on-the-fly
messages
Text inside the
document is usually static- if you reload this document 5 times, there's
no reason to believe that the document's text will be any different each
time...or is there? One of the coolest things about JavaScript is that it
allows you to generate text on the fly. You could, for example, have the
document greet you "Good morning" in the morning, and "Good
night" at night. The basic way to write out text in JavaScript is by
using the document.write() command, as follows:
<script>
document.write('Some text')
</script>
Whatever you put
inside the parentheses, JavaScript displays it on the page. Taking this
basic idea one step further, I'll create a script that writes out the last
modified date of this page.
<script>
var modifieddate=document.lastModified
document.write(modifieddate)
</script>
08/07/2001 02:26:24
The above is a perfect
example of "on-the-fly" text. The text reflects the last
modified date of your page, and is updated automatically whenever you edit
the page and save it!
