<h2 id="Attributi">Attributi</h2>

<p>L'elemento <strong>&lt;iframe&gt; </strong>possiede i seguenti attributi.</p>

<dl>
 <dt>{{htmlattrdef("align")}} {{deprecated_inline("html4.01")}}, {{obsolete_inline("html5")}}</dt>
 <dd>L'allineamento dell'iframe rispetto al contesto circostante.</dd>
 <dt></dt>
 <dt>{{htmlattrdef("allowfullscreen")}}</dt>
 <dd>Se questo attributo è settato a <code>true</code> l'iframe puó essere collocato a schermo intero chiamando il metodo {{domxref("Element.requestFullscreen()")}}. Se non é settato l'iframe non puó collocari a schermo intero.</dd>
 <dt>{{htmlattrdef("frameborder")}} {{HTMLVersionInline(4)}} only</dt>
 <dd>Il valore 1 (default) dice al browser di disegnare un bordo tra l'iframe ed ogni altro iframe. Il valore - dice al browser di non disegnare un bordo tra l'iframe ed ogni altro iframe.</dd>
 <dt>{{htmlattrdef("height")}}</dt>
 <dd>Indica l'altezza dell'iframe {{HTMLVersionInline(5)}} in CSS pixels.</dd>
 <dt>{{htmlattrdef("longdesc")}} {{HTMLVersionInline(4)}} only</dt>
 <dd>Non é supportato in HTML5. É un URI di una descrizione del frame.</dd>
 <dt>{{htmlattrdef("marginheight")}} {{HTMLVersionInline(4)}} only</dt>
 <dd>Non é supportato in HTML5. É il margine superiore ed inferiore in pixel.</dd>
 <dt>{{htmlattrdef("marginwidth")}} {{HTMLVersionInline(4)}} only</dt>
 <dd>Non é supportato in HTML5. É il margine destro e sinistro in pixel.</dd>
 <dt>{{htmlattrdef("mozallowfullscreen")}} {{non-standard_inline}} {{deprecated_inline}}</dt>
 <dd>Usa <code><strong>allowfullscreen</strong></code> invece. Per Gecko 9.0 o superiori. Se questo attributo è settato a <code>true</code> l'iframe puó essere collocato a schermo intero chiamando il metodo {{domxref("Element.requestFullscreen()")}}. Se non é settato l'iframe non puó collocari a schermo intero.</dd>
 <dt>{{htmlattrdef("webkitallowfullscreen")}} {{non-standard_inline}} {{deprecated_inline}}</dt>
 <dd>Usa <code><strong>allowfullscreen</strong></code> invece. Per Chrome 17 o superiori. Se questo attributo è settato a <code>true</code> l'iframe puó essere collocato a schermo intero chiamando il metodo {{domxref("Element.requestFullscreen()")}}. Se non é settato l'iframe non puó collocari a schermo intero.</dd>
 <dt>{{htmlattrdef("mozapp")}} {{non-standard_inline}}</dt>
 <dd>Per iframe ospitati da <a href="/en-US/docs/Apps" title="OpenWebApps">open web app</a>, questo attributo specifica l'URL all' <a href="/en-US/docs/Apps/Manifest">app manifest</a>. Questo attributo assicura che l'iframe é visualizzato con i giusti permessi.</dd>
 <dt>{{htmlattrdef("mozbrowser")}} {{non-standard_inline}}</dt>
 <dd>Indica che l'iframe deve apparire come una pagina top-level. Questo significa che {{domxref("window.top")}}, {{domxref("window.parent")}}, {{domxref("window.frameElement")}}, etc. non rifletteranno la gerarchia dei frame.</dd>
 <dt id="name-attribute">{{htmlattrdef("name")}}</dt>
 <dd>Il nome dell' iframe.</dd>
 <dt id="attr-referrer">{{htmlattrdef("referrerpolicy")}} {{experimental_inline}}</dt>
 <dd>A string indicating which referrer to use when fetching the resource:
 <ul>
  <li><code>"no-referrer"</code> meaning that the <code>Referer:</code> header will not be sent.</li>
  <li>"<code>no-referrer-when-downgrade</code>" meaning that no <code>Referer:</code> header will be sent when navigating to an origin without TLS (HTTPS). This is a user agent’s default behavior, if no policy is otherwise specified.</li>
  <li><code>"origin"</code> meaning that the referrer will be the origin of the page, that is roughly the scheme, the host and the port.</li>
  <li>"origin-when-cross-origin" meaning that navigations to other origins will be limited to the scheme, the host and the port, while navigations on the same origin will include the referrer's path.</li>
  <li><code>"unsafe-url"</code> meaning that the referrer will include the origin and the path (but not the fragment, password, or username). This case is unsafe because it can leak origins and paths from TLS-protected resources to insecure origins.</li>
 </ul>
 </dd>
 <dt>{{htmlattrdef("remote")}} {{non-standard_inline}}</dt>
 <dd>Load the frame's page in a separate content process.</dd>
 <dt>{{htmlattrdef("scrolling")}} {{HTMLVersionInline(4)}} only</dt>
 <dd>Indica se l'iframe deve fornire una scroll bar. I valori sono:</dd>
 <dd>
 <ul>
  <li><code>auto</code>: solo quando necessario.</li>
  <li><code>yes</code>: fornisci sempre una scroll bar.</li>
  <li><code>no</code>: Non fornire mai una scroll bar.</li>
 </ul>
 </dd>
 <dt>{{htmlattrdef("sandbox")}} {{HTMLVersionInline(5)}} only</dt>
 <dd>If specified as an empty string, this attribute enables extra restrictions on the content that can appear in the inline frame. The value of the attribute can either be an empty string (all the restrictions are applied), or a space-separated list of tokens that lift particular restrictions. Valid tokens are:
 <ul>
  <li><code>allow-forms</code>: Allows the embedded browsing context to submit forms. If this keyword is not used, this operation is not allowed.</li>
  <li><code>allow-modals</code>: Allows the embedded browsing context to open modal windows.</li>
  <li><code>allow-orientation-lock</code>: Allows the embedded browsing context to disable the ability to lock the screen orientation.</li>
  <li><code>allow-pointer-lock</code>: Allows the embedded browsing context to use the <a href="/en-US/docs/WebAPI/Pointer_Lock">Pointer Lock API</a>.</li>
  <li><code>allow-popups</code>: Allows popups (like from <code>window.open</code>, <code>target="_blank"</code>, <code>showModalDialog</code>). If this keyword is not used, that functionality will silently fail.</li>
  <li><code>allow-popups-to-escape-sandbox</code>:  Allows a sandboxed document to open new windows without forcing the sandboxing flags upon them. This will allow, for example, a third-party advertisement to be safely sandboxed without forcing the same restrictions upon a landing page.</li>
  <li><code>allow-presentation</code>: Allows embedders to have control over whether an iframe can start a presentation session.</li>
  <li><code>allow-same-origin</code>: Allows the content to be treated as being from its normal origin. If this keyword is not used, the embedded content is treated as being from a unique origin.</li>
  <li><code>allow-scripts</code>: Allows the embedded browsing context to run scripts (but not create pop-up windows). If this keyword is not used, this operation is not allowed.</li>
  <li><code>allow-top-navigation</code>: Allows the embedded browsing context to navigate (load) content to the top-level browsing context. If this keyword is not used, this operation is not allowed.</li>
 </ul>

