JavaScript - Need Help With Simple Program
Basically i have an image of a ball that i am trying to make bounce from top to bottom so far it is just going to the bottom and stopping plz help thanks
<head> <title></title> </head> <body> <center> <input type="button" value="Click" onClick="moveDown()"/> </center> <img id="Ball" src="ball.jpg" style="position:absolute; top:100px; left:100px;"/> <script language="JavaScript"> var Image = document.getElementById("Ball"); var Position = 100; var direction = 1; function moveDown() { if(direction > 0) { Image.style.top = parseInt(Image.style.top) + 20+'px'; } if(parseInt(Image.style.top)> 100 || direction > 1 ) direction = 1 if(parseInt(Image.style.top)> 500 || direction < 1 ) { direction = -1 Image.style.top = parseInt(Image.style.top) - 20+'px'; } } setInterval ("moveDown()", 50 ); </script> </body> </html> Similar TutorialsI am very new to coding. The below is an assignment for a class. It is a "game" which is supposed to do the following: When your program starts up it must display the image that will move around, a Start button, a Stop button, and a way for the user to specify an interval before a new game begins. The default interval must be 1000 msec. When the user presses Start, a new game starts and the selected image is displayed at a random place. The image must move to a new random place once per interval. If the user presses the Stop button, the image must stop moving, and a subsequent Start must start everything over from the beginning. Each time the user successfully hits the image, the program must move the image to a new random place immediately (i.e., not wait for the current interval to end). When the user has hit the image 3 times, the program must display a confirm dialog box that reports the elapsed time and that also says something like "Another game?" If the user pushes OK, that starts a new game immediately (no need to push Start again). If Cancel is pushed, the program stops. I have been working on this for hours, but it does not work properly. Obvious issues: the game starts running when the page loads, instead of when the start button is pushed. The confirm at the end does not cause a new game to start. The time/ elapsed time calculations are not functioning properly/ the elapsed time always displays as 1 sec. Code: <html>

I have an homework for a web development class. I wrote a program that would be displayed on a webpage that returns the users zodiac sign.

Quote: import java.util.Random; import java.util.Scanner; public class HighLowGame { public static void main(String[] args) { Random rand = new Random(); int numberOfTries = 0; Scanner input = new Scanner(System.in); char repeat; char ans; int guess; boolean win = false; do { System.out.println("Pick a number between 0 and 10: "); guess = input.nextInt(); numberOfTries++; int numberToGuess = rand.nextInt(10); if (guess == numberToGuess) { win = true; System.out.println("Congratulations you have won!"); } else if (guess > numberToGuess) { System.out.println("Your guess was high try again"); } else if (guess < numberToGuess) { System.out.println("Your guess was low try again"); } System.out.println("The number was " + numberToGuess); System.out.println("You guessed the number in "+ numberOfTries + " attempt(s)"); System.out.println("New game? 1 for Yes, or any other number to quit "); ans = input.next().charAt(0); } while (ans == 1); } } Two questions, why doesn't my program let me keep putting in numbers until I guess the right one? What is wrong with my loop? Pressing 1 should repeat the program, any other number should close. Thanks! I am trying to make a fairly simple program for practicing for a mid-term that is coming up in my intro to programming class and I need some help figuring out how to create the function/setting up the variables. Essentially what the code is, is a program that adds up the values put in 5 text boxes, the values from checkboxes that are selected, and the value of a selected radio button. I do not think I have the variables named correctly, and I have no idea how to create the function. I will post what I have so far so you can get a better idea of what it is I'm trying to make. It's so simple, just adding up everything. I just need help figuring out how to achieve that...

Join Date Feb 2009 Posts 28,311 Thanks 82 Thanked 4,754 Times in 4,716 Posts You forgot the </script> ending tag. Hello everyone. This is my first program. According to the idea of a program that calculates the sum of savings with the bank interest rates that is paid each year. And I put one amount every month. The question is very simple why full = 0? Code: var years = prompt("How many years will accumulate?)");
var prec = prompt("And how many % bank give?");
var income = prompt("How many you will put off in bank?");
var num = 12;
var full = 0;
months=years*num;
console.log("Altogether we get " + years + " years and " + months + " months.")
for (var month = 0; month == months; month++) {
if (month % num == 0) {
full = full + income + (full*prec/100);
} else {
full = full + income;
}
}
console.log("Total accumulated =" + full);

Try... Code: for (var month = 0; month<months; month++) {
Also note that your logic applies the full percentage at the 1st month of the loan/deposit. Is this what your really intended?

on this, Code: for (var month = 0; month<months; month++) {
program started work. But in rusults see this . Code: Altogether we get 1 years and 12 months. Total accumulated =01000100100100100100100100100100100100 all code there Code: var years = prompt("How many years will accumulate?)");

