<p>L'interface <code><strong>HTMLSelectElement</strong></code> représente un élément HTML {{HTMLElement("select")}}. Cet élément partage aussi toute les propriétés et méthodes des autres elements HTML via l'interface {{ domxref("HTMLElement") }}.</p>

<h2 id="Properties" name="Properties">Propriétés</h2>

<p><em>Cette interface hérite des propriétés de {{domxref("HTMLElement")}}, {{domxref("Element")}} et {{domxref("Node")}}.</em></p>

<dl>
 <dt>{{domxref("HTMLSelectElement.autofocus")}}</dt>
 <dd><em>Est un </em>{{jsxref("Boolean")}} qui reflète l'attribut HTML {{ htmlattrxref("autofocus", "select") }} : il indique si l'élément a le focus au chargement de la page (excepté si l'utilisateur le change, par exemple en cliquant sur un autre element). Uniquement les elément associé à un formulaire dans le document peuvent utiliser cet attribut. {{ gecko_minversion_inline("2.0") }}</dd>
</dl>

<dl>
 <dt>{{domxref("HTMLSelectElement.disabled")}}</dt>
 <dd>Est un {{jsxref("Boolean")}} qui reflète l'attribut HTML {{ htmlattrxref("disabled", "select") }} : il indique si l'élément est oui ou non desactivé. Si il est désactivé, l'élément n'accepte pas les clicks.</dd>
 <dt>{{domxref("HTMLSelectElement.form")}} {{readonlyInline}}</dt>
 <dd>Retourne un {{domxref("HTMLFormElement")}} représentant le formulaire associé a cet élément. Si cet élément est le fils d'un formulaire, alors cet attribut est l'ID de l'element form. Si l'élément n'est pas fils d'un formulaire, alors l'attribut peut-être l'ID de n'importe quel élément du même document.</dd>
 <dt>{{domxref("HTMLSelectElement.labels")}} {{readonlyInline}}</dt>
 <dd>Retourne une {{ domxref("NodeList") }} contenant la liste des labels associé avec l'éléments select.</dd>
 <dt>{{domxref("HTMLSelectElement.length")}}</dt>
 <dd>Est un <code>unsigned long</code> représentant le nombre d'élément {{ HTMLElement("option") }} dans cet element <code>select</code>.</dd>
 <dt>{{domxref("HTMLSelectElement.multiple")}}</dt>
 <dd>Est un {{jsxref("Boolean")}} représentant l'attribut HTML {{ htmlattrxref("multiple", "select") }}, qui indique si plusieurs items peuvent être choisis à la fois par l'utilisateur.</dd>
 <dt>{{domxref("HTMLSelectElement.name")}}</dt>
 <dd>Est une {{ domxref("DOMString") }} qui représente l'attribut HTML {{ htmlattrxref("name", "select") }}, contenant le nom de ce contrôle pour les serveurs et pour les fonctions de recherche dans le DOM.</dd>
 <dt>{{domxref("HTMLSelectElement.options")}} {{readonlyInline}}</dt>
 <dd>Returns a {{ domxref("HTMLOptionsCollection") }} containing the set of {{ HTMLElement("option") }} elements contained by this element.</dd>
 <dt>{{domxref("HTMLSelectElement.required")}}</dt>
 <dd>Is a {{jsxref("Boolean")}} that reflects the {{ htmlattrxref("required", "select") }} HTML attribute, which indicates whether the user is required to select a value before submitting the form. {{ gecko_minversion_inline("2.0") }}</dd>
 <dt>{{domxref("HTMLSelectElement.selectedIndex")}}</dt>
 <dd>Is a <code>long</code> that reflects the index of the first selected {{ HTMLElement("option") }} element. The value <code>-1</code> indicates no element is selected.</dd>
 <dt>{{domxref("HTMLSelectElement.selectedOptions")}} {{readonlyInline}}</dt>
 <dd>Returns a live {{ domxref("HTMLCollection") }} containing the set of options that are selected.</dd>
 <dt>{{domxref("HTMLSelectElement.size")}}</dt>
 <dd>Is a <code>long</code> that reflects the {{ htmlattrxref("size", "select") }} HTML attribute, which contains the number of visible items in the control. The default is 1, unless <code>multiple</code> is true, in which case it is 4.</dd>
 <dt>{{domxref("HTMLSelectElement.type")}} {{readonlyInline}}</dt>
 <dd>Returns a {{ domxref("DOMString") }} the form control's type. When <code>multiple</code> is <code>true</code>, it returns <code>"select-multiple"</code>; otherwise, it returns <code>"select-one"</code>.</dd>
 <dt>{{domxref("HTMLSelectElement.validationMessage")}} {{readonlyInline}}</dt>
 <dd>Returns a {{ domxref("DOMString") }} containing a localized message that describes the validation constraints that the control does not satisfy (if any). This attribute is the empty string if the control is not a candidate for constraint validation (<code>willValidate</code> is false), or it satisfies its constraints.</dd>
 <dt>{{domxref("HTMLSelectElement.validity")}} {{readonlyInline}}</dt>
 <dd>Returns a {{domxref("ValidityState")}} representing the validity state that this control is in.</dd>
 <dt>{{domxref("HTMLSelectElement.value")}}</dt>
 <dd>Is a {{ domxref("DOMString") }} with the value of this form control, that is, of the first selected option.</dd>
 <dt>{{domxref("HTMLSelectElement.willValidate")}}{{readonlyInline}}</dt>
 <dd>Is a {{jsxref("Boolean")}} that indicates whether the button is a candidate for constraint validation. It is false if any conditions bar it from constraint validation.</dd>
</dl>

