I have this code for figuring out whether a given number is prime or not:
var SMALLEST = 2;
var BIGGEST = 9E15;
var n = prompt("Enter a number and I'll check if it is prime");
if (isNaN(n) || n < SMALLEST || n > BIGGEST || n % 1 !== 0) {
alert("I can only test integers between " + SMALLEST + " and " + BIGGEST);

i have a a script for typing speed test. after 10 sex. script shows some result like Raw CPM: 35 Corrected CPM: 20 WPM: 4Time left: 0 Your score: 20 CPM (that is 4 WPM) In reality, you typed 35 CPM, but you made 3 mistakes (out of 7 words), which were not counted in the corrected CPM score.
[Code]..
I'm not too experienced in programming, all I know is from practicing so don't be surprised if I made some mistakes. One mistake that I know is that the page is absolutely non-standard, but I don't really care about things like web-standards when making these little scripts.
As I'm Hungarian and not English, this code (functions, vars) was also written in Hungarian, but I translated it to be a bit more readable for Englishpeople. If it's still not clear, I can comment it.

I'm using the standard module pattern and the problem is once you set a private variable, trying to test that object independently becomes a nightmare as the next test is polluted by the actions of the previous.So, the options are to have some reset method (which is horrible), setters on everything (defeats the point) or delete object and re-load script (hideous).

while (n < 10001){
if (x%primes[n] == 0){
x = x + 2;
}else if ((n + 1) < (primes.length)){
n = n + 1
}else{
primes[(n+1)] = x;
document.write("PRIME#" + (n + 1) + "= " + primes[(n+1)] + "<br />");
x = x + 2;
n = 1

Now the problem is that somehow this code also interprets some non-primes as primes.

Ive been having a problem of late with one of my sites that uses PHP5 /
Ajax. The problem is that periodically the ajax functions lock up and it
gets stuck in the loading phase of the request. If i restart the apache
server everything goes back to normal (i assume it severs the connection
to the ajax called function).
I think this is a problem with the javascript part as i have tried it
using a straight post request and have have no problems and slow loading
time is localized to the one user (ie. still works fine on the other
computers on my office network).
I have recorded this happening in Firefox, safari and IE6 & 7
My server is running debian with apache2 and php5
Just wondering if somebody can shed some light on what my problem may be? Code:

Now I'm using JQuery in a couple places, but it's by no means nothing crazy. The page is fairly simple.
I thought of preloading the main content images, but even after they are loaded in the cycle, the loading time is still slow.
I read somewhere that putting Javascript code after CSS code on webpages makes them feel like they load faster. I was wondering if any of you has any experience with this and if you do follow this rule in your projects.

I have to move 2 layers (one from up to center and one from bottom to
center) and I found this way:
<div id="up" style="position:absolute;left:10px;top:-20px">Up</div>
<div id="down" style="position:absolute;left:10px;top:200px">Down</div>
function movediv(){
var u = document.getElementById("up")
var d = document.getElementById("down")
u.style.top = "100px";
d.style.top = "100px";
}
It doesn' work...because:
1) They don't move at "the same time"...I would like to obtain
simultaneous move.
2) I can't control speed so moving is invisible!
I'm using the following to allow dynamic resixing of an image (when the usre

Suppose I want to populate a drop down ajaxly. The population is written like:
var $select = $("#target");
$.each(datas, function(){
$("<option/>")
.val(thia.value).html(this.name)
.appendTo($select)
.data('srcData', this);
});
But the speed is considerably slow when the datas is large. I know that I can use just string concatenation and html() finally to speed it up but what can I do with the data()?
I'm trying to create a button that will increase and decrease the var speed variable

I'm justing wondering about the behavior of JS in regards to adding elements, suppose I have something like this:
I'm just wondering at the point I hit that "// DO SOMETHING WITH ONE OF THESE DIVS", are all the divs I have added in the DOM available to access?
I ask because I have some code at work in which a tester is reporting an error that happens which I can't reproduce, and they and others have had it a few times.
The only way I can explain it in my mind is if the div is not available to me at the time of execution. So I'm just looking to rule it out or confirm my hunch.
Is document.getElementById("myDiv").appendChild(obj); synchronous and the next line of code wont execute until the DOM is ready or is it in fact a asynchronous call and therefore adding alot of elements to the DOM could result in a lag so some divs or not available straight away.
