JavaScript - Request: Simple Counter (average)
Hi,
First i don know if im posting at the right place or if you even take request here, feel free to direct me to the right place. What i am looking for is someone to make a simple counter for me. Basically i want that every time i press a certain key on my keyboard it will increase the counter amount and would then divide it by 60 every hour. Actually im looking for it to only show that average and refresh every hour. So it would start at 0 then update after the first hour and so on. (I also need a graphical interface) I have very few knowledge in coding and would very appreciate if someone could do that for me. Thank you !

Join Date Feb 2009 Posts 28,311 Thanks 82 Thanked 4,754 Times in 4,716 Posts I don't think this is something you would do with JavaScript. I think you need a ".exe" (on Windows) program. And that's a lot more complex. The problem is your request to capture a certain key, presumably no matter what window is at the front. Normally, within a given window, you can only capture a key that is intended for that window. I don't think this is a very easy thing to do. Similar Tutorialshi, I had a doubt... here is a simple ajax program to return the length of the string entered in the input html: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<form action="fallbackpage.php" method="post">
<p>Welcome, student. Please enter your essay he </p>
<p>
<textarea name="essay" id="essay">

</p>
<p>
<input type="submit" name="submit" value="Submit" onclick="
grade(this.form.essay.value);" />
</p>
</form>
</body>
</html>
Java script Code: // JavaScript Document
function grade(essay) {
// Mozilla version
if (window.XMLHttpRequest) {
xhr = new XMLHttpRequest();
}
// IE version
else if (window.ActiveXObject) {
xhr = new ActiveXObject("Microsoft.XMLHTTP");
}
essay=encodeURIComponent(essay);
xhr.open("POST","grade.php");
xhr.setRequestHeader(
'Content-Type',
'application/x-www-form-urlencoded; charset=UTF-8');
xhr.send(essay);
xhr.onreadystatechange=function() {
if (xhr.readyState==4) {
grade = xhr.responseText;
alert(grade);
}
}
}
php: PHP Code: <?php function grade_essay($essay) { return strlen($essay); } $essay = urldecode(implode(file('php://input'))); $grade = grade_essay($essay); echo $grade; ?> I just use an alert box to alert the length. The script works properly ONLY when the AJAX request is able to outrace the submit request.... which doesnt happen. I have included the action="" part as a fallback option incase JS is disabled What am i doing wrong here? I am learning JS now in the free time... Also i did notice this... when i change the submit button in html to the following code i get 2 alert box..1st one's undefined(i know why) but second one's i will get proper answer Quote: <input type="submit" name="submit" value="Submit" onclick="alert(grade(this.form.essay.value));" /> PS: This is a tutorial here http://www.webmonkey.com/2010/02/aja...ners/#more-775 So I am making a function that takes numbers and when you enter a letter than it's supposed to skip to the if statement and give the average. The problem is that it doesn't seem to add the number to total on each loop. the first code is what I am working with. I was supposed to take a While loop and turn it into a do-while loop. The second peice of code is the original while loop. } Code: var finding_average = function() {
var total = 0, count = 0, number;
alert("Enter the numbers to average. Enter any non-number to stop.");
do {
number = parseInt( prompt("Enter a number") );
total = total + number;
count++;
} while ( !isNaN(number) );
var average = total / count;
if ( isNaN(average) ) {
alert("You didn't enter any numbers.");
} else {
alert("The average is: " + average);
}
Code: var finding_average = function() {
var total = 0, count = 0, number;
alert("Enter the numbers to average. Enter any non-number to stop.");
number = parseFloat( prompt("Enter a number") );
while ( !isNaN(number) ) {
total += number;
count++;
number = parseFloat( prompt("Enter another number") );
}
var average = total / count;
if ( isNaN(average) ) {
alert("You didn't enter any numbers.");
} else {
alert("The average is: " + average);
}
}
hi I need to find the average number in javascript. I have been working on it for a while but i am getting no where yes i am new to javascript and to be honest it is doing my blonde headed brain in. can someone please take a look at it and advise me on what i am doing wrong. it is the only bit of javascript that i have to do in the course but it carries a high mark of which i can not afford to lose Any way the question is : "Write code to calculate the average height and write it out in the browser window" Code: <HEAD>
<TITLE>

