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...

Is it possible to reference an object in an each loop like you would an array?
I've tried this without success:
I want to display varying company information from a javascript array randomly each time the page is refreshed. My problem is that the each piece of company information must be split up into 3-4 array elements since I have set up spans in the body where the information go accordingly and as such I don't how to randomize that.So essentially the process is:
1. The person clicks on the company name.
2. Relevant information from the array is shown in the div.
But what I want is that on startup, information about a random company is shown automatically. How can I achieve this?
I have the following code but it simply writes the path to the webpage.I actually want it to randomly select the .js code in that path and run it.
View 1 Replies View RelatedI am currently designing a site, and on it there will be affiliate advertising. As i have many different affiliates i want the page to randomly select one of these affiliates' adverts to show in the places that i have designated. Each affiliate has given me some code to drop in to my html page. I was wondering if there was some javascript that would select randomly one of these bits of code and display it on the page load, in effect removing the need for me to continually have to manually update and change the code so that it shows a rotation of these adverts.I imagine that it would be some sort of script that reads from an array (this array has each different advert code in it).

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 am trying to pass text from one select box to another select box. The logic is if 10 are added, no more passing must happen. Also if an item is already added, it mustn't be added again.I am using the for loop to check the existence of an item but it is not working: what am i doing wrong?
Code:
function PassSelectValues(){
//pass values from select boxes to select boxes
var counter;[code]....
why isn't counter incrementing at all? The alert message box does appear saying item exists but the item gets added anyway.
What I try to do is the following..let's say I have this form:
<select name="sSelectMe" class="someclass">
<option value="">select an option</option>
<option value="1">option 1</option>

I have a button that selects all the checkbox.
How do I select all checkbox when running the click event of each?
Im trying to have a click event that replaces an image on the page with a new image that has been selected randomly from an array. I have solved PART of this already (can get the random image to appear).
However, instead of appearing on the page where the old image was, the new image appears in a blank page.
My research indicates that thisblank page location-problem is a result of using document.write in the Function. Therefore, I know I need to find a different way to accomplish this, but am failing miserably.
I have been trying for hours and hours and HOURS to figure out proper syntax for accomplishing this via elements, functions, variables and mootools.
A bit of my research:
I found this---but havent figured out how to implement it in my scenario:

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:
var images = $('#container img'); // my new array
images.get(images.length - 2).addClass('show');

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] ?

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

Basically, i'm trying to re-create the array latlng which searchLocations() creates and submit it myself with pre-programmed co-ordinates in the load() function using searchLocationsNear(latlng);
here I have array :
Code:
l[1.0]='A';
l[1.4]='B';
l[3.0]='C';
[code]...
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:

In a workshop registration system, you can choose 1st choice and 2nd choice workshops. Of course, You can't choose the same workshop for both! How can I implement this with JS?
Code:
First Choice: <select name="ThursAM-First" size="1" id="ThursAM-First">
<option selected> -- </option>
<option value="T1">T1</option>
<option value="T2">T2</option>
<option value="T3">T3</option>
<option value="T4">T4</option>
</select>
Second Choice: <select name="ThursAM-Second" size="1" id="ThursAM-Second">
<option selected> -- </option>
<option value="T1">T1</option>
<option value="T2">T2</option>
<option value="T3">T3</option>
<option value="T4">T4</option>
</select>
I've a function build in PHP that return this JSON: [URL]. In the HTML page where this PHP function is called via jQuery AJAX I have this code: [URL], this populate two select as you notice, something like this: [URL], But I need the same but in this way: [URL] value come from Json array position.