Code: Altogether we get 2 years and 24 months. main.js:17 Total accumulated =2520 But if i write 1 year it dont work,how can i fix it? Code: Altogether we get 1 years and 12 months. main.js:17 Total accumulated =1200 Reply With Quote 01-24-2015, 09:42 PM #6 Old Pedant View Profile View Forum Posts Supreme Master coder! Join Date Feb 2009 Posts 28,310 Thanks 82 Thanked 4,754 Times in 4,716 Posts The value you get from a call to prompt() is *ALWAYS* a string. When you use the + operator with a string, it does *NOT* do addition; it does string concatenation. You just need to convert all those prompt() results to numbers: Code: var years = Number( prompt("How many years will accumulate?") );
var prec = Number( prompt("And how many % bank give?") );
var income = Number( prompt("How many you will put off in bank?") );
Also, you need to do Code: for (var month = 0; month <= months; month++) {
else you will only do (for example) up to month 23 when the user asks for 2 years. Be aware that prompt() and confirm() and console.log() are considered VERY obsolete and should only be used for debugging purposes, not for real web code. I have an assignment to create a program in JS but I have not read JS much more. So, for this assignment, can anyone help me to solve this assignment? Check attachment. Uploaded with ImageShack.us This is my code from prelim to finals. The missing part here is when the input is less than or equal to 65 and greater than 100, the prompt will say INVALID ENTRY. However, after it says Invalid Entry, it must ask you to enter again an Entry until you input a valid entry. It must be terminated after you input from prelim to finals either 0,20,30,40 or after you input a valid entry and after the program calculated it. My program does not terminate after I input valid entries. It just continue to ask grade again and again even it already calculated the grades. I don't know how will I put those code inside the program. I'm getting really confused. Code: <html>

I need a count down clock that will count down 18 minutes and reset itself at the end. also i need a counter that increases by +1 every 18 minutes starting at 0. thankyou I'm very new at Javascript and writing programs so I'm not sure if this is even possible to do. I want to write a program that allows someone to select four tasks from a dropdown menu. The tasks are each 1 hour long. I want the program to calculate the number of hours and display that information below the tasks. I also want the person to be able to add or remove tasks.

I'm fairly new to writing programs in javascript and need a little help with this program. So far I have the following and need to write the program aspect for it. Thanks for taking a look for me. Code: document.writenln("Ragged or not<br />")
if (raggedOr(a))
document.writenln("Array is Ragged");
else
document.writenln("Array is not Ragged");
raggedOr was going to be the name of the function. Im writing this code for a gas station program. I have been writing and improving my code for about 3 weeks now and its quite long. I have about classes , customer class, office class and a gas pumps classes. I need help on how to get started on finding the total output at the end of the day. Conceptually i know what i have to do but I don't know where to begin writing the code. I think each time there is a new customer i should add the amount of fuel purchased to a new total fuel purchases variable in the gas pump class. If any one could give me some advice or tips on my theory it would be great ! Should I create a method or can i be done without one. Code: import java.util.Random;
import java.util.Scanner;

if ((code <= 64) && (code >= 58))

continue;

Hello people CF, I need some help with this Javascipt program that im trying to make. Ill provide you with the algorithm i have made and the javascript code. I only know basic javascripting and i had a lot of help with this. I need help getting the javascript code for comparing last date modified, renaming the copied file with last date modified, also i can get it to copy 1 file, but i need it to loop through all the files in the given folder. Algorithm Code: // get source and destination folder path // check if folder exists // if source folder exists, continue with the process, otherwise display an error message // if destination folder exists, proceed with transferring the files // get the file collections in the source folder // loop through each file to check if the file has been modified // if the file exists, check file attributes to the source file; 32 means file has changed // if file has changed, // compare the last date modified of the source and destination file // if the source last date modified is greater than the destination last date modified then // rename the destination file by appending the last date modified // to its file name and then transfer the lastest file from the source folder // otherwise, no need to copy the file and move to the next file // otherwise, do nothing and move on to the next file // otherwise, create a folder first before proceeding with transferring the files I had a lot of help with this Code: <HTML>

im looking to make a program for my site to where somebody can type something in and it will go onto a image like a userbar and then they can save that image with the txt the choose to go over it, does anybody have any advice for me to use? <script type="text/javascript"> var myString = "zero one two three four"; var mySplitResult = myString.split(" "); for(i = 0; i < mySplitResult.length; i++){ document.write("<br /> Element " + i + " = " + mySplitResult[i]); } </script> "split" function splits the string whenever it encounters "space". But please explain me how the strings are stored in "mySplitResult". And can we use Arrays for this program? If so, can you code it. Thanks in advance! Hi, I'm very new to programming, and for practice I tried to build a program that calculates a golfer's handicap based on the course they played and their score on each hole. The program is designed to cap a golfer's score at 2 over par. For some reason, the program works when the hole scores are at least 2 over par, but not any other time. Would someone mind taking a look at the code below and letting me know where I went wrong? I appreciate the help! Code: //Program designed to calculate golf handicap
//based on couse and scores on every hole.
var course = prompt("What Course?");
if (course === "Seneca"){

total += score[i];}
//Calculating handicap
var a = (total - rating);
var b = (a * 56.5);
var c = (b / slope);
console.log(c);
what does this code mean "obj.to"? The code is here - Code: clearTimeout( obj.to ); I just want to know what does "to" mean here? |
