JQuery :: How To Get Width Of Children Of DIV

Dec 16, 2010

I have a div containing many children all very different, each one as a different width. I need to get the width of all the children. I mean child1.width() + child2.width() + child3.width() etc... Of course as a new child can be added anytime I can not use the kind of things I put above.

I tried that among other things :
$("div.mydiv").children().width();
But I only get the width ofthe first child.

JQuery :: All Images Must Be Resized If Width Exceeds Max Width?

May 5, 2010

I currently have a website where i share thoughts with my friends (some kind of forum) and within this 'forum' people can post pictures they made but most of the time these pictures exceed the max width of my website so my website gets all streched out!So this is what i want: all images on the page must run thru some sort of function which checks if the image image width exceeds the max_width. if it does then the script must calculate how many pixels the current width exceeds the max_width and get this number so that the script does: current_width = current_width - (max_width - current_width)

JQuery :: Resizing Width Depending On $(window).width?

May 18, 2010

I've recently start using Flexigrid (old JQuery grid plugin), and, as you may know, one of the few issue this really good grid plugin got is the lack of liquid layout option. My personal idea to solve the problem is to set the "width" parameter depending on $(window).width. Here is the problem (and here's why i post this question in "General use" and not in "Plugin").

The starting, and working, code is:
$(document).ready(function(){
$("#flex1").flexigrid
(
{

[Code].....

This work fine for me, but I supose it could be done way much elegant... maybe somethin without "IF" that could emulate the "%", like var percentage = $(#div.id).width()*0.XX with the 0.XX picked from an array of percentage, one for each column. Probably I should set up a function... ahhhh, as you may easily see I'm a total beginner with JQuery (and JS in general...)

Defining Div Width Equal To Undefined Amount Of Images Total Width?

Oct 4, 2010

let me try to explain better what I'm trying to do. I'm a real newbie I don't know much javascript but I understand more or less the logic behind it... tell me if this solution should work and if you know how to do it please show me. [URL]... I need to make div#photo's width to match the total width measurement of all the images it contains. If you load the page and you don't touch the size, it will work fine... but that's not realistic. If I resize the page, which will happen often on this kind of page (I'm assuming), the whole thing goes haywire (try it, scroll to the last image and resize the page you'll see what I mean). What can I do? Is my idea the right solution? Am I not explaining this clearly enough? Let me know please, I'm desperate. I've been trying to get CSS to do this for me for 3 hours now. Nothing works.

Set Width Of Item Based Off Combined Width Of Other Elements?

Jun 4, 2011

I am trying to setup a javascript function that sets a div's width based on the combined width of the li's with the name "navItem". The problems I have been running into when trying to define the width of the li's is that they do not have a width defined in css. Can anyone help me out with this? The javascript function setWindow is suppose to show the div loginWindow and set the width of it.

Code:
<div id="topNav">
<ul>
<li><img src="<?php print $site->folder['images']['header']; ?>topmenu_left.jpg" border="0" alt="" /></li>
<li name="navItem"><a href="<? print $site->url['about']; ?>">About Us</a></li>
<li name="navItem"><a onmouseover="setWindow('loginWindow');" href="<? print $site->url['billing']; ?>">Client Services</a></li>

[Code]...

JQuery :: Select A Tags With No Ul > Li >a Children?

Oct 7, 2010

I have about 13 ul li a items in a list and some have nested lists within them e.g. ul li ul li a and some don't. I want to prevent the default action on only a elements that have nested lists within them but not prevent default action for ones that don't. Here's an example of the markup.

[Code]...

However, instead, is there a way to tell jQuery to only apply this preventDefault to ul li a elements that have ul li a descendants/children (not sure of correct terminology here) so I can have the list items in any order?

JQuery :: :contains Selector To NOT Search In Children?

Nov 26, 2010

just wondering if there is any way for the :contains to not look in children to find something? Tried $(':contains("$")');, but it returns everything. Was thinking of something like $(":not(':parent')").filter(':contains("$")');, but the console returns null (and even then it would exclude elements that have children and their text includes "$".)

Trying to make a script that looks through a page and finds the price on any page. The only way I could think of doing this relatively accurately is to search for all elements with "$" in the text, then get the one that has the largest height/width (That's problem #2, I think -- will deal with it once i get there :)

JQuery :: Selecting First Level Children Only

Feb 13, 2010

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 :: Selecting Immediate Children Only In Object

Feb 12, 2010

Taking 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> .....

How can I grab the immediate li children only and not all of the li that fall in this object. The following gives me every single <li> which is not what I am looking for.
(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);
});
}});

Nov 27, 2009

I'm a beginner at using jQuery for website interaction and I needed to create a simple sidebar menu. Here is the HTML code:

[Code]...

It basically works, but only if I remove the code part where I first hide the children of the sidenav, but doesn't work when I want at default all children of the sidenav to be hidden and showed only if clicked a particular parent menu. 1. How can this be accomplished? 2. Also how can I hide the children of previous clicked parents when I click on another parent to chow it's children?

Jquery :: Deleting Last X Rows (Children Of DIV Fields)

May 8, 2009

I have the following html and I'm trying to figure out how to delete the last rows the are children of div feed. I only want to leave a max of the first x rows. First I count them using $numdivs = $("#feed > div").size() - 1;.

JQuery :: Get ID's Of Children Div's Of A Class With A Specific Parent Div ID?

Mar 8, 2011

I'm building a volunteer translation site. In order to constantly update only paragraphs that multiple translators are working on, I need to pass an array to PHP of A: which paragraphs are open, and B: which translations have been submitted and are visible on the user's screen. PHP will then compare this with what is in the database and tell jQuery to add new submitted translation paragraphs or remove deleted ones.I've managed to make a string of all the open Div's and have it updated every second, like this:

function cycle(){
var data = '';
$('.paragraphtobetranslated:visible').each(function(){

JQuery :: Select The Last Children Of Parent Elements?

May 3, 2010

I need to select the last children of parent elements

For example


<ul>
<li></li> <-This will have the background #1a
<li></li> <-This will have the background #1a
<li><ul>

[Code]....

So I would need the last children. If there is no nested element then that is considered the last child. I have to write a jquery script to apply a background to the last children. A nested element can have a nested element and then that element's children will be considered the last ones so they will get the background but not the parents of those children. If the item has no children then that item will have a background.

So there are 3 different backgrounds. Each letter a, b c will represent a lighter tone compared to the previous color. C is lighter than B, B is lighter than A etc. So this will have to be a "smart" system in which the ul li will be updated and depending if it is the last one inhierarchyit will not have the arrow.

JQuery :: Hide A Nested UL But Show Children?

Oct 30, 2009

I have a set of nested ULs that is generated for me. I want to use it to create a drop-down navigation menu, however I don't want to use the values in the second level of ULs in the navigation. It looks something like this:

<ul class="topMenu">
<li>home</li>
<li>community

[code]....

Level one is visible as sort of tabs, and then mousing over should reveal a list of the next level of links.I would like to use the above list and mouse over "community" and see a list of links

award type 1
award type 2
discussion 1

[code]....

Or another option would be to combine levels 2 and 3 so I would see

awards
award type 1
award type 2
discussions
discussion1

and then mousing over discussion 1 would reveal the more info link.

JQuery :: Hiding Children Menu On Hover

Jun 23, 2009

I got this here: [URL]. When you hover over the Buy Rhoadanide or Research the sub menu comes up. The only way I could get it to work was to make the OTHER menu hide if one is hovered over, but I cant hide them anymore
Is there a way to do this:
1. Hover Link
2. Show Div with more links below it
3. Keep the Divs visible if the Hover Link or the Div is hovered
4. Hide the Divs when both are not selected.

JQuery :: Listen For Change In An Element's Children

Sep 13, 2010

I have a UL that loads in dynamically after the DOM has already finished loading via and external API that doesn't have a callback function for when it's finished. However, I need to manipulate the children of the UL once it's loaded in, so I need some type of listener for when the UL changes.I need an event to fire when an element or it's children change.Is there anything like this in jQuery? Otherwise I'm going to have to create a setInterval to polloccasionallyto see if the UL has loaded, and that sounds sloppy.
