    <p>You're re-updating your HTML, thus a new DOM essentially each time you login/logout with your single screen application. jQuery will only find the <em>first loaded</em> instance of the DOM with your current selectors. Adjust them to look for the newly appended (Container) DOM Element <em>each</em> time.</p> <h2>Applying <code>.datepicker()</code> to an dynamically assigned <code>&lt;div&gt;</code></h2> <pre><code>var $datePickerEl = $(document).find('#fecha', $contenedor ); $(document).on('click', "#fecha", function(){ if( $datePickerEl.val() == ''){ $datePickerEl.datepicker('setDate', (new Date())); } }); </code></pre> <h2>Reassigning <code>.datepicker()</code> to same dynamically created DOM Element</h2> <p>Following your example you provided in your <a href="http://jsfiddle.net/L6s8U/2" rel="nofollow">fiddle</a>, which reloaded the contents of the DOM with a page of information, posed a problem that it was not re-starting the <code>.datepicker()</code> initialisation as expected. </p> <p>It because the new <code>.html()</code> reload was wiping out all the <code>.datepicker()</code> helper CSS &amp; <code>&lt;div&gt;</code>s, but <em>was</em> assigning the element with a new ID. By simply appending the content to a container, rather than the entire document <strong>and</strong> removing any instance of the ID and class that remained in the previous instance of the <code>datepicker()</code> the example code below successfully creates a new <code>.datepicker()</code> on demand.</p> <pre><code>&lt;div id="content"&gt;&lt;/div&gt; &lt;script&gt; function loadLogin() { $('#content').html('&lt;div id="pp"&gt;'+ '&lt;button id="login"&gt;Free login&lt;/button&gt;'+ '&lt;/div&gt;').trigger("create"); loadEvents(); } function loadEvents() { $div = $('&lt;h1&gt;Hi!!&lt;/h1&gt;' + '&lt;input type="text" class="datepick" /&gt;' + '&lt;button id="logout" style="margin-top: 100px;"&gt;Good bye!&lt;/button&gt;'); $("#pp").html($div).trigger("create"); /** * Find the newly appended .datepick * &amp;&amp; begin the .datepicker init. **/ $datepicker = $(document).find('.datepick'); $datepicker.datepicker(); $('#logout').click(function () { //Remove the attached id &amp;&amp; class. $datepicker.removeAttr('id').removeClass('hasDatepicker'); loadLogin(); }); } &lt;/script&gt; </code></pre> <p><strong>Demo Fiddle</strong>: <a href="http://jsfiddle.net/zP9L6/1/" rel="nofollow">http://jsfiddle.net/zP9L6/1/</a></p>

    1. COThanks for your answer, MackieeE. I tried your solutions and It still without working. I think like you, the problem is because there is some element on before DOM or some kind of conflict, but I can't find it. I tried with `$('#date', $div).datepicker({showOn:"button"});`. With this code everything works properly but the problem is the calendar is not showed, even using show(), because this container doesn't exist `<div id="ui-datepicker-div" class="ui-datepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all">`. I tried to destroy datepicker and doesn't work.

    2. COIf you think it might be a CSS issue, might need to post HTML/css - also, save the `datepicker` as a variable: http://jsfiddle.net/ba8Nj/2/

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).