 <div class="note">
 <p><strong>Note:</strong></p>

 <ul>
  <li>When the embedded document has the same origin as the main page, it is strongly discouraged to use both <code>allow-scripts</code> and <code>allow-same-origin</code> at the same time, as that allows the embedded document to programmatically remove the <code>sandbox</code> attribute. Although it is accepted, this case is no more secure than not using the <code>sandbox</code> attribute.</li>
  <li>Sandboxing in general is only of minimal help if the attacker can arrange for the potentially hostile content to be displayed in the user's browser outside a sandboxed <code>iframe</code>. It is recommended that such content should be served from a <em>separate dedicated domain</em>, to limit the potential damage.</li>
  <li>The <code>sandbox</code> attribute is not supported in Internet Explorer 9 and earlier versions.</li>
 </ul>
 </div>
 </dd>
 <dt>{{htmlattrdef("src")}}</dt>
 <dd>L'URL della pagina da visualizzare all'interno dell'iframe.The URL of the page to embed. Usa <a href="/en-US/docs/Web/Security/Same-origin_policy#Inherited_origins">'about:blank'</a> per pagine vuote affinchè esse siano conformi a Same-Origin Policy.</dd>
 <dt>{{htmlattrdef("srcdoc")}} {{HTMLVersionInline(5)}} only</dt>
 <dd>The content of the page that the embedded context is to contain. This attribute is expected to generally be used together with the <code>sandbox</code> attribute. If a browser supports the <code>srcdoc</code> attribute, it will override the content specified in the <code>src</code> attribute (if present). If a browser does NOT support the <code>srcdoc</code> attribute, it will show the file specified in the <code>src</code> attribute instead (if present). Note that if the content of the attribute contains a script tag then a closing script tag is required for the script to run, even if nothing else comes after the script.</dd>
 <dt>{{htmlattrdef("width")}}</dt>
 <dd>Indica la larghezza del frame {{HTMLVersionInline(5)}} in CSS pixels, o {{HTMLVersionInline(4.01)}} in pixels o in percentuale.</dd>
</dl>

<h2 id="Scripting">Scripting</h2>

<p>Dal DOM gli script possono accedere all'oggetto {{domxref("window")}} dell'iframe attraverso la proprietà <code>contentDocument</code>. Non é supportato dalle versioni di Internet Explorer inferiori alla IE8.</p>

<p>Dall'iframe, uno script puó accedere alla window del parent attravero {{domxref("Window.parent")}}.</p>

<p>Per via della  <a href="/en-US/docs/Same_origin_policy_for_JavaScript" title="Same origin policy for JavaScript">same-origin policy</a>, gli script non posono accedere alle proprieta' degli altri oggetti window. Comunicazioni cross-domain possono sempre avvenire con {{domxref("Window.postMessage()")}}.</p>

<p>Di seguito alcuni esempi che dimostrano l'utilizzo dell'elemento <code>&lt;iframe&gt;</code>.</p>
