    <p>I'm the author of enquire.js, so hopefully I'll be able to help you ;-)</p> <p>Basically, you want to add an event handler on match and remove event handler on unmatch. You seem to have the gist of how to do this above, but you've got the syntax a little wrong. Once the syntax is corrected it's just some jQuery knowledge to remove the click handler.</p> <p>So let's look at how the syntax should be:</p> <pre><code>enquire.register("screen and (max-width:500px)", { match: function() { //match code here }, unmatch: function() { //unmatch code here } }).listen(); </code></pre> <p>Notice that match and unmatch are part of a single object supplied to <code>register</code>.</p> <p>Ideally you should be putting this in your document ready callback. To assign your click handler use jQuery's <code>on</code> method, as this allows you to use the <code>off</code> method to unassign:</p> <pre><code>$(".block .block-title").on("click", function() { alert("hello"); }); $(".block .block-title").off("click"); </code></pre> <p>This is great because you can even namespace your events, read up on the jQuery docs for more details on this. So to put it all together, we would have this:</p> <pre><code>$(document).ready(function() { var $target = $(".block .block-title"); enquire.register("screen and (max-width:500px)", { match: function() { $target.on("click", function() { alert("Hello World!"); }); }, unmatch: function() { $target.off("click"); } }).listen(); });​ </code></pre> <p>You can find a working example here: <a href="http://jsfiddle.net/WickyNilliams/EHKQj/" rel="noreferrer">http://jsfiddle.net/WickyNilliams/EHKQj/</a></p> <p>That should then be all you need :) Hope that helps!</p>

    1. COHa, thanks Nick. I was hoping you would show up :P. This answer really helped and goes a long way for fixing up some of my other snippets. Thanks for the answer and thanks for creating enquire.js. Combined with modernizr it has helped me gain interest in creating smart javascript enhancements for my work.

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.
