JavaScript - Repeating Graphic While Loops
some simple stuff ive been stuck on. been trying to get these to come up one after another: set the colour to white
draw a filled circle set the colour to blue draw an outline circle i dont know how to make the loop continue and at each loop carry out on of these instructions? any help appreciated!! var canvas; canvas = openGraphics(); var x; var y; var size; x = 10; y = 10; size = 200; while( size > 0 ) { canvas.drawEllipse( x, y, size, size ); x = x + 10; y = y + 10; size = size - 20; } canvas.paint(); Similar TutorialsHey, I want to create a nice Info Graphic for Web, something like this one: Is possible to do it with JS and style with CSS? Is there any library to generate this graphics and allow to style it with CSS? I've looked at google charts api but I think that I'm not able to style it as I want. Let me know if is there any other solution to create this (without flash). Thanks I have the following code which works fine until I try and display graphics. Please tell me how I could/should display the odometer in graphics format rather than text. I have all the necessary images as .png(0 through 9) in the same folder as the following code. It is just that the text counter displays but not the graphics? Code: <html>
<head>
<script type="text/javascript">
var c=0;
var t;
var timer_is_on=0;
function GraphicOdo(Nommer)
{
d = Nommer.toString();
for (i=0; i<d.length; i++)
{
var image="<IMG SRC=c"+d[i]+".gif>";
// alert(image);
document.getElementById('GraphicCounter').innerHtml=image;
}
}
function timedCount()
{
document.getElementById('txt').value=c;
c=c+1;
GraphicOdo(c);
t=setTimeout("timedCount()",1000);
}
function doTimer()
{
if (!timer_is_on)
{
timer_is_on=1;
timedCount();
}
}
</script>

