im just doing a little test and this might seem like a really stupid question but i cant figure it out...all i simply want to do is take all those numbers and get the sum then display the sum in a document.write in theory i should get 10 but i dont and idk why i have tried many many things
var numbers = new Array();
numbers[0] = 1;
numbers[1] = 2;
numbers[2] = 3;
numbers[3] = 4;
I am implementing several scriptaculous sliders in my app... and one thing I can see being an issue is setting their "values" property to limit the selectable values.
This property takes an array of integers representing the allowable values. Unfortunately without this property, the slider will allow you to select a decimal value, so I can't just use a min and max if I only want integer values output.
Creating an array for a small data set is simple: for example "values: [0, 1, 2, 3, 4, 5]"
But some of my sliders will range into the hundreds and need an array of hundreds of allowable values. Is there a simple way to generate an array of 0 to 100 integer values (or more). I know I could use a for loop but it seems to me there might be an even easier way, though I cannot find it.
I would like it to fit in a code block like this:
javascript Code:
var s1 = new Control.Slider('handle1',
'track1',
{
axis:'horizontal',
[Code]....
EDIT: for further clarification, I found that PHP has a range() function that does exactly what I want. Anything comparable in Javascript? [URL]
I have an array holding 100 randomly generated integers between 0-9 inclusive...firstArray[99]
how do i use a second array to keep count of how many times each integer is generated..secondArray[9]
I have an array containing numbers. I want to order this numbers contained from major to minor in order to print them .. Here's what I have done:
var arr = new Array(6);
arr[0] = "10";
arr[1] = "5";
[Code]....
But I get no alert and a "myarray.sort is not a function" error.
Write a program which takes a series of positive integers as input : 1, 2, 3 …
When input is complete, as indicated by entry of an end of data flag ( -2), the program will output the largest of the entered values.
how to do you add elements to an array? am looking at section dealing
with arrays in JS Bible, can't find how you add to an array.. in the
last few years I've been doing much more Java than JS, am used to Java,
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
elements to an array in JavaScript..
I looked up array obj, don't see method to add to array.
I want to make a script that will insert all text type inputs into an array. From there I want to be able to call them and edit them. Here is what I have so far and it is not working.
var phone1 = '702'
var inputArray = new Array();
var inputs = document.getElementsByTagName('input');
inputs;
if (input.type == 'text') { inputArray.push(inputs.id); }
inputArray.reverse();
inputArray[0].value = phone1;
I have a issue that is getting me frustrated I a large arrays of profiles. So I take the necessary arrays out of profile and add them to an small array called items. Then I want to take elements out of the new items array and place the string values into a select array the issue is the default if in the last for loop it will not work it only ever returns the entire string/ array
Code:
var select =[];
var profile = [];

I have a number of DIVs that I want to make 'selectable' on click, which means that I give the DIV you click on a class (just to show it's selected) and save its ID into an array. When I click on that DIV again, the class should be removed and its ID should be removed from the array as well. My code goes like
var selected_items = new Array();
$(".selectableDivs").click(function() {
if($(this).hasClass("selected")) {
[code]....
But the alert at the end of the code always shows my a list of all divs I ever selected, even those that I unselected again. The IDs are just not removed from the array. Is that maybe because items saved in the array are not exactly $(this).attr("id") anymore?
I want to post a form and reload the results $("#shoppingcart").load("/catalog/shoppingcart.php", $("#"+frmId).serializeArray());
This works fine, but I would like to add a key and value to the array. How do I do that?
Resolution:
<script type="text/javascript">
I have an array in a seperate.js file that I need to step through a FOR loop to grab all these values and add them together.
Here is a small sample of the array's:
Here is the loop step through that I have:
I am stuck on how to grab each amount index and add them together to save them as the amountTotal variable.
Since the Array.splice() method isnt supported by IE5 here's a script with an add function and a remove function.
function remove(nr) {
var nb = parseInt(nr)
for(x=nb;x<myArray.length-1;x++) {
myArray[x] = myArray[x+1]
}
myArray.length += -1
}
function add(nr,value) {
for(x=myArray.length;x>nr;x--) {
myArray[x] = myArray[x-1]
}
myArray[nr] = value
}
You can test it out by including the following html, and an array in the script (here named 'myArray').
<body>
<form>
Nr to add/remove<input type="text" name="nr" /><br />
Value to insert <input type="text" name="val" />
<input type="button" value="remove" onclick="remove(this.form.nr.value)" />
<input type="button" value="add" onclick="add(this.form.nr.value,this.form.val.value)" />
<input type="button" value="View Array" onclick="aA()" />
</form>
</body>
</html>
And this small function
function aA() {
for(x=0;x<myArray.length;x++)
alert(myArray[x])
}

View 2 Replies View RelatedI 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'm creating matrix of values like this:[code]Usually when i want to access position like Matriz[0][0] y retrived the value "", now for some reason when i debug appears "indexOf" at the beggining and when I access Matriz[0][0] I get "undefined".Someone knows why is happennig this, i'm using IE 6

I'm playing arround with integers.
1.000.000,00 // throw error
1,000,000,00 // throw error
1000,00 // success
100.00 // success
And on success I have to get all numbers before the dot or comma .
I'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.

View 2 Replies View RelatedI'm trying to solve a problem with JS textbox array without success.
I have two buttons in my page: PLUS and MINUS; at every click on PLUS a new
textbox named 'dear' is generated. So, if one clicks, say, 3 times the
output is something like:
dear[0]
dear[1]
dear[2]
The length property is accessible; alert(dear.length) gives Ɖ', correctly.
The prolbem is that is not possible to delete a textbox, clicking on MINUS
button. The thing I'd really need to do is to delete from the array (and in
consequence from video) the last textbox created, when one clicks on MINUS
button.
Pop() and Splice() methods do not work, unfortunely...
This is the exact code of my page:
<a href="#plus" onclick="john.innerHTML+='<li><input id=dear type=text
size=50>'">
[PLUS]
</a>
<br>
<a href="#minus" onclick="alert(dear.length);dear.pop()">
[MINUS]
</a>
<ul>
<div id=john>
</div>
</ul>

I've got this little chunk of code running on my freelance portfolio site - on each page (different sections of my portfolio) I have 6 thumbnails and a full sized graphic with some descriptive info, you click the thumbnail and it switches the graphic and other info, that all works fine.But on one page I have some web stuff and I'd like to make the var 'clientinfo' into a link to go to the client's website. I know I need to add an array with the website links, but then I'm not sure how to implement it into the html, I've tried various things I've found on here but I'm not getting anywhere on my own.

Years ago I created HTML that employs checkboxes and textboxes. I am now writing JS with the intention of adding flexibility and limiting redundancy. I am not sure I truly understand how to correctly interact the two though. For example, one of my scripts have arrays that contain the names of the checkboxes and textboxes, with a 'for' loop to document.write() them to references within the HTML code.This does not seem to be working for me though. Here is what I have thus far (in short):
<script language="javascript">
var teamNames = new Array(3);
teamNames[0]="South Africa";
teamNames[1]="Mexico";
teamNames[2]="Uruguay";
[Code]...
I've left out a lot of the code (to include the teamAbbr array, but you get the points. I've tried moving the JS within the HTML body and playing with the reference syntax, but nothing so far.
