    <p>I'm trying to create H2 headings using prototype so they can be set individually as required. </p> <p>I'm using <code>this.appendChild(document.createTextNode(''));</code> to add text to the <code>H2</code>. I need to use the parent node before <code>appendChild</code> which I believe in this case is the <code>this</code> keyword but I'm not sure it's being recognised as the parent or if it actually is the parent ? I'm also uncertain as of how to add the text through a parameter of the constructor itself . I've used a variable 'font' but not sure how to make it work as its not adding a css style ?</p> <p>I'm learning how to use prototype so if there's any other obvious errors I've missed please let me know.</p> <pre><code>&lt;div id='body'&gt; &lt;div id='inner'&gt;div here&lt;/div&gt; &lt;/div&gt; &lt;script&gt; Heading.prototype.font; Heading.prototype.color; Heading.prototype.fontSize; Heading.prototype.headingTxt; Heading.prototype.setHeading = function() { var inner = document.getElementById('inner'); this.headingTxt = document.createElement('h2'); this.headingTxt.font = this.appendChild(document.createTextNode('')); this.headingTxt.style.color = this.color; this.headingTxt.style.fontSize = this.fontSize; inner.appendChild(headingTxt); } function Heading(font, color, fontSize) { this.font = font; this.color = color; this.fontSize = fontSize; } var title = new Heading('heading here', 'red', 20); title.setHeading(); &lt;/script&gt; </code></pre> <p>Can anyone help me how can resolve this issue ?</p>

    1. COWhich parent node? `this` refers to an instance of `Heading`, i.e. `title`, not to a DOM element.

    2. COAh clearly using `this` is wrong. I want it to refer to the `H2` element being created as the parent so the text node will be the child.

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.
