Specifically, when a form has <code>autocomplete</code> set to <code>off</code> and its <code><input></code> element's <code>autocomplete</code> attribute is not set, then if the user asks for autofill suggestions for the <code><input></code> element, Samsung Internet might display a message saying 'autocomplete has been disabled for this form.' On the other hand, if both the form and the input element have <code>autocomplete</code> set to <code>off</code>, the browser will not display that message. For this reason, you should set <code>autocomplete</code> to <code>off</code> for each <code><input></code> that has custom auto-completion.</details></td> +</tr> +<tr> +<th><code>enctype</code></th> +<td class="bc-supports-yes">1</td> +<td class="bc-supports-yes">12</td> +<td class="bc-supports-yes">1</td> +<td class="bc-supports-yes">Yes</td> +<td class="bc-supports-yes">15</td> +<td class="bc-supports-yes">3</td> +<td class="bc-supports-yes">4.4</td> +<td class="bc-supports-yes">18</td> +<td class="bc-supports-yes">4</td> +<td class="bc-supports-yes">14</td> +<td class="bc-supports-yes">2</td> +<td class="bc-supports-yes">1.0</td> +</tr> +<tr> +<th><code>method</code></th> +<td class="bc-supports-yes">1</td> +<td class="bc-supports-yes">12</td> +<td class="bc-supports-yes">1</td> +<td class="bc-supports-yes">Yes</td> +<td class="bc-supports-yes">15</td> +<td class="bc-supports-yes">3</td> +<td class="bc-supports-yes">4.4</td> +<td class="bc-supports-yes">18</td> +<td class="bc-supports-yes">4</td> +<td class="bc-supports-yes">14</td> +<td class="bc-supports-yes">2</td> +<td class="bc-supports-yes">1.0</td> +</tr> +<tr> +<th><code>name</code></th> +<td class="bc-supports-yes">1</td> +<td class="bc-supports-yes">12</td> +<td class="bc-supports-yes">1</td> +<td class="bc-supports-yes">Yes</td> +<td class="bc-supports-yes">15</td> +<td class="bc-supports-yes">3</td> +<td class="bc-supports-yes">4.4</td> +<td class="bc-supports-yes">18</td> +<td class="bc-supports-yes">4</td> +<td class="bc-supports-yes">14</td> +<td class="bc-supports-yes">2</td> +<td class="bc-supports-yes">1.0</td> +</tr> +<tr> +<th><code>novalidate</code></th> +<td class="bc-supports-yes">10</td> +<td class="bc-supports-yes">12</td> +<td class="bc-supports-yes">4</td> +<td class="bc-supports-yes">10</td> +<td class="bc-supports-yes">15</td> +<td class="bc-supports-yes">10.1</td> +<td class="bc-supports-yes">37</td> +<td class="bc-supports-yes">18</td> +<td class="bc-supports-yes">4</td> +<td class="bc-supports-yes">14</td> +<td class="bc-supports-yes">10.3</td> +<td class="bc-supports-yes">1.0</td> +</tr> +<tr> +<th><code>rel</code></th> +<td class="bc-supports-yes">108</td> +<td class="bc-supports-yes">108</td> +<td class="bc-supports-yes">111</td> +<td class="bc-supports-no">No</td> +<td class="bc-supports-yes">94</td> +<td class="bc-supports-yes">15.4</td> +<td class="bc-supports-yes">108</td> +<td class="bc-supports-yes">108</td> +<td class="bc-supports-yes">111</td> +<td class="bc-supports-yes">73</td> +<td class="bc-supports-yes">15.4</td> +<td class="bc-supports-yes">21.0</td> +</tr> +<tr> +<th><code>target</code></th> +<td class="bc-supports-yes">1</td> +<td class="bc-supports-yes">12</td> +<td class="bc-supports-yes">1</td> +<td class="bc-supports-yes">Yes</td> +<td class="bc-supports-yes">15</td> +<td class="bc-supports-yes">3</td> +<td class="bc-supports-yes">4.4</td> +<td class="bc-supports-yes">18</td> +<td class="bc-supports-yes">4</td> +<td class="bc-supports-yes">14</td> +<td class="bc-supports-yes">2</td> +<td class="bc-supports-yes">1.0</td> +</tr> +</tbody> +</table></div> +<h2 id="see_also">See also</h2> +<div class="section-content"><ul> <li><a href="https://developer.mozilla.org/en-US/docs/Learn/Forms">HTML forms guide</a></li> <li>Other elements that are used when creating forms: <a href="button"><code><button></code></a>, <a href="datalist"><code><datalist></code></a>, <a href="fieldset"><code><fieldset></code></a>, <a href="input"><code><input></code></a>, <a href="label"><code><label></code></a>, <a href="legend"><code><legend></code></a>, <a href="meter"><code><meter></code></a>, <a href="optgroup"><code><optgroup></code></a>, <a href="option"><code><option></code></a>, <a href="output"><code><output></code></a>, <a href="progress"><code><progress></code></a>, <a href="select"><code><select></code></a>, <a href="textarea"><code><textarea></code></a>.</li> <li>Getting a list of the elements in the form: <a href="https://developer.mozilla.org/en-US/docs/Web/API/HTMLFormElement/elements"><code>HTMLFormElement.elements</code></a> +</li> <li><a href="https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/form_role">ARIA: Form role</a></li> <li><a href="https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/search_role">ARIA: Search role</a></li> </ul></div><div class="_attribution"> + <p class="_attribution-p"> + © 2005–2023 MDN contributors.<br>Licensed under the Creative Commons Attribution-ShareAlike License v2.5 or later.<br> + <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/form" class="_attribution-link">https://developer.mozilla.org/en-US/docs/Web/HTML/Element/form</a> + </p> +</div> |
