Body
It can be improved further, but something like this would work: <pre><code>$("#Table1 tr").each(function(i) { $(this).find("img").each(function(j) { this.id = "row" + i + "Seat" + j; $(this).hover(function() { this.src = "images/taken.gif"; }, function() { this.src = "images/available.gif"; }) .click(function() { var img = this; this.src = "images/mine.gif"; $(this).unbind("mouseenter mouseleave"); $("#myTickets").html(function(i, h) { return h + img.id; }); }); }); }); </code></pre> Using <a href="http://api.jquery.com/each/" rel="nofollow"><code>.each()</code></a> and the index it passes as the first parameter to the callback shortens it a bit (you don't need your own <code>i</code> and <code>j</code>, they're already there) the rest is just jQuery conversion, e.g. <a href="http://api.jquery.com/hover/" rel="nofollow"><code>.hover()</code></a> for the mouse entering/leaving and <a href="http://api.jquery.com/unbind/" rel="nofollow"><code>.unbind()</code></a> to remove those handlers it later. <hr> Here's a bit more verbose but much more efficient version using <a href="http://api.jquery.com/delegate/" rel="nofollow"><code>.delegate()</code></a>: <pre><code>$("#Table1 tr").each(function(i) { $(this).find("img").each(function(j) { this.id = "row" + i + "Seat" + j; }); }); $("#Table1").delegate("tr img", "click", function() { var img = $(this).addClass("mine").add("src", "images/mine.gif"); $("#myTickets").html(function(i, h) { return h + img.attr("id"); }); }).delegate("tr img:not(.mine)", "mouseenter", function() { this.src = "images/taken.gif"; }).delegate("tr img:not(.mine)", "mouseleave", function() { this.src = "images/available.gif"; }); </code></pre> This attaches only 3 handlers to the <code><table></code> and listens for events to bubble up, rather than attaching 3 handlers per image, so it's much cheaper on the page load side, and and infinitesimal difference on the runtime side.

Guidance

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.
