Create 2D Array Driven Drop Down Menu?
Oct 18, 2010
What I'm trying to do is create a document which allows you to select a size of box from a drop down menu, and then select a size of product to go into the box on a second drop down. The products on the second drop down menu will be allocated based on the box size that you've selected to make sure that you can only choose products which will fit in the box you've selected.
In order to do this I've set up a 2D array, which lists each product and which boxes they will fit in using 0 for no and 1 for yes. When you select a box size from the drop down a value appears in a text box next to it (1, 2, 3, or 4) and what I need to do is use the number which appears in this text box to pull data from the array to populate the next drop down list. i.e. If option 2 appears from the first drop down selection then the second drop down should be populated with data from column 2 of array (In this example 1212, 1515, and 2020 would be shown in the second drop down)
Im having trouble with the Java script to pull the values from the html text box in order to manipulate the array. If you look at the function 'top_biochill_addOption_list()' you will see that the second drop is populated here from row [itop2][3] of the array, which means the second drop down is permenantly populated as if option 3 had been selected from the first drop down. I need to get the value selected from the first drop down as a variable and replace the '3' in the above statement with that variable to get this to work but I have no idea how to go about that.
Hopefully all will become clear when you see the code. As I say, I am very new to Javascript so I'm sure this code is probably messy and inefficient, but with that in mind I'd appreciate replies being in simplified terms so I can understand what you're getting at, or if anything gets re-written then a brief explaination of whats going on would be handy so I can understand what the code is actually doing!

I have an associative array that I need to loop through, allbills,
however, each element in this array requires processing by the user and
I need to capture the users actions on the element and then return to
the next element in the list but suspend looping until I have the users
desired action...
For example,
for(mybill in allbills)
{
GetWhatToDo(mybill); // gets the information about what user wants to
do with the currentBill
}
The problem is that the function "GetWhatToDo" doesn't "block" so the
loop completes without waiting for the users input from GetWhatToDo...
So, my thought was I need to design things more 'event-driven' and
handle things like so:
function handleABill() {
mybill=GetNextBill();
GetWhatToDo(mybill);
}
A "Next" button inside the popup generated by GetWhatToDo will have an
onclick event that calls handleABill again...
The problem is that I can't figure out how to write GetNextBill so that
it maintains the state of the loop through 'allbills', especially since
'allbills' is an associative array and I can't keep track of the array
index. The only thing I can think of is to initialize a regular array
from the associative array and keep track of the index number.

I need to create a currency converter using a drop down menu. Firstly i needed to do a regular expressions check to make sure only numerics are entered and I got that. The one thing im pretty confused on is how to do the calculations in the actual function.

I'm looking to create a drop-down menu with rather long option titles. The problem is that I want to restrict the boxes size otherwise the size changes to the length of the longest entry. When I use the length attribute, it forces the drop-down to be a certain length, but it also cuts the sentences in half when I drop the options due to the option box being the same length as what I set the drop-down menu's length to be.
Is there any way to set the drop-down menu's size, but have a different size on the option menu that is displayed when the drop-down menu is clicked?

Trying to develop drop down menu... I'm showing a div, then hiding it. It works perfectly, but I need to set a time delay... that's where the problem exists. When I add SetTimeout() to create a delay, it no longer runs correctly...
Here is the code.

I've been beating my head against a wall for a few days trying to get this working. I'm trying to create a dynamic menu where a user selects one item and another select list is shown, then another and another (and so on). Here is my JS, it *should* be taking the ID of the div, comparing it to the selected value and then showing another div by settings it's class property to visible:

I currently have a Drop-Down menu, which has headers you click on to show the links. This menu only allows one drop to be expanded at a time, and can be viewed here [url].
I would like the headers to be able to have 'sub-headers' inside, which also drop-down,to reveal the links. I want them to have a different header colour, and to have the same rule where only one can be open at a time. while keeping the rule with the main headers.

