Primer for Using jQuery Plug-Ins

From slideshows and sliders, to forms & mobile apps,   jQuery plug-ins are an easy way to add advanced web features (widgets) to your site without a lot of heavy manual coding.  Knowing how to use jQuery plug-ins will open up a whole new world of possibilities to you.
  1. Download the Plug-in files from the source site. I'm using jQuery Cycle in this example.
  2. For .zip file downloads, extract all contents with WinZip or StuffIt and save to your local site folder.  Click on screenshot.

    For plain text files, simply copy & paste the Plug-in code into a new blank JavaScript page and SaveAs: plug-in-name-ver.js to your local site folder.
  3. For site management reasons, I prefer to keep scripts in my Scripts folder, CSS files in my Styles folder and images in my Images folder but that's up to you. 
  4. jQuery has 3 basic parts to it:    
    1. the core code library which you ref in your <head> tags,
    2. the plug-in scripts & CSS files (if any) which you ref in your <head> tags,
    3. the function code inside <script> tags to invoke the plug-in. 

<!doctype html>
<meta charset="utf-8">
<title>jQuery Plug-In Page</title>

<!-- jQuery latest core library from CDN-->
<script type="text/javascript" src="">

<!-- links to plug-in files within your local site-->

<script type="text/javascript" src="Scripts/jquery.cycle.all.latest.js"></script>
<link rel="stylesheet" type="text/css" href="Styles/plug-in-name.css" media="screen" />


<div class="slideshow">
     <img src="Images/slide1.jpg" width="200" height="100" alt="description" />
     <img src="Images/slide2.jpg" width="200" height="100" alt="description" />
     <img src="Images/slide3.jpg" width="200" height="100" alt="description" />
     <img src="Images/slide4.jpg" width="200" height="100" alt="description" />

<!--Plug-In Function Code-->
<script type="text/javascript">
$(document).ready(function() {
     fx: 'fade'


  • Ensure paths to your plug-in files are correctly pointing to file & folder names within YOUR site folder.
  • Linux servers are cAsE sEnSiTiVe. For best results use all UPPER or all lower case file names.
  • Don't use spaces in file or folder names. Dots, dashes or underscores are fine but not spaces.
  • Lastly, refer to your particular Plug-in's official documentation for the correct function code, fx,  and classes to use.
That's all there is to it.  I hope you enjoyed this brief introduction to using jQuery Plug-Ins.

Create Pop-up Window in Dreamweaver (Behaviors Panel)

Creating a JavaScript Behavior

  1. Insert an image or type some text on your page.
  2. Highlight text or select image by clicking on it and go to the Link field in your Properties Panel as in (Fig. 1).
  3. Fig. 1
  4. Browse for the file or type the full URL:
  5. Go to the Behaviors Panel and hit the plus sign (+) to add a new behavior (see Fig. 3)
  6. From the menu, select Open Browser Window (Fig. 2)
  7. Browse to file or type the URL (Yes, a 2nd time).
  8. Set the height, width and other optional attributes for your pop-up window.
  9. Fig.2
  10. Hit OK.
  11. Verify that the behavior's trigger event is <A> onClick.  If it's not, click inside the event box to show other trigger options.
  12. Fig. 3
  13. Go back to the Properties Panel (Fig. 4) and replace the first URL in the link field with javascript:()  This makes the primary link into a null link so the page doesn't open twice.
  14. Fig. 4
  15. Save your page and preview in browsers.
That's all there is to it.  Hope you enjoyed this brief tutorial.

Working With Dreamweaver Templates (.dwt files)

PART 1 -- Template Creation

  1. Create a page with all the site wide elements (common header, footer, sidebar, etc..) that you will need for your project.   This requires some careful planning even for small web sites.
  2. Validate your code with the W3C code validation tools.
    CSS -
    HTML -
  3. Test your prototype page in all major browsers. 
  4. When you're completely satisfied with the page layout, SaveAs Template.   DW will save this as a .dwt file in a site folder called Templates.
  5. DW will ask you to add Editable Regions for stuff that will change from page to page.   Do this and hit SAVE (Ctrl+S).
  6. Close your Template.dwt file.

