    <p>You can store a reference to a SVG object created in a simple javascript variable. So, when you create a shape, you can do this:</p> <pre><code>myRect = document.createElementNS("http://www.w3.org/2000/svg", "rect"); </code></pre> <p>Now you have the reference to a shape of the SVG object. But if you want to make them interactive, you just have to add attributes to the object like this.</p> <pre><code>myRect.setAttribute("onclick", "jsFunc()"); </code></pre> <p>where jsFunc() is a previously defined function. Also, to make things easier, you can set the events this way:</p> <pre><code>myRect.onclick = function(){jsFunct(this, otherArg);} </code></pre> <p>Now You can not only have the reference to the variable, but to pass the variable itself to the function jsFunc using such alternative through the use of the pointer this.</p> <p>If you have to create a lot of Rectangles, you can store them all in a single Array, so you are able to access each element using an index:</p> <pre><code>myRect = new Array(); for(i = 1; i &lt;= numMakes; i = i + 1){ myRect[i] = document.createElementNS("http://www.w3.org/2000/svg", "rect"); } </code></pre> <p>Remember, to get a property or attribute of your object, you can use the function getAttribute, like this:</p> <pre><code>fillColor = myRect.getAttribute("fill"); x = myRect.getAttribute("x"); </code></pre> <p>and so on.</p> <p>You could create a new variable type object, and establish that one member is the svg shape, and the rest of members are your customized data fields. </p> <pre><code>var myRect = new Object(); myRect.shape = document.createElementNS("http://www.w3.org/2000/svg", "rect"); myRect.customField = myValue; </code></pre>

    3. COOk, but how can I determine that parent-object using a shape? Do you propose to go through array of parent-objects and detect which of them contains my shape?

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.
