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...
<input type="text" name="datup[0][4]" size="3" onchange="calc()" >
<input type="text" name="datup[1][4]" size="3" onchange="calc()" >
<input type="text" name="datup[2][4]" size="3" onchange="calc()" >

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 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'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?

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 am in the middle of designing a website and I am pretty new at it. The guy I am designing the website for wants me to make input fields that calculate data that is entered into them. There are 3 formulas that I need to make.
a=b*.262*c
c=a/(b*.262)
b=a/(c*.262)
They are the same formula just solving for different variables.
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:

I am trying to code a webpage that does the following:Listens for user key presses in an input box and dynamically writes them below the input box in a textarea.
View 5 Replies View RelatedI'd like some help trying to generate input fields on the fly. What I
have on an HTML page is a single text input field labelled #1, e.g. #1
<input type="text">. Next to the field is a button that, on click, I'd
like to automatically generate a second text input field below the
first, labelled #2. Everytime the button is clicked, another field is
created with an incremented label.
I explored iframes, but these text fields will be part of a larger
form that has to be passed together. I'd rather not use hidden text
fields because I don't want to hardcode a limit to the number of
fields available. Please point me in the right direction, or let me
know if this isn't possible.
I'm adding dynamically created input type='file' controls via JavaScript.
However when I try to access they do not seem to be returned in the form

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.

I'm attempting to submit a form via a function which dynamically creates a
hidden input:
function submitLocation(theForm) {
var e = document.createElement('input');
e.setAttribute('type', 'hidden');
e.setAttribute('name', 'location');
e.setAttribute('value', Ƈ');
var f = document.getElementById(theForm);
f.appendChild(e);
document.forms[theForm].submit();
}
The function is called from an anchor's onclick event:
<form name='form1' method='post' action='action.php'>
<a onclick="submitLocation('form1');">Submit</a>
</form>
However the function produces an input which is missing the name element:
<INPUT type=hidden value=1>
The desired output should be:
<INPUT type=hidden name=location value=1>
I'm adding an input and select box to a div by setting the div's html. I then attach a change event to the select which posts to a php page using ajax. I'm having a problem however accessing the value of the input from the change event. This is the event.

I am having a form with a drop down and want to display the fields below it based on the drop down value selected.
for example: my form has a drop down <select value> <values: A, B ,C, D)
when I select A then I should get displayed a set of fields ( like input fields, drop down fields etc) just below the main drop down and when I choose B then it should display a set of fields specific to B and like that..
