JavaScript - Creating A Slideshow Program
Hey everyone, I am writing a Javascript program which requires several different functions to be assigned to buttons, and an array created as the source of images in the program. I have written/looked at/worked on it for hours and hit a wall. Can't make heads or tails of it anymore, and I would really appreciate any insight on where to go or points of weakness in my code! If anyone is willing to help me out, let me know and I will post.
Again any help or knowledge would be MUCH appreciated! Similar TutorialsHi, I have to create a simple program in javascript (temperature converter) but without the use of functions. The other parameters in this are that: It creates a prompt asking the person if they want Fahrenheit -> Celsius or Celsius -> Fahrenheit It then has another prompt asking what temperature they'd like converted Finally, the output has both the original temperature and the converted one. Also it was noted that I had to use IF statement to guide the "flow of the program." I've been having a lot of troubles with it, as I do not know how to create a program without the use of functions. I'm also having issues with figuring out how to program it so the program knows that the user picked Fahrenheit to Celsius/Celsius to Fahrenheit and prompts them about the temperature they'd want changed. Any help/guiding would be great. Thanks. I would like to create a slideshow like what most wedding sites have but I would like to have some fancy transitions like "Random dissolve, checkerboard, spiral" e.t.c, how can I add any of those to my slideshow, this is a regular fade slideshow I have: Code: var speed=40; /* this is the image fade speed - higher value=slower, lower value=faster */
var timer=4000 /* this is the time that each image is static - 4000=4 seconds */
var pics=new Array();
pics[0]='images/autumn.jpg';
pics[1]='images/lace.jpg';
pics[2]='images/lotus1.jpg';
pics[3]='images/lotus.jpg';

I've found many examples of creating slideshows using javascript all over the internet and these forums. However, I haven't found any that show how to create a slideshow and give each slide a different time interval between switching to the next one. I'm changing my website over from a Flash based one to something that can be read on all devices. In doing so I've looked for ways to add a little motion to the site. I'm working with a friend who has been doing most of the site but here and there I like to get my hands dirty and try some things on my own. Unfortunately he doesn't know Javascript. I wanted to have an animation window in the bottom corner of the page. Look at http://www.whyreboot.com/blog to see what I came up with. I took a slider plugin for Wordpress and basically created a bunch of slides and entered them in to switch every .5s so that I could change how quickly they changed images by making some of them repeat the same slide 4 times for 2s, 2 times for 1s, etc. Though it's not pretty, it works. On Firefox everything looks great although it'd be nice to have fade in and out on each slide. On an iPad or IE it actually shows the flash between slides even when they're the same image. Quite frankly, it's ugly. Does anybody have any ideas? Please keep in mind that I am a network systems engineer by trade so the only coding I know is Cisco IOS, etc. I'm trying to get this to work in a Wordpress site on a window with dimensions of 450X230. I apologize if this is not the correct place to look for help on this. I have read the forum fules and guidelines and this seemed to be the right place. Thanks ahead of time for any sage advice from what looks like a great community of web geeks! I am looking for tutorials on creating a slideshow with thumbnails, but i need one where i can put the mouse over the thumbnail depending on the direction i am the mouse the thumbnail will move left or right thanks 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 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 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 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'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 get how to save tasks and display the results but I don't know how to calcuate the number of hours. Any suggestions? Here is what I have so far: Code: <!doctype html>

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.

Im trying to write a program that determines if an array is Ragged or not. 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. I wrote about this script a couple weeks ago. I stopped working on it, and just got on it today. Question, what's the easiest way to have it so Monday, tuesday, Wednesday, etc and then the total amount of hours gets added. Code: <html>
<head>
<script language="JavaScript" src="gen_validatorv5-.js"
type="text/javascript" xml:space="preserve"></script>
<script type="text/javascript">
function calc(nForm){
var inHour =parseInt( nForm.inHr.value)
var inMinutes = parseInt( nForm.inMin.value);
var lunchOutHour = parseInt(nForm.lunchOutHr.value);
var lunchOutMinutes = parseInt( nForm.lunchOutMin.value);
var lunchInHour = parseInt( nForm.lunchInHr.value);
var lunchInMinutes = parseInt( nForm.lunchInMin.value);
var outHour = parseInt( nForm.outHr.value);
var outMinutes = parseInt( nForm.outMin.value);
var linearInTime = 60*(inHour)+(inMinutes);
var linearLunchOutTime = 60*(lunchOutHour)+(lunchOutMinutes);
var linearLunchInTime = 60*(lunchInHour)+(lunchInMinutes);
var linearOutTime = 60*(outHour)+(outMinutes);
var workDay = linearOutTime-linearInTime;
var lunchPeriod = linearLunchInTime-linearLunchOutTime;
var linearMinutesWorked = workDay-lunchPeriod;
var hoursWorked = parseInt(linearMinutesWorked/60);
var minutesWorked = linearMinutesWorked-(hoursWorked*60)
if (hoursWorked < 10){hoursWorked = "0"+hoursWorked}
if (minutesWorked < 10){minutesWorked = "0"+minutesWorked}
nForm.timeWorked.value = hoursWorked+":"+minutesWorked;
}

I am 98% done with the Codecademy JS curriculum but I am stuck on this program. Can anyone see the problem? Code: var cashRegister = {
total:0,
//Dont forget to add your property
lastTransactionAmount: 0;
add: function(itemCost) {
this.total += itemCost;
this.lastTransactionAmount = itemCost;
},
scan: function(item,quantity) {
switch (item) {
case "eggs": this.add(0.98 * quantity); break;
case "milk": this.add(1.23 * quantity); break;
case "magazine": this.add(4.99 * quantity); break;
case "chocolate": this.add(0.45 * quantity); break;
}
return true;
},
//Add the voidLastTransaction Method here
voidLastTransaction: function(){
this.total -= this.lastTransactionAmount;
},
};
cashRegister.scan('eggs',1);
cashRegister.scan('milk',1);
cashRegister.scan('magazine',1);
cashRegister.scan('chocolate',4);
//Void the last transaction and then add 3 instead
cashRegister.voidLastTransaction();
cashRegister.scan('chocolate',3);
//Show the total bill
console.log('Your bill is '+cashRegister.total);
Hello I am trying to send some values in combobox2 depending on one value selected in combobox1. Both are in php. Following is the code for combobox1 - Code: <td><div id="Gen_Core">
<?php
$sql="SELECT t.Main_CoNo, t.Main_CoName FROM Main_Course t WHERE t.Modl_No ='2' and t.Main_CoName NOT IN (SELECT t1.Course_Name from Course t1 where t.Modl_No = t1.Module_ID and Student_ID='$Stud_ID')";
$result=mysql_query($sql);
$options="";
while (@$row=mysql_fetch_array($result))
{ $id=$row["Main_CoNo"]; $name=$row["Main_CoName"]; $options.="<OPTION VALUE=\"$id\">".$name.'</option>';
}
?><select size="4" style="width:100px; font-size: 10px;" name="classes[]" id="class_list" onClick="return validateForm()"><?=$options?></select></div></td>
Here is Javascript program - <script type="text/javascript"> function validateForm() { var gen=document.forms["select"]["classes"].value; alert("hi"); } </script> If I select one value from this combobox1, I want to send that value to java script program which is not working...It is not going to Javascript program at all.. I tried couple of things like onClick, onSubmit in form, in select etc. But it seems nothing is working... What I want is - If one option is selected from combobox1, then javascript program should recognize it and send values for combobox2. How will I do it? Really confused..... 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? |
