    <p>I'm doing a javascript assignment and have just learned that I can do it in jQuery if I wish, rather than vanilla javascript. I thought I'd give it a go to see what it's like.</p> <p>This is the contents of my javascript function:</p> <pre><code> rowsArray = $("#Table1 tr"); for (i=0;i&lt;rowsArray.length;i++){ numSeatsInRow = rowsArray[i].getElementsByTagName("img").length; // discovers the number of seats in row [i] for(j=0;j&lt;numSeatsInRow;j++) { // loops round once for each set in row [i] var currentSeat = rowsArray[i].getElementsByTagName("img")[j]; currentSeat.setAttribute("id","row" + i + "Seat" + j); currentSeat.onmouseover = function(){this.src = "images/taken.gif"}; currentSeat.onmouseout = function(){this.src = "images/available.gif"}; currentSeat.onclick = function() { this.src = "images/mine.gif"; this.onmouseover = null; this.onmouseout = null; document.getElementById("myTickets").innerHTML += this.id; } } </code></pre> <p>As you can see, I started converting to jQuery with the first line, but got stuck :)</p> <p>The code works as is, but I figure there must be a more elegant way of doing it in jQuery. I tried using $.each but my selectors or syntax was wrong and it didn't work. I have a vague idea how it works for a 1D array, but I'm not clear on how to iterate through the items in nested arrays i.e. array[x][y].</p> <p>The function creates and moves through a 2D array changing the id and mouse events of a set of images.</p> <p>Any thoughts would be much appreciated :)</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.
