<div class="longdesc">
<p>This method is a shortcut for <code>.bind('dblclick', handler)</code> in the first two variations, and <code>.trigger('dblclick')</code> in the third.
The <code>dblclick</code> event is sent to an element when the element is double-clicked. Any HTML element can receive this event.
For example, consider the HTML:</p>
<pre><div id="target">
Double-click here
</div>
<div id="other">
Trigger the handler
</div></pre>
<p class="image"><img src="/images/0042_05_04.png" alt=""></p>
<p>The event handler can be bound to any <code><div></code>:</p>
<pre>$('#target').dblclick(function() {
alert('Handler for .dblclick() called.');
});</pre>
<p>Now double-clicking on this element displays the alert:</p>
<p><span class="output">Handler for .dblclick() called.</span></p>
<p>To trigger the event manually, apply <code>.dblclick()</code> without an argument:</p>
<pre>$('#other').click(function() {
$('#target').dblclick();
});</pre>
<p>After this code executes, (single) clicks on <span class="output">Trigger the handler</span> will also alert the message.</p>
<p>The <code>dblclick</code> event is only triggered after this exact series of events:</p>
<ul>
<li>The mouse button is depressed while the pointer is inside the element.</li>
<li>The mouse button is released while the pointer is inside the element.</li>
<li>The mouse button is depressed again while the pointer is inside the element, within a time window that is system-dependent.</li>
<li>The mouse button is released while the pointer is inside the element.</li>
</ul>
<p>It is inadvisable to bind handlers to both the <code>click</code> and <code>dblclick</code> events for the same element. The sequence of events triggered varies from browser to browser, with some receiving two <code>click</code> events before the <code>dblclick</code> and others only one. Double-click sensitivity (maximum time between clicks that is detected as a double click) can vary by operating system and browser, and is often user-configurable.
