    <p>I need help, I want to create a function which returns an object from an AJAX request, so I can create a new object from data on the server like this:</p> <pre><code>var foo = bar('api.php?x=y'); </code></pre> <p>The function should take a query string as an argument, and the server returns data as JSON.</p> <p>Can you show me how to do this using jQuery, do you have any ideas/examples?</p> <p><em>I will expand on my question because it seems I am doing it all wrong.</em> I am trying to create a web application based on <strong>live data</strong> (stock quotes) so it has to constantly request updated information from the server. When the app is initialized the first step is getting static data from the stocks to be included (such as ticker symbol and issuer), I am thinking the best way to do this is to have a database on the server and an API which does the query and returns the selected stock data as JSON. The next step is to make a request to another API on the server which returns live data (such as price and volume) on the selected stocks, when the complete data is returned it is rendered to html using a template engine. Then the app has to constantly call the second API on some interval to update the live data and render again. Also you should be able to make a new selection of stocks and start the process again.</p> <p>I think the best way to structure an app like this is to have the data inside a custom object which has its own methods to modify the data later (for example sorting and filtering), so if <code>foo</code> is my object with the stock data I can do something like <code>foo.sort()</code>, or something like <code>foo.render()</code> to create the html representation of the data. That is why I thought the best way was to create an object from the data returned by the AJAX call. <em>Could you please tell me if this is the right way to structure an app like this or point me in the right direction?</em></p> <p>Thanks</p>

    1. COThere is an example on this page of the jQuery doco: http://api.jquery.com/jQuery.getJSON/ - see the other jQuery Ajax functions for more info. Note that your idea of calling a function to get the data won't quite work with an asynchronous Ajax call, but you can work around it.

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.