var avg = new Array(5)
var avg = ["60","80","187","180","114"] ;

sorry for my ignorance thanks in advance kelly XXXXX helow to every one im new here....i hope im welcome here can i ask how to make this problem? input 20 number and print the average of the numbers....any one can help me please... Hello, I'm new here and a newbie to the world of java script. I am taking a CIT class and we just moved on to java script which i am having trouble with. My assignment is to calculate the average, number of passed, and number of failed grades according to this list (65, 80, 85, 55, 90, 70, 62, -1) where it terminates at -1 and the passing grade is >=70. Any help is appreciated! Hi i need to find the highest average from all of the averages entered in this code, but i have to use an if statement only, no arrays. Could some one help please? Code: // ** Work out average ** //
average= readingSum/totalReadings
// ** Put average into a category and display everything ** //
if(average<5)
{
catergory1=alert("Location is " + region + "\nNumber of weekly readings taken is " + totalReadings + "\nTotal of readings is" + readingSum + "\nAverage is" + average + "\nLocation is Dry");
}
else if(average>=5 && average<20)
{
catergory2=alert("Location is " + region + "\nNumber of weekly readings taken is " + totalReadings + "\nTotal of readings is" + readingSum + "\nAverage is" + average + "\nLocation is Normal");
}
else if(average>20)
{
catergory3=alert("Location is " + region + "\nNumber of weekly readings taken is " + totalReadings + "\nTotal of readings is" + readingSum + "\nAverage is" + average + "\nLocation is Wet");
}
// ** Find Highest average ** //
Thanks. I need to allow a user to enter 3 values, then display the average between them... I am having some real issues with the average, Thanks! var quiz1 = prompt("What is the score of your first quiz?", "") document.write("Return Value: "+quiz1, '%',("<br />")); var quiz2 = prompt("What is the score of your second quiz?", "") document.write("Return Value: "+quiz2, '%',("<br />")); var quiz3 = prompt("What is the score of your third quiz?", "") document.write("Return Value: "+quiz3,'%',("<br />")); average= ("quiz1"+"quiz2"+"quiz3") /3 document.write(average,("<br />")); I've now got to form an average of snowfall inputs, taken from looped prompts, however I'm not allowed to use arrays or functions... Almost every example I see uses arrays, such as this one he http://www.codingforums.com/showthread.php?t=4313 Is it possible to not use arrays to form the average? Please describe how to do this in general terms, as was highlighted in that link ^^^ I want to learn, not copy, although one can be derived from the other... What I haveso far, assume all vars have been announced. Code: for (var d=1; d<=numofinputs; d=d+1)
{
input = prompt("Enter a data input" + d)
}
Is it possible I'm attempting this in too general a manner? ie, running before I can walk. Hi all, I am in a non-major class called webprogramming working with javascript and I'm having an issue with a specific code wondering if someone could tell me what's wrong! So I am suppose to compute and return the average of all values in a given array named customerBalance, the array holds the amount of "what customers owe my business" (I dont own a business) and each item in the array holds the "customers balance", i also have to use a for() to process the array and calculate the average and divide by customerBalance length, and finally return the average. Here is my code so far <script> function average() { customerBalance for(i=0,i++) sum(customerBalance) total=sum/5 return average; }; </script> I know that this is COMPLETELY wrong, I am not sure on how i start typing the array, please don't be harsh I would really like to know how to do this. Thank you and have a great day I've written a program which will prompt for a number of cities, Prompt for the name of the city, then prompt for the number of snowfall readings of that city, and then prompt for each of these individual snowfall readings of that city. From this, it adds up each of the individual snowfall readings of that city, and will calculate an average by dividing this figure [the total snowfall] by the total number of readings for that city. This average is used to then classify the city as "not snowy", "mild", or "blizzard". I'm happy to PM my code to anyone willing to help out, as I realise this is a complex structure to visualise perhaps, but I can't post it publicly. I now have to select the city with the highest average, and name it in an alert output. How is this possible. Note, I'm not allowed to use functions or arrays. Prompts, alerts, if-then-else, for and while loops are all I can use. I've been messing with this code for about a couple of hours, and I did everything down to the wire..yet still I am unable to get it to work. When I input the numbers, and click off to the side nothing appears down at the final textarea of the form which is suppose to show the average. I've tried just about everything, sadly all I have to go by is other example codes, and the very intricate instructions which states I must pass the values to the calcAvg() to the second function of performCalc(), which I did, and then I assigned the var calcResult another value. From there I did the return..and after that I'm rather loss as to what to do next to get this code to work, any tips? Code:

So I'm really new to javascript and html. The most advanced thing Ive made was probably a Russian rullete simulator, but I need help with this one program Im working on. So if anyone could tell me whats wrong with this, I would appreciate it! <html> <head> <font size="4">Click the button below as many times as you can</font> <br> <script type="text/javascript"> var clicks=0 function count() { clicks=clicks+1; } </script> </head> <body> <input type="button" value="Click Me" OnClick="count()"> <br> <p>Clicks: <script type="text/javascript"> document.write(clicks); </script></p> </body> </html> Hey Everyone, I'm working on a counter. I have two images - each with their own click count. Right now each time the page loads the counter goes back to zero. I would assume I need some kind of server side coding. Any recommendations? Here's what I have so far. <html> <head> <script type="text/javascript"> var counter = 0; function increaseloveit() { counter += 1; document.getElementById('loveit').value = counter; } var counter = 0; function increasehateit() { counter += 1; document.getElementById('hateit').value = counter; } </script> </head> <body> <form> <a href="#" onclick="javascript:increaseloveit();"><input type="button" value="Love It!" name="loveit" onclick="" /></a><input id="loveit" value="0" size="2" /></form> <form> <a href="#" onclick="javascript:increasehateit();"><input type="button" value="Hate It!" name="hateit" onclick="" /></a><input id="hateit" value="0" size="2" /></form> </body> </html> I am trying to use the Jquery loader (this ends when page loads) but I want it to load how many seconds the page took. (using the clean preloader) $( "#progressbar" ).progressbar({ value: setTimeout("seconds++",10000000) }); but getting "anything" to work in the "VALUE" has been such a pain. any one that knows how to create a timer to add to the value so that preload will keep loading? or if even possible? thanks I have the following codes and it seems to work well but when exiting the site and re-entering it resets the values to 0 again. I am not sure how to proceed with this, been considering cookies but what if the user clears there cookies, I then looked at PHP but not understanding that to well at this stage. Javascript Code: // Function to count clicks on links
var clicks1 = 0;
var clicks2 = 0;
var clicks3 = 0;
var clicks4 = 0;
function link1(){
document.getElementById('clicked1').value = ++clicks1;
}
function link2(){
document.getElementById('clicked2').value = ++clicks2;
}
function link3(){
document.getElementById('clicked3').value = ++clicks3;
}
function link4(){
document.getElementById('clicked4').value = ++clicks4;
}

Please Help? Hi All, could you please help me. A have a little program and i need to count somehow how many times a while loop is ran. how could i do that? Thanks for your help I need help with a counter that will either display a different image everyweek or change text every week. The scenario is a counter will be on the top right corner of the page, and every week the number will change from 1 to 2 to 3... to 52... I searched on this forum for answers, i found some similar for a different day counter. Any help would be great! H, I'm trying to create an sms form. but I want the users to be able to monitor the characters and sms number as they type...taking 160 characters to be 1 page. pls I'll need help with coding this form to display characters left in 'ch_count' box and number of pages in the 'pages' box while typing in the 'message' textarea....hope it's clear enough...thanks Code: <p> <textarea name="message" cols="" rows="" id="message"></textarea> </p> <p> <input name="ch_count" type="text" id="ch_count" size="8" /> characters left <input name="pages" type="text" id="pages" size="8" /> pages </p> Hi, I have added a time counter in below code. This is used to track the total time of a project. If a person is going on break, then they will apply the break that stops the time counter. However, once they come back from break and end the break, then time is counting at double speed (two seconds instead at one second). Is there any mistake that I done that made the time counter to increment by 2 seconds instead of 1 second after break. Any help please.... Code:
