    <p>I've been noticing some odd behavior when trying to implement a configuration javascript file to enable/disable user interface features based on development or production environment, and can use some clarification.</p> <p>This is a flat application, and I've split the javascript into three files: index.js, dashboard.js and taxonomy.js. </p> <pre><code>&lt;script type = "text/javascript" src = "/static/js/taxonomy.js"&gt;&lt;/script&gt; &lt;script type = "text/javascript" src = "/static/js/dashboard.js"&gt;&lt;/script&gt; &lt;script type = "text/javascript" src = "/static/js/index.js"&gt;&lt;/script&gt; &lt;script type = "text/javascript" src = "/static/js/config.js"&gt;&lt;/script&gt; </code></pre> <p>The index script handles the login, logout and element initialization functionality. Its defined as </p> <pre><code>$(document).ready(function(){ $.ajax({ //query db for login success : function(){ loginHandler() } }); function loginHandler(){ initializeDashboardElements() initializeTaxonomyElements() } </code></pre> <p>Inside taxonomy.js, there is no <code>$(document).ready()</code> definition, but <code>initializeTaxonomyElements()</code> exists, which applies jQuery UI bindings to the specified HTML elements. One such element is a tab widget that currently contains 4 tabs, but is expected to grow. </p> <p>Inside <code>config.js</code>, I have this for the production environment:</p> <pre><code>$(document).ready(function(){ $("#tabs").tabs("option", "disabled", [1, 2]); }); </code></pre> <p>Given this setup, I get an error</p> <pre><code>Error: cannot call methods on tabs prior to initialization; attempted to call method 'option' </code></pre> <p>I've also tried this with <code>initializeTaxonomyElements()</code> within a <code>$(document).ready()</code> declaration. The same error occurs.</p> <p>Any suggestions to resolve this issue?</p>

    1. COWhere did you initialize the tabs widget? you can't call .tabs("option"...) before the tabs widget is initialized. you simply can't.

    3. COHow is it initialized within that function? after an ajax request? after an animation? after a setTimeout? after some other asynchronous method?

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.
