This is a demo of a script which announces a weekly meeting (in this case, Wednesday at noon): nextwed.htm if that helps.

This might give you some ideas:
function readRadio(parm) {
var sel = document.getElementsByName("S"+(6-parm));
for (var i=0; i<sel.length; i++) {
if (sel.checked == true) return i;
}...

What have done so far? Did you get any clues from the textbook, handouts, or lecture?

I didn't solve the problem, just evaded it. The Principal-Interest (P.I.) window now has line numbers which can be used (after closing the window) to initialize the original screen with the...

Or let the computer do even more work:

var dayname = new Array ('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday');

I have a mortgage calculator which can produce the following table when "Gen P.I. in new window" is selected (options were 20,000 at 5% for 6 years):

One of my early pages (no forms or table) called a function that wrote the time difference as document.write()s. The body contained

That's a lot more concise than what I ended up using
if (typeof(noteLength) == "undefined")
return -1; Thanks for the input.

I have the following function in various related pages:

function getNoteLength(notelet) { // Returns duration of note , whole = 768
var NoteLengths = { "16th":48, "32nd":24, "4th":192,...

Something like this should work:

result = "tumblr_mgn6mfe9aD1rbaz5bo1_500.jpg (500×705)".match(/.*\((\d*)×(\d*)\)/
if (result != null) {
var picHeight=Number(result[1]);

hello all,

I'm working on a website crust sins,

I want a menu like www.ubuntu.com.

My first line should have read: result = valueFromATextArea.match(/(\d*\.\d\d)\D*/)

The last slash was needed to terminate the regular expression.

result = valueFromATextArea.match(/(\d*\.\d\d)\D*)
if (result == null)
alert("Insert appropriate squawk here");
else
var theNumberIWantToLookAt = parseFloat(result[1]);

/(\d*\.\d\d)\D*/ Should do it. You can take result[1] to parseFloat to read it.

You could run a **.style.visibility = 'hidden' command from a (body onload=***) or, if you have other things to do at startup, in a function theonload kicks off. I often have something like ...

I think you don't need to add 1 to your random number to keep it in the range 0-9.

var row = Math.floor(1+Math.random()*10);

You might want to pick 10 random numbers from 0-99 and use those to...

Never mind. Just discovered I forgot new in these lines:

sumMeasure = 0, sumBatch = 0;
for (var iU=0; iU < lineU.length; iU++) { // Initial processing loop on upper staff.

I am trying to upgrade a working page to use an array of objects. The existing page is spacepart.htm and am working on spacepart1.htm.
This is a sample of what's new:

Well, what is your question? FWIW mortgage.htm, will crunch the numbers if you know how much the loan is for, the interest rate, and length of the loan. It can't help with any service charges,...

It looks like the fields populated by getElementById don't get executed until "submit" has been clicked so the Blur functions never get run with the latest data.

All of my JavaScript thus far has been as part of a webpage, but have been encouraged to create "tools" where text is provided to a function as a parm from "StdIn" and returned to a StdOut. This is...

I hadn't thought of doing a test in that order, but I'll have to keep that in mind for the future, thanks for looking at it. It worked when I checked for null so I uploaded it to spacepart.htm. ...

Never mind. I am now checking for null rather than an empty string.

In something to read clipboard data from a music notation program, I am not interested in a note if it has the Grace attribute, stem direction is missing, or spacing has already been applied. The...

You're welcome, but make sure you are a lot further along before coming to this forum. This should be the last resort, not the first. Someone on a programming forum I used to visit was notorious...
