I’m a moral in a secret box,
An earthworm, chewing through a sour meal,
A home, still within the daisy farm.
Oh, black ants, parasites, nematodes.
This trunk’s cold with its precious relics.
Jackpot’s dying for foxy diggers.
I’m an end, a joke, a passing fad.
I’ve left my mark to make a payment,
Jumped in the lake with my mom and dad.

Nifty JavaScript Design Tricks

Clickable divs

Standard design practice dictates that the site logo or banner located at the top of the page links to the home page of the site. There are several methods for including such functionality into a design, including this JavaScript trick that transforms an entire element (e.g., any div) into a link pointing to the site root:

<div id="banner" onclick="location.href='/';" style="cursor:pointer;">
   [ content goes here ]
</div>

Hide/Validate JavaScript Code

JavaScript Comments

Commenting your scripts is an excellent and highly recommended practice. Here are two methods of commenting within a block of JavaScript.

<script type="text/javascript">

// Use two forward slashes for single line comments

/* Use this method for
multi-line comments */

</script>

Link to an External JavaScript File

This is the preferred method of including JavaScript files. It is invisible to non-JavaScript browsers, and keeps the document from breaking during validation. Use if possible.

<script src="external.js" type="text/javascript"></script>

Hiding JavaScript

Hiding JavaScript code from non-compliant browsers is rather easy, just employ the following lines of code:

<script type="text/javascript">
<!--

JavaScript goes here
JavaScript goes here

//-->
</script>

Unfortunately, JavaScript code does not validate as XHTML. Fortunately, it is possible to present your code as invisible to the validators by enveloping it with the following lines of code:

<script type="text/javascript">
<![CDATA[

JavaScript goes here
JavaScript goes here

]]>
</script>

Combining these two methods produces a deadly weapon in the hellish JavaScript battle:

<script type="text/javascript">
<!--//--><![CDATA[//><!--

JavaScript goes here
JavaScript goes here

//--><!]]>
</script>

And, an alternate method has been suggested, but sustains inconsistent consensus:

<script type="text/javascript">
/* <![CDATA[ */

JavaScript goes here
JavaScript goes here

/* ]]> */
</script>

Here is the same commenting method used for CSS:

<style type="text/css">
/* <![CDATA[ */

CSS goes here
CSS goes here

/* ]]> */
</style>

A slightly modified version of the previous method:

<style type="text/css">
/* //<![CDATA[ */
<!--

CSS goes here
CSS goes here

//-->
/* //]]> */
</style>

Here is yet another way to comment out CSS content:

<style type="text/css">
<!--/*--><![CDATA[/*><!--*/

CSS goes here
CSS goes here

/*]]>*/-->
</style>

Finally, although popular, avoiding this method has been recommended:

<script type="text/javascript">
//<![CDATA[
<!--

JavaScript goes here
JavaScript goes here

//-->
//]]>
</script>

Non-JavaScript Browser Support

Use the <noscript> tag to provide support for antiquated browsers and serve 'em some alternate content. The <noscript> tag operates according to the presence/absence of JavaScript. Consider the following:

<noscript>
 <p>This will not be displayed if JavaScript is enabled.</p>
</noscript>

Here is a specific example that would provide a user with the option to continue browsing without JavaScript:

<noscript>
 <p>
  It appears your browser doesn't support JavaScript.
  Please visit <a href="http://domain.tld/noscript.html">the no-script page</a>
  to see a non-JavaScript version of this page.
 </p>
</noscript>

I love reading these things..

Good times.

Ahh, the joys of stealing from people…

Good times.

i fight a hellish battle everyday.
always something or someone demanding attention,
time, effort. i am most often glad to help, but looking ahead
i see only miles and miles of work, stress, and struggle.
every moment is a profound gift that passes before it is realized.
i am learning how to put the needs of others ahead of my own.
the constant talking may very well drive me insane.

What are these trackbacks?

Website makeover in progress (again). Actually, this website will probably exist in a perpetually evolving state until the end of time. It is simply too much fun to tweak, build, and learn. I now consider this website a project devoted to writing articles and practicing WordPress, web design, scripting, accessibility, and SEO. So feel free to look around, read some Nonsense, and get into some Business, but don’t be surprised if the universe folds or the sky turns red during your visit…
