I used Google and found some references for integer in Java.
But "int" not only does not work, it also prevents reading X and Y
coordinates of the mouse.
What i would like to do:
1) Get X and Y mouse coordinates into a variable that i can do real math on.
So far, i can do math on the values "read" and that result goes into
a "variable" that is useful *only* for display.
If i try "int" in that math, the values are then zero for everything
- even those where i do no calculation.
2) Use the calculated integer values as an index to a table or array.
It is acceptable to use an HTML "table" as the source for the lookup;
W(CalcFromX) and P(CalcFromX) would be the resulting values to be
displayed on the screen somewhere.
Can this be done, and eXactly how?

How are you trying to read the coordinates? It sounds like you are
trying to write JavaScript using Java documentation. Recognise the
distinction between the languages and you should find it much easier to
find the documentation you need.

There is no 'int' type in JavaScript. Variables are typeless, their values
have types. Reading mouse co-ordinates is done by accessing the properties
of a mouse event. You can read about events at Quirksmode:
<URL:http://www.quirksmode.org/js/introevents.html>
What i would like to do:
1) Get X and Y mouse coordinates into a variable that i can do real math
on.
If you are looking for the co-ordinates of a mouse click, try this from
Quirksmode:
function doSomething(e)
{
var posx = 0;
var posy = 0;
if (!e) var e = window.event;
// W3C compliant browsers
if (e.pageX || e.pageY) {
posx = e.pageX;
posy = e.pageY;
// MS IE compliant version
} else if (e.clientX || e.clientY) {
posx = e.clientX + document.body.scrollLeft;
posy = e.clientY + document.body.scrollTop;
}
// posx and posy contain the mouse position relative to the document
// Do something with this information
}
Call it from a body click event:
<body onclick="doSomething(event);">
So far, i can do math on the values "read" and that result goes into a
"variable" that is useful *only* for display.
If i try "int" in that math, the values are then zero for everything -
even those where i do no calculation.
Without seeing the code, it is impossible to say what is going on.
2) Use the calculated integer values as an index to a table or array.
It is acceptable to use an HTML "table" as the source for the lookup;
W(CalcFromX) and P(CalcFromX) would be the resulting values to be

<title>Click coords</title>
<style type="text/css">
#xx {width: 100%; height: 100%;}
</style>
<script type="text/javascript">
function clickCoords(e)
{
var coords = {x:0, y:0};
if (e.pageX || e.pageY) {
coords = {x: e.pageX, y: e.pageY};
} else if (e.clientX || e.clientY) {
coords = {x: e.clientX + document.body.scrollLeft,
y: e.clientY + document.body.scrollTop};
}
return coords;
}
function showClickXY(e)
{
var e = e || window.event
var coords = clickCoords(e);
document.getElementById('xx').innerHTML = coords.x + ', ' + coords.y;
}
</script>
<body onclick="showClickXY(event);">
<div>Click coords: <span id="xx"></span></div>
</body>
In the above example, the coordinates of the mouse click are passed to an
object called 'coords' with properties x and y whose values are set to the
location of the mouse click.

Not quite true. There is an `int' type, and variables can be strictly

You had trouble because you were using, or attempting to use, a feature
that is not part of the language. Not because of a feature that might be
in a future release of the language unless you were reading a draft copy
of JavaScript2.0 in which case you should have known it wasn't in use yet.

JavaScript is not Java (despite the equal first syllable). Unlike Java
- JavaScript is a loose typed language with current variable type
interpreted based on the current variable value.
Shockwave #2
JavaScript execution environment (where var c = a+b) is completely
separate from DOM (Document Object Model) where say mouse pointer is

Truthfully I am not even sure that your problem is within JavaScript -

There are browsers that follow standards much more closely and fully than
IE (most are already ahead of the yet-to-be-officially-released IE 7), but
none that fully and faultlessly implement everything W3C/ECMA. There
likely never will be.

similar battle will ensue if Google or someone similar ever deliver a
reasonable on-line web application.
Can the Mafia be hired for a hit on M$?
Why bother? Outside their Windows and Office franchises, they are just
another (very well funded) competitor.
Better yet, can a few good programmers be hired to make an OS like
Windows that accepts all the programs that WinQQ without the bloat and
bugs?
The next task would be a decent bug-free browser that follows all of
the standards.
There are browsers that follow standards much more closely and fully
than IE (most are already ahead of the yet-to-be-officially-released IE
7), but none that fully and faultlessly implement everything W3C/ECMA.
There likely never will be.
Well, closer implimentation would be nice, but having thousands of
potential customers complaining to each browser-hostile URL owner (and
taking their business elsewhere) would seem to be even better.

