+<p><span class="seoSummary">Właściwość <code><strong>dataset</strong></code> interfejsu {{domxref("HTMLElement")}} pozwala na odczyt/zapis <a href="/en/HTML/Global_attributes#attr-data-*" title="https://developer.mozilla.org/en/HTML/Global_attributes#attr-data-*">niestandardowcyh atrybutów</a> (<code>data-*</code>) elementu.</span> Dostęp ten jest możliwy w HTMLu jak i w DOMie.  It is a <a href="/en/DOM/DOMStringMap" title="en/DOM/DOMStringMap">map of DOMString</a>, one entry for each custom data attribute. Zauważ że właściwość<strong> </strong><code>dataset</code><strong> </strong>można odczytać, ale nie zmieniać bezpośrednio. Zamiast tego, wszystkie zapisy muszą być wykonywane na pojedynczych polach <code>dataset</code>, które odpowiadają atrybutom danych. Note also that an HTML <code><strong>data-</strong></code><em>attribute</em> and its corresponding DOM<strong> </strong><code>dataset.</code><em>property</em> do not share the same name, but they are always similar:</p>
+
+<ul>
+ <li>The name of a custom data attribute in HTML begins with <code>data-</code>. It must contain only letters, numbers and the following characters: dash (<code>-</code>), dot (<code>.</code>), colon (<code>:</code>), underscore (<code>_</code>) -- but NOT any ASCII capital letters (<code>A</code> to <code>Z</code>).</li>
+ <li>The name of a custom data attribute in JavaScript is the name of the same HTML attribute but in camelCase and with no dashes, dots, etc.</li>
+</ul>
+
+<p>In addition to the information below, you'll find a how-to guide for using HTML data attributes in our article <a href="/en-US/docs/Learn/HTML/Howto/Use_data_attributes">Using data attributes.</a></p>
+
+<h3 id="Zmiana_nazw">Zmiana nazw</h3>
+
+<p>dash-style to camelCase: A custom data attribute name is transformed to a key for the {{ domxref("DOMStringMap") }} entry with the following rules</p>
+
+<ul>
+ <li>the prefix <code>data-</code> is removed (including the dash);</li>
+ <li>for any dash (<code>U+002D</code>) followed by an<span style="line-height: 1.5;"> ASCII lowercase letter </span><code>a</code><span style="line-height: 1.5;"> to </span><code>z</code><span style="line-height: 1.5;">, the dash is removed and the letter is transformed into its uppercase counterpart;</span></li>
+ <li>other characters (including other dashes) are left unchanged.</li>
+</ul>
+
+<p>camelCase to dash-style: The opposite transformation, that maps a key to an attribute name, uses the following rules:</p>
+
+<ul>
+ <li>Restriction: A dash must not be immediately followed by an ASCII lowercase letter <code>a</code> to <code>z</code> (before the transformation);</li>
+ <li>a prefix <code>data-</code> is added;</li>
+ <li>any ASCII uppercase letter <code>A</code> to <code>Z</code> is transformed into a dash followed by its lowercase counterpart;</li>
+ <li>other characters are left unchanged.</li>
+</ul>
+
+<p>The restriction in the rules above ensures that the two transformations are the inverse one of the other.</p>
+
+<p>For example, the attribute named <code>data-abc-def</code> corresponds to the key <code>abcDef</code>.</p>
+
+<ul>
+</ul>
+
+<h3 id="Dostęp_do_wartości">Dostęp do wartości</h3>
+
+<ul>
+ <li>Attributes can be set and read by using the camelCase name (the key) like an object property of the dataset, as in <em>element.</em>dataset.<em>keyname</em></li>
+ <li>Attributes can also be set and read using the object-properties bracket-syntax, as in <em>element.</em>dataset[<em>keyname</em>]</li>
+ <li>The <a href="/en-US/docs/Web/JavaScript/Reference/Operators/in">in operator</a> can be used to check whether a given atttribute exists.</li>
+</ul>
+
+
+
+<h3 id="Ustawianie_wartości">Ustawianie wartości</h3>
+
+<ul>
+ <li>Podawana podczas ustawiania atrybutu wartość jest zawsze zapisywana jako łańcuch znaków, np. <code>null</code> jest zapisywane jako "null".</li>
+ <li>Usunięcie atrybutu jest możliwe przy pomocy <a href="/en-US/docs/Web/JavaScript/Reference/Operators/delete">operatora delete</a>.</li>