The purpose of the code is to slideToggle open one of two hidden sub-nav bars when either of two different menu items are clicked upon - instead of a drop down menu. What doesn't work is the hiding of the div that is not required, if it is already open. Viewing in firebug shows that the appropriate classes are being applied - I suspect the reason is that slideToggle has been somehow set and cannot be unset via another object - but perhaps that is not it at all?
$(document).ready(function() {
//add .toggle function to appropriate li element
$('#hozmenu li:nth-child(4)').toggle(function () {
//set 4th menu links colour to be green whilst div is shown
$('#hozmenu li:nth-child(4) a').css('color', '#95d890');
$('#toggle_nav_services').removeClass('toggle_show');

I actually want to make a horizontal drop down menu with a sub menu.As far as I have researched, I think that it can be done by JavaScript. I have searched for some java scripts but they are very long and complex.
That made me wonder that for a funcitonality like a Drop down is so complex?
So here is my question : Is there any JavaScript that can be applied for drop down menu exclusively? Which just presents logic of drop down solely?

I'm building a drop down menu like [URL] or [URL] or [URL] the effect I'm trying to achieve is to have the top menu item showing a background image via css and create a stylized design with the sub-menu. Using CSS when I hover over the sub menu the background image of the top item disappears. So I'd like some guidance with javascript on how to keep the back-image while hovering on the sub menu.

, I'd like to think this is fairly simple but unfortunately my knowldege of jquery is limited to using prebuilt scripts and changing a few variables to get what i need. I created a drop down menu with a slide down/up animation for submenus, which worked out just as I wanted. I ran into troubles though when trying to add a nested menu to the drop down, but with a slide animation going from left to right. I'm sure my explanation isn't very clear, so please take a look [URL] The nested submenu I am speaking of should only open when hovering occurs on the 'Item 01' link, but as you can see it also opens when hovering over the buyers link. Secondly, my attempt to slide from left to right on this ul is not working, it seems to be sliding down even though this was not defined in the code.

I am trying to create a specific menu using jQuery where i want to toggle a clicked menu item. I used toggleClass to accomplish this. All fine and well, but what i want is that once i click a menu item, the previously clicked item should have the active state/class toggled off.. The menu is variable. (I tried and tried and searched all over the internet, but i cannot find it... spent 5 hours trying to combine various selectors and if/else statements, but it did'nt work.)

I am trying to create a drop down list which depend to the value selected from the previous drop down list. I can add it without problem, but If I change again the value of the first drop down list I would like to remove the previous drop down list generated from the first value. If I try to remove it when I create the element, it even does not create the element, the remove element function seems to work because when you click on the remove link it works.

If you double click on a empty form box a drop down menu will appear .
But if the form box has text content - then double clicking on the form
box has no effect and a drop down menu doesnt appear .
Or at least it doesnt in IE v7 .
A google search only really brought up the usual beginner type of form
tutorials .
onDblClick=whatever()
I assume i'm looking for a line like the above that i can add to the
<inputtag - or some other suitable piece of javascript to do the job.

I'm currently redesigning my site, and I have a small quandary.[URL].. Unfortunately, not everyone has the same size monitor as me, therefore sometimes the drop-down menus get cut off. Is there a way with this script for it to auto-detect if it's going past the bottom edge, and when this happens it'll go upwards instead?

HTML Code:

so is it really possible to have a javascript app that runs when a
"go" button is clicked (ie requiring a <FORM> tag) inside a form with
a "submit" button? seems so simple, can't figure it out without doing
illegal nested forms.

I have a CSS driven zoom feature which shrinks a large image down to a specified size and when hovered over, the image enlarges to its full size. I need to be able to either make it stay opened (enlarged) when clicked, unless it is clicked to close OR to have the hovered (enlarged) image on a time delay to stay open for a specified amount of time.
I have already tried 2 scripts that I've found, but they are very over-complicated for what I need.
I thought, I'd only need to put something in the <a> tag or <img> tag, but I'm so new to Javascript and it is wearing me so out that I'm exhausted.
I did, however, get the effect that I wanted when I applied a:Active, instead of a:Hover) - It's just that can't get the image to close upon a second click.
My guess is that I need a js with an if open then onclick close it - but I'm not sure how to construct it or exactly where it wiill go.
Here is the CSS that operates the zoom (external CSS):
Code:
Here is the markup for the image:
