I am trying to figure out a way to modify all elements in an existing array by adding a value to the value already in the array.
I need to prompt the user to input a value and add that value to an index in the array. I was thinking of using a for loop as I need to do the same for each index in the array.
I am trying to add the elements in an array together and display the result, I am using a user prompt to obtain the elements for the array, this works fine but when I come to add the elements together and display the result all I get is a row of the elements not their sum. The user inputs are all integers (the program adds the prices of items together so they are all numbers,amounts). If the user enters 10, 15,15,20 the result I get is 10151520 not 60.

I want to create an associative array dynamically pulling the index values from an array (propertyArray); Associative array is created inside create function and then returned. But after it is returned, I cant use index names to retrieve values. It returns undefined as below code shows.
Code JavaScript:
var propertyArray=["a","b","c"];
function create(){
var array=[];
[code]....
function read()
{
var numbers = new Array();
for (i = 0; i < field.length; i++)
numbers[i] = document.test.checkboxName.value;
var counter=0;

I want to read the values of the checkboxs and store the vlaues into an array (there are more than 1 checkboxs) the form name is text and the names of the check box = checkboxname
This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code:
var flag;
for (i=0;i<=pdfs.length-1;i++)
{
flag = 1;
for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.
I have the following array:
I would like to add up the common values so add all values of Android into one array so it becomes something like this: [["Android", 92]....]
I have following function, but how can I do addition?
if
f.Field1.value =2
f.Field3.value =3
f.Field4.value =1
then
f.Total.value =231, instead of 6
function update( ) {
var f = document.myform
f.Total.value = f.Field1.value + f.Field2.value + f.Field3.value
return true;
}
var purchasePrice = window.prompt("Please enter the purchase price:", 0);
function calculateTotalCost () {
if (purchasePrice <= 25) {

I am still getting the same error, concatenation instead of addition, i can't figure out why. (i.e input 50, result 505 instead of 55.):
Talking about a js script which changes an iframe src through a "ref_to
iframe.setAttribute("src", document_path);", I would like to launch a
check() fct when this new document is loaded.
Of course, knowing, I don't want (and can't n some cases where document
is generated by a cgi script) to edit every possible document which is
potentially loadable in the iframe.
In fact, I've through about the idea to on fly add an "onload='check
()'" to every document, but don't know how to do that :-(
Maybe using attachEvent or something arounnd this : I don't know. Of
course, I wish a solution working in the majors browsers.
i have this simple function...
function update(value, oldvalue)
{
var a = value;
var b = oldvalue;
var result = a + b;
document.form.fieldname.value=result;
}
and call the function using a field with this...
onkeyup="update(this.value, other)"
But all its doing is concatenating the 2 numbers together as though they are strings!!!
so if this.value = 11
and other = 15
it displays 1115
i want to add them and display the total, do i need to specify them as being integers or something?
I am having trouble making a website for a vacation rental I pieced this javascript code and form together with a simple goal in mind: -to have 3 checkboxes each with its unique variable
weeks: 2,000
weekends: 325
weekdays: 275
-to allow users to check one or more of the checkboxes, and multiply it by a quantity they choose (ie "I'd like to stay for two weeks (2 x 2,000=6,000) and one weekday (1 x 275=275)
-finally, to add up the totals at the end (6,000 + 275=6,275)

I need to pass an array of client side events to the next page. Here my user would perform a few events which would be stored in a javascript array, upon completion a submit button would be used to post all that data to the next page.
An example of such a process is listed below, returning that array back to php so that I can post it to the next page. I am trying to populate different entries made into textbox into the array arr. And when I would click the submit button, I want to post that array.
<html>
<head>
<script type='text/javascript'>
function retText(form)
[Code]....
I want to return that arr back and on post I want to send that array to the next page.
I have an array similar to this:
Code:
0 -> 0
1 -> 5
2 -> 9
3 -> 2
[Code].....
There is no clear logic and that does not matter. I need to decrease the values of those by one where the value is higher than x. How would I do this?
For instance, if x = 5, then that array becomes
Code:
0 -> 0
1 -> 5
2 -> 8
[Code]....
All values higher than 5 were decreased by one.
var IdContainer = new Array(); for(i=0; i < SEARCHNO; ++i) { var search_ID = xmlDoc.getElementsByTagName("searchID")[i]; var SEARCHID = search_ID.firstChild.nodeValue; if(SEARCHID !== IDCONTAINER) { code to add the SEARCHID to the IDCONTAINER array here
Now what i want it to do is every time the for loop runs the if statement checks whether the SEARCHID variable is not equal to the values in the IDCONTAINER array....if this is the case then the code after the if is run and the value in the SEARCHID variable is added to the IDCONTAINER array.
Problem is i dont know how to structure the if statement to check all the values in the array against the SEARCHID and then i dont know how to update the array afetr the if with the new SEARCHID.
I have this software that returns an array like this:

[18,25,30,25]
Let's say i have two arrays:
var array1 = ["1","2","3"];
var finalArray = [];
and I want to dump the values of array1 into finalArray several times to end up with the value of finalArray being:

What would be the easiest way to dump the values into the other without making it multidimensional?
Can a javascript array value be used in an onclick event?
I haven't been successful in getting it to work so I'm wondering if it
even can be done.
onclick="calculate('some array value');
I've tried:
onclick="calculate('<script
type="text/javascript">document.write(points[0]);</script>');
There's conflict with the quotes, but beyond that, I'm unclear if this
is even a viable option...anyone?
