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 have a drag and drop box. Don't know how to solve one problem. How to check if a drag and drop box have child elements?
View 2 Replies View RelatedI'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");

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:

console.log(entry);
var items = entry.find('.G3.G2');

This seems like a relatively straight forward problem. I've searced google and these forums. I just want to select this's last child. How do I do that?

I want to be able to select the span elements that have a sub ul (ie, Grandfather,Father, but not son or daughter. I tried $('#page-ui li:has("ul") span'), which works for the top level nav that doesn't have any children, but shows up for uncle and son and daughter since it applies it to all the spans inside the first li with a sub ul. I also tried$('#page-ui li:has("ul") span:first-child'), but that didn't help either since all the spans are the first childre
I wander what gets loaded the fastest (1-2 or 3) in what succession:
<head>
<script type="text/javascript">
function andAction() {
// doing stuff
}
</script>
</head>
<body onload="andAction();">
<script type="text/javascript">andAction()</script></body>
just in the head and nothing more
This I am sure off:
<head>
<script type="text/javascript">
window.onload = function andAction() {
// doing stuff
}
</script>
</head>
<script type="text/javascript">andAction()</script></body>
just in the head and nothing more (should be 1)
Third and last which is faster:
body onload or window.onload
<!DOCTYPE html>
<html><head>
<script src="js/jquery-1.4.2.min.js"></script></head>
<body>
<table width="100%" border="1">
<thead>
</thead>
<tbody><tr><td>
<input type="checkbox" id="del[]" value="1">
</td><td>alert</td>
<td>alert</td></tr>
<tr><td>
<input type="checkbox" id="del[]" value="2">
</td><td>alert</td>
<td>alert</td></tr>
</tbody><tfoot>
</tfoot></table>
</body><script>
$('tbody > tr > td').not(children('input')).click(function(){
alert('Doesn't has an input child!');
});
</script>
</html>
I have 2 lists on a page and I have a link set up to remove an li item from the one list. I need to check to see if there is a copy of that item in the other list based off an attribute in my li item called qid. How would I look for a child list item based off this custom
attribute? Assuming I have html like the following and I want to get the one where qid=14.
<ul id="ul1">
<li qid="12" id="ul1_1">adfaf</li>
<li qid="13" id="ul1_2">adfaf</li>
<li qid="14" id="ul1_3">adfaf</li>
</ul>
I am trying to figure out the syntax for the following. For this version I am simply trying to select the 2nd child of the SLIDE HOLDER div. For this test I am just making the width grow. My next pass will be to get the index of the DOT clicked and then pass it to the child of the other parent. Please see line 24. I know this is incorrect but placed it to give you an idea of what I am trying to accomplish.
[Code]...
I try to use .not(children('input')) to selectwhich doesn't has an input child, but it doesn't work.
<!DOCTYPE html>
<html>
<head>
<script src="js/jquery-1.4.2.min.js"></script></head>
[Code]....
so i'm stuck with a little problem, but couldn't figure it out though. I have the following div
<div aria-disabled="true" class="dropwidget ui-droppable ui-state-highlight ui-droppable-disabled ui-state-disabled" title="blablabla1"> <a href="/msgpics/core/postgres-pages/img/managed43325.tmp" title="" class="preview"><img src="/msgpics/core/postgres-pages/img/managed43325.tmp?thumb" alt="" class="preview"></a> <p>managed43325.tmp<img src="img/remove.gif" class="remove"></p> </div>
and I receive the click on the remove.gif. What I want to do is to get the title attribute of the div around and write it into the <p> tag instead of the name of the file now. I've achieved several selection (yeah i'm new to jquery) but can't figure this one out.
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.
Is it possible, using client-side JavaScript, to test a series of download sites to see which is most likely to be the fastest file download site for a user?
I wondered whether JavaScript could download a portion of a file, or alternatively a small sample image file, just to test the download speed of each site, then report to the user the fastest, next fastest, and so on.
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.
[Code]....
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?
suppose I have the following:
Code HTML4Strict:
<li id="lists">
<a> ... </a>
<li>
[code]....
here it now selects all a tag in "lists" but I only want it to reference the a tag that is the direct child of "lists" li. I want it to ignore the freen highlighted part.
<li id="lists"><a> ... </a><li><a> ... </a>
<a> ... </a>
<a> ... </a></li>
</li>
I want to know how can I make it where if you right click on an element on a webpage it will select that elements id or whole html code?
View 1 Replies View RelatedI'm building a nested menu where I want to add background colors only to top menu items. I can't change the generated code, so I have to live with the id's and classes as is.Relatively new to jQuery so still not used to filtering my selections carefully—is seems to grab everything. Anyway, I have tried: .is, .content, .filter, and some parent, child stuff, but can't seem to only apply the effect to the "top" class—it just selects everything.
