In starting markup, pages should now be identified with the attribute data-role="page". This allows us to then add ui-page programatically, hiding all non-active pages, and apply ui-page-active to one page at a time to show it. mobile.js is updated to find pages by this attribute now, instead of ui-page class. fixes issue 32

<p>Every element can have one to many queues of functions attached to it by jQuery. In most applications, only one queue (called <code>fx</code>) is used. Queues allow a sequence of actions to be called on an element asynchronously, without halting program execution. The typical example of this is calling multiple animation methods on an element. For example:</p>
|
|
<pre>$('#foo').slideUp().fadeIn();</pre>
|
|
<p>When this statement is executed, the element begins its sliding animation immediately, but the fading transition is placed on the <code>fx</code> queue to be called only once the sliding transition is complete.</p>
|
|
<p>The <code>.queue()</code> method allows us to directly manipulate this queue of functions. Calling <code>.queue()</code> with a callback is particularly useful; it allows us to place a new function at the end of the queue.</p>
|
|
<p>This feature is similar to providing a callback function with an animation method, but does not require the callback to be given at the time the animation is performed.</p>
|
|
<pre>$('#foo').slideUp();
|
|
$('#foo').queue(function() {
|
|
alert('Animation complete.');
|
|
$(this).dequeue();
|
|
});</pre>
|
|
<p>This is equivalent to:</p>
|
|
<pre>$('#foo').slideUp(function() {
|
|
alert('Animation complete.');
|
|
});</pre>
|
|
<p>Note that when adding a function with <code>.queue()</code>, we should ensure that <code>.dequeue()</code> is eventually called so that the next function in line executes.</p>
|
|
<p>In jQuery 1.4 the function that's called is passed in another function, as the first argument, that when called automatically dequeues the next item and keeps the queue moving. You would use it like so:</p>
|
|
<pre>$("#test").queue(function(next) {
|
|
// Do some stuff...
|
|
next();
|
|
});</pre>
|
|
</div>