PART 2 -- Home Page Creation

  1. File > New Page > from Template.  Select the template you wish to use.  Hit OK.
  2. This is known as a child page.  You can only edit content within editable regions.  Everything else is locked or grayed out.
  3. SaveAs index.html (your domain home page) in the root of your local site folder.

PART 3  -- Creating Other Site Pages

  1. Repeat PART 2 for each additional page required.

PART 4  --  Editing Templates

  1. Open your main TEMPLATE.dwt file and add a navigation menu with links to your site pages.
  2. SAVE (Ctrl+S).
  3. DW will ask if you want to populate changes to child pages.  Hit yes.
  4. Publish all site pages to your server.


If you ever need to edit your TEMPLATE.dwt file, Repeat PART 4 and re-publish all child pages.

Adding a Blogger RSS Feed to an HTML Page

This brief tutorial shows how to add your Blogger RSS Feeds to your main web site.   NOTE: For this to work, your server must support .php and server-side includes.

Locate your Blogger's RSS Feed

Type the following URL into your browser's address bar:

Replace your_blog with your actual blogger site name.  Hit enter.

As an example, this blog's RSS feed is located at:

Parsing an XML feed into HTML

You need a script to parse XML into HTML otherwise it will appear as an un-styled mess.  FeedForAll RSS Creation Tool  has a free PHP script for displaying RSS feeds in HTML pages.  Download zip: RSS2HTML

Configuration of RSS2html

Unzip the folder.  Open the rss2html-docs.txt file in Dreamweaver or your favorite plain text editor and read the instructions.  Actually it's very simple to implement by modifying a few lines of code in the rss2html.php file:

Tell the script where to find your RSS Feed:

 $XMLfilename = "";

Tell the script where to find your RSS Template on your web site (not blogger):

$TEMPLATEfilename = "";

Tell the script how many feed items to display in your HTML page.

The default value is 1000.  I personally prefer 5 or possibly 10 items max.

$FeedMaxItems = 10000;

Tell your script how many characters to display from your blog post.

The default value of 0 includes everything.  150 is a nice number.

$limitItemDescriptionLength = 150;

The rest of the items are optional. Adjust them at will.  Save rss2html script with a .php extension and upload to your site.

Style your RSS template

Open the sample-template.html page.  Replace everything in code view with the following snippet of HTML code.

<p>~~~ItemPubShortDate~~~ ~~~ItemPubShortTime~~~</p>
<p><a href="~~~ItemLink~~~">~~~ItemTitle~~~</a></p>

Save sample-template.html and upload to your server.

Finally, open your main web site's home page (or whichever page you want the your blogger feed to appear on).  Scroll down to where you want it to display and insert a Server-Side Include pointing to the rss2html.php script.

<!--#include file="rss2html/rss2html.php" -->

For this to work, you'll need to save your index.html page with a .php or .shtml extension. This is necessary to parse includes on the server.   Delete old index.html page from server.

Go to your remote site and preview in browsers.   That's all there is to it.
We hope you enjoyed this tutorial.

Continuously Playing Music on Websites

People often ask this in forums and message boards.  "How to build an HTML site with music that plays continuously?"

Unfortunately, this isn't a simple thing. You have the following options, each with their own set of problems.

OPTION #1 - Embed an MP3 player on a plain vanilla page. Invoke it to open in a Pop-Up window from a link on your home page.   The player will remain open while people explore other site pages or until they close the pop-up window or leave your site.  NOTE:  The user must initiate the pop-up window. If you attempt to open a pop-up automatically on page load, it will be defeated by pop-up blockers (98% of browsers).

OPTION #2 - Put your player into a frameset.  NOTE: Framed sites pose many other problems as detailed below.

OPTION #3 - Build your entire site with Flash.  NOTE: Flash sites are not SEO & user friendly. Also Flash isn't supported by many web devices, most notably Apple's iDevices.

OPTION #4 - Build your entire site on one very large page
Depending on content and page size, this could delay your page load quite a bit.

OPTION #5 - Forget about continuous playing music/sound.  Simply embed your media player on the first page and allow people hear it once.
