    <p>I have a function that calls jQuery's pulse function. I use it on a small graphic in the client interface that indicates that some data is in the process of being synchronized with the server. While the data is being transferred, the pulse function takes effect, making the graphic look like a flickering light.</p> <p>Alongside that little indicator graphic, is some text. So, when the synchronization is complete, the pulse is stopped, the graphic turns green, and the text says "data synced".</p> <p>All well and good, except that for reasons I don't understand, the function to stop the pulse effect works only about 50% of the time. However, the text that gets changed to say "data synced" works 100% of the time.</p> <p>How is it that I can get to the point in the code where both actions are executed, and yet only one actually happens? It seems to me they should either both work or both fail. (I have tried changing their order, but that does not have any effect on the problem.)</p> <p>Here is the code in question. The first function executes when data begins synchronizing, the other executes when the server sends back a JSON saying "all good: data synchronized".</p> <p>Also note, I'm kind of a noob, so please dumb down answers to my level.</p> <pre><code>function syncDataStart() { $(document.getElementById("indicator")).pulse( { backgroundColor: ["yellow", "orange"] }, 100, 9999, "linear"); document.getElementById("indicator-text").innerHTML = "synchronizing data"; } function syncDataComplete() { document.getElementById("indicator-text").innerHTML = "data synced"; $(document.getElementById("indicator")).stop(); document.getElementById("indicator").style.backgroundColor = "green"; } </code></pre>

    1. COWhy $(document.getElementById("indicator"))? Why not $("#indicator")?

    2. COYou have not included the relevant portions of the code - the important part here is the code that's actually calling these two functions, not the functions themselves

    3. COUsing the # character breaks the code completely. Also, I don't see why the code that calls the two functions is relevant. The important point is that the functions are called, and what happens in the function should be executed. If you can explain to me how the code that calls the function would only cause it to be half-executed, then I would see the relevance.

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.