<h2 id="Methods" name="Methods">Méthodes</h2>

<p><em>This interface inherits the methods of {{domxref("HTMLElement")}}, and of {{domxref("Element")}} and {{domxref("Node")}}.</em></p>

<dl>
 <dt>{{domxref("HTMLSelectElement.add()")}}</dt>
 <dd>Adds an element to the collection of <code>option</code> elements for this <code>select</code> element.</dd>
 <dt>{{domxref("HTMLElement.blur", "HTMLSelectElement.blur()")}} {{ obsolete_inline}}</dt>
 <dd>Removes input focus from this element. <em>This method is now implemented on {{domxref("HTMLElement")}}</em>.</dd>
 <dt>{{domxref("HTMLSelectElement.checkValidity()")}}</dt>
 <dd>Checks whether the element has any constraints and whether it satisfies them. If the element fails its constraints, the browser fires a cancelable {{event("invalid")}} event at the element (and returns <code>false</code>).</dd>
 <dt>{{domxref("HTMLElement.focus", "HTMLSelectElement.focus()")}} {{obsolete_inline}}</dt>
 <dd>Gives input focus to this element. <em>This method is now implemented on {{domxref("HTMLElement")}}</em>.</dd>
 <dt>{{domxref("HTMLSelectElement.item()")}}</dt>
 <dd>Gets an item from the options collection for this {{HTMLElement("select")}} element. You can also access an item by specifying the index in array-style brackets or parentheses, without calling this method explicitly.</dd>
 <dt>{{domxref("HTMLSelectElement.namedItem()")}}</dt>
 <dd>Gets the item in the options collection with the specified name. The name string can match either the <code>id</code> or the <code>name</code> attribute of an option node. You can also access an item by specifying the name in array-style brackets or parentheses, without calling this method explicitly.</dd>
 <dt>{{domxref("HTMLSelectElement.remove()")}}</dt>
 <dd>Removes the element at the specified index from the options collection for this select element.</dd>
 <dt>{{domxref("HTMLSelectElement.setCustomValidity()")}}</dt>
 <dd>Sets the custom validity message for the selection element to the specified message. Use the empty string to indicate that the element does <em>not</em> have a custom validity error.</dd>
