I think you should have a look at the three top articles in the search below:
http://www.codeproject.com/search.aspx?q=snooker&x=0&y=0&sbo=kw[^]
In any case you should use vector calculus to calculate the angles as well as the elsatic collition. The Angles would be dependent on the incoming vector and the deviation should be from this line of reference. I know that the code is written in C# but I think you should get the understanding of the physics.

I m using the below code.But my page is taking much time to render.I m APS.net developer .Please suggest me solution.
function GetRecord() {

dataType: "json",
success: OnSuccessCall,
error: OnErrorCall
})
}
function OnSuccessCall(response) {
$j(document).ready(function () {
var xmlDoc = $.parseXML(response.d);
var xml = $(xmlDoc);
var tblcalendar = xml.find("Report");
$('.tbl_calendar').html('');
$.each(tblcalendar, function (index) {
var row = "<tr>";
row += "<th>" + $(this).find("Month").text() + "</th>";

I’m trying to get my website to show images one after the other using java script I got from www.javascriptkit.com/howto/show2.shtml and have followed there example as closely as I can but with no luck.
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<title>Acrele - Home</title>
<meta name="keywords" content="" />
<meta name="description" content="" />
<link href="CSS1.css" rel="stylesheet" type="text/css" />
<script type="text/javascript">
var image1=new Image()
image1.src="16.jpg"
var image2=new Image()
image2.src="employee-training.jpg"
var image3=new Image()
image3.src="Real_Estate_Investment_Education.jpg"
var image4=new Image()
image4.src="Unti2tled.jpg"
var image5=new Image()
image5.src="Untitled.jpg"
var image6=new Image()
image6.src="zclassroom.jpg"
</script>
</head>
2. Added the html code were I want the image to show:
<div id="left-feature-colum">
<div id="slider-bg">
<div id="slider">
<img src="16.jpg" id="slide" width="600px" height="300px">
</div>
</div>
</div>
3. Edited there javascript accordingly to the number of images I’m using:
<div id="left-feature-colum">
<div id="slider-bg">
<div id="slider">
<img src="16.jpg" id="slide" width="600px" height="300px">
<script>
var step=1;
var img = document.getElementById('slide');
img.src = "image" + step + ".src";
console.log(img.src);
if (step < 6) step++;
else step = 1;
setTimeout(slideit, 3500);
</script>
</div>
</div>
</div>
This isn’t working, it only load the first image “16.jpg” only…Help

You have removed the code from inside the "slideit" function, so now there is no way for it to repeat and the setTimeout(slideit, 3500) is trying to call a function that doesn't exist.

There are a lot of bad slideshow scripts out there, I rewrote one that was a CMS plugin for word press which had many errors in it, and made no sense to me. It might be too advanced for you, and requires JQuery, but is simplistic in design.

Off by one error - range of random 0-12, valid range for Array 0 - 11
Removed an unwanted comma (,) after rec[q] in your document write.

for(var i=0; i<12; i++) {
document.write(rec[i] + ",");
}
document.write("<BR>");
for(var z=0; z<6; z++) {
var q = Math.round(11 * Math.random());
document.write(rec[q] +", "+ z +" ");

Well.. now how do i prevent adding the numbers of array elements value, array elements only among themselves, I just wanted to combine random..
Output is:
19, 0 23, 1 20, 2 19, 3 34, 4 45, 5
it must be:
19, 23, 20, 19, 34, 45
Why does it wrote the numbers of random array and how do i prevent the same number selection..¿
Quickly remove the shameless

I have to special thanks for all ur helps.

Well you aren't putting the (value of) the z variable into the array. Only showing its value.
remove the
+ z +" " from document.write

I tried the following lines at least.. have you got an idea about this statement?
document.write("<BR><BR>" + "Combination is :" + "<BR>");
do(q) { z += 1;
var q = Math.round(Math.random()* 11);
if(q==q) {return q;}
document.write(rec[q] +", "+ z);
} while(z==6);
|
|
|

Is there something to way some simple code to do this?
|
|
|
|
|
replace with this.
<script>
var taken = new Array(49);
for (var i=49; i>0; i--) taken[i]=false;
var lucky = [];
var rec = ["19","20","21","40","41","45","12","23","34","36","37","46"];
document.write("Weekly records for 2 week : ");
for(var i=0; i<12; i++) {
document.write(rec[i] + ",");
}
document.write("<br><hr>");
var z=0;
do {
var q = Math.round(11 * Math.random());
if(!taken[ rec[q] ]) {
lucky[z] = rec[q];
taken[ rec[q] ] = true;
document.write(lucky[z] + "<br>");
z++;
}
} while (z < 6);
</script>
this line:
if(!taken[ rec[q] ]) checks if NOT taken (! = not)

Excellent code thanks a lot.
|
|
|
|

Just letting you know what your errors here are. See my other post for new code.
do(q)
can't use expressions at the top of do loop *(q)*, just use
do {
z is not declared with var *and* initialised with a value. var z = 0;
z +=1;
you don't need the { } braces for a single statement..
if(q==q) return q;
but, q==q just evaluates to true so you might as well have just written this
return q;
I am not able to reply very quickly. On a training course for another 10 days. Be patient.
Please keep trying to write new code as it is easier for me to guess what you are doing.

Finally, ask you for anything more in a array of 12 elemented to 49 membered Argument want to match, you can also help me in this topic? JavaScript writing is so hard really. Thank you for your help.
I tried the following lines:
var arrNumbers = [49];
var arrOutside = [];
var arrInside = ["19","20","21","40","41","45","12","23","34","36","37","46"];
var z=0;
for(var i=0; i<12; i++) { arrInside[i]=false; }
for(var j=49; j>0; --j)
{
arrNumbers[j]=j;
if(arrNumbers[j] != arrInside[i]) {
document.write(arrNumbers[j]=arrOutside[z], + ", ");
arrInside[i] = true;
z++;
}
}
if this is what special things I did not want to deal with it..
I do not want to discuss whom it is could not be shy

Please explain what inside & outside mean.
inside what?
outside what?
arrNumbers = [49]; // array length = 1 ???
I'm guessing this is what you intended
arrNumbers = new Array(49);
Also, you can't assign (=) inside of document.write()
arrOutside[j]=j
arrNumbers[j] = arrOutside[z]
did you mean to show arrNumbers and arrOutside, or copy from one to another?
this does not make sense.
arrNumbers[j] && arrInside[i] = true;
What other programming language do you know?
Because, it might be easier if you write your code in a computer language that you are familiar with.
I will be able to figure it out.