hello... I'm sorry, i did read the advises, and i've been through the forum, trying to figure out where to look... but i dont know where to find it... so, i'm sorry if my help request will sound silly,,, i'm only looking for someone that will want to point me in the right direction... and i'll try to do my best on my own ... we want to offer personalized tshirts... so we do need a way for the customer to choose size, color, subject and text and check all this in real time... someone that is doing something that we want is http://www.vistaprint.com/embroidere...aspx?xnav=top# in your opininion, is that vistaprint application a java? pls, could you point me in the right direction to understand that? thanks to anyone that will want to help me I have some code that uses a form, and will check it and show an image. If you have/know a script that is simple, let me know! Otherwise, I'm wondering if someone who is proficient in JS/HTML could help me with this task. It's all coded, I just need some help with an error I am getting. Thanks, Blockis Hi, Is it possible to rotate a dial to follow the mouse cursor? I'm trying to recreate this: http://verbdesign.com/hl/rockwell/index.html but would rather it worked like this: http://www.actionscript.org/resource...-II/Page1.html ...but in javascript. Any help extremely welcome. Thanks, Richard Hi I'm new to this and would like some help. I want to display 4 random images and I would like to get them to NOT repeat themselves. Any suggestions? So if image one is randomly selected as "aceclubs.png" I don't want image two to be the same and so on for the other images. This currently the code I'm using right now. I've been duplicating this function with different names for each of the 4 images. However it sometimes produces two of the same image and I don't want that. Code: function random_ace()
{
var cardace = new Array(4)
cardace[0] = "aceclubs.png";
cardace[1] = "acediamonds.png";
cardace[2] = "acehearts.png";
cardace[3] = "acespades.png";
var randomace = Math.floor(Math.random()*cardace.length);
var ace = cardace[randomace];
card1.src=ace
}
Hi guys, Could do with a bit of help! I've found this code elsewhere and am currently using it to load 5 random pages that automatically refresh to another in the array after 10 seconds. This works great. But is there a way of altering this code so it doesn't repeat any of the pages - atleast until it's displayed each page once? At the moment it can display 'page5' 3 or 4 times before I even see 'page2' for example - which is annoying! Code: <script type="text/javascript">
<!--
Array.prototype.random = function () {return this[Math.floor(Math.random() * this.length)]}
Date.ONE_SECOND = 1000;
url =
['page1.html', 'page2.html', 'page3.html', 'page4.html', 'page5.html',]
setTimeout('location = url.random()', 10 * Date.ONE_SECOND)
// -->
</script>
I'm very new to all this, so I aplogise if this is all very obvious! Hi guys. I'm making a webpage for a school project and I need help modifying this timer he http://web.mac.com/rkuhnhenn/Countdo.../Style_3b.html I want it to countdown from 48 hours, and as soon as it counts down, I need it to reset. I need an endless countdown of 48 hours. How can I go about doing that? Thanks guys, your help is highly appreciated. I am very new to Javascript and I am hopeful someone can help me with this issue. I am trying to create a weekly countdown timer that will countdown until a certain date and time in the week (Friday at 4 PM EST). Once that date is reached I would like to have the counter reset automatically and once the date and time is reached I would like to have the counter show the remaining time until the next 4 PM on Friday. I would like to be able to show how many days, hours, minutes, and seconds are left between the current time and set time. I have found some code on this site already and I have started to modify it to try and achieve what I am after but I am running into issues. I can not get my day calculation to work as well as figure out how to change the end date that the timer counts down until. I had thought about calculating the seconds left until that date and subtracting the current time (seconds) from that number to give me a time value, but I'm not sure if that is the best practice? Any help would be greatly appreciated. Here is my code: Code: <html>
<head>
<script type = "text/javascript">
function getSeconds() {
var now = new Date();
var time = now.getTime(); // time now in milliseconds
var midnight = new Date(now.getFullYear(),now.getMonth(),now.getDate(),0,15,0); // midnight 0000 hrs
// midnight - change time hh,mm,ss to whatever time required, e.g. 9,15,0 (0915)
var ft = midnight.getTime() + 86400000 + 43200000; // add one day 12 hours
var offset = now.getTimezoneOffset(); // local time in minutes vs GMT
offset = offset * 60000; // milliseconds
ft = ft + offset;
var diff = ft - time;
diff = parseInt(diff/1000);
if (diff > 129600) {diff = diff - 129600}
startTimer (diff);
}
var timeInSecs;
var ticker;
function startTimer(secs){
timeInSecs = parseInt(secs);
ticker = setInterval("tick()",1000);
tick(); // to start counter display right away
}
function tick() {
var secs = timeInSecs;
if (secs>0) {
timeInSecs--;
}
else {
clearInterval(ticker); // stop counting at zero
//getSeconds(); // and start again if required
}
var days = Math.floor(secs/864000);
secs %= 86400;
var hours= Math.floor(secs/3600);
secs %= 3600;
var mins = Math.floor(secs/60);
secs %= 60;
var result = + days + " days " + ((hours < 10 ) ? "0" : "" ) + hours + " hours " + ( (mins < 10) ? "0" : "" ) + mins
+ " minutes " + ( (secs < 10) ? "0" : "" ) + secs + " seconds ";
document.getElementById("countdown").innerHTML = result;
}
</script>

Random non-repeating images script. Hope this helps someone... you can see an example at http://www.empireelite.org/. Refresh and you'll see the PS3 boxarts on the top left will show randomly, with no repeats. In your html page in head tag Code: <style>
img.boxart{
margin:0;
border: none;
display:block;
float:left}</style>
<script type="text/javascript" src="ps3boxart.js"></script>
in body tag (place whereever in the body you want the pictures to show) Code: <script type="text/javascript"> randomorder(ps3ba, '') </script> In a seperate .js file in the same folder (this one I have as ps3boxart.js) Code: var ps3ba=new Array()

