How do i declare an empty array?
I need to iterate through a group of arrays and search for a user-chosen word every time.
The problem is i can't declare how many array elements will be needed, such as: new array = (12), because some words inside my arrays, occur more than others.
So i need to decalare an empty array with x number of possible values.
I am looking for a push in the right direction for a few problems i am running into; my first problem is I have to create a script element that contains the function amountTotal which should return the sum of all the values in the amount array. There are no parameters for this function, and I have to add the following commands to it.
1. declare a variable named total with an initial value of 0
2. create a for loop thatloops through all of the values in the amount array, at each iteration of the loop, add the current value of the array item to the value of the total variable.
3. and after the for loop is completed, return the value of the total variable.
The amount array has already been created and populated in a list.js file, I had to first create a script element pointing to it.
This is what i had for my link to the list.js file and funtion :
I have my entire code written but i am trying to break it up and fix my problems 1 at a time: when i open the code, it does'nt display correctly ( which is another problem) but I ran the debugger and it says my total is undefined. ( this is in another section of my code), but I guess my function is wrong somewhere.
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;
[Code]...
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'm interested in putting on a simple, fade, slideshow. I followed the directions according to this link: [URL].
Here's my code in the <head> </head>
<style type="text/css">
.slideshow { height: 232px; width: 232px; margin: auto }
.slideshow img { padding: 15px; border: 1px solid #ccc; background-color: #eee; }
</style>
<!-- include jQuery library -->
<script type="text/javascript" src="[URL]"></script>
<!-- include Cycle plugin -->
<script type="text/javascript" src="[URL]"></script>
<!-- initialize the slideshow when the DOM is ready -->
<script type="text/javascript">
$(document).ready(function() {
$('.slideshow').cycle({
fx: 'fade' // choose your transition type, ex: fade, scrollUp, shuffle, etc...
});
});
</script>
I uploaded the.JS files.
And here's the HTML:
<div class="slideshow">
<img src="[URL]" width="200" height="200" />
<img src="[URL]" width="200" height="200" />
<img src="[URL]" width="200" height="200" />
<img src="[URL]" width="200" height="200" />
<img src="[URL]" width="200" height="200" />
</div>
They are just stacked up, nothing's happening. Check it out: [URL].
As you no doubt know, a link that is generated on the fly (ie by a JS function) and is supposed to invoke a ColorBox (due to a predefined selector) doesn't work as the link didn't exist when the ColorBox was initialised e.g., you have this in the head:
$(document).ready(function(){
$(".frmMe").colorbox({iframe:true, innerWidth:1200, innerHeight:640});
}
Then a link generated by JS at a later time (for example triggered by a users click) like:
<a href="blah.php" class="frmMe">Easter Eggs</a>
Whenever I dynamically create a link like the one above, I re-run the line:
"$(".frmMe").colorbox({iframe:true, innerWidth:1200, innerHeight:640});" afterwards to ensure the colorBox functionality works.
Now however, I have an instance where a link on a parent page like the above is created from within an iFrame (on the fly using JS). Unfortunately however, I haven't been able to find a way to re-intialize the ColorBox on the parent page from within the iframe to ensure that the new link has ColorBox functionality enabled.
I have tried:
$('.frmMe', parent.document.body).colorbox({iframe:true, innerWidth:1200, innerHeight:640});
but it seems to have no affect and generates no errors (yet this follows the format I use to create the link. On the page which is:
$('#updateBx', parent.document.body).html('<a href="" class="frmMe">Glorious</a>');
I understand that there is no need to initialize a variable at the point of declaration. OTH, what is the default type of a [declared] variable? For example:
[Code]...
Does anyone know if there is a way to change the defaults such as number of thumbnails after initialisation? e.g.$('.changeTo16').live('click', function(){//set gallerific stuffnumThumbs: 16});$('.changeTo8').live('click', function(){//set gallerific stuffnumThumbs: 8}); etc...
View 2 Replies View RelatedI'm initializing a lightbox type plugin after an ajax response. The plugin is usually initialized with .ready, but I've read on this forum that .ready won't work after page load or with dynamic loading. Most posts say to initialize right after the ajax response... I've done this and it works for the first ajax load, but not for the subsequent ajax loads. It should trigger the same code every time ajax is called since it goes through the same function, but it doesn't.
Project Info: This project seems pretty simple... There are links that load content into a DIV via ajax... the content is made up of thumbnails that should launch lightbox...Is there a good way of dynamically initializing plugins after ajax load?

I am having a problem to add numbers store in an array.
arrayValues[0][0] = 1;
arrayValues[0][1] = 2;
var col = 0;
var sum;
for ( var row = 0; row < index; i++ )
sum += arrayValues[col][row];
My result is ==> 12 it is defining my sum variable as string. Even I try do do this var sum = 0; to define sum as numeric variable. my result was ==>012.
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:
[{"Id":148,"Text":"excellent","Percentage":18},{"Id":166,"Text":"good","Percentage":25},{"Id":167,"Te xt":"fair","Percentage":30},{"Id":168,"Text":"poor","Percentage":25}]
How can I go about turning it into an array that looks like this (just the last integers)?
[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:
"1","2","3","1","2","3","1","2","3"
What would be the easiest way to dump the values into the other without making it multidimensional?
