    <p>And this is where you learn about scoping. You've defined <code>myFunction</code> inside the success handler, so it can only be called from inside the success handler. However, your <code>&lt;a href="..."&gt;</code> lives in <code>window</code> scope (because in the success handler it's just a meaningless text string, and the <code>append</code> call turns it into a a real HTML element that has access only to the <code>window</code> scope), which doesn't know about your <code>myFunction</code> function, so now you're trying to call a function that does not exist.</p> <p>In JavaScript, everything is scoped (i.e., "visible to things in") to the function they are in. Variables declared with <code>var ...</code> inside a function X don't exist outside that function X, and functions defined inside a function X don't exist outside that function X.</p> <p>In this case, you want to do this, instead (noting that <code>value</code> is already a string, using <code>var string = String(value)</code> makes no sense):</p> <pre><code>var newElement = $("&lt;a href='#'&gt;" + ... + "&lt;/a&gt;...: " + ... + "&lt;/br&gt;"); newElement.click(myFunction); $('#data_box').append(newElement); </code></pre> <p>Except you don't, because you're using an <code>&lt;a href="#"&gt;</code>, and I'm 100% sure not trying to set up a link to the top of your page: <em>don't use <code>&lt;a&gt;</code> when you don't mean it</em>.</p> <p>What you <strong>really</strong> want, is this:</p> <pre><code>var newElement = $("&lt;div&gt;&lt;span&gt;" + ... + "&lt;/span&gt;...: " + ... + "&lt;/div&gt;"); newElement.find("span").click(myFunction); $('#data_box').append(newElement); </code></pre> <p>And yes, that doesn't have the <code>&lt;br&gt;</code> anymore either. Don't use break codes, use CSS.</p>

    2. COan `<a>` must have an href. If you just want click behaviour, you don't use the semantic link element. You use a span or a div or anything that doesn't have a semantic role assigned to it, and is styled as an inline-block (which a span is by default).

    3. COI do agree with that but semantically anchor is used for navigating from one place to other and if we slightly change this definition then it is fit for giving a feel of click so that an action can be made on it. Still no reason to remove it. Is this an rule that <a> must have an href, i dont think so ?

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.
