<p>The <code>.triggerHandler()</code> method behaves similarly to <code>.trigger()</code>, with the following exceptions:</p>
<ul>
<li>The <code>.triggerHandler()</code> method does not cause the default behavior of an event to occur (such as a form submission).</li>
    <li>While <code>.trigger()</code> will operate on all elements matched by the jQuery object, <code>.triggerHandler()</code> only affects the first matched element.</li>
    <li>Events created with <code>.triggerHandler()</code> do not bubble up the DOM hierarchy; if they are not handled by the target element directly, they do nothing.</li>
    <li>Instead of returning the jQuery object (to allow chaining), <code>.triggerHandler()</code> returns whatever value was returned by the last handler it caused to be executed. If no handlers are triggered, it returns <code>undefined</code>
</li>
    </ul>

Added viewport meta elements to the markup of every template and removed the metaViewportContent option from code and docs. IE does not support generated viewport tags. 2011-02-18 20:00:18 +00:00			`<meta charset="utf-8">`

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.
