I would like to display the elements in my array but it is NOT working. Here's my code:

trying to fix this code up to display the following line at the end:The maximum distance was 6km run on Tue and Fri (the word 'and' not required)So far I have got it to only describe Tue and it stops before it gets to Fri and i have no idea how to get it to write it out in any case.The code also has to work if you comment the lines 22 and 23 where it should display the line The maximum distance was 5km run on Frisorry for simplistic code im very new to javascript!

What is the correct syntax for an nested array where each array element has 3 elements, a number and two text strings?
Code:
array = ['1, Old Man, Old Man','2 Black Sheep, Black Sheep',....]
should the text strings be in double quotes("")?
Code:
array = ['1, "Old Man", "Old Man"','2 "Black Sheep", "Black Sheep"',....]
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'd like to reorganize the third, fourth, fifth and sixth, as well as any
elements thereafter in an array in random order:
var a = new Array('first','second','third','fourth','fifth','s ixth','etc')
In other words, the first, second and third element should remain in
position 0, 1 and 2, while the fourth, fifth and sixth, etc. should appear
in random order.
I'm hoping this is possible or that there is an easier way to do this. I'm having an issue with displaying data from one array that contains information about users in a table that is controlled by a different array.Is it possible to do this or is this use of arrays to display the data the wrong approach?
The table is located on one webpage, I simply want to extract one piece of information that I have placed in the initial array as part of the login script that contains user information (for validation for login etc) and display it in a table on the new webpage that is opened as a result of successful validation of the user details. I'm completely stumped and after many attempts I just can't seem to get it to work.
So i've got a form that adds an element onto the page. This is working. When I try to remove said elements, that works. But the same 'delete' button doesn't work on elements not generated by javascript.
Code JavaScript:
function destroyQuickTask() {
$.post($(this).attr("href"), null, null, "script");

I am trying to display some xml elements that are formatted like [code]...
I can see that this is because of the [0] in the getElementsByTagName - if I change it to 1 or 2 it shows the 2nd or 3rd set of directions. But I want it to show all of them.
Is it possible to have one of nine elements of an array, each containing code that will fill in a square in a tic-tac-toe game, randomly chosen then the code executed?

Array.prototype.sum = function() {

I would like to know that how can I show the value of all the elements in array "amount" in total field?
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 do a search and get the following in xml:
<user>
<exec>
<entry>Value1</entry>
<entry>Value2</entry>
<entry>Value3</entry>
<entry>Value4</entry>
<exec/>
<user/>
How is the easiest way to find the number of entries in the array and
how can iterate over each value to test if the given value matches
another variable?
I have an array as such:
Code:
var Array = ("1|This Item","2|That Item","1|Here Again",'2|Once More");
I need to be able to count how many elements have the 1 and how many have the 2.I know that I can do the loop
Code:
for (var E in Array) {
(var a, var b) = E.split("|");
if (a == 1) {CtA++;} elsif (a==2) {CtB++;}
}
I am creating an array based on form elements. I then am trying to create an IF (and nested IF) statement to check if the fields are empty and then with the nested IF statement use certain fields to create mathematical functions.
So far I have this:
function QuantityMWh(form) {
var formchk = document.forms[0]
for (i = 0; i < formchk.elements.length; i++) {
if (formchk.elements[1].value == "" && formchk.elements[2].value == "") {
[Code]....
It's only checking the first field and not the second, and vice versa. i.e. if only one field has text then it passes.
I have this simple code to put elements into an array

I have an array in javascript which has n elements. The number n is not known. How to delete all the elements from the array?
View 1 Replies View RelatedI 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.

First of all I need to define an array of 3 elements. Each element is associated with a different first name. Then I shall realize a first function to add a name in the table. The function takes as parameter the table previously created and return it containing an additional element whose value is the name that the visitor wants to add. I must use the dialog box prompt so that the user can specify the name he wishes to add in the table.
I shall also perform a second function which will display the name that is included in the different array elements. This function will also take the table in parameters and proceed with setting the display name with a dialog box alert type that contains all of the name separated by ";".

I have a form that has an array of input values:
I do this so I can loop through the values in php... now...that's the easy part... the hard part comes to this:
Next to each of those boxes is a search button that allows the user to open up a popup window that they can search for an item, and select the item. Once they select the item it should populate that particular input box with the selected item. I can easily do this with a uniquely named input box, but can't seem to figure out how to do it with an array of input boxes...
I've been trying to hack together a certain javascript lately, but as a complete novice I don't quite know how to achieve what I want.
Basically, I have a few information-request forms on my site. Once someone has submitted the form, I'd like the confirmation page to set a cookie, using JavaScript. Once the cookie has been set, I'd want to be able to hide page elements that have a particular ID or CSS class. Obviously, I can hide these elements using display:none. But, that only needs to apply to these elements if the cookie exists. If there is no cookie, the elements obviously need to show.
I've done quite a bit of research about JavaScript and cookies, but unfortunately have not found anything that works "out of the box" or that I understand well enough to hack together. What terms or concepts should I be looking for to learn how to do this? Or better, is there a script already out there that will work? If I could only find a working example, I think I could understand much better.
I have an array with three dimensions. There are 10 elements in each dimension so I've got a 10x10x10 cube. How can I combine all the elements from one dimension into one layer so I can display the whole cube in a 2-D view?
View 14 Replies View RelatedI have a little problem (maybe I'm just to tired to get it -.-). I'm trying to access elements which are descendants of another element. I do it by using
containers = $('.likeReceiver .powermail_radio_inner'); When counting the elements with .length it says, there are three elements. So far everything is working.However, each time I try to access the elements all I get is a message which says "Undefined".

I have a fieldset with a bunch of input's inside.
I am wanting to put all of these elements inside the fieldset into an array.
Then once I have that array use a for loop to iterate through each of the elements values and display them with alert.
This is what I have tried, but am expecting to be a fair bit off the mark.
Code:
I use a very handy function (onsubmit) to validate empty fields in a form:
PHP Code:
function validate_form(){
var x = document.getElementById("form1");
for(var i=0; i<x.length; i++){
if((x.elements[i].value == "") && (x.elements[i].title)){
[Code]....
It worked like a charm, until I had to change a dropdown dynamically with ajax. I have two dropdowns, the second being populated with ajax (php, mysql) by the option selected in the first one. The second dropdown has the title attribute filled so the previous function can validate and ask the user to select something. However, it seems like fields loaded dynamically with ajax wont appear inside the x.elements[] array. I've tested it over and over, it keeps ignoring it. It isn't even in the array. Why?
