I'm trying to add together some values held in an array to give a total score. But no matter what I do I get "NaN" instead of the answer. I thought that bunging a couple of parseFloats in there would fix it, but that hasn't worked either.

I was originally under the impression that css style properties could
be accessed/ listed since they exsisted as an array somewhere.
Is this just flat out wrong?
To illustrate - I guess I thought something like this could be used to
list available/ or set properties, or in this example the first
property. Is this just a fantasy? Or how does this work, at this level
or for document objects even?
//assuming <div id="menu"></div> exisists and hs styles applied....
document.write(document.getElementById('menu').sty le[0]);
//of course this is wrong...
I have 8 peices of data in an Array and I need to add the final 6 to give me a total, but the results are not what I expected. Array example - Code:
var Networking_2009_1 = ['Justin Hopkins','JBH','1','2','3','4','5','6'];
I am adding the values like this -
Code:
var feeEarnerTotal = 0;
for(t in Networking_2009_1)
{ if(t > 1) // 0 and 1 are the Long Name and Short Name, so must be skipped
{ feeEarnerTotal = feeEarnerTotal + Networking_2009_1[t]; }
}
The problem is that when the value is output to the screen it is '123456' rather that '21' as expected. I suspect this is because there is writte data also in the Array, but I'm not sure how to fix it.
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=[];

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 am getting some numeric values entered by users in textbox and need to sum them up. I am getting the values fine from text box but when I do: var total = baseprice + metal + colour; Then instead of summing them up it shows me: 1002030 where as it should be: 150

View 3 Replies View RelatedI'm currently designing a website for a takeaway company, and have one page displaying their menu. So that customers can easily calculate how much their takeaway will cost, I'm going to put checkboxes next to each item.Each of the checkboxes' value will be the price of the item, and I need a script that will add the values (prices) of the checkboxes they've ticked.They can then see the total cost of their takeaway without having to work it out, and add or remove items accordingly. I will then add a button which will print out a list of the items they ticked with the total price at the bottom. The customer can bring this in with them and the staff can easily see what they want and how much to charge them.
Firstly, I need to know how to make Javascript add these values (and probably save them as a variable) Secondly, how would I make this display on the page (either after they click a button, or automatically so they can see the price real-time)? - I assume this would be basic coding --- document.write(var) And finally, how could I make a script which would print only the items which are ticked, and the total price?
I have a numerical value (lets say £11.60 for example) that is passed to another page (ie booking.html?price=£11.60). What I want is for that value to have a certain number added to it. The code below is what I have tried to do this, but I only get the value with the numbers added to the end of it (ie £11.605 instead of £11.65). I need the .replace to stay there as it filters out the random characters that appear because of "spaces" that are passed along with the other variables. Ive tried parseint() and parsefloat() but always get NaN as a result.

Is there a way to detect a held-down button while the mouse is moving?

View 3 Replies View RelatedI have a large form, that has text boxes of numbers in rows and
columns. I need to sum the values in the columns, and put the total at
the bottom of the column. But I also need to sum the values in each
row, and put the total at the end of the row.
What is the javascript to sum the values to a few text boxes, and how
would I write the script for these totals to run all at once?
I type something on the current textarea/input and all the values get removed after I add another field.
<script language="Javascript" type="text/javascript">

//Add more fields dynamically.
function addField(area,field,limit) {
if(!document.getElementById) return; //Prevent older browsers from getting any further.
var field_area = document.getElementById(area);
var all_inputs = field_area.getElementsByTagName("input"); //Get all the input fields in the given area.
//Find the count of the last element of the list. It will be in the format '<field><number>'.
If the
//field given in the argument is 'friend_' the last id will be 'friend_4'.
var last_item = all_inputs.length - 1;
var last = all_inputs[last_item].id;
var count = Number(last.split("_")[1]) + 1;
//If the maximum number of elements have been reached, exit the function.
//If the given limit is lower than 0, infinite number of fields can be created.

