AJAX is short for Asynchronous JavaScript And XML.
</p>
<p>
Basically
AJAX means you can reload parts of an HTML page without reloading
the whole page. This makes it possible to create a faster and
nicer feeling website or web app. It takes less time to generate
the HTML for a part of a page than regenerating the whole page.
It also takes less bandwith as there is less data to transport.
Refreshing only part of a page can also reduce the blinking
of web page refreshes.
</p>
<p>
Try clicking the links below to change the lower of the two
texts on the right.
<br/><br/>
<ajax:link targetElement="linkElement">
<a href="data1.jsp" >Click to change to text 1 using Ajax Tag</a>
</ajax:link>
<br/>
<ajax:link targetElement="linkElement">
<a href="data2.jsp" >Click to change to text 2 using Ajax Tag</a>
</ajax:link>
<br/>
<ajax:link targetElement="linkElement">
<a href="data3.jsp" >Click to change to text 3 using Ajax Tag</a>
</ajax:link>
</p>
<p>
As you can see the main page doesn't refresh. To prove this look
at the time stamp at the bottom. That time stamp changes whenever
you refresh the whole page.
</p>
<p>
Last refresh: <%=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date())%>
</p>
