Correct Syntax For An Nested Array Where Each Array Element Has 3 Elements, A Number And Two Text Strings?
Sep 17, 2010What 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"',....]
Does A Form Element Know Its Own Index Number In The Forms[].elements[] Array
Aug 24, 2010I have a form element that looks like this:
<input type="text" onchange=doSomething(this)>
and a function:
function doSomething(theField){
}
I know that within the function I can access properties of the field (e.g. theField.name and theField.value). But how do I access theField's index number in the form's elements[] array -- from the "this" reference that was passed to the function? I.E. if this field is elements[3], how can I get at that 3?
Comparing Array Values To Select Unique Array Elements?
Apr 10, 2010This 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.
Shuffle Array Elements (3 To End Of Array) In Random Order
May 6, 2007I'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.

Take X Number Of Elements And Organize Them Into A Table?
Sep 9, 2010I'm trying to take X number of elements and organize them into a table.For example, if I had 7 elements, I'd want 2 rows of 3 and 1 row of 1. If I had 15 elements, I'd want 3 rows of 5, and if I had 11 elements I'd want 2 rows of 4 and 1 row of 3.I'm drawing a total blank on how to go about solving this logic problem. Has anybody come across this problem themselves and solved it?
EDIT: Maybe a little more info would do you good. I'm generating an unordered list and I want the LIs to be as large as possible. It sounds almost like calculus, but I need to figure out the largest size of the images I can fit into a given area when I have X number of images.
Get The Number Of Elements Inside Another Element
Nov 27, 2011I'm working on an exercise I need to have finished pretty soon. The concept is simple: online bookstore with cart etc. It's written on php, using JS and mysql.
Each time I view a book's details, I can add it to my cart, where I can also alter it's quantity.
The code for my cart is this:
PHP Code:
As you can see, each time I choose a book to add it to my cart, a new span will be created, to hold the info of this book. What I need to do with the ManageItem js function, is to update the total cost at the bottom of the page, but I can't seem to be getting anywhere.
Here is what I've done so far:

Long Number To Array?
Feb 7, 2011How do you take a long number such as Math.PI and break it out into an array? code...
I suppose that because of the decimal you would have to convert it into a string first? It would be ideal if I could keep the number as a number without converting it to a string, but I'm not sure if that's possible.
Every thread I've found online so far seems to indicate that you need a delimiter between the string you want to split up - that you can't just put every character of a string into an array... but there must be a way.

May 2, 2011i can scoured but cannot find a way to simply iterate an amount set by a number. both .each() and for(); seem to require the length of an array.
in php you can say if(startNum; is less than or equal to toNum;plusOne) but that doesn't work the same way. is there any way to iterate through something like this, using the javascripts for loop?:

var quantity = 20;
