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>');

I am having some difficulty in constructing a window.confirm() function that works with my code.So if the form data is valid, I need to use a window.confirm() dialog box to show the user's total cost based on the rental rate of equipment chosen and the reservation period. The user must accept the cost by pressing the confirm button, and if user cancels do not submit data.I have written this code but cannot figure out how to find the number of days from the 2 date fields and use that to calculate and display the total cost.

//confirm submit and display rental cost var equip = document.forms[0].equipment.value var pDate = document.forms[0].pickupDate.value[code].....

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.

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?

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 want to calculate the percentage of a number, but I'm getting a really weird result. In the following code f is equal to 3 and x.length is equal to 8. The part that isn't working is emphasised in bold. Basically 3/8 * 100 should result in 37.5 but the result I am getting with the following code is 7934570.3125. How do you calculate this percentage in Javascript?

I have a form that posts a Date In and a Date Out to another form. The variables are datein and dateout in format mm/dd/yyyy Trying to use this function to calculate number of nights :

Code: <SCRIPT LANGUAGE=javascript> <!-- function DateDifference() { date1= Date.parse(form.datein.value)

I am new to Java scripts. But at my job, my boss asks me to come up with a calculator that calculates the number of weeks on our website. But I want two calenders where in the first one the user will select the start date and in the second one, the user will select the end date. And There will be one last button that says"calculate" and a text box to display the number of weeks.

I have many inputs with name totalsum1,totalsum2,totalsum3 etc. I need to calculate number of inputs where name starts with "totalsum" and value is >0. I need to send result to another input with id="#rowtotal".My code:

$("#rowtotal").val(($("input[name^=totalsum]").val>0).size()); It's not working. Best RegardsRafa‚ Koszyk

For a project that would be too hard to explain, I am working with date ranges. There is a begin date and an end date. With those two variables, I need a function to calculate the number of months between both dates. To be more precise, I need a count of all unique month names in the dates (or month numbers if that is easier) where the range includes the beginning date, the end date, and all dates in between. So I am not looking for full months or an approximation. If only, say, one day of a given month is included in the date range, that adds a month. Also the range can span several years, january 2010 and january 2011 need to count for two different months.

I have a program in which a user must enter number of books and price and then calculate the total cost of the items, i have tried and tried to get it working to no effect can anyone see where i have went wrong.

I am working on my assignment: The assignment is: The process of finding the largest value (i.e., the maximum of a group of values) is used frequently computer applications. Write a Javascript program that input a series of 10 single digit numbers as characters, determines the largest of the number and output XHTML text that displays the largest number. Your program should use 3 variables as follows:

a.) COUNTER: A counter to count to 10 (i.e. to keep track of how many number have been input and to determine when all 10 number have been processed). b.) NUMBER: The current digit input to the program.

There will be from 1 to 4 Pts, if one is missing there will not be a next one. My problem is I replace the first occurrence of any number I find and for certain factors (2 in this case) it could change an already converted number and leave other fields in the record alone. I could split the line on commas to change the first number I find but can't be certain if there are no other commas elsewhere on the line.

Is there an efficient way (ie. not looping through all members and counting) to find out what number an li will get in an ordered list? For example: [code]...

Naturally #first and #second will be 1 and 2, respectively. Without looping though all children of ol and counting, can I determine the number for #first and #second?

Basically I want to factor a number and select the two closest numbers to the middle of the factors for example: 20 factors to 1, 2, 4, 5, 10, 20 I want it to return 4 and 5 If the number is has an odd number of factors (has to be a perfect square) I want it to select the middle number and say it twice for example:

64 factors to 1, 2, 4, 8, 16, 32, 64

I want it to return 8 and 8 Would I use an array or what? My code should probably look like:

After retrieving a record from the database and displaying one of its text field in an input-type textbox, I click on a word and it'll store or show the current position of cursor in a variable. I have no success with IE's caretPos.

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.

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?
