Use
JavaScript to Dynamically Update Your Website
By Shelley Lowery
If you've been on the Internet for a while, you've probably seen numerous
examples of JavaScript use. JavaScript is a powerful scripting language used to
create special effects on your website, but did you know it can also be used as
a very powerful web design tool?
Have you ever joined a new affiliate program or created a new publication that
you wanted to add to your existing navigational set up, but dreaded having to
manually add the links to every page on your site?
You can use JavaScript to enable you to dynamically update every page on your
website with just one file. This technique is the same technology used by
numerous syndication services on the Internet. It enables them to deliver
dynamically updated content to every website in their program.
Before we begin, if you'd like to see an example of a navigational system that
is dynamically displayed, visit
http://www.web-source.net.
This website has over one thousand pages and each and every one of them displays
its navigational system using JavaScript. If I want to add an additional link, I
simply update one file and every page on the site is automatically updated.
The first step in setting up your JavaScript feed is to create the file that
will contain your content. To do this, open a text editor such as NotePad and
simply copy and paste your existing navigational setup into a new page. There is
no need to begin the page with <HTML><HEAD>, etc. as you are only creating the
feed for one section of your existing web page which already has those tags.
Once you've created your new page containing your navigational HTML, you'll now
need to add some additional JavaScript coding to each line of your HTML.
The first line of your new file will look like this: <!--
The next line will begin with: document.writeIn(' and end with: ');
Your first line of HTML will be placed between the beginning and ending coding.
For every line of your original coding, you'll need to add the above-mentioned
codes before and after.
Note: Make sure you don't add any extra spaces, including at the end of each
line, as JavaScript is very sensitive.
Your new file will end with //--> on the last line.
Here's how your code might look:
<!--
document.writeln('<TABLE BORDER="0" ALIGN="Center">');
document.writeln('<TR>');
document.writeln('<TD>');
document.writeln('Your table content');
document.writeln('</TD>');
document.writeln('</TR>');
document.writeln('</TABLE>');
//--> |
Each backslash (\) should be preceded
with another backslash.
Example: \\
Each apostrophe (') should be preceded with a backslash.
Example: \'
You can include most HTML and JavaScript coding however, you cannot include
JavaScript that must access another file to run.
After you've created your content and added the special JavaScript coding,
you'll need to save your new file. Try to select a name that reflects your file
such as navigate.js and make sure your filename is no longer than eight letters.
Next, you'll need to create a new directory on your server where you store your
HTML files. Name this directory "content" (without the quotes) and upload your
new .js file in ASCII.
Here's where the magic occurs... Place the following code in your HTML pages
where you would like your navigate.js content to be displayed. Make sure you
change the URL and direct it to your new .js file. The following code must be
displayed exactly as it appears. Make sure there are no spaces after the first
line of code.
<SCRIPT
language="JavaScript" src="http://www.yourdomain.com/content/yourfile.js">
</SCRIPT> |
If you've followed the above steps
correctly, your navigational system should now be displaying on your web page.
If you are receiving a script error message, most of the time, it's due to an
extra space at the end of a line or an extra or missing character. Make sure you
go over your code very carefully. Once you've created your content feed and it
is displaying your content, updating your file will be simple.
If you'd rather not have to code the JavaScript yourself, I use a great script
called, Master Syndicator which will code your content for you. I highly
recommend it.

Using JavaScript to display your navigational set up can not only enable you to
instantly update the content on every page of your website, but can also save
you hours of valuable time.
