    <p>EDIT: Seems i didnt use an 'id' on my textarea, so that problem has cleared up but i'm still getting a few problems with text()</p> <pre><code>var e = $('textarea#cost-'+i).val(); // e = 1 (for first iteration) alert($('p#subtotal-'+i).text()); // alert 'subtotal' which is the text in my p#subtotal-1 $('p#subtotal-'+i).text().replaceWith(e); // &lt;- this is the problem, i think alert($('p#subtotal-'+i).text()); // no alert box at all </code></pre> <p>and this time i made sure they all have ids.</p> <hr> <p>The following code, generates an alert box with nothing in it. If i change it to val() it says 'undefined'</p> <hr> <pre><code>$('textarea.costbox').live('blur',function() { for(var i in items) { alert('iteration '+i); alert('textarea#cost-'+i); var e = $('textarea#cost-'+i).text(); alert('cost '+e); } }); </code></pre> <hr> <pre><code>&lt;textarea name="cost-1" class="costbox"&gt;&lt;/textarea&gt; </code></pre> <hr> <p>The idea for this code is to update a subtotal when the value has been changed. This is the last piece of the puzzle.</p> <p>All the HTML looks normal when i inspect it in chrome. And all the rest of my code is working fine.</p> <p>This should be running with modernizer1.7 and jQuery1.5.1, based off recent HTML5Boilerplate.</p> <p>Here's another example of the same basic thing - <a href="http://jsbin.com/obeho5/3/edit" rel="nofollow">http://jsbin.com/obeho5/3/edit</a></p> <p>Its probably something simple but i've been stuck here for hours and can't see it.</p> <p>[if its not something obvious and simple i can post more code]</p>

    2. COwhat is items supposed to be and where do you get it from? Have you printed out (either firebug's console.log or alerts) what "i" is?

    3. CO'items' was going to be an array to help calculate the subtotal, but i found a better way. and 'i' wasnt the problem, the loop was working properly.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
