<p>This method is a shortcut for <code>.bind('mouseenter', handler)</code> in the first variation, and <code>.trigger('mouseenter')</code> in the second.</p>
<p>The <code>mouseenter</code> JavaScript event is proprietary to Internet Explorer. Because of the event's general utility, jQuery simulates this event so that it can be used regardless of browser. This event sent to an element when the mouse pointer enters the element. Any HTML element can receive this event.</p>
<p>For example, consider the HTML:</p>
<pre>&lt;div id="outer"&gt;
  Outer
  &lt;div id="inner"&gt;
    Inner
  &lt;/div&gt;
&lt;/div&gt;
&lt;div id="other"&gt;
  Trigger the handler
&lt;/div&gt;
&lt;div id="log"&gt;&lt;/div&gt;</pre>
<p class="image"><img src="http://api.jquery.com/images/0042_05_08.png" alt=""></p>
<p>The event handler can be bound to any element:</p>
<pre>$('#outer').mouseenter(function() {
  $('#log').append('&lt;div&gt;Handler for .mouseenter() called.&lt;/div&gt;');
});</pre>
<p>Now when the mouse pointer moves over the <span class="output">Outer</span> <code>&lt;div&gt;</code>, the message is appended to <code>&lt;div id="log"&gt;</code>. We can also trigger the event when another element is clicked:</p>
<pre>$('#other').click(function() {
  $('#outer').mouseenter();
});</pre>
<p>After this code executes, clicks on <span class="output">Trigger the handler</span> will also append the message.</p>
<p>The <code>mouseenter</code> event differs from <code>mouseover</code> in the way it handles event bubbling. If <code>mouseover</code> were used in this example, then when the mouse pointer moved over the <span class="output">Inner</span> element, the handler would be triggered. This is usually undesirable behavior. The <code>mouseenter</code> event, on the other hand, only triggers its handler when the mouse enters the element it is bound to, not a descendant. So in this example, the handler is triggered when the mouse enters the <span class="output">Outer</span> element, but not the <span class="output">Inner</span> element.</p>

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.
