Future Web Technology


I have talked about what the world would be like if there was no JavaScript
in use and in doing so, described it as the active partner to the passive HTML,
when it comes to basic Web page design.  If these two are the fundament for
the Web page, what else is there, and what does the future hold?


Consider for a moment technologies like ASP, PHP, MySQL and the like. 
These technologies are Server Side technologies, meaning that when they are
called upon to perform their duties, the software involved runs on the Web
Server computer systems, as opposed to HTML and JavaScript, which run on the
client side (where the Web Browser is running.)


Put very basically, the difference between the two is that the Server Side
has access to databases and other resources at the server end of the
conversation, but does not have the ability to interact directly with the site
visitor sitting at their client side computer, while the client side
technologies like HTNL and JavaScript are the reverse, in that they can interact
with the user, but don’t have direct access to files, databases, etc.


As the Web matures from its early inception as a document delivery system,
it is becoming much more of a tool for communication between resources and the
consumers and producers of those resources.  For example, in times past an
organization may have gathered information into a central location, entered it
into a computer system to organize and sift through it and then placed the
resulting synopsis onto a web page for the use of those who needed it.

 

By using the Internet as a communications medium between the producers of
the raw information and the central server systems, the middle processes can be
bypassed, enabling the resulting synopsis to be produced in real time, on
demand.  From beginning to end, this is both more efficient and more
usefully productive.


To accomplish this requires much better communication between the client
and server ends of the task, providing a high degree of seamless interactivity
between the user and the databases and resources at the server. 
Technologies like Microsoft’s Dot Net Architecture are designed to shrink the
bridge, as it were, providing a more seamless link.  Technologies like
Citrix’ Presentation Server are designed to enable (among other things) users to
access older programs over the Internet as though they were sitting at the
central server computer.


This type of link also means that the producers and consumers of the
information are not constrained by geography — in other words, their screens
can be any Internet connected computer, so they don’t actually have to go into
an office to do what they need to do.


As the Web continues to evolve, it is my belief that this type of
technology will receive an increasing share of the attention of the development
community, so if you’re planning a career in Web development, you might want to
start looking into them too!



Thanks for reading!

We have had a number of people indicate that their email client programs
are interpreting code examples in this newsletter as actual HTML code instead of
text.  To overcome this problem and to enable everyone to read the
newsletter, there is a period after the “<” in each tag.  If you cut and
paste to try out code examples, please remember to remove the periods. 
Wherever we intend you to use “<.” in your code, the example will show
“<..”.  In this way, you will be safely able to use a global edit to
change “<.” to “<“.  Thanks to all of you for your patience with
this; if this technique creates an undue problem for you however, please let us
know via our feedback address (see Feedback, below).

Q. I’m puzzled: – the text on my web
pages changes size for user preferences, but the headings don’t. Why is
this?


A. Are you viewing your site with Internet Explorer? IE doesn’t allow for
absolute font sizes (pt or px) to change with user preferences — Netscape 6+
and Mozilla do allow it. If you want IE to recognize the font-size user change,
you’ll need to use % or em instead of pt.

Q. I have a web site done in tables
and am trying to convert it to CSS.  Everything seems to work fine except
for my problems of aligning tables within tables.  I finally got everything
to work, but don’t know if the coding is correct. (sample provided)


A. Aligning inside tables can take some experimentation, but you should be
able to get something working by using the text-align and vertical-align css
properties.

Q. I have a piece of Java script I
got off the HTML goodies page to open a new window. It works well enough but
what I want it to do is to run from an onClick event handler. How do I get it to
do this.?


A. You will have to place the window.open into a function and then You can
call the function either by using the onClick or by placing the function call in
the “href”.  Here is an
example:
<.html>
<.head>
   <.title>Open
new window<./title>
<.script
LANGAUAGE=”javascript”>
        
function
OpenWin()
                
{
                 
MessageWin=window.open (“http://www.wsabstract.com“,
“newwin”,config=”location=no,status=no,directories
=no,toolbar=no,scrollbars=no,menubar=no,resizable=no”);
                
}
<./script> 

<./head>
<.body>
<.center>


You can do it this way:
<.a href=”JavaScript:OpenWin()”>Click
here<./a> <.br>Or you can use the onClick
event:
<.a
href=”#” onClick=”OpenWin()”>Click
here<./a>
<./center>
<./body>
<./html>


This is but one example.  You can also set up the function to accept a
variable that contains the link you want to open up in the new window like
this:
<.html> <.head>
   <.title>Open new
window<./title>
<.script
LANGAUAGE=”javascript”>
        
function
OpenWin(linkid)
                
{
                 
MessageWin=window.open
(linkid,
“newwin”,config=”location=no,status=no,directories=no,toolbar=no,scroll
bars=no,menubar=no,resizable=no”);
                
}      
<./script> 

<./head>
<.body>
<.center>


You can do it this way:
<.a
href=”JavaScript:OpenWin(‘https://www.htmlgoodies.com’)”>Click here<./a>

<.br>Or you can use the onClick event:
<.a href=”#”
onClick=”OpenWin(‘https://www.htmlgoodies.com’)”>Click here<./a>
<./center> <./body> <./html>


This will allow you to use the same function for multiple links.

Q. My site uses 3 frames, heading,
links and the third is the body, which is the only thing that changes as you
move through different parts of the site.  I’m using css for fonts, colors
and background images on the site. I would like to use a watermark logo, but I
do not want to show it in the heading or links frames, only the body. Is there
some way to override the background image in the css file in my heading and
links frame so it remains as just a white background?


A. Put a class=”withbg” in the body tag of your BODY.
Put the background
declaration in body.withbg {background-image….}

Q. When clicking on a selection, it opens the new page in a new
window.  How do I get the script to open the page in the same window?


A. If you remove the target=”_blank”  in each link it will open the
document in the same page.

User Tips: Calculate the Date After a Given Number of Business
Days


An issue came up recently where a client needed to wait a certain number of
business days before taking an action. In particular, they wanted to know, given
a certain date (such as today), on what date should the action be taken if we
must wait 15 business days. A business day is defined as any weekday that is not
a holiday.

AutoPostBack ASP.NET Sample Code


After publishing our ASP.NET Flex Table Sample last week, I was surprised
that the part of the code which I received the most questions on was that the
form posted back to the server automatically whenever the value of the drop down
list was changed. I wish I could take credit for it…
