    <p>Pardon me for giving you a confusing title on this problem. I'm really confused and i don't know how to put it in other words.</p> <p>So here is what I what to accomplish.</p> <p>I am making a Custom Javascript Object to store data. </p> <p>I have automated this process and inserted each instance of the object into an array.</p> <p>I am making a loop statement to invoke the unique property value of each instance of the object.</p> <p>When I want to use an expression, the property name of the object would be variable since i don't know which one it is.</p> <p>Basically I need to incorporate a string value into the prototype expression.</p> <p>e.g</p> <pre><code>document.getElementById('text').style."fontsize"=value; </code></pre> <p>since I cannot do this directly, i thought possibly I could use the eval function:</p> <pre><code>eval('document.getElementById("text").style.' + buttons[i].cssvalue + '="39px";'); </code></pre> <p>but this still doesn't work.</p> <p>Can this be fixed or ss there an alternative way to accomplish this?</p> <p>If there are some unclear stuff, please point out and I will try to elaborate.</p> <p>Thanks in advance.</p>

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.
