    <p>I have an issue with the jQuery Mobile 1.3.1 table widget which I think is related to widget lifetime.</p> <p>I'm using the table widget in columntoggle mode in a page. On first use of the page there are no issues. If I then navigate around my site (without refreshing the browser window) and then go back to the page there seem to be two instances of the widget hanging around. The older one raises an error if I try and resize the page, I think because it's attempting to manipulate elements that were unloaded.</p> <p>Example code is below and published in this fiddle: <a href="http://jsfiddle.net/cjindustries/thqga/" rel="nofollow">http://jsfiddle.net/cjindustries/thqga/</a> (Navigate to page 2, then resize the browser. The removal of the elements emulates JQM unloading the page.).</p> <p>Can anyone explain to me how jQuery Mobile manages widgets in general and if/how I need to actively destroy widgets in this scenario?</p> <p>Thanks, Chris.</p> <pre><code>&lt;div id="p1" data-role="page"&gt; &lt;table data-role="table" id="table1" data-mode="columntoggle" class="ui-responsive table-stroke"&gt; &lt;thead&gt; &lt;tr&gt; &lt;th data-priority="2"&gt;Rank&lt;/th&gt; &lt;th&gt;Movie Title&lt;/th&gt; &lt;th data-priority="3"&gt;Year&lt;/th&gt; &lt;th data-priority="1"&gt;&lt;abbr title="Rotten Tomato Rating"&gt;Rating&lt;/abbr&gt;&lt;/th&gt; &lt;th data-priority="5"&gt;Reviews&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;tr&gt; &lt;th&gt;1&lt;/th&gt; &lt;td&gt;&lt;a href="http://en.wikipedia.org/wiki/Citizen_Kane" data-rel="external"&gt;Citizen Kane&lt;/a&gt;&lt;/td&gt; &lt;td&gt;1941&lt;/td&gt; &lt;td&gt;100%&lt;/td&gt; &lt;td&gt;74&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;a href="#p2" data-role="button"&gt;Page 2&lt;/a&gt; &lt;/div&gt; &lt;div id="p2" data-role="page"&gt; &lt;table data-role="table" id="table2" data-mode="columntoggle" class="ui-responsive table-stroke"&gt; &lt;thead&gt; &lt;tr&gt; &lt;th data-priority="2"&gt;Rank&lt;/th&gt; &lt;th&gt;Movie Title&lt;/th&gt; &lt;th data-priority="3"&gt;Year&lt;/th&gt; &lt;th data-priority="1"&gt;&lt;abbr title="Rotten Tomato Rating"&gt;Rating&lt;/abbr&gt;&lt;/th&gt; &lt;th data-priority="5"&gt;Reviews&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;tr&gt; &lt;th&gt;7&lt;/th&gt; &lt;td&gt;&lt;a href="http://en.wikipedia.org/wiki/The_Graduate" data-rel="external"&gt;The Graduate&lt;/a&gt;&lt;/td&gt; &lt;td&gt;1967&lt;/td&gt; &lt;td&gt;91%&lt;/td&gt; &lt;td&gt;122&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;a href="#p1" data-role="button"&gt;Page 1&lt;/a&gt; &lt;/div&gt; $(document).on('pageshow', '#p2', function () { $('#p1').html(''); }); </code></pre>

    1. COCan you show use your page code, specially your js code. This problem is related to event binding. And you are correct it is a common problem but it can happen in so many different ways that we need your code to determine your exact problem.

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).
