A successful
launch of an Ajax based application does not mean the developer's work
is done. There will be bugs, upgrades and other user concerns that
should be addressed immediately. It can even get worst if the
application were not made to deal with large number of users or if the
application was not secured enough.
Before you launch your application, here are some ideas on how you
can ensure ease of access for users. These ideas will also improve
security and possibly detect bugs that were not found during the
testing phase:
1. Check for Question Mark and Ampersand
The question mark (?) and ampersand (&) are two essential
symbols in the function that should never be left out. Although this
type of problem can be easily detected in functions, the use of these
functions as data might not be detected. The ampersand might be
interpreted as data. Be sure to double check the use of these symbols
especially on email and name parameters. The question mark and
ampersand have to go together.
2. Get Additional Firefox Tools
Every developer who uses Firefox as their main browser will most
likely use Firebug to aid the debugging process of their application.
Through Firebug, the common problems in coding can be detected and
recommended solutions can be easily found online.
But you don't want to be stuck with Firebug especially when you're
building a unique widget or data intensive online application. Visit
JSLint.com so that you'll find out more about your coding. Through
JSLint, your code will be validated against other browsers. It's simply
frustrating for many developers when their application can easily work
in one browser but fails in another.
3. Working with Parameters During Testing
Testing will require developers to take a look at every function,
data source and parameter in the application. But its parameters should
be emphasized in the testing phase because of its potential as a
separate testing tool for Ajax and JavaScript. When done right, the
parameters can push the application to the limit to determine its true
capabilities. The two parameters: GET and POST should aggressively use
the server side which means these two parameters can push the server
side just to retrieve the needed data.
4. Avoid Problems in URL Set-up
Sometimes the biggest problems were caused by the simplest coding. A
good example of a disastrous application with a small cause is from URL
structuring. Developers have to double check on how they code the URL
so that the JavaScript engine in various browsers will understand the
data as URL. As already indicated, the question mark and ampersand have
to be emphasized.
5. Checking the Outcome from Server-Side
The server-side constantly crunches out the needed data in Ajax and
JavaScript based application. The data, before interacting with the
client side, should be at least checked for accuracy.
This might require additional time for developers but ensuring
accuracy will prevent further problems. Developers will be able to
build an easy to use application that constantly provides the right
data.