Then obviously, you would use this as a baseline and change your .js file name to whatever your pictures are for, like ads.js or whichever. Change the links in ahref to whereever you want each page to link. Change the image locations in img src to whereever your images are saved. Remember, where it says var z=0... this is where you hide extra random images. For example, my 200px cell only fits 9 22px wide images (they equal 198px). I only have 9 in my ps3 boxart image folder. If I want 50 in there... I would upload the pics to the folder with the other ones, add them to the list in the .js file. Such as ps3ba[9]=, ps3ba[10]=, etc. up to [49] (49 + 1 for [0] = 50). Then since I can only fit 9 in my cell, I would have to change the variable to var z=41 (to hide 41 of them and only show 9). Hope this helps somebody. Good luck. I'm using the script below in a custom HTML to generate a random line of text (not with the text shown here). This works fine BUT; I want it to go randomly through the WHOLE list without repeating lines that already have been printed. As it is now, a line of text might be printed several times in a row, which is a little annoying. I'm using a refresh button for generating a new line of text. Alternatively, How can I just make it display in the order shown and just re-arrange the content so it seems random to the user? Random would the best though... Any ideas?? : ) Code: <script language="JavaScript"> <!-- var r_text = new Array (); r_text[0] = "All the leaves are brown"; r_text[1] = "And the sky is grey"; r_text[2] = "I've been for a walk"; r_text[3] = "On a winter's day"; r_text[4] = "I'd be safe and warm"; r_text[5] = "If I was in L.A."; r_text[6] = "California dreaming, On such a winter's day"; var i = Math.floor(7*Math.random()) document.write(r_text[i]); //--> </script> Hey Guys! I've previously done HTML, but now started to learn some aspects of Javascript but getting rather confused with Loops! I've done a some coding for the Loop question (probably doesn't make sense) but I was wondering if you could help me out? I'm about as confused as a cow on a Astro Turf so my code may look terrible! - For this question you will: Draw a flow chart and write a javascript function which will use a for loop and allow the user to enter the details for four students when the program is run and display the average. Assume that they equal weighting. Hint: Javascript may assume that the value received from a prompt is a string so use parseInt() to make sure the number is an integer. Here is my code: (I'm using Aptana) Code: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">

Regards Hello, i am new here however my knowledge is not that limited like that one guy wolf who oldMaster was helping with i read the RULES and his thread lol so my question is, i have made a for loop and in side the for loop i wrote document.write(<td>date</td>"<td class = 'amt'>amount</td>); where date, amount, firstName, and lastName, are the values of the date, amount, firstName, and lastName arrays for the index indicated by the current value of the for loop counter varible so questions : i have spent the past 3 days looking online for the correct answer document.write(<td>date</td>"<td class = 'amt'>amount</td>); ?

//sets the variable to 0
var total = 0; //new Array("firstName", "lastName", "street", "city", "state", "zip", "amount", "date");
//that loops through all the values in the amount array, at each point in the loop add the current value of the array item to the value of the total variable
for(var i = 0; i < amount.length; i++)

I have the following nested for loops: Code: for (i;i<tag('entry').length;i++) {
content = content + '<tr>';
for (x;x<tag('header').length;x++) {
content = content + '<td style="width:' + tdWidth + '%; border:solid 1px #000;">' + tag('item')[x].firstChild.nodeValue; + '</td>';
}
x+=tag('header').length;
content = content + '</tr>';
}
For some reason, it seems to only loop the outer for loop once. BTW, tag() is defined, I just didn't include it. Help is appreciated. Thanks, Julian I am doing practice problems for class (not homework), and I've gotten most of the coding down except for one stipulation. The exercise reads: "Write a program that reads input of the number of hours an employee has worked and displays the employee's total and average (per day) number of hours. The company doesn't pay overtime, so cap any day at 8 hours. Sample Run: How many days? 3 Hours? 6 Hours? 12 Hours? 5 Employee's total paid hours = 19 Employee’s average paid hours = 6.3333333" I can't figure out how to include the bolded stipulation. I've tried adding: Code: if ( sum >8 ) {
sum = 8;
}
but I know that isn't right, and I can't think of any other solution. Can someone advise me on my work? Code: public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
System.out.println("How many days worked? ");
int count = keyboard.nextInt();
int i = 1;
int sum = 0;
while (i <= count) {
System.out.println("Hours? ");
sum += keyboard.nextInt();
i++;
}
System.out.println("Employee's total paid hours= " +sum);
System.out.println("Employee's average paid hours= " +(double)sum/count);
}
}
Also! If anyone can explain to me why there has to be an initialization of " int sum = 0 ", that would be great. I just know I have to include it for this loop. I created a For Loop and counter starts at 0, then increase in increments of 1 after each iteration of loop i run a command 1( add html code such as Code: <td>named (part)</td> <td class= 'num'>votes</td> Then create variable of named percent use totalV for value of sum parameter then i add html code of Code: <td class='num'>(percent%(</td> then i add a function named createBar(0 using race[0], name1, party1, and votes1 in parameter values this is my coding Code: for (var i=0; i < name.length; i++)
{
document.write("<tr>");
document.write("<td>" name[i] + "(" + party[i] + ")</td>");
document.write("<td class='num'>" + votes[i] + "</td>");
var percent=calcPercent(votes[i], totalV)
document.write("<td class='num'>(" + percent +"%)</td>");
createBar(party[i],percent)
document.write("</tr>");
}
document.write("</table>");
}

