How to show and hide elements based on HTML data attributes

HTML file:

<div class="test" data-word="AAA" data-type="T" data-number="1"> Text 1 </div>
<div class="test" data-word="AAA" data-type="BBB" data-number="2"> Text 2 </div>
<div class="test" data-word="AAA" data-type="CCC" data-number="2"> Text 3 </div>
<div class="test" data-word="D" data-type="BBB" data-number="6"> Text 4 </div>
<div class="test" data-word="AAA" data-type="BBB" data-number="2"> Text 6 </div>
<div class="test" data-word="G" data-type="R" data-number="5"> Text 7 </div>
<div class="test" data-word="H" data-type="BBB" data-number="1"> Text 5 </div>
<div class="test" data-word="AAA" data-type="R" data-number="9"> Text 8 </div>

I need to hide and show elements based on the attributes. Say I need to show elements with word AAA and type BBB and number 2. All the elements that have these attributes must be shown and others should be hidden using hide and show methods. Help?

$(function() {
  $(".test").each(function() {
    var d = $(this).data();
    $(this).toggle(d.word === "AAA" && d.type === "BBB" && d.number === 2);
  });
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="test" data-word="AAA" data-type="T" data-number="1">Text 1</div>
<div class="test" data-word="AAA" data-type="BBB" data-number="2">Text 2</div>
<div class="test" data-word="AAA" data-type="CCC" data-number="2">Text 3</div>
<div class="test" data-word="D" data-type="BBB" data-number="6">Text 4</div>
<div class="test" data-word="AAA" data-type="BBB" data-number="2">Text 6</div>
<div class="test" data-word="G" data-type="R" data-number="5">Text 7</div>
<div class="test" data-word="H" data-type="BBB" data-number="1">Text 5</div>
<div class="test" data-word="AAA" data-type="R" data-number="9">Text 8</div>

You could do this just based on selectors. For a more code-friendly approach use a filter function and read the data using jQuery data function. Start with the elements hidden and show the filtered results.

$('div.test').hide().filter(function(){
    var d = $(this).data();
    return d.word == 'AAA' && d.type == 'BBB' && d.number === 2;
}).show();

$('form')
    .children().data( { word: [ 'AAA','BBB' ], number: [2] } ).show();

You can select the elements using the attribute equals selector:

$('.test').hide().filter('[data-word="AAA"][data-type="BBB"][data-number="2"]').show();

First hide all, then filter and show necessary. Check the demo below.

$('.test').hide().filter('[data-word="AAA"][data-type="BBB"][data-number="2"]').show();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="test" data-word="AAA" data-type="T" data-number="1"> Text 1 </div>
<div class="test" data-word="AAA" data-type="BBB" data-number="2"> Text 2 </div>
<div class="test" data-word="AAA" data-type="CCC" data-number="2"> Text 3 </div>
<div class="test" data-word="D" data-type="BBB" data-number="6"> Text 4 </div>
<div class="test" data-word="AAA" data-type="BBB" data-number="2"> Text 6 </div>
<div class="test" data-word="G" data-type="R" data-number="5"> Text 7 </div>
<div class="test" data-word="H" data-type="BBB" data-number="1"> Text 5 </div>
<div class="test" data-word="AAA" data-type="R" data-number="9"> Text 8 </div>

try 

$(".test").data("data-word")

to get the value you need and put on the logic
