Adding 3 Different Random Numbers For Blackjack / 21?
Oct 19, 2009
I would like to create a Blackjack style game for one of my high school programming classes. I can generate 3 different random numbers and use these random numbers to display an image with that number on it.
How do I add the 3 separately generated numbers together to show the total??
Here is my code so far. Specifically I would like to add the myNumber1(), myNumber2() and myNumber3() results together.

I'll get to the point, I'm a noob I'm using greasemonkey for a certain website. Basically, I'm using gm to refresh the page after a certain time, I was however wondering, If I can set it to a random number between 2 specific times?
The code I'm using atm is setTimeout(function() { document.location.reload(); } , 10000); I know I have to use math.random, well, I think I do. But I'm not sure how to do it between 2 certain times? So to summarise, I'm trying to refresh a page at any given random time between say 5-10 minutes.

This script is a slightly modified version of "Unique Random Numbers". In this script it becomes easier to implement more than one instances of "Picking Unique Random Numbers".
This JavaScript picks up a number of unique random elements from an array.
For example; if you have an array myArray consisting of 10 elements and want to pick 5 unique random elements. Suppose initially myArray[3] is picked randomly, then myArray[3] should not be picked again.

My Name is Tom I am from the UK and I am (for my own entertainment and learning) creating a dvd indexing web application to sort and catagorize my dad's dvd collection. On the homepage for this website I have dynamically (using JS) appended 3 image elements which contain the images of dvd box art at "x by 225" pixel dimensions i.e. when I resize the dvd box art they all have to be 225 pixels in height and constrain to the necessary width in contrast to the height. Now that the images are working, I now want them to be randomized so 3 unique box art images are displayed everytime the page is refreshed. So far my script is:
Code:
// Image Rotation Javascript
function imageRotation()
{
// Preload images
[Code].....
Problem with this is that sometimes I get results from the random number generation that are non-unique i.e. sometimes random_number1, random_number2 and random_number3 yield: 3,3 and 11 etc. I need to make it so that you never get such clashes or it will show 2 or more identical images on the homepage. How can I change the random number generators to achieve this?
how to plug the imgObj into the image elements as to use the preloaded images instead (at the moment their just hard coded.)

I have a form wich has a add/remove row button, this so the visitor can select multiple sets of data. All is fine and is being submitted via PHP.
Only problem is from number 10 and up, i am getting strange random numbers in the new rows that are added in their name. Like 1111 (instead of 11), 122222 (instead of 12). And because of this, every row from 10 and up won't be send through php, giving this random effect.
The full form can be viewed: [url]

I have a quick question with multiple array and random numbers. If i generate my random numbers in one array, how would i take a selection of those numbers and put them in another array?
Ex: array 1: 25, 34, 38, 40, 22, 49
Want to move numbers between 30 and 50 to another array.
array 2: 34, 38, 40, 49
Is it as simple as for loops and if statements setting the conditions? do i use a sorting method? (selection? bubble?)

I am trying to create a javascript code in which I prompt the user for a number (an integer from 0 to 100) to search for, then search a function with the number they entered and then display whether the number was found, and if found, a location where it can be found within the list.

I've got my code, and the task is to generate two random numbers, the user then inputs an answer for them added together, then the program checks the answer and displays either "correct" or "wrong". Here's some of my code:

response = "correct";
} else {
response = "wrong";
} document.questions.result.value = response ;
} function randoms() {
rndNum = Math.random();
Num = rndNum*20;
Num1=rndNum*10
document.write(Math.round(Num)+"+"+ Math.round(Num1));
} function adding() {
document.write(Math.round(Num) + Math.round(Num1)); }

I'm trying to generate random numbers 0-8 to use to access array indices.[code]Every once in a while, I'm getting a -1 in my console log. I read on a site that this line:[code]will generate a number between 0 and 10 (so 1-9).How is -1 being generated?

I'm trying to do a homework problem that involves using cookies to add numbers.
Here is what I've done so far:
The code is simply supposed to prompt the user asking how many numbers he/she would like to add. Then it is supposed to have additional prompts asking for each individual number. As the numbers are being inputted, it is supposed to keep a running sum via cookies and then output the total at the end.
The problem that I'm having is that I don't think the cookies are even being created which is weird because the createCookie(), printCookie(), and overWriteCookie() methods are copied directly from the textbook.

I have an HTML form, that's part of a child window,and has two random numbers in it. How can i have it so when user inputs the sum in an empty box in the form, and clicks 'submit' the result is displayed in the main window? Also, it needs to check if answer is correct or wrong and show that in the main window at the same time.

I have the following code that I wrote myself (except for the function isNumberKey). However, I don't know how to actually add the numbers together. My plan is to store the value entered in the forms as a variable, then manipulate the variables to get my final number. The final number would be stored in variable named Total and would be displayed after Total: at the bottom of my page.

I'm wondering how I can add numbers in real time using javascript.
example,
say I enter a number in a text field,
<input type="text" name="qty" value="2">
<input type="text" name="cost" value="5">
how would I then be able to get the total in another test field, like:
<input type="text" name="total" value="10">

On my website, I have random logos appear on the home page as products that I recommend. I would like to make these logos into links to the website they are from, so that when one clicks on the picture, it directs you to the site, but I can't quite get it to work, and I know very little about Javascript (as you may know from my previous question about Javascript).
Here's my current JS code:

I am trying to figure out how to make an online quiz via Javascript, based on just a couple questions (4 to be exact) from a question-bank, and I want only 2 of the questions out of the 4 to appear when the quiz is taken (randomly of course).I found a great template online for what I want my quiz to look like, however, it does NOT have the random add-on functionality I would like.I am not looking for the 'answer' or for someone else to do the workHere is the quiz template I found:

I have a pretty basic HTML form, it doesn't go to a database or anything, it just gets emailed directly to the owner of the website with their customer query.However, the owner has now asked that each query be assigned a random reference number of no more than 16 digits which must also be visible to the customer.I presume this will be relatively easy but I'm a complete beginner with Javascript which I assumed would be necessary for generating the number. I've sort of figured out how to generate the number but I can't figure out how to get that number into a read-only field on the form so that it will be both visible to the client and sent with the rest of the data on the form to the owner.I've had a number of attempts but this is what I'm trying at the moment:
