Get Index Of Selector?

Apr 2, 2011

Just started to dabble with jQuery I can get the id for a clicked element, but how can I retrieve its index number within the class?

Code:
$(".heading").click(function () {
$("#containContent").slideToggle(100);
//window.alert($("#containContent .content").length);
window.alert(this.id);
});

Hopefully I can do this from the 'this' reference without having to backtrack through the id?

JQuery :: Index() Not Returning Index Of Object

Aug 25, 2010

I am trying to get the index of a li with a specific class. I know I'm selecting the right object because I can apply a CSS class to it (eg change border colour) but when I try to get the index it returns -1. But I know the object exists as I can alter it. :-s

jQuery(document).ready(function() {
var active = $("#tertiarynavigation .bordered").get(0);
var num = $("#tertiarynavigation li").index(active);
alert("Index: " + num);

Z-index - Layers - When "mousedown" Fires - Change The Div#msg Z-index Value From 1 To 3 To Be On Top

Nov 3, 2011

I have a problem with layers. In my example there's a link inside div#msg with 'z-index:1' and a overlay with 'z-index:2'. Now when "mousedown" fires, will change the div#msg z-index value from 1 to 3 to be on Top, so the link become a clickable link.

The question is, it is possible to make the link on top and open it with just one click?

This example can do that but won't open the link!

IE9 Not Respecting Z-index?

May 18, 2011

To position some widgets on a webpage I have used a table. As a background of the table I have set an image.('position: absolute;' and 'z-index: -1;'). But to know where an element is dropped, I have to get the element where the dragged element is dropped on using document.elementFromPoint(x,y);' This is always a table cell, because the table is showing before the image. All webbrowsers are returning the table cell, but IE returns the image element. Two ways it works in IE:Remove the imageSet a background color in the table cells

Dynamically Changing Z-index

Jul 23, 2005

I have a page with 3 divisions overlaying each other. I dynamically
change the visibility to switch between them. On the Mac version of IE
5.1 I am not able to activate the scroll bars after making a division
visible. Only the originally displayed division works. I am able to
click on the data (option select lists) in all of the divisions. There
is no problem when I use Netscape.

I would like to dynamically change the z-index to see if that would
help. Can someone tell me how?

I'm refering to an entry in an array by it's string key, as in
foo["bar"]. Is there a way to get the numeric index of that array
without iterating through the entire array?

What I need to do is find the "next" or "previous" entry in the array,

Changing Z-index On Mouseover?

Jun 29, 2011

I'm having a real hard time trying to get a simple rollover working correctly on my site using inline javascript.

I have an set of five images in a gallery that are covered by one larger image 'Rollover.jpg'. When you roll over the larger image it gets hidden so it reveals the five images below it code below:

<div id="menuRo" onmouseover="document.getElementById('rollover').style.visibility= 'hidden', style.zIndex = -1;" onmouseout="document.getElementById('rollover').style.visibility= 'visible',

[Code]....

i then added the line ",style.zIndex = -1;" so on mouseover the main image would drop below the five images and remain hidden, so that the five images become clickable; and then ",style.zIndex = 1;" on mouseoute, so the image appears back ontop covering the five images on mouseout.

However, I just get this crazy flickering on mouseover now, so I'm wondering if I have my inline code setup correctly?

Setting A Combolist Index And Value

Jul 23, 2011

I have 3 combolist fields ( A, B and C ) each of which has just "No" and "Confirmed" as their only options.I have one final combolist ( D ) which has just "Yes" and "No" as options. "No" is the default selected item and Index0 in the list.The user must select "Confirm" all three ( A, B and C ) lists before they should be allowed to select "Yes" in the final list ( D ).I want to be able to have the system to automatically select and display "No" in list ( D ) if any of the first 3 selections ( A, B or C ) are "No".

I don't have a problem validating if any of the 3 lists ( A, B or C ) are "No" but I cannot get the final combolist to change from "Yes" ( if previously selected ) to "No".I have tried setting the selected index of (D) to 0 and tried setting the selected value of (D) to "No" but if (D) currently displays "Yes" when any of the ( A, B or C ) are changed to "No" nothing happens to (D).Am I trying to do something that cannot be done ?
