    <p>In jQuery mobile I am using an iframe. When you press the back button (in the app or the browsers back button) the iframe content goes away. Then when you press the back button again the app transitions to the previous page.</p> <p>The iFrame is getting added to history. I thought this was never supposed to happen.</p> <p>A <a href="http://jsfiddle.net/kolban/6achL3ez/" rel="nofollow">jsFiddle</a> has been created that illustrates the puzzle in as simple a form as possible.</p> <p>In it you will find a fragment of HTML that creates two jQuery Mobile pages. On the first page there is a link to go to the second page. On the second page,there are two back buttons (one on the header and one as a button on the page) and also a button to reload the <code>&lt;iframe&gt;</code>. To recreate the problem:</p> <ul> <li>From page 1 follow the link to page 2</li> <li>On page 2, click the button to load the <code>&lt;iframe&gt;</code></li> <li>Click either of the back buttons</li> </ul> <p>You will notice that you do <strong>not</strong> go back to page 1.</p> <p>Here is the HTML:</p> <pre><code>&lt;div data-role="page"&gt; &lt;p&gt;This is page 1&lt;/p&gt; &lt;a href="#page2"&gt;Go to page 2&lt;/a&gt; &lt;/div&gt; &lt;div data-role="page" id="page2"&gt; &lt;div data-role="header" data-add-back-btn="true"&gt; &lt;h1&gt;Page 2&lt;/h1&gt; &lt;/div&gt; &lt;p&gt;This is page 2&lt;/p&gt; &lt;p&gt;What follows is the iFrame&lt;/p&gt; &lt;iframe id="i1" width="500" src="http://www.ibm.com"&gt;&lt;/iframe&gt; &lt;p&gt;This button issues a programmatic back&lt;/p&gt; &lt;button id="backButton"&gt;Go Back&lt;/button&gt; &lt;p&gt;This button loads new content into the iframe&lt;/p&gt; &lt;button id="reloadButton"&gt;Reload iFrame&lt;/button&gt; &lt;/div&gt; </code></pre> <p>Here is the JavaScript</p> <pre><code>$(function () { $("#backButton").click(function () { jQuery.mobile.back(); }); $("#reloadButton").click(function() { $("#i1").attr("src", "http://www.microsoft.com?x=" + Math.random()); }); }); </code></pre> <p>(This is the code you will find in the jsFiddle).</p>

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.

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