions 
 
var filterFns = { 
 
    // show if number is greater than 50 
 
    numberGreaterThan50: function() { 
 
    var number = $(this).find('.number').text(); 
 
    return parseInt(number, 10) > 50; 
 
    }, 
 
    // show if name ends with -ium 
 
    ium: function() { 
 
    var name = $(this).find('.name').text(); 
 
    return name.match(/ium$/); 
 
    } 
 
}; 
 

 
// bind filter button click 
 
$('#filters').on('click', 'button', function() { 
 
    var filterValue = $(this).attr('data-filter'); 
 
    // use filterFn if matches value 
 
    filterValue = filterFns[ filterValue ] || filterValue; 
 
    $grid.isotope({ filter: filterValue }); 
 
}); 
 

 
// bind sort button click 
 
$('#sorts').on('click', 'button', function() { 
 
    var sortByValue = $(this).attr('data-sort-by'); 
 
    $grid.isotope({ sortBy: sortByValue }); 
 
}); 
 

 
// change is-checked class on buttons 
 
$('.button-group').each(function(i, buttonGroup) { 
 
    var $buttonGroup = $(buttonGroup); 
 
    $buttonGroup.on('click', 'button', function() { 
 
    $buttonGroup.find('.is-checked').removeClass('is-checked'); 
 
    $(this).addClass('is-checked');

Answer 2

Dies funktioniert:

Javascript-Version -

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-Version -

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));
