    <p>Let's say you do a <code>$.post</code> to your server, with the selected company. Let's say the user selected company 1. Then, on the server, you want to a query like:</p> <pre><code>SELECT position.level, position.name FROM position JOIN company_position ON position.id = company_position.pid JOIN company ON company.id = company_position.cid WHERE company.id = ? </code></pre> <p>Now, you should have a result set with <code>(1, SE), (2, SE1), (3, SE2)</code> given your data above. I would send this back as a JSON object (I don't know what server environment you have, so building this structure is up to you):</p> <pre><code>{ "min": 1, "max": 3, "positions": { "1": "SE", "2": "SE1", "3": "SE2" } } </code></pre> <p>Alternately, if there are few positions, you could let the client calculate max and min, just sending JSON:</p> <pre><code>{ "1": "SE", "2": "SE1", "3": "SE2" } </code></pre> <p>And calculating max, min with javascript:</p> <pre><code>var max = Math.max.apply(null, Object.keys(response)) , min = Math.min.apply(null, Object.keys(response)); </code></pre> <p>In your javascript, given the object</p> <pre><code>var result = { "min": 1, "max": 3, "positions": { "1": "SE", "2": "SE1", "3": "SE2" } }; </code></pre> <p>You can query that object like this: <code>positions["1"] == "SE"</code>. So, if you want to show the labels for min and max, you would find the values for min and max like so:</p> <pre><code>var min = result.min, max = result.max </code></pre> <p>And you find their labels like this:</p> <pre><code>var minLabel = result.positions[result.min] , maxLabel = result.positions[result.max]; </code></pre>

    1. COonce I have the data, should I again loop (`$.each(data, function(key, val) {`) and put them in a 2D array? Or, is there a way to directly read a value by passing a key?

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.
