<p>This method is a shortcut for <code>.bind('error', handler)</code>.</p>
<p>The <code>error</code> event is sent to elements, such as images, that are referenced by a document and loaded by the browser. It is called if the element was not loaded correctly.</p>
<p>For example, consider a page with a simple image:</p>
<pre>&lt;img src="missing.png" alt="Book" id="book" /&gt;</pre>
<p>The event handler can be bound to the image:</p>
<pre>$('#book').error(function() {
  alert('Handler for .error() called.')
});
</pre>
<p>If the image cannot be loaded (for example, because it is not present at the supplied URL), the alert  is displayed:</p>
<p><span class="output">Handler for .error() called.</span></p>
<blockquote>
<p>This event may not be correctly fired when the page is served locally. Since <code>error</code> relies on normal HTTP status codes, it will generally not be triggered if the URL uses the <code>file:</code> protocol.</p>

added a jQuery api viewer demo. NOTE: content is a modified version of the downloadable HTML from http://jqapi.com 2010-09-16 17:13:38 +00:00			`<!DOCTYPE html>`

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.