so any improvements or what i am missing in my functions. I've been asked to create a program which allows meteorologists to input a certain amount of data inputs of snowfall, and then the individual snowfall of each input itself. In my mind this should prompt me for a data input as many times as their are inputs, however, it works only for the first data input, then it returns to blank page without prompts for the second input... Any clues as to where I'm going wrong? Hey Guys, I'm currently a seasoned programmer who is in a programming class at my school. We're currently learning advanced JavaScript, and we're on the topic of nested loops. After teaching us about for and while loops, my teacher gave us a little puzzle to solve. It's kind of difficult to explain, but I'll give you guys my current code and what it outputs. Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>Word Reversal</title>
<script type="text/javascript">
var ask = prompt("How many words do you want?","");
while (ask < "1")
{
alert("You have to have at least one word!");
var ask = prompt("How many words do you want?","");
}
var num = parseInt(ask) + 1;
var final = "";
for (var i=1; i < num; i++)
{
var word = prompt("What's word " + i + "?");
final = final + "Word " + i +": " + word + "<br/>";
}
</script>
</head>
<body>
<script type="text/javascript">
document.writeln(final);
</script>
</body>
</html>
The current output, when the user wants two words, and word 1 is one and word 2 is two, comes out to be: Code: Word 1: one Word 2: two Which is great, but the only problem is, this is what the output's supposed to be: Code: Word 2: two Word 1: one I'm stumped. I've had numerous programming challenges in my life which I've solved, but I'm not sure where to go next on this one. The script is supposed to use a nested loop, but what goes in what loop to reverse the order of the user's input? I asked my teacher for help, but he told me "Ask someone else." I asked another seasoned programmer in my class, who was just about as stumped as I was, so I went back to my teacher. "Well, ask another person" he replied. And can you believe this guy has a Master's Degree of Computer Science? So I'm asking you guys: the community. I hope someone will be able to help me. On top of that, I have to help and tutor two special education students in my class on this kind of stuff during class, and they can't get the project done until I get it done, as they learn from analyzing and copying my work (which my teacher told me to do). They get upset when they have nothing to code, and they end up goofing off the entire period, or using it as a study hall. I need to get them back on track, so we can move on to the next project. Please help me with this code - it would be greatly appreciated. Thank you! Hello codingforums.com! Right, this is probably going but such a stupid newbie thread but here goes.. I've finally got myself into gear to start learning javascript. I've been watching video tutorials, learning from websites and simply learning by error. I understand the concept of for loops, but the whole nested thing doesn't seem to click for some reason. I thought i understood and managed to write a piece of code that constantly writes '*' across the screen. Could someone with some pretty damn good knowledge of javascript be able to walk me through step by step of my script to explain what actually is happening? It would help loads. here is the script, many thanks!! <script type="text/javascript"> var counter = 0; function writeStars(){ for(i=0;i<1;i++){ for(a=0;a<=counter;a++){ document.write("*"); } counter++ document.write("<br />"); } } setInterval("writeStars()", 200); </script> |
