    <p>I know very little about JavaScript but despite this I'm trying to cobble something together on my wordpress blog. It's not working, and I don't know how to resolve it, and hey, that's what StackOverflow is for, right?</p> <p>Firstly, the error message is:</p> <pre><code>Error: element.dispatchEvent is not a function Source File: http://.../wp-includes/js/prototype.js?ver=1.6 Line: 3936 </code></pre> <p>It happens on page load. My page load handler is registered thusly:</p> <pre><code>Event.observe(window, 'load', show_dates_as_local_time); </code></pre> <p>The error goes away if I disable some other plugins, and this (plus googling) led me to conclude that it was a conflict between prototype and jQuery (which is used by some of the other plugins).</p> <p>Secondly I'm following the wordpress recommended practice of using <a href="http://codex.wordpress.org/Function_Reference/wp_enqueue_script" rel="nofollow noreferrer"><code>wp_enqeue_script</code></a> to add a dependency from my JavaScript to the Prototype library, as follows:</p> <pre><code>add_action( 'wp_print_scripts', 'depo_theme_add_javascript' ); function depo_theme_add_javascript() { wp_enqueue_script('friendly_dates', 'javascript/friendly_dates.js', array('prototype')); } </code></pre> <p>Now I'm also aware that there are some potential conflicts between jQuery and Prototype which are resolved using the jQuery <code>noConflicts</code> method. I've tried calling that from various places but no good. I don't <em>think</em> this is the problem because a) the <code>noConflict</code> function relates solely to the <code>$</code> variable, which doesn't seem to be the problem here, and b) I would <em>expect</em> wordpress to sort it out for me because it can...</p> <p>Lastly, using the Venkman debugger I've determined that the <code>element</code> referenced in the error message is indeed an <code>HTMLDocument</code> but also does lack a <code>dispatchEvent</code>. Not sure how this could happen, given it's a standard DOM method?</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.
