Implementing Array And Then Calculating The Average?
Sep 16, 2011
She's wanting an array that will store points awarded and then calculate the average. It will also then show the distribution of the allocated grades (that I'm not having trouble with - just pulling the averages from the array data).
This is my code so far:

[Code]....
I've tried different ways, most ending in the 'average' variable being undefined or when the button is pressed and the function 'ReturnAverage' called it doesn't do anything. I'm using Eclipse as my IDE to work on this and check syntax.
Im trying to calculate the mean/average of numbers in an array.how can i get the length of an array to perform in a simple / maths problem whilst being flexiable to the length of the array?
I'm a newbie to javascript and I made this script <script> var num = parseInt(prompt("Enter the number of integers to follow")); var sum = 0; for (i = 0; i < num; i++){ sum += parseInt(prompt("Enter a number")); }
if (isNaN(num)) { alert("Invalid"); } else { if (sum < 0) { document.writeln("The sum is 0 and the average is 0"); } else { document.writeln("The sum is " + sum + " and the average is " + sum/num); } } </script>
The scenario : Create in javascript that will read a series of integers at the terminal. The first integer is special, as it indicates how many more integers will follow. Your javascript is to calculate the sum and average of the integers, excluding the first integer, and display these values to the screen. If the total is not greater than 0 then display "The sum is 0 and the average is 0". Did I write the script correctly? am I missing anything that a dumb person might do? for example the person might type in letters instead of numbers.
How do i use a function to find the average of the values in an array of numbers passed as argument to a function.(using java script) thank you for your help...
I am attempting a simple average calculation with javascript. I would like to have 6 boxes, 5 for the user to input a number in each, and the 6th box to display the average of the five. I have set up 2 functions to take the input, calc the total, then calculate the average. It seems to be taking the input, but on the rare occasions I get anything in the results box, it is NaN.
Here is my code: <!DOCTYPE html PUBLIC "-W3CDTD XHTML 1.0 TransitionalEN" "[URL]"> <html xmlns="[URL]"><head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <title>Calculate Average</title> <link href="style.css" rel="stylesheet" type="text/css" /> <script language="javascript" type="text/javascript"> /* <[CDATA[ */ Declare variables var calcResult Result of numbers added together and deivided by 5.
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 here:http://www.codingforums.com/showthread.php?t=4313Is 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.
for (var d=1; d<=numofinputs; d=d+1) { input = prompt("Enter a data input" + d) }
i am trying to create a interface to average down variable amount of input and show them on screen as they type....this is what i came up with.....and the input box fields....these are dynamically created...
My knowledge of programming is very limited. I would like to calculate the average of session variables in Interpreted Java. However, some of session variables may not always be available. The first thing I do is remove the non numerical portion of the session variables:
String [] variables = {"A",'B','C','D','E'}; i = 0; Iterate through each variable in the array above while (i < variables.length){ Get the variables to be fixed value = session.getVariable(variables[i]); Log the UNFIXED values session.log("UNFIXED: " + variables[i] + " = " + value); if(value != null){ Remove non-numerical elements value = value.replaceAll("\\D", ""); Set variables with new values dataRecord.put(variables[i], value); session.setVariable(variables[i], value); Log the FIXED values session.log("FIXED " + variables[i] + " = " + session.getVariable(variables[i])); } i++; }
Then I make sure the session variables can be treated as numbers: A = Integer.parseInt(session.getVariable("A")).intValue(); B = Integer.parseInt(session.getVariable("B")).intValue(); C = Integer.parseInt(session.getVariable("C")).intValue(); D = Integer.parseInt(session.getVariable("D")).intValue(); E = Integer.parseInt(session.getVariable("E")).intValue(); Are they still alive? session.log("A**" + A + "**"); session.log("B**" + B + "**"); session.log("C**" + C + "**"); session.log("D**" + D + "**"); session.log("E**" + E + "**");
I would like to calculate the average of A and B and save it as session variable AB, calculate the average of C and D and save it as session variable CD, and then the average of AB, CD, and E. Here's the weird part; AB, CD, and or E will not always be available. For example, AB will not be available so I need to calculate the average of CD and E or E will not be available so I need to calculate the average of AB and CD. As I said, my knowledge of programming is very limited so if you could provide code snippet with explanation of each step and where to plug in my session variables.
My task was to build a simple GPA calculator using select input and Javascript to average it all together and return it to the user with his name. So I started with my form which looks like this
Now to the best of my knowledge that looks correct, I made sure to use integers as the values so I could average them using this function <script type="text/javascript"> <!-- function Average(v1,v2,v3){ return Average (v1+v2+v3) / 3; } --> </script>
I need to find the average number in javascript. It is the only bit of javascript that I have to do in the course but it carries a high mark of which I cannot afford to lose. Any way the question is : "Write code to calculate the average height and write it out in the browser window"
<HEAD><TITLE> average</TITLE> <SCRIPT LANGUAGE = "JavaScript"> //Experimental results of Table 1 stored in arrays. var Height = [15,16,17,18,19]; var Number = [2,1,6,4,2];
//Part (ii). //Write code to declare and initialise new array to represent the third row of the table. var avg = new Array(5) var avg = ["60","80","187","180","114"] ; avg[0] = "60"; avg[1] = "80"; avg[2] = "187"; avg[3] = "180"; avg[4] = "114"; //Part (iv). //Write code to calculate the average height and write it out in the browser window. avg = 0; for (var count = 1; count <= 5; count = count + 1) Array.average = function(){ var avg = 0; for(var a = 0; a < this.length; a++){ avg += this[a]; } return avg / this.length; };
document.write('average height is ' +avg + '<br>'); </SCRIPT></HEAD><BODY> </BODY></HTML>
ich got a textarea and want to add a special symbol to it like average. would be awesome if there were a button next to the textfield where a dialog pops up. via click on the specific symbol it should be added at the promt in the textarea box. maybe something like that smiley input in this wysiwyg-editor. should be as easy for the user as possible.does anybody know a plugin for that problem? i googled a lot and didn't find anything suitabl
and show the rest of the content, for example it will say "More Info" when the user clicks it will toogle down and reveal the rest of the content which for example sake can be "Heres more info".
I've just had a look at your fading opacity script. As I'm new to programming and I'm amazed by the script could I ask for some hints how to implement it in a site with a mouseover, mouseout events?
[URL] however i want to impliment this into my form. if false I want it to return an alert saying postcode not valid and then stop the form submitting, else i want it to just allow the form to submit.
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 would like to know if anyone has some javascript code that reads an external, arbitrary, XML feed, and can display the 2 or 3 latest submissions based on the XML src.
Is such a task even possible with just client-side javascript?
I need to implement a next to last selector for our project. I came up with the following code: jQuery.expr[':'].next_to_last = function(obj, index, m){ var $this = jQuery(obj); return $this.find(m[3]).last().prev(); }; Is there any problem with this implementation?
Im having trouble implementing a countdown clock from within a php page. I am using the countdown clock from dynamic drive. It works well if I have the javascript in the php page, but when I move it to an external js file clock.js it gives an 'invalid date'. Does it have something to do with the php tags inside the function ? below is the code.
I'm making a project which creates tabs with a class. I don't really know how to explain it better but this is how it works:
<a href="#" id="tbs_tabs">Create</a> <script type="text/javascript"> var tbs = new Tabs('tbs_tabs'); tbs.theme = 'classic' tbs.create_option('abc','#'); tbs.create_option('abz','#'); tbs.create_option('abf','#'); tbs.create(); </script>
It first creates the new class and tells it the id, then it creates as many options as you want and creates it.
My problem is with this line: for(i=0;i<this.option_values.length;i++) { li = document.createElement("LI"); li.appendChild(document.createTextNode(this.option_values[i])); addEvent(li,"click",function(){oThis.select_option(i); return false;};
ul.appendChild(li); }
What I was trying to do here is add an event to the LI element that refers to the current tab class but doesn't use the CURRENT i value but the value that was when the event was first created.
For example.. If my i value is currently 2 and I add the function, then I want that when I call the function, the value will still be 2 and not the current i value. What happens now is when I call the function the value is something like 5 or 6.
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?

It could be a two function javascript or two separate javascripts, I am not that particular as long as it does what I need it to do. The way I would like to see it work is you type the number you have into a field, and press a button to convert it. If it was a two function javascript you would have to select the conversion type you want do first.
I have a grid of items that when clicked lead to a new page. I would like to implement a function so that if a user clicks on an item and holds for at least 1000ms, a menu will be shown next to the item and they will not be taken to the next page.
However, all of my current attempts either lead to the menu not being shown, or it is shown and the user is redirected to the next page anyways.
Here's my current code:
jQuery(document).ready(function(){ var mousehold; jQuery('.item').mousedown(function(){
