How To Find / Calculate Average Number
Feb 1, 2010I 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>');

GPA Calculator - Using Select Input And Average It
Oct 7, 2011My 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
<tr><td>
<form name="GPA"
<p> Test 1</p>
</td><td>
<select id="v1">
<option value="4">A</option>
<option value="3">B</option>
<option value="2">C</option>
<option value="1">D</option>
<option value="0">F</option>
</select>
</td></tr><tr><td>
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;
}
-->

Use Variable Instead Of Number For Function Input?
Oct 29, 2009I'm using simpleCart() javascript shopping machine for my page.The script accepts values in a specific syntax:onclick="simpleCart.add('name=Some name','price=23.4','quantity=1');"But because the price of the product is not always the same but comes up after previously made calculations, i want to parse the values in simpleCart() through another function. I have made the following one which gets the price from a textbox (resultAlmires) of a form (Almires), then converts it to american format (. instead of ,) makes it have one decimal only and finally parse it to simpleCart() with the use of a variable.However it doesn't seem to work:
function addAlmiri() {
var timi = document.Almires.resultAlmires.value;
timi = timi.replace(/,/,".");

Unlimited Number Of Additional Input Boxes?
Jun 21, 2010I have to input an undefined number of rows of data. Existing data is read from a database. There is an Add button after the last row.
I can see how to add the next row: there is a hidden blank row with visibility set to 'none', which is turned to 'block' by clicking the Add button.
How can I continue to add rows? Do I need to have a large number of invisible rows and turn each one on as required? (I don't want to have to submit the form for each row, which would be another solution).
How To Prevent Mozilla Using A Link If A Wrong Number Is In An Input Box
Feb 1, 2006In my example the focus should only jump to textbox2 if you press the tab
key and if ཇ' is in textbox1. That works fine.
However if you enter e.g. ཈' in textbox1 and click on 'Link', Mozilla
shows the alert 'Wrong numer' but also jumps to 'www.google.com'.
Opera and IE don't do that what's in my opinion the correct behavior. Code:

Adding Multiple Input Boxes And Getting A Total Different Number Every Time?
May 19, 2011ave this form which gets created by pulling stock/products from a database using PHP and beside every product in the row is a little box for input and in there the user can input the quantity of the product they want. Sometimes only 2 products will be outputted and other times 10 or more.What I want to happen is when the user enters in lets say 3 for the quantity of a certain product I want to get a total for how much 3 of that product will cost so I just do 3 multiply by the cost (which I have from the database) and then display the total cost down under where the list of the available products are and I want all this to happen dynamically obviously not using PHP because I don't want the page to have to reload every time they enter in a new quantity.
I know how to display text and stuff in certain divs with certain ID's using Javascript but I just don't know how to keep track of a form and do what I want to do when the number of inputs in the form can range from 1 to 10 or more. Im thinking of some sort of counter which gives every input a different ID like add 1 at the end of the ID name of the input as the PHP script loops through the database query displaying the products but I still don't know how to go about the Javascript side of things
Creating A Form That Will Change The Number Of Fields Based On User Input
Jan 4, 2006I have a form that collects information about up to 5 items. I would
like the user to be able to select from a drop down menu how many items
for which they want to compare information, and then have the form
change the number of input fields accordingly.
In other words, if the user selects enter info for 3 items, then input
fields for only 3 items are shown, if they change it to 4 items, then a
fourth column shows up in the table with the appropriate input fields.

Display Average Of Five Into Sixth Box?
Apr 7, 2011I 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.

Alternative For Document.write - Calculator That Takes Number Of Songs From Input Text Box
Jan 16, 2011I have a simple calculator here that takes the number of songs from the input text box and multiplies it by 500 and then tells you the total. I am doing this on a simple web page for a project for college. I know document.write overwrites my entire page to print the result but I would like to keep the page and design that I have made and to print the result on the same paragraph as where the script and text box are.

Calculating Sum And Average Of Integers And Display Value
May 25, 2009I'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.
