How To Find / Calculate Average Number

Feb 1, 2010

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>');

JQuery :: Calculate Number Of Months Between Date Ranges?

Aug 3, 2010

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.

Script For Counting A Number - Want Down To Another Number That Resets?

Nov 28, 2011

I am trying to figure out how to make a random number I can plug into a script count down from that number at certain times of the day until it reaches 0. I would like it to reset itself at midnight every day. I'm trying to make it work with a script I found on here that resets itself at midnight every day. So instead of it counting down too fast, it would count down to the next number after a randomly generated number of minutes until it reaches 0. But it wouldn't necessarily have to end at 0 at midnight. It could go from 845 to 323 at the end of the day at a slower pace. Is that possible?

JQuery :: Replacing Number In Url With Another Number?

Oct 13, 2011

What i'm trying to do is replacing the size=180 part of the src (in this case an image) with size=400 so that the images appear larger. I can't simply replace any "180" with "800" because the value might be present in the lid or isbn.So far I've pretty much cut the url up in pieces (I reckon it could be done a lot easier), but I'm stuck with replacing it.[code]

Regular Expressions Replace - Detect The Number "2" And Put It Superscripted Past The Number 5

Jan 3, 2011

Formerly I've been replacing characters with javascript using the following code.

paramString = paramString.split("").join("<sup>");
paramString = paramString.split("").join("</sup>");

So if the user on my website types 52 it would return the following value: 5<sup>2</sup>, or just, 5 how do I detect something like this. if they enter: 5 how can I detect the number "2" and put it superscripted past the number 5. so the javascript reads this: 5 and returns this: 5<sup>2</sup>

Calculate While I Type

Jun 29, 2006

I believe that this has been answered somewhere but I cannot find it. I have 51 textboxes on page. In 50 I can enter value. 51st should tell me what is average of entered numbers.

As user types I want script to iterate trough form count and sum non-empty fields and than divides this two numbers.I need to sum values from fields that have value (not emty fields) and to divide this number by number of non empty fields. This should occur on every change in any of those 50 textboxes so to have live preview of average.

I'm really new to JS and I don't know even how to sum these numbers.
