Is there a best way to reorder a jquery group/array, eg bring one item to the first position? Should you do it with a normal array.sort() or splice(), or is it possible with an internal function map()?

View 2 Replies View RelatedHi, i'm creating my own image gallery using jQuery, and there is a set of thumbnails at the bottom. The thumbnails have been put into an array, using jQuery, but what i am trying to do is to return the position of any clicked thumbnail in that array. i.e. when the 3rd thumbnail in the list is clicked, return 3, when the 5th thumbnail is clicked return 5 etc....
This in turn will dictate which item in another array (the main images array) will be displayed.
I have created a little script that is supposed to add another item to a radio group and set the new item as selected if none of the other items is selected. It works on initial load of page, but if I press refresh, the checked value of the radio group shifts one place to the right on each reload.[code]The code has some special names and labels.. Thats just because it comes from some generated code from another application.

var index = $(attribute).index(this);
However, this returns -1 for all selectors I pass to it in the variable. Why is this? Is there another way to find a div's position within its container easily?
provide me with code to make a collapsible menu? What I'm looking for is a vertical menu, that will open up the sub-categories upon a mouseover. Clicking on the menu item will bring them to the specific page. Oh, and this might not matter, but I'd prefer if I was able to style the menu to fit with my site theme.

I'm trying to grab values from a set of arrays based on the value returned by my select box.
**Caveat - this is not an area I have any real experience with**
My arrays look like:
Code JavaScript:
I then need to test for each, then associate with one of my fees arrays, then grab each of the values in the array and write those values to elements within my page.
I'm then doing this to evaluate for each degree
Code JavaScript:
I need to first figure out how best to import all of these 60+ arrays and then in each of my conditions pull out each value and write to my page.
There is a unique 1 to 1 relationship between each degree and array so I can't consolidate as the values for each degree differ slightly.
I have something like this:
var images = $('#container img'); // my new array
images.get(images.length - 2).addClass('show');
error is like this:
Error: $("#container img").get(images.length - 2).addClass is not a function
Is it possible to target certain <li> in an unordered list by index with jQuery? I thought maybe I could use .index but was not able to get the syntax right. I thought maybe something like this would work but is has not:
$("#mycarousel > li").index(i).css("margin-right", "5px");
I am very new to javascript/jquery so bare with me. I am using this loop code below with a populated array called "listarray":

Is it possible to reference an object in an each loop like you would an array?
I've tried this without success:
I have a question about removing an item from an array.I am looking to remove an item from the array based on the property.Ie.arr = [{a1: 1, a2: 2},{a1: 3, a2: 4}, {a1: 5, a2: 6}]remove first item from array because a1 = 1.I am not entirely sure how to do this. I tried messing around withgrep a bit, but that didn't turn out well.
View 3 Replies View RelatedI don' t know what I'm missing here..
$("div#carousel a").each(function(i) {
$(this).click(function(e) {
e.preventDefault();
console.log(myArray[i]);
});
});
it doesn't loop, it always prints the first item in the array (there are 18 <a>'s inside div#carousel, and 18 items in the array...)
I have an unordered list that I am using as a menu. This list contains sub lists.
I found out how to get the index of the primary unordered list item that is being hovered but I am not getting the syntax correct to reference the individual items of this listto get the HTML, the position, height and lengthof this item.
$(" #nav li").hover(function(){
// Locate the index of the singular list item that is being hovered
var index = $(this).parent().children('li').index(this);
// This is incorrect
var $itemObject = $(this).parent().children('li')[index];
I know that there are some really nice jQuery UI. However, I'm really new to jQuery and I need to save the order into a SQL Server database so that next time if the same user comes back to the site, the picture will be in the same order that he/she reordered it previously.
View 1 Replies View RelatedThis is a combination of jQuery and a PHP problem so I'm not 100% certain where to post it. I am working on method to reoder a list that comes from a database. When the lists is displayed, it will be ordered by a "sort" column. The user can drag/drop the list to change the order, and I want the order to update the sort values in the database.I found a script that provides a decent starting point, but I am not getting the results I want.
1: It is able to reorder the columns, and save the results which is good.
2: It is saving the results as "0,1,2,3" rather than reordering the numbers from the "sort" column. (< this is what I need fixed)
EG: Name > Sort
Apple3
Orange 5
Pear 13
Kiwi 105
If I reorder these in the reverse order using the script, I end up with the following in the database.
Apple 3
Orange 2
Pear 1
Kiwi 0
Yet what I want is,
Apple 105
Orange 13
Pear 5
Kiwi 3
how I can get it to work with the existing "sort" values, rather than serializing and starting at 0. Here are the script files I am currently working with for testing.

Code:
CREATE TABLE `menu` (
`id` int(11) NOT NULL auto_increment,[code]....
What's the best (i.e. fastest) way to find out if an array contains a given
value? Other than looping, the only way I know to do it is to use an
associative array/hash instead....
Is there a better/faster way?
I.e if I have a list of names, what's the best way to find out if the aray
contains "jane"?
I have two different arrays with the same number of element. The 1st array holds the ID's and the 2nd one holds the Items....i want to use both of them in a Jquery autocomplete plugin.. showing the the 2nd one values but getting the value of the 1st arr.
I was wondering if there is a way to combine both in one in Javascript.
like Arr3 =[arr1, arr2] where i display arr2 elemnt and pass arr1 elements?
This randomising function is like a coin toss, it gives a numerical result and displays it:
function Ran() {
var c = Math.random();
return (c < 0.5) ? [0, show0()] : 1, show1()];
}
I want to extract the numerical outcome, 0 or 1, from this and from two other similar functions, sum them, and then run more functions based on the possible sums.
What is the syntax for getting to the numbers? something like
var n = Ran().[0] ?
I have an array of 6 items. I want to select 2 at random and then add an item to the start. Here's my randomiser [code]
View 2 Replies View RelatedI am currently putting together a trivia game and I have stored several items in an array for example the questions, and the answers, points value... etc.
but my dilemma is I have to assign an "id" to the elements in the the array so i can use the function getElementById() to call the information. I do not have a clue how to do this.
*** also the second issue is my array is showing an error as UNDEFINED BUT i have declared it in "var triviaArray"
this is my array:
var triviaArray = new Array [
triviaArray["What's the capitol of Canada?","TORONTO","VANCOUVER","OTTAWA","QUEBEC",10,"choice3"],
triviaArray["How old was Michael Jackson when he died?","35 yrs","50 yrs","40

[41, "The bird flew into it's cage"]
[33, "He drew fire from Joe"]
[33, "Roger asked her her name"]

and i wanna to add more items in special values , but doesn't work code...
