JQuery :: Find Position Of A Clicked Item In An Array?
Jan 12, 2010
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()?

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 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.

I'm trying to create a horizontal dropline menu out of an unordered list. List items can have one unordered list child. I want to add a click event on all li:has(ul) elements. The pseudo-algorithm I'm thinking of is as follows:Find all other li:has(ul) elements on the page.For each, check if they are displayed.If displayed, hide it.Then, if the clicked li is displayed, hide it. Otherwise display it.Only one li:has(ul) element should be displayed at a time.
<script type="text/javascript">
$(function(){
$('li:has(ul)').click(function(event)
[code]....
What I have doesn't work because in the .each() function, the clicked li is also evaluated. So, if the clicked li is already visible, it gets toggled inside that function and then toggled again outside that function.

in jCarousel i have a list of items, what i would like to be able to do is when the user clicks on an item (say the 4th visible item in the list) the carousel would scroll so that the clicked item becomes the first visible item in the list.

I have been working on a dropdown menu using Clarklab's Tutorial:The only problem is that this tutorial only shows how to create one dropdown instance.It's in use here:My issue is that when I click on one menu item, all the submenus open up. Is there a simple fix that I just haven't figured out yet?My instinct is to give each ul it's own id, but I'm not sure how to direct the jquery in the header to work with individual elements.

I'm trying to find the currently clicked index of .accordion_trigger from within another element.
When inside the .accordion_trigger click event I can simply do the below to get the current clicked index:
Code:
$('.accordion_trigger').click(function(){
var index = $('.accordion_trigger').index(this);
}
return false;
});
Obviously this doesn't work when called from within another element. I understand that 'this' is part of the problem but can't seem to find a way to form the code in such a way for it to produce a valid result. Thus far I only get -1 or 0.
When .accordion_trigger is clicked it has an "$(this).toggleClass('active').next().slideDown();" applied so in theory I shold be able to search for which of the .accordion_trigger's are "active".
I've also tried doing this via the below method but to no avail:
Code:
var current = $('.accordion_trigger');
current.each(function() {
if ($(this).hasClass('active')) {
[Code]....

So, I have this menu set up that reduces the opacity of all but the hovered link. It works fine, but it's a video playlist, and I realized that I need to make sure that this style persists after the link has been clicked.I can figure out how to add a class on click, but how to combine the two? How can I set it up so that, if the link doesn't have the class .selected, the opacity will be at 0.3. Unless, of course, it's being hovered over.I'm in a little over my head here. Here's what I'm working with:
Code:
jQuery(document).ready(function() {
jQuery("#links").delegate("li", "mouseover mouseout", function(e) {
[code]....

I currently have a website with a number of menu items, many of which result in the main site being redisplayed but with an iframe being inserted somewhere within the middle of the page. The iframe is initially loaded as hidden but there is a JavaScript 'onload' routine which calculates the height of the iframe and then makes it visible in order to avoid the iframe showing scrollbars since the content of the iframe is variable.
Roughly, things look like this:
Menu button: reloads main page and passes one or more parameters, e.g. [url]
Then elements of the main page including the menu are displayed. Then, if specified by the relevant 'func' parameter the iframe is shown using code similar to the following:
This works fine but I was wondering whether there is any way of using jQuery such that I don't have to reload the page when the menu item is clicked. In other words, you'd click on the menu item and the relevant iframe would be inserted within the middle of the website, automatically sized.

The mouse position tutorial has an example of how to find the click position within an element. How do you find the click position within the viewport?

I have a table that looks something like this:
<tr id="1">
<td>Name</td>
<td>E-Mail</td>
[code]....
With multiple rows. Each row has a unique ID (numerical). I need to be able to click on an a.accept, find WHICH one was clicked (which row it is in), and get the ID of that row. I've been looking around and I found parent(), but I'm not sure how I can specifically get which accept link was clicked.

Let's say I have a table with 5 rows;
<table id="tbl">
<tr><td>Please</td></tr>
<tr><td>help</td></tr>
<tr><td>me</td></tr>
[Code].....
Now if someone clicks on the row with content "help" (2nd), I want to catch the click with jquery .click() and know within the jquery code that the user clicked on the 2nd <tr> element within table#tbl.
If someone clicks on the <tr> with content "this", my jquery code has to return 5, because its the 5th row.

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 a vertical menu consisting of CSS rollovers. When clicked, each one dynamically loads a new Flash movie via Javascript, within the same page. This works fine. However, what I would really like, is to have each menu item highlighted after it has been clicked, to show the user what is being shown. This could be the same image as is displayed in the active CSS state. Does anyone know how I can do this? Because each link is simply dynamically loading flash movies, and not going to a new html page, I can't simply add an ID element.
CSS:
#navlist {
font-family:Arial, Helvetica, sans-serif;
font-size:.8em;
font-weight:bold;
list-style:none;
}
#navlist a {
display:block;
