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'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.
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 something like this:

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?

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

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:

here I have array :
Code:

l[1.4]='B';
l[3.0]='C';

And time :
Code:
var time = document.getElementById("time").innerHTML;
But making it
Code:
document.getElementById("k").innerHTML = l[time];
puts false into mine div, time changes alot and is in same format as array names.That function is repeated every 100 microseconds :
Code:
window.setTimeout(myFunction, 100);
Trying to do that in console tells me that doing it like : l[document.getElementById("time").innerHTML] gives me some value while using time variable just undefined, no matter it's same value Next problem I would want my text appear somehow like this when time is 3.0:

I've tried this without success:
I want to randomly select one item from all those that are checked in a list of checkboxes. The checkboxes all have the same name, "members". I think my problem is creating the new array of names - only those that are checked - from which to randomly select the single item. Based on the below, if I select the top and bottom items, I get something like: Joe,,,,,,,,,Bob as my array output for checkednames code...

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.

$("div#carousel a").each(function(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];
Hi, 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.
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()?

the first function(start: function ..) displays an attribute (title) of the dragged item once the sorting starts. supposedly, the second function (stop: function ..) would display the same attribute but of the item replaced by the dragged item once the sorting stops.

I have some js code in which a click on a nav arrow causes list to be walked up or down and hilighted. Partial code is below. The problem is that when I get to the end of the list (e.g. there IS no next()), I want to skip this part of the code and actually hide the right arrow. I have no problem with the hiding part - I just want to set a flag when I have traversed the list to the last item.
