Sie können auf die Argumente einer Funktion innerhalb dieser Funktion mithilfe ihres <code>arguments</code> Objekts zugreifen. Es hat Einträge für jedes Argument, mit dem die Funktion aufgerufen wurde, wobei der Index des ersten Eintrags <code>0</code> ist.</p> <p>Zum Beispiel, wenn einer Funktion 3 Argumente übergeben werden, können Sie auf sie wie folgt zugreifen:</p> <div class="code-example"><div class="example-header"><span class="language-name">js</span></div><pre class="brush: js notranslate"><code>arguments[0]; // first argument arguments[1]; // second argument arguments[2]; // third argument </code></pre></div> <p>Das <code>arguments</code> Objekt ist nützlich für Funktionen, die mit mehr Argumenten aufgerufen werden, als sie formell akzeptieren, sogenannte <a href="https://en.wikipedia.org/wiki/Variadic_function" class="external" target="_blank"><em>variadic functions</em></a>, wie z.B. <a href="/de/docs/Web/JavaScript/Reference/Global_Objects/Math/min"><code>Math.min()</code></a>.

Das einzige formelle Argument für die Funktion ist eine Zeichenkette, die <code>\"u\"</code> ist, wenn die Liste <a href=\"/de/docs/Web/HTML/Element/ul\">ungeordnet (aufgezählt)</a> sein soll, oder <code>\"o\"</code>, wenn die Liste <a href=\"/de/docs/Web/HTML/Element/ol\">geordnet (nummeriert)</a> sein soll. Die Funktion ist wie folgt definiert:</p>\n<div class=\"code-example\"><div class=\"example-header\"><span class=\"language-name\">js</span></div><pre class=\"brush: js notranslate\"><code>function list(type) {\n let html = `<${type}l><li>`;\n const args = Array.prototype.slice.call(arguments, 1);\n html += args.join(\"</li><li>\");\n html += `</li></${type}l>`; // end list\n return html;\n}\n</code></pre></div>\n<p>Sie können dieser Funktion beliebig viele Argumente übergeben, und sie fügt jedes Argument als Listenelement zu einer Liste des angegebenen Typs hinzu. Zum Beispiel:</p>\n<div class=\"code-example\"><div class=\"example-header\"><span class=\"language-name\">js</span></div><pre class=\"brush: js notranslate\"><code>list(\"u\", \"One\", \"Two\", \"Three\");\n// \"<ul><li>One</li><li>Two</li><li>Three</li></ul>\"\n</code></pre></div>"}},{"type":"prose","value":{"id":"verwenden_von_typeof_mit_arguments","title":"Verwenden von typeof mit arguments","isH3":true,"content":"<p>Der <a href=\"/de/docs/Web/JavaScript/Reference/Operators/typeof\"><code>typeof</code></a> Operator gibt <code>'object'</code> zurück, wenn er mit <code>arguments</code> verwendet wird</p>\n<div class=\"code-example\"><div class=\"example-header\"><span class=\"language-name\">js</span></div><pre class=\"brush: js notranslate\"><code>console.log(typeof arguments); // 'object'\n</code></pre></div>\n<p>Der Typ einzelner Argumente kann durch Indizieren von <code>arguments</code> bestimmt werden:</p>\n<div class=\"code-example\"><div class=\"example-header\"><span class=\"language-name\">js</span></div><pre class=\"brush: js notranslate\"><code>console.log(typeof arguments[0]); // returns the type of the first argument\n</code></pre></div>"}},{"type":"specifications","value":{"title":"Spezifikationen","id":"spezifikationen","isH3":false,"specifications":[{"bcdSpecificationURL":"https://tc39.es/ecma262/multipage/ordinary-and-exotic-objects-behaviours.html#sec-arguments-exotic-objects","title":"ECMAScript Language Specification"}],"query":"javascript.functions.arguments"}},{"type":"browser_compatibility","value":{"title":"Browser-Kompatibilität","id":"browser-kompatibilität","isH3":false,"query":"javascript.functions.arguments"}},{"type":"prose","value":{"id":"siehe_auch","title":"Siehe auch","isH3":false,"content":"<ul>\n <li><a href=\"/de/docs/Web/JavaScript/Guide/Functions\">Funktionen</a> Leitfaden</li>\n <li><a href=\"/de/docs/Web/JavaScript/Reference/Functions\">Funktionen</a></li>\n <li><a href=\"/de/docs/Web/JavaScript/Reference/Functions/rest_parameters\">Rest-Parameter</a></li>\n</ul>"}}],"toc":[{"text":"Probieren Sie es aus","id":"probieren_sie_es_aus"},{"text":"Beschreibung","id":"beschreibung"},{"text":"Eigenschaften","id":"eigenschaften"},{"text":"Beispiele","id":"beispiele"},{"text":"Spezifikationen","id":"spezifikationen"},{"text":"Browser-Kompatibilität","id":"browser-kompatibilität"},{"text":"Siehe auch","id":"siehe_auch"}],"summary":"arguments ist ein array-ähnliches Objekt, das in Funktionen zugänglich ist und die Werte der an diese Funktion übergebenen Argumente enthält.","popularity":0,"modified":"2022-08-14T03:39:57.000Z","other_translations":[{"locale":"en-US","title":"The arguments object","native":"English (US)"},{"locale":"es","title":"El objeto arguments","native":"Español"},{"locale":"fr","title":"arguments","native":"Français"},{"locale":"ja","title":"arguments オブジェクト","native":"日本語"},{"locale":"ko","title":"arguments 객체","native":"한국어"},{"locale":"pt-BR","title":"Arguments object","native":"Português (do Brasil)"},{"locale":"ru","title":"Объект arguments","native":"Русский"},{"locale":"zh-CN","title":"Arguments 对象","native":"中文 (简体)"}],"pageType":"unknown","source":{"folder":"de/web/javascript/reference/functions/arguments","github_url":"https://github.com/mdn/translated-content/blob/main/files/de/web/javascript/reference/functions/arguments/index.md","last_commit_url":"https://github.com/mdn/translated-content/commit/aebcbfc2355fccddc193e6b25ba720935bf90172","filename":"index.md"},"short_title":"Das arguments Objekt","parents":[{"uri":"/de/docs/Web","title":"Web-Technologien für Entwickler"},{"uri":"/de/docs/Web/JavaScript","title":"JavaScript"},{"uri":"/de/docs/Web/JavaScript/Reference","title":"JavaScript-Referenz"},{"uri":"/de/docs/Web/JavaScript/Reference/Functions","title":"Functions"},{"uri":"/de/docs/Web/JavaScript/Reference/Functions/arguments","title":"Das arguments Objekt"}],"pageTitle":"Das arguments Objekt - JavaScript | MDN","noIndexing":false}}</script></body></html>
