Объект Json не разобрался правильно

Question

У меня есть this page, где к низу вы можете нажать на различные категории, чтобы проанализировать логотипы соответствующих компаний. Последний элемент в массиве (логотип «Wesco») должен отображаться только в категории «Распространение», но отображается в нескольких категориях. Файл JSON гласит:

JQuery является:

$.getJSON('customers.json', function(data) { 
       for(var index in definedCategoryArray){ //cycle through categories array 
        for(var i=0; i<data.customers.length; i++){ //cycle through json data 
         if (definedCategoryArray[index]==true){//if the value in the array is true (item checked) 
          console.log(data.customers[i].customerName+ ' : ' + data.customers[i].category); 
           if(data.customers[i].category.indexOf(',') != -1) //if there is more than one category, detect the comma seperating them 
            categoriesPlural = data.customers[i].category.split(','); 
           else //there is only one category 
            categoriesPlural[0]=data.customers[i].category; 
           for (var y = 0; y<categoriesPlural.length; y++){ 
             //console.log(categoriesPlural[y]); 
             if(categoriesPlural[y] == index){ //match category (from definedCategoryArray index) to items in json object to parse 
              $('ul#customers').append('<li class="' +data.customers[i].customerName.replace(/\s+/g, '-') + '" id="'+data.customers[i].customerName.replace(/\s+/g, '-')+'"><a href="'+ data.customers[i].link +'" title="'+ data.customers[i].customerName +'" target="_blank"><img src="'+ data.customers[i].imageLink +'" alt="'+ data.customers[i].customerName +'" /></a></li>'); 
              checkDuplicates(data.customers[i].customerName.replace(/\s+/g, '-')); 
             } 
           } 
         } 
        } 
       } 
      }).fail(function() { console.log("error"); }); 

Answer 1

Когда есть несколько категорий вы назначаете categoriesPlural с совершенно новым набором элементов, но если есть только одна категория вы только изменяя первый элемент категорийPlural, поэтому все, что ранее было присвоено категориямPlural (кроме первого элемента), все равно будет.

Вместо categoriesPlural[0]=data.customers[i].category вы должны сделать categoriesPlural=[data.customers[i].category]

Answer 2

Вы не объявляя или сброс categoriesPlural. Когда есть только один элемент после .split(), вы вставляете этот один элемент в categoriesPlural[0], но categoriesPlural[1] затем сохранит свое значение с предыдущей итерации. Декларирование categoriesPlural в начале вашего цикла будет делать трюк:

for(var i=0; i<data.customers.length; i++) { 

    var categoriesPlural = [];