That depends on what you are actually looking for. If it is just typing
values, forget about that in these loosely-typed languages. Any numeric
literal is of type `number' (form control values are string values, so if
you want to do calculation with them, explicit conversion to `number' is
wise).
If it is explicit type conversion, try the unary `+' for all types of
operands, parseInt(...) or parseFloat(...) for string-type operands.
Note that `+' is the most efficient way but not fully backwards compatible,
and that parseInt(...) recognizes prefixes as indicators for a number base
(`0x' for 16; `0' for 8 in some implementations), so you should specify
the base as second operand if you want it to interpret the string in a
certain way. IIRC all of this is described in the FAQ. ... Oh well, apparently the latter. The first thing you have to

If you would develop using a language that implements it, such as
Microsoft JScript.NET (AFAIK server-side only), it certainly would.
** Only interested i client side - *unless* - you know that it would be

That depends on what you are actually looking for. There are image maps
that do not need client-side scripting, and submit the pointer coordinates
relative to the image position to the server; that information could be
evaluated with a server-side script. If you don't mean images, server-side
script cannot be of help obtaining that information (but maybe processing
it).

You cannot do real math without using additional libraries and highly
resource expensive algorithms. In the normal circumstances you are
limited by machine math which may be identical, close or far away from
the real math - depending on values and operations. This is true for

In the context of the given topic the OP's source of frustration is not
clear at all. "Exasperator" because it doesn't support NN4 event
handling mechanics? No one modern browser does it including Firefox.
Or because JScript doesn't have strict type declarations like int, long
or float? AFAIK it is common for all current implementations *in use* -
except JScript.NET (JScript 7.0).

I have tried HTML MAP and it is useful to a small extent; what i
found can only link to another web page OnMouseOver or the like - no
coordinates.
If you know of a syntax or such that will give coordinates, then i
would appreciate learning of such.

Please note the problem with the first 2 display boxes ceasing to
work, and tell me what the he77 is going on.
Once i have a (calculated) year, i would like to "look-up" two
"values" (from a table of some sort): number of wells, and production.
Now those "values" may not be strictly numeric - there is the
possibility of entries like "123,456!" or "83,331#" or "3,551" (no
quotes) and i would want to display or show them "as-is".
Since JavaScript is supposed to be typeless, i would assume that is
not a problem.
The array or table will have about 65 years worth of data.

You've got two fields named "mmX". That's not going to work
the way you want. Give one of them a different name and
assign its value separately.
I will certainly try that; thanks.
However, that does not help explain why it used to work.
I wanted to show mmX in two places, and that is what *did* happen
until recently.
And that *certainly* does not explain why mmY does not work.

This code *used to* work, showing a calculated year in the first 2
boxes; the width
of the second box was made narrow to visually "truncate" the
numbers to integer.
I have no idea as to why they no longer work.
I added "Z value" and *that* works (!!). Go figure.
How can anybody produce working code with that crap happening?

Please note the problem with the first 2 display boxes ceasing to
work, and tell me what the he77 is going on.
Once i have a (calculated) year, i would like to "look-up" two
"values" (from a table of some sort): number of wells, and production.
Now those "values" may not be strictly numeric - there is the
possibility of entries like "123,456!" or "83,331#" or "3,551" (no
quotes) and i would want to display or show them "as-is".
Since JavaScript is supposed to be typeless, i would assume that is
not a problem.
The array or table will have about 65 years worth of data.
Using Google to search for JavaScript, i found http://www.w3schools.com
which seems to give JavaScript help.
Looking in their JS Math, i found "Math Object Methods" with cryptic
numbers ?rating? FireFox, Netscape, and IE.
It appears that *none* of the "methods" work.
One would think that Google is giving bad information, and that site
does not cover JavaScript.

It offers tutorials on a variety of web technologies. Their stuff is OK
but don't treat it as authoritative. It has many eccentricities and is
plain wrong on some things. Use with caution.

The Math object is a native, built-in ECMAScript object. The numbers
for each browser provided by w3schools is the version that supported
that particular property/method.
It appears that *none* of the "methods" work.
As far as I know, they all work in modern browsers. Remember that they
are properties/methods of the Math object, so abs() is used thusly:
var x = -5;
alert( Math.abs(x) ); // shows '5'
Similarly for other methods.

Google is good. Some may agree with your opinion of w3schools, but they
might also be called cynics. ;-)

Does that mean one cannot do a simple-minded y = abs(x) ?

Yes. abs is a method of the Maths object. If you have lots of Math
functions to call, you could use 'with' but it's use is generally
frowned upon because it obfuscates code, e.g.:
with (Math){
alert(
abs(-5) + '\n' +
sqrt(5) + '\n' +
pow(3,4)
);
}
