Body
I would first add a callback to <code>asyncMeth</code> that is called whenever the function has finished doing whatever it is doing. Otherwise there is no way to know if <code>asyncMeth</code> has finished its work. In your example what you have isn't the same as what you want! You want <code>ads[i]</code> to process 3 seconds after <code>ads[i - 1]</code> has finished. Instead, what you have is code to start processing <code>ads[i]</code> 3 seconds after <code>ads[i - 1]</code> has started processing. With a callback to <code>asyncMeth</code>, you can then do this: <pre><code>(function work(i) { if(i < ads.length) { asyncMeth(ads[i], function() { work(++i); }); } }(0); </code></pre> Here you have a self-invoked function that initially accepts a parameter value of <code>0</code>. This value is assigned to the parameter <code>i</code>. If <code>i</code> is lesser than <code>ads.length</code>, it means that we still have items to process. So it calls <code>asyncMeth</code> with <code>ads[i]</code> as a parameter. But then we also provide a callback. In this callback we tell the callback to call <code>work</code> with the incremented the value of <code>i</code>. This means that <code>work</code> will start processing the next item. So now you can asynchronously-process each item one after the other until <code>i</code> becomes equal to <code>ads.length</code>, at which point you have processed all the items. EDIT I noticed that you mentioned that you want a 3-second delay. For that you can do this: <pre><code>(function work(i) { if(i < ads.length) { asyncMeth(ads[i], function() { setTimeout(function() { work(++i); }, 3000); }); } }(0); </code></pre> The only difference here is that the next iteration happens 3 seconds after the last one has completed.

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.
