Revision 927581 of contextmenu

{{HTMLSidebar("Global_attributes")}}

<p>The <strong>contextmenu</strong> <a href="/en-US/docs/Web/HTML/Global_attributes">global attribute</a> is the <a href="/en-US/docs/Web/HTML/Global_attributes/id"><strong>id</strong></a> of an {{HTMLElement("menu")}} to us as the contextual menu for this element.</p>

<p>A <em>context menu</em> is a menu that appears upon user interaction, such as a right-click. HTML5 now allows us to customize this menu. Here are some implementation examples, including nested menus.</p>

<div id="ContextMenu_Example">
<h2 id="Example">Example</h2>

<p>The following HTML...</p>

<pre class="brush:html; highlight:[1,10,15]">
&lt;body contextmenu="share"&gt;
  &lt;menu type="context" id="share"&gt;
    &lt;menu label="share"&gt;
      &lt;menuitem label="Twitter" onclick="window.open('https://twitter.com/intent/tweet?text=Hurray! I am learning ContextMenu from MDN via Mozilla');"&gt;&lt;/menuitem&gt;
      &lt;menuitem label="Facebook" onclick="window.open('https://facebook.com/sharer/sharer.php?u=https://https://developer.mozilla.org/en/HTML/Element/Using_HTML_context_menus');"&gt;&lt;/menuitem&gt;
    &lt;/menu&gt;
  &lt;/menu&gt;
  &lt;ol&gt;
    &lt;li&gt;Anywhere in the example you can share the page on Twitter and Facebook using the Share menu from your context menu.&lt;/li&gt;
    &lt;li&gt;&lt;pre contextmenu="changeFont" id="fontSizing"&gt;On this specific list element, you can change the size of the text by using the "Increase/Decrease font" actions from your context menu&lt;/pre&gt;&lt;/li&gt;
    &lt;menu type="context" id="changeFont"&gt;
      &lt;menuitem label="Increase Font" onclick="incFont()"&gt;&lt;/menuitem&gt;
      &lt;menuitem label="Decrease Font" onclick="decFont()"&gt;&lt;/menuitem&gt;
    &lt;/menu&gt;
    &lt;li contextmenu="ChangeImage" id="changeImage"&gt;On the image below, you can fire the "Change Image" action in your Context Menu.&lt;/li&gt;&lt;br /&gt;
    &lt;img src="https://developer.mozilla.org/media/img/promote/promobutton_mdn5.png" contextmenu="ChangeImage" id="promoButton" /&gt;
    &lt;menu type="context" id="ChangeImage"&gt;
      &lt;menuitem label="Change Image" onclick="changeImage()"&gt;&lt;/menuitem&gt;
    &lt;/menu&gt;
  &lt;/ol&gt;
&lt;/body&gt;
</pre>

<p>...used with this JavaScript...</p>

<pre class="brush:js">
function incFont(){
  document.getElementById("fontSizing").style.fontSize="larger";
}
function decFont(){
  document.getElementById("fontSizing").style.fontSize="smaller";
}
function changeImage(){
  var j = Math.ceil((Math.random()*39)+1);
  document.images[0].src="https://developer.mozilla.org/media/img/promote/promobutton_mdn" + j + ".png";
}</pre>
