JQuery :: Select Top Level Of Nested Structure?
Jun 11, 2009
Given the following structure:
<div id="section_list">
<ul>
<li></li>
<li>
[Code].....
Not only does it look hacky, but it's giving me obviously bad results. To complicate things further, I'm using MPTT for my tree data, so sortable's serialize isn't much help, unfortunately. I originally thought I might figure out the parent_id, lft, and rght values upon sort but that would entail storing all that data somewhere in the DOM. I then realized that, if I can just get the number of positions moved, I could update the DB with that information.

How do I return false (or true) from within a nested control structure.For example, I'm using jquery and I would like to do some basic validation:I want to pass to a custom function named checkDefault every element with the class required.
function checkDefault(elem) {
elem.each(function(){
if(elem.val() == elem.attr('title')) return false;
[code].....

I am trying to select (and then clone) an entire DOM structure excluding one div.
The DOM is stored in a variable like this: var original = $(this).closest("table.mainContainer");
The I try to exclude the div in the clone like this $(original).find(":not(div.container)").clone();
But the div is shows in the clone.

I am working on creating a 2 Level Interdependent Select List and I am using javascriptkit.com's code they provided.
HTML Code:
Which is working to they way they said it would. I am trying to make a modification to it to which I have on idea where to start as i know very little javascript.
Basically what I want to do is delete the <option selected>Select A City</option> from the first select field and make it where when you first see the field it displays the USA option.
Since the USA option will be the on that is showing when you enter the page I don't want second select field to be blank but instead show the cities of the USA. Then if they choose to select on Canada it would delete the USA cities and just show the canadian cities like it is already doing.

I am trying to turn a single level flyout menu into a multi level one.
It uses a dt for the title, and a ul within the dd for the menu items. The dd opens to the right of the dt.
The problem is that the second level menu (a dl within an li within another dl) [URL] - flyout4 & subflyout5.
The z-index is increased each time. I just can't figure why the area is limited.
javascript, css & html follow -
Code JavaScript:
/** FLYOUT = vertical dropdown **/
var Flyout = {
DDSPEED:10,
[Code].....

I am trying to get a java script function that will return the start and end position of a selection and the selection content.
I tried this code I found here (modified a bit)
Javascript text
And it works nearly perfect. As the comments indicate, however, it won't work with any nested elements without some "additional coding". I am just learning JavaScript, so I am ok with the basics. But the DOM tree has me baffled, and I can tell that this is the section of the code that would need to be modified.
So, my question to those that actually know what they are doing, is how do I modify the above script to allow several span nodes nested within one parent div, or is there another source for a code that might get me there?
I did a ton of searching for one, but every one I found was related to selecting within a text area, and I need to select within a parent div.

I have a JSON data structure that I'm pulling in VIA an AJAX call. What I want to be able to do is click a button/link and be able to save this data structure to disk, but I'm not really sure how to go about this. I've been experimenting with the following:The link has the following format "<a href='data:application/json, " + data_structure + "'>Click here!</a>" I've been able to replace data_structure with text and /json to /rtf, which gives me a pop-up 'SaveAs' dialog box, and when I open the file, it has my text in there. However, if I do data_structure, I just get [Objectobject], which is telling me that I'm passing in the object, but that's basically it, I need to expand it out? I'm not really sure how to do that...Which leads me to calling a perl script. So I make an ajax call like so:
$.ajax({
'dataType': 'JSON',
'type': 'GET',
[code]....

I'm trying to come up with a better architecture for dealing with multiple listeners in a multi-page questionnaire. Here's the general structure I'm looking to implement:
1. Set up CSS for animation
2. Look for preconditions
3. Initialize listener
4. Execute animation
Some issues to consider:
1. Some questions have dependencies that show or hide depending on what is selected in a parent question.
2. Needs to be IE 6 compatible.
3. It should be simple enough so that all you need to do is add a new question to a JSON object, which is what I have set up right now.
Some code (the looping structure that reads each question):
var newQ = eval(q);
$.each(newQ, function () {
// 1 - Setting CSS for each listener
$(this.css).css({'width': '1500px', 'float': 'left', 'clear':'both'});
[Code].....
The problem here is that when I do a console.dir on $.each(this.value.length), it counts each character, as opposed to counting the number of elements in the array. Should I be doing an eval on q? Why or why not? If I could get this up and running, it would make my life 100x easier, as there are hundreds of questions, and I'd want to make this all data driven.

I want to accomplish a nice and simple accordion menu using this HTML structure:
Code HTML4Strict:
And I'm using this JQuery code:
Code JavaScript:
This basically works, but when I click a particular menu item to expand it's submenu items, it basically hides all submenus items, even the active ones, but whant I need is the particular clicked submenu items to stay expanded. I guess this can be accomplished by a simple if statement or so.

I've seen a variety of implementations around that enable selecting all or no checkboxes by using a checkbox to toggle that choice. However, I'm trying to find a way like this: I have two text links on my page: Select All, and Select None. How can I get those links to call a jquery function to select all or select no checkboxes in my form? As a little food for thought:
<head>
$(function() {
//function for selecting all or none...is there a way to make a single function that passes in a parameter to differentiate between selecting all or selecting none, or do I need a separate function for both?[code]....

Given the following markup
<div id="menu">
<ul>
<li><a id="home" href="#">Home</a></li>
<li>
<a id="about" href="#">About</a>
<div>
About sub menu
</div></li><li>
<a id="products" href="#">Products</a>
<div><h2>Books</h2>
<ul><li>ColdFusion</li>
<li>jQuery</li>
<li>CSS</li>
<li>HTML</li>
<li>Groovy</li>
<li>Hibernate</li> .....
How can I grab only the 1st level children of my node? I want direct decendents of menu only. My code below is grabbing all <li> which is going to be a problem.
(function($){
$.fn.extend({
myplugin: function(options){
return this.each(function(){
// the object we are working with
var obj = $(this);
// get a list of menu items
var menuItems = $('li',obj);
});
}});
})(jQuery);
