Using Microsof Front Page, I am trying to display the time on the
Status Line, however, to no avail.
Here is a snip of the code code:
...\dev\JavaScr ipt\DisplayTime InStatusLine.js
<HTML>
<HEAD>
<script type="text/javascript">
//This function displays the time in the status line
//Invoke it once tho activate the clock; it will call itself from then
on.
function DisplayTimeInSt atusLine(){
var d = new Date; //Get current time
var h = d.getHour; //Extract hours: 0 to 23
var m = d.getMinutes(); //Extract minutes: 0 to 59
var ampm = (h >= 12)?"PM":"AM"; //Is it am or pm
if(h > 12) h -= 12; //Convert 24-hour to 12-hour
if(h == 0) h = 12; //Convert 0 o'clock to midning
if(m < 10) m = "0" + m; //Convert 0 mins to 00 mins,etc
var t = h + ":" + m + ' ' + ampm; //Put it all together
defaultStattus = t; // Display it in the status line
// Arrange to do it all again in 1 min
setInterval(Dis playTimeInStatu sLine(), 60000);
}

Can anyone help?

It is a convention that only constructors start with a capital letter,
so make that:
function displayTimeInSt atusLine(){
var d = new Date; //Get current time
You want to call Date as a constructor function, so add '()':
var d = new Date();
var h = d.getHour; //Extract hours: 0 to 23
getHours() (note the 's') is a method of a date object, so it needs ()
to call it:
var h = d.getHours(); //Extract hours: 0 to 23
var m = d.getMinutes(); //Extract minutes: 0 to 59
var ampm = (h >= 12)?"PM":"AM"; //Is it am or pm
if(h > 12) h -= 12; //Convert 24-hour to 12-hour
if(h == 0) h = 12; //Convert 0 o'clock to midning
if(m < 10) m = "0" + m; //Convert 0 mins to 00 mins,etc
var t = h + ":" + m + ' ' + ampm; //Put it all together
defaultStattus = t; // Display it in the status line
// Arrange to do it all again in 1 min
setInterval(Dis playTimeInStatu sLine(), 60000);
The first argument to setInterval should be a string. Your function
will execute displayTimeInSt atusLine() zillions of times per second -
but you will only notice that your browser runs slowly. All the CPU is
being sucked-up by calls to DisplayTimeInSt atusLine():
setInterval('di splayTimeInStat usLine()', 60000);
Incidentally, that will likely slowly drift off the correct time so that
it is either + or - 1 minute from the 'correct' system time - say you
start it one second before 3:05 pm, it won't call the function again
until one second before 3:06, so when it shows 3:06 it will be 3:07.
But in any case, many browsers (including mine) will not let you change
the status bar text with script, so you've totally wasted your time -
but hey, for the purpose of the demo...

syntax error. The only thing that goes in the external file is script
code, no tags. But you will still get an error unless you made a mistake
in your copy/paste. Your script tag references .\JavaScript... . but you
say it is in .\dev\JavaScrip t\... Those are not the same paths. And IE
will use a standard 404 page for the script source and again generate
errors.

Thanks for your prompt response Randy,
the tree directory looks like this

......
When including the *.js, I used relative address

<SCRIPT SRC="JavaScript \DisplayTimeInS atatusBar.js"></SCRIPT>

I don't see a problem with this statement, however, I have been proven
wrong more than once.

That is not what you posted the first time though. But even then,
..\JavaScript and JavaScript are not the same path. For testing purposes,
put your .js file in the same folder. Resolve any and all errors, then
move it to the folder. Then, if you get errors you know it is a file
reference error. Is that the way your file is named as well? When
testing locally IE doesn't care about case, it will matter on a live
website though.

Which issue? The path issue? If you give a src attribute an improper
source file, then IE will get a "404 Page not Found" file and insert it
in the src since it can't find the file it was hunting. And since the
first few characters of that file are <html, it is a syntax error in the
script block.
And yes, you are rihgt! I still get the runtime error!!
Runtime Error or Syntax Error?
