    <p>I am simply trying to display a google map within a jquery mobile page. If I load the page directly it works. However, if I navigate to the page from another page it only renders a single map tile. At first glance it would appear that my issue was similar to <a href="https://forum.jquery.com/topic/google-maps-inside-jquery-mobile">https://forum.jquery.com/topic/google-maps-inside-jquery-mobile</a></p> <p>However, I was already performing my initialization within the 'pageinit' event and my map div has a set width and height.</p> <p>I have seen <a href="http://code.google.com/p/jquery-ui-map/">http://code.google.com/p/jquery-ui-map/</a> but I would rather not use a (another) third party plugin if at all possible.</p> <p>Here's what my page looks like:</p> <pre><code>&lt;!DOCTYPE HTML&gt; &lt;html&gt; &lt;head&gt; &lt;title&gt;PhoneGap&lt;/title&gt; &lt;meta name="viewport" content="width=device-width, initial-scale=1"&gt; &lt;script src="cordova-1.6.1.js"&gt;&lt;/script&gt; &lt;link rel="stylesheet" href="jquery.mobile-1.1.0.min.css" /&gt; &lt;script src="jquery-1.7.1.min.js"&gt;&lt;/script&gt; &lt;script src="global.js"&gt;&lt;/script&gt; &lt;script src="jquery.mobile-1.1.0.min.js"&gt;&lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;div id="mapPage" data-role="page"&gt; &lt;style type="text/css"&gt; html { height: 100%; } body { height: 100%; margin: 0; padding: 0; } #map_canvas { height: 100%; } &lt;/style&gt; &lt;script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?key=***API_KEY_REMOVED***&amp;sensor=true"&gt; &lt;/script&gt; &lt;script type="text/javascript"&gt; function initialize() { var height = $(window).height() - 50; var width = $(window).width(); $("#map_canvas").height(height); $("#map_canvas").width(width); var myLatlng = new google.maps.LatLng(39.962799, -82.999802); var myOptions = { center: myLatlng, zoom: 18, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); //alert($(map.getDiv()).width()); var marker = new google.maps.Marker({ position: myLatlng, map: map, title: "" }); google.maps.event.trigger(map, 'resize') } $("#mapPage").live('pageinit', function () { initialize(); }); &lt;/script&gt; &lt;div data-role="header" id="menuHeader"&gt; &lt;a href="MenuDialog.htm" class="menuLink" data-role="none" data-rel="dialog"&gt; &lt;img class="headerIcon" style="height: 40px; border-right: 1px solid #333333; padding-right: 5px;" id="MenuIcon" src="images/menuIcon.png" /&gt;&lt;/a&gt; &lt;p&gt; Loc &lt;/p&gt; &lt;/div&gt; &lt;div data-role="content"&gt; &lt;div id="map_canvas" style="margin-top: 50px;"&gt; &lt;/div&gt; &lt;/div&gt; &lt;/body&gt; &lt;html&gt; </code></pre> <p>Thanks in advance for you help.</p> <p><strong>Update:</strong></p> <p>After some experimenting I added the following delay to my resize event:</p> <pre><code>setTimeout(function() { google.maps.event.trigger(map,'resize'); }, 500); </code></pre> <p>This seemed to fix the issue. Hopefully this helps someone else.</p>

    2. COThis works fantastically. While I feel it's quite hackey, there aren't a lot of options here. The timeout works great as it allows the map to render first before calling this to ensure a proper sizing. My only issue here is how can we be sure 500 ms is enough? A callback approach may work better, such as listening for the map to fire it's "idle" event. Idle didn't work for me though and I couldn't find another appropriate event to hook into. :(

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
