JQuery :: Difference Between Class Selector And ID Selector?
Sep 8, 2011Are there any difference between class selector and ID selector
View 2 RepliesAre there any difference between class selector and ID selector
View 2 RepliesI have a huge blob of code but the main part I am focusing on is this
$('.billboard_click').click(function () {
//this remove class
$(".billboard_click").removeClass("billboard_click");
});
1. Execute a click event when the div with the class 'billboard_click' is clicked
2. Once clicked, remove the class from that very div to avoid another click from happening
3. Execute a series of events such as animations, etc
4. add the class back to the clicker div
The code does not seem to work as expected but I am wondering if I am having issues elsewhere at this point and wonder if this actually is known to work
I'm trying to figure out which selector is faster (assuming that the class 'foo' only appears on input tags)...
$('.foo');
or
$('input.foo');
From what I've seen online, it seems that people recommend $('input.foo'), but in some limited testing it appears that $('.foo') is much faster in both FF and Chrome. In IE, both methods seem to produce similar results. Here is a fiddle with a simple example...

Have browsers started implementing native ways to find all elements with a given class name? Would that explain why $('.foo') seems to be faster?
[URL] The above webpage lists the selector .class.class without an example. I can't find this usage in jQuery document either. I made the following example, but it doesn't work. Could anybody let me know who to use the .class.class selector?

I am trying to make a sliding panel if you click a button, the only problem is that there are more of this panels on the page. I can make the first one open, but I cant make the one opening wich has the id=id.

I have used sophisticated selectors in the past but for some reason am brain-tied right now.I have a clickable div followed by another div (a sibling. not a child) that will reveal when clicked.
of course it works when hardcoding the second div as the target but I want to make it reusable so that it looks for the next div matching that class selector

I've take an example from the docomentation and changed the names. I allready have written some nice functions

I am unfortunately having some problems with JQuery of late. I am working on a project in which I need to have an AJAX application working in all major browsers, including IE6 and IE7. I have created a click event for a button of the class "update" and "delete" in which an ajax request will be sent to the server. Unfortunately in IE6 (and only IE6) the event will not fire. After much experimentation I realized that it was the class selector.
Here are some code tests I have been doing to get a click event to fire:
Do you have any ideas as to why none of these work?
$(".mainmenu-topcontainer > ul > li:not(:has('.stateselected'))").hover(function(e){ (...)
I tried it with and without quotes. Do I miss anything? That selector matches all Li elements.
The following code worked fine in 1.2.6 but after upgrading to 1.3.2 only the first table cell is shown/hidden.
<table>
<tr>
<td class="more">a</td>
<td class="more">b</td>
[Code].....
Version 1.2.6 used to add style="display: none;" when hiding, and would remove it when showing. Version 1.3.2 adds toggles between style="display: none;" and style="display: table-cell;". I don't think that matters really, what does matter however is that if I alert jQuery('.more').length I get 1 not 4.
I have a problems with selectors. I have the following HTML code:
<div
id
=
"myDatepicker1"
[Code]....
But the alert message does never appear and I did not get JavaScript errors. It seems that the selector does not match and so the alert message and the .hide() does not take effect.
I am a newbie here and had a strange problem, maybe someone can explain it: I have a function that changes it's element class on click. I Also use the class as selector for that function. So, when clicked, it should not be clickable again. But it does, like if, even after removed, it's class would still remain in the memory of DOM, or something.

What is the syntax for accessing the children of a class, where the class is a variable?The html structure is multiple divs like this:
<div class="class1 class2 class3">
<p class="x"> lorem</p>
<p class="y"> ipsum</p>
<p class="z"> yadda</p>
</div>
(There's a structural reason for accessing the child <p> tags, rather than just the parent <div>s. Some <p> tags in some<div>swill have previously had a style change applied: if the changes are now applied only to the parents, some children won't changeā¦ at least not till they're hidden).Anyway: this code doesn't work, doesn't generate a FF error message, and doesn't stop subsequent chained functions from operating. So it can't be far off; and the syntax$(cl + ' > p') works ok in another function.
I'm trying to find an example of a country selector (which also provides a state selector if USA is chosen) then you cvan select the city, any samples out there?

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');

1. I want to have 2 things on my page: an unordered list of links at left, and a grid of images at right. Each item in the list is represented by an image in the grid. This is how it should work: when you mouse over an image, the text link at left changes color. So, I hardly know any jQuery, but I suspect that you need to dynamically insert a css class selector into the <li> for that list item. How in the world do I do this?
2. I am using this plugin: jQuery cycle lite. Is there a way to make the images appear in random order, rather than in the same, fixed order?
The DOM looks like this. I need to get all hidden inputs that have siblings with class of myClass. So in this example I would like to get the first and third hidden inputs back.
<div>
<input type=hidden>
<label>
<label class=myClass>
<label>
</div>

I'm having trouble getting a selector working. Probably best just to give you some example code:
HTML
<input type='button' class='test' value='Button Name'>
<div>
<a href='' class='buttonLink' />Click me</a>
</div>
Jquery
$(.buttonLink).click(function() { $(this).closest(':button.test').addClass('testclass'); });
Form that code I would expect the class of 'testclass' to be applied to the button after the link is clicked, but It doesn't seem to work. This is a somewhat contrived example. In my real application I have a form with several collapsable/expandable sections. If the fields in those form sections have values when the page loads, the section needs to be expanded, and the expand/collapse button needs to have a class of 'expaned' applied to it, if not it needs to be hidden. I can check the form fields and show the div if needed without any problem, but I can't seem to figure out how to work out the selector so I can add the class to the button.
I'm trying to create a drop down menu which has several levels. When a level is clicked on, other expanded categories in that level should minimize simultaneously. The trouble I'm having is using a combination of selectors to say 'all divs which match this pattern but not this one'. I've had a look through the selectors API pages
View 1 Replies View Relatedi use it in a CMS. In my content page, when I insert a floating element, I use it to set the margin around element according to left or right float in this way:
$('#content img[style*="float:left"]).css({
'clear' : 'left',

I have a problem that I couldn't solve myself. I have 2 forms. name="form1" and name="form2" In each form, there's the same class names for rows. <tr class="draggable">
What I need to do, is to take the last draggable row in a certain form. $( tr_object + " tr.draggable:last" ) <- returns the last tr with class draggable in whole document. How do I limit It's view/search scope to one of the forms only?
var string = $('#newItemInput2').val(); // gives me "twats"
But when I try and embed it within an object it doesn't work:
Can a jquery selector not be used as the member of an object?
this code works for me , but there is something wrong , every time the function loads (every 2.5 seconds )the html is loaded in row [0] cell[0] , and they are stacked above each other . what may be wrong there ?
code :
var searchtable=document.getElementById("searchtable")
var resultscount=0

I am using the contains selector for one element because I do not know the full ID. Since I only need the first element it finds should I be adding something to improve performance?