I am trying to take the values of 2 or more select boxes, add them together and then update a text field each time a selection in one of the select boxes is made. Basically, I am trying to keep a running total.
Currently I have it set up so that onchange it grabs the selected value. The problem is that it is being processed as a string I believe. For instance, if there are two variables, a=111 and b=222, the output in the text field reads 111222. I tried using parseInt, but that just returns NaN (not a number?...just a guess).
I have seen this solved with if statements, grabbing the selected index # and then assigning an integer, but I am hoping there is an easier way.
How would I create and IF .. ELSE statement using the following check: the LMB needs to be pushed down while the mouse moves up? I assume that mouseup() and mousemove() need to be used. but putting them in an IF conditional I am not sure about... not sure how to make the check to ensure both are true.

I have several checkboxes that on .click add their ID to an xml string. I am having trouble with it adding multiple ID's, currently if you have one checked and check another, it overwrites the previous. Here's what I have:
if ($(this).is(':checked')) {
services += '<SERVICE><SERVICECD>' + this.id + '</SERVICECD></SERVICE>';
}
How do I make this work with multiple ID's so it adds/removes each one based on click, not overwriting? I need to be able to have multiple ID's added to the string.

I'm currently working on a website called 'eXtreme Gaming' I've almost completed it, apart from two things.
- Adding two values on my checkout page for the Grandtotal (I've tried everything, but I'm too much of a noob and have probably missed something small).
- Validation of forms (I don't know where to start here, I've looked on w3schools for tuts etc but I'm having difficulty incorporating it on my site)
I have some asp:radiobutton lists that need to update a label with the sum of their values each time a user selects a new value. I am brand new to javascripting and would like some insight on how to get this done. I have inserted my code below. :thumbsup:

<asp:RadioButtonList ID="rdb1_1" runat="server" RepeatDirection="Horizontal">

I want to do is add the values of seven text fields on a form and pop that value to an eighth field. I thought the code below would work, but I get "NaN" on the sum field.
Code:
function addHazWaste() {
document.getElementById('HazardousWaste').value = 0;
var HazWasteTotal = 0;
var HazWaste1 = 0;
var HazWaste2 = 0;
var HazWaste3 = 0;
var HazWaste4 = 0;
var HazWaste5 = 0;
var HazWaste6 = 0;
var HazWaste7 = 0;
HazWaste1 = parseInt(document.getElementById('HazardousWasteSentToLandfill').value,10);
HazWaste2 = parseInt(document.getElementById('HazardousWasteSentToWasteToEnergy').value,10);
HazWaste3 = parseInt(document.getElementById('HazardousWasteIncinerated').value,10);
HazWaste4 = parseInt(document.getElementById('HazardousWasteRecycled').value,10);
HazWaste5 = parseInt(document.getElementById('HazardousWasteReused').value,10);
HazWaste6 = parseInt(document.getElementById('BiohazardousWasteSentToLandfill').value,10);
HazWaste7 = parseInt(document.getElementById('BiohazardousWasteIncinerated').value,10);
HazWasteTotal = HazWaste1 + HazWaste2 + HazWaste3 + HazWaste4 + HazWaste5 + HazWaste6 + HazWaste7;
document.getElementById('HazardousWaste').value = HazWasteTotal;
}
If I run a separate function that just sets all form field values to zero (including the first line of this function). The summing works!!! Why won't it work the way I wrote it??? It won't work if I set the default value for the sum field to zero, either...
I'm a complete beginner to JS and have been playing around with a few test projects but I am stuck with one particular part.It simply creates a new text box if you press the Add Text Box button, and removes the text box if you press the Remove Text Box button.What I want to do now is add a usable value to each text box (e.g. the first text box will have the value "tb1", the second "tb2" and so on - so that I can post the data to use it further on.
View 3 Replies View Relatedhow to do you add elements to an array? am looking at section dealing

where you can't add elements to an array, but use a Vector instead.. and
it's very easy to add to it (use add() method..) how to you add
