i want already select .postlike in $(this) now i want to select the tagh1 who is in .commentboxelements.i want to change the h1's inside text 1 to 2 so i write the code
$(this).closest('.posts').children('.commentboxelements center h1').html('1');
i try this but it's not worked anyway how i can do this.
I'm trying to find the trailing [code]although there is a text node after it. I suspect there may be an issue because if you get the returned [code]you get the text node containing "and some more text".

I want to be able to first grab the left position of the elements and when they like a left arrow want to take this left number value and subtract it by a number and if the the right arrow is pressed then it will add a number to the left number value.Is this possible and if so how can I do this? I am guessing i can use the .css with the .child in jquery.

I currently have a div that contains multiple divs. These divs have either the class 'labels' or 'labels-alt', I currently use the following code to change add/remove a class to one of these
function mOver1(n) {
$('.labels:nth-child('+n+')').toggleClass("labels-hover");
}
function mOut1(n) {

Let's say I want to select all the input elements of a particular form with id #form. What would be faster?
1. $("#form input")
or
2. $("input", "#form")
In my (rather unscientific) test using firebug, 2 seemed to be almost 50% faster.
I've been fiddling around with a bit of javascript in a chrome extension - something to alter the Google buzz webpage.I'm trying to find each individual post basically and have the following:
var entry =$('.X0POSb'); //This main block contains the bulk of Google buzz content
console.log(entry);
var items = entry.find('.G3.G2');

I have the following form:
HTML Code:
<form id="topics">
<p>What do you like?</p>
<p><input type="checkbox" id="cars" name="topics" value="c" /> <label
[Code]....
I want the Games checkbox to be checked when I check one (or more) of it's child checkboxes (shooter, strategy, simulation, rpg). But the Games checkbox must always remain checked when one or more of the child checkboxes are checked.What script can be used that does this and can work together with the script that is currently used?

I cant figure this out. I have an XML file that looks like this.
Code:
<?xml version="1.0" ?>
<xml>
<Root>
<event>
<image>images/eventsoon.jpg</image>
<description>Great Event</description>
</event>
[Code]....
I have the xml loaded and I can count three events xmlDoc.getElementbyTagName('event').length What I want to do is get the child elements of the event, but I cant figure it out. xmlDoc.getElementbyTagName('event')[0].childNodes[0] shouldn't this be the <image> tag of the first event? I want to pass the event as a variable and then access the child var thisEvent = xmlDoc.getElementbyTagName('event')[counter]
The problem is that I'm creating child elements based on an xml document served from a php script. However everytime it is served I'm just appending all the elements to the end of the child list creating copies. So I decided to just remove all the children each time.. But this doesn't seem to be working.
function remove_shouts(){
var shoutbox_div = document.getElementById('shouts');
var shouts = shoutbox_div.childNodes;
for(var i = 0; i < shouts.length; i++){
shoutbox_div.removeChild(shouts.item(i));
}
}
How do I selected certain child ID elements? Say for instance I wanted to select #parent #child
<div id="parent">
<div id="child">The child</div>
</div>
How can I do it with $('parent')? I tried chaining it but that didn't work.
I've looked all over and can not find what I need.
I have 6 divs this involves..
<subbody>
<covergroup>
<coverleft />
<coverright />
[Code]....
The cover group contains left & right bar images that repeat vertically as the page expands. The top is just a simple blue background (also content bg color)
Obviously content is the content of the page and both covergroup and content are within the subbody.
Is for the <subbody> tag to be the size of <content> + 5px on top (size of the <covertop>), and the left and right cover divs to expand to the size of subbody.
I guess since I'm using a footer (with image and text) letting the page expand as it wants is out, and I need javascript to make it work.
i am new at JS and jQuery and trying to make this code work. But i can't solve the problem. when u click on parent of nested list items.It hide the unordered list too. i tried to add siblings() method but still its not working like it should i.e parent of nested li should be visible to toggle its child again.

I have a form that is a regular form but in some cases it might be empty.
<form id="myform"></form>
or it might have some elements
<form id="myform"><input name="X" value="X" /><input name="Y" value="Y" /></form>
What is the proper way to count or check if the form has say inputs, select, textarea, etc..., or check if it's empty?
I have a document that contains a child frame with name/id = "help_frame".
From Javascript in the top level document I can access the child frame's
elements using:
var elem = document.frames.help_frame.document.getElementById ("chkSynonym");
but if I try:
var elem = document.frames.help_frame.document.chkSynonym;
the result is 'undefined'. What is wrong with my syntax?
so i wrote this slider with some help from an admin, everything works as I would like it to but I'm trying to make it a plugin so i need to tighten up a certain part of the code:
(function( $ ){
$.fn.jmSlider = function() {
// get total width of all li elements in the slider
var wrapWidth = 0;
[code]....
what i would like to do is instead of using "li:first" and "li:last", i would like to use first-child and last-child so the element doesn't need to be a li, in can be anything that is the direct child of the parent container.
Problem I began with: Netscape/Opera supports hover for different elements,
IE only supports hover for <a> and I want to use hover for <td class="menu">
I then found a fix using some Javascript here:
http://webpages.charter.net/mmmbeer...rbitrary-hover/
It works ok for IE now.
Problem I now have: I don't want the script to run in a browser that does
support hover for <td>.
In other words I noticed that the script was still running for Netscape and
Opera - but I would prefer to let those browser's native hover support to
work since I notice that in some cases the script can introduce lag at
loading time.
I don't want to sniff for IE: I know how unreliable browser sniffing is. I
would rather sniff for the lack of hover support.
I have a form with many fields... the fields are getting values from a
database.
I've tried onunload to just submit the form regardless of changes or
not but onunload and submit isn't working for me. Now I need some
type of event that will fire when a user tries to navigate from a page
to check to see if anything has changed and if so prompt them
(confirmation) to take action or not.
I know that the reset button only takes away anything that was added
to fields after the load so there must be some way to use the logic of
reset to simply check to see if fields have changed, right?
I was wondering if anyone has figured out a near-perfect way to check if the client has all the elements fully loaded? Not talking about all the css and text loading and the event triggers while the client is viewing images load: I mean the event auto-triggers after all the images are fully loaded, along with the css, text content, etc.
(P.S. Not talking about AJAX. Literally when somebody visits a page itself, the elements all completely load first, then the event fires.)
I have an array of list boxes. I need them to become disabled if the first one is checked (with an id of disabler_0), and I need them to be enabled if that box is unchecked. Right now it doesn't work.

I have created parent child checkboxes. When one child is selected, then parent of that child, other child of same name and parent of that same name's child will be selected... Now I want if I unchecked any child, then only same name of child and parents should be unchecked or if I unchecked Parent Child, then same name of parent and child will be unchecked.
