<p>The <code>$.inArray()</code> method is similar to JavaScript's native <code>.indexOf()</code> method in that it returns -1 when it doesn't find a match. If the first element within the array matches <code>value</code>, <code>$.inArray()</code> returns 0.</p>
<p>Because JavaScript treats 0 as loosely equal to false (i.e. 0 == false, but 0 !== false), if we're checking for the presence of <code>value</code> within <code>array</code>, we need to check if it's not equal to (or greater than) -1.</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.
