What I'm trying to do is when the mouse hover on the level1 class, I want level2 class change it's background color. But I do not know how to reference a subclass.
<div class="level1">
<span class="level2">One</span>
</div>
[code]....
How can I subclass a native class to get my own class with all the
function of the native clas, plus correct instanceof behaviour?
The scenario I'm thinking of is something like
function MyArray() {
Array.apply( this, arguments );
}
MyArray.prototype = new Array();
MyArray.prototype.constructor = MyArray;
var marr = new MyArray();
marr[0] = "abc";
marr.length == 1; // true
marr instanceof MyArray; // true
But this seems impossible due to the Array constructor returning a new
object even when called with my own "this" in the apply() above. Can
this be solved in any way?
I have a superclass where I create a "div" element as a property and then proceed to try and set the element's "id" attribute in a subclass. Interestingly, if I create multiple instances of the subclass with different "id"s, they all end up having the last "id" I specify. I would like it if they retain the individual "id" I specify. Here is the code.
function Drag() {
this.ele = document.createElement("div"); }
function Icon(id) {
this.ele.id = id; }
Icon.prototype = new Drag();
var hello = new Icon("hello");
var goodbye = new Icon("goodbye");
In the following example PositionedRectangle is a subclass of Rectangle, all 3 methods of prototype inheritance seem to produce the same results, method 1 is from the authors book (Flanagan's Definitive Guide 5ed) example 9-3, and method 2 is from his website example 9-3, and method 3 is my own;
// method 1 seems most complicated
function heir(p) {
function f(){};
[code]....
To have all the :hover subclass fade from their passive states, instead of changing instantaneously? i just can t figure if such an effect can be done.

I am new to jQuery and I am reading this book as an introduction. I find it very good, but I came across an example today that doesn't make sense to me. It is an example of the prev() method and is like this:
$("h1").prev() // Sibling elements of <h1> tags
Is this correct? I thought prev() just picked one element so it should be "element" instead of "elements" in the comment. Alsoa sibling of <h1> tags would have to be another <h1> tag wouldn't it? And there are no <h1> tag before all <h1> tags?

I've made a trivial html page to show my problem. This page should take all of the <tr> tags from the first table, move them into the second table in reverse order, and change each <tr> tag's click handler to print it's internal <td> tag's contents.Unfortunately, the function I've set as the click handler seems to be passing a variable by reference rather than by value. I'm sure this is probably the expected behavior, but is there someway to prevent this behavior?If this doesn't sound very clear, hopefully the code I've included will make more sense:
<html>
<head>
<script type="text/javascript"

I have an anchor like that
<a href="#" onclick="showInfo(');" class="nostyle" ></a>
i doesnt have id or class name because i generated it dinamically in xslt.
When i click over it, shows a hidden div that contains other "a id=''close" tag, the idea is change the background color of the first anchor when i click on the close button. But i dont know how i can set the it up. how i can get wich anchor i have been clicked and change.
The following used to work with version 1.3.2
var x = $('#ElementID').val();
var x = $("'#" + "ElementID" + "'").val();
var eid = "'#" + "ElementID" + "'"; var x = $(eid).val();
Only the top one works with version 1.4.1
Similarly the following used to work with 1.3.2 but it doesn't work anymore.
var eid = "ElementID"; $("'#" + eid + " option[value='" + x + "']'").attr('selected', 'selected');
I can see the raw HTML in firebug etc, but the dynamic elements (the ones created by jquery for example), obviously don't appear there. I struggle referencing some of them - Ideally I'd like to be able to trigger a display showing what handle to use for any given element - for example by clicking on them.

Here's the sitch:
I've got the a bunch of selects back from a find:
Code:
var selects = $( "#my_id").find( 'SELECT');
Now I want to say this:
For each {desired value} in array with index ix Select the {ix}th select box Set the option in the {ix}th select box whose value == {desired value} as selected
I know it's really exceptionally easy, but I suck at jQuery...
I think it looks something like one of the below two lines:
Code:
selects[ix].val( {desired value});
OR
selects[ix].val( {desired value}).attr( 'selected', true);
but I know the select[ix] syntax is wrong, and I don't know how to reference an item at a specific index from the jquery object returned by jquery.find()

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'm new to jQuery and Javascript overall, I have searched the internet to make use of jQuery instead of the HTML's iframe tag. My problem is links inside a .load file, I want them to refresh the box on the index.php file, not the file itself (in this case the links are in blog.php)
Here's everything I can provide with:
Files:
"index.php"
"blog.php"
In my index.php file I have this script to make my index.php links open the required file in my div box.
"index.php"
<script language="javascript" type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#html").load("blog.php"); // shows the blog.php when I first enter index.php, which I want to have
$(".link_click").click(function(){
$("#html").load($(this).attr("id"));
});
});
</script>
Here's "index.php" link:
<a class="link_click" id="blog.php">Blog</a>
Here's my div box in "index.php" where I show the information within the loaded file:
<div id="html"></div>
All this works, but here's my problem, I have multiple links within "blog.php" which I want to make "index.php" to refresh the "index.php"'s html div. Is there some kind of way to edit the "blog.php"'s script to make it "index.php" the parent or reference?
"blog.php"
<script type="text/javascript">
$(document).ready(function(){
$(".link_click").click(function(){
$("#html").load($(this).attr("id"));
// Need to change this(?) to make it reference the index.php's html div box
});
});
</script>
I am looking for a version of lightbox that would allow the user to click on a single reference image and when the "lightboxed" version appears a strip of thumbnails would be available at the top or bottom of that image. Thus, the user could navigate between images within the lightbox by clicking on a different thumbnail. If such beast exists a URL would appreciated. Extensive Googling hasn't turned up what I'm looking for at all.

This perhaps, because of Microsoft policy to globalize all tag names. Is there any method for cross-browser fix without using getelementbyid? Is there any method to pass values from outside of <script>, inside? (something like "global" in php functions) Javascript must be kept inside <script> tag.
