<p>Given a jQuery object that represents a set of DOM elements, the <code>.prevAll()</code> method allows us to search through the predecessors of these elements in the DOM tree and construct a new jQuery object from the matching elements.</p>
<p>The method optionally accepts a selector expression of the same type that we can pass to the <code>$()</code> function. If the selector is supplied, the elements will be filtered by testing whether they match it.</p>
<p>Consider a page with a simple list on it:</p>
<pre>
&lt;ul&gt;
   &lt;li&gt;list item 1&lt;/li&gt;
   &lt;li&gt;list item 2&lt;/li&gt;
   &lt;li class="third-item"&gt;list item 3&lt;/li&gt;
   &lt;li&gt;list item 4&lt;/li&gt;
   &lt;li&gt;list item 5&lt;/li&gt;
&lt;/ul&gt;
</pre>
<p>If we begin at the third item, we can find the elements which come before it:</p>
<pre>$('li.third-item').prevAll().css('background-color', 'red');</pre>
<p>The result of this call is a red background behind items 1 and 2. Since we do not supply a selector expression, these preceding elements are unequivocally included as part of the object. If we had supplied one, the elements would be tested for a match before they were included.</p>

Big update: 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 2010-09-18 16:20:35 +00:00			`<div data-role="page">`
updated markup to use data-role attrs in place of classes for header/content/footer 2010-09-21 14:58:54 +00:00			`<div data-role="header">`

switched up padding and margins on content div. Now it will get 15px padding, unless its a fullscreen page. Inset listviews have no margin now, and regular listviews have -15px margins. Also, collapsibles now have no padding. Updated HTML to remove ui-body classes for content divs, to match these changes.
