JQuery :: Change Class Of The Mother Tr Element
Jul 5, 2011
The competition is that there is a table width a heckbox inside and if the ckeckbox is checked the tr of this checkbox should get class "sel" and remove this class if it get unchecked. So the problem with the actual code is that everytime a new checkbox got checked the <tr> of the checkbox which was checked before losts the class "sel" and just the last checked checkbox will get it. Do you have an idea how the could must look like to get it work?
Html like this:
<table>
<tr><td><input type=”checkbox” class=”cbU”></td></tr>
<tr><td><input type=”checkbox” class=”cbU”></td></tr>
<tr><td><input type=”checkbox” class=”cbU”></td></tr>
<tr><td><input type=”checkbox” class=”cbU”></td></tr>
[Code]....
Even if the else will be deleted the problem is stil there so the failure must be in my code.

I have some legacy code that creates an image carousel and outputs AFTER the document head has been output - the CSS for this was being aded to a style block within the <body> which although worked is not compliant. I am trying to use jquery to set the css, but one part if failing. This is the original css :
#div_tab_one a:hover { .... }
#dic_tab_one .selected a {...}
How can I inject this css ? the selected class is set by some YUI code and rotates through the carousel setting/unsetting the "selected" class.

I am trying to change to change the background of a li element when its own class is changing
i tried :
$("ul#slide-nav li").each(function() {
if ( $(this).hasClass("selected") ){
$(this).css("background-color","black");
}else{
$(this).css("background-color","gray");
}});
This seems to be working I think., but once the class change again it doesn't work.. how can it loop for ever?

What options do I need to specify for the Validation plugin to simply add the error class to a specified element such as a "required" em that shows all the time. And so on to remove the class when valid.
Say we have a text input that I want to have a red border when not valid and the red border to disappear once valid. So I do not want to generate an error label.

I'm trying to find a way to change the CSS class for all my many input type elements with an onclick. Is this possible? The scenario I'm trying to fit it into is below (and condensed).
Ideally I'm looking to change the style for background-color onclick, black and white in particular (hoping that the solution would mean adding more colours later).

I have a question here, I have a mother page of 2 divs, one for the category list of foods on the left and the right div is a placeholder for the selected food of the category,
Then i have a modal box, which loads the list of foods associated to the category when clicked,
What i wanted to do is, when i select a food from the modal box and click submit, I wanted to populate the selected food into the right div of the mother page, so far the farthest i went is loading the list of food into the modal window,
its like a shopping cart, but instead of redirecting your users to another page, you display all their orders on the same page... can this be achieve, im using jquery+php sessions

Yeah I know another frames question why don't you use tables but hey.. They wanted it this way..
Any how.. I want a javascript that just checks if the "mother" page is set.. so for instance if I were to call page.php directly that it would check if the complete page is loaded and if not that it would load the complete site (index.php) and the pass the variable pagename for instance in the url thats fine but just that it would refresh the window also loading the nav. frame

I'm doing a very simple expand/collapse function using 'slideToggle'. The button that triggers this event simply says 'Expand/collapse'. I want this text to change depending on whether an element is visible or hidden.

I'm relatively experienced with jQuery (not a guru but not a newbie) but am wondering how I can write a script where if one element is hovered over then a different element on the page has a particular class added to it.

I need to add class zebra to the <li> elements with the content next to them.This is as far as I've got, but I'm not sure what calculation to use:
$("li").each(function(index){
if(index % ??? == 0) { // <-- not sure what to put here
}
});

hi everybody, didn't find this using the search :( this is my problem:
i create a dom element dynamically (<span>) and want to assign a class
attribute to it such that it has some css style, this works in ie, but
not in firefox :( here's the simple code:
<div id="somediv"></div>
var div = window.document.getElementById("somediv");
var span = window.document.createElement("span");
span.innerHTML = "span";
span.attributes.getNamedItem("class").nodeValue = "span_class";
div.appendChild(span);
so this works well in ie6, but firefox gives this error:
Error: span.attributes.getNamedItem("class") has no properties
if i run this code on a statically defined span (in the html file),
where a class attribute already is set:
<div id="somediv">
<span id="spanspan" class="">
</span>
</div>
changing the class to "span_class" works both in ie and firefox.
how can i fix my above code such that it works in both browsers? it
seems that on newly created dom elements the class attribute isn't even
there (to change it), how can i create it, and then change it?

I have the following markup:
<div class="Field">
<label for="City">City</label>

<ul>
[Code]....
not sure if this is the best way. Can I improve it?
However I am having problems in adding (2).
Basically I think I need:
$(this).closest("div.Field"). Label or span.Label that are not inside LI.addClass("Hover")

This is probably a dumb question (noob) but I cannot seem to find the answer, either here or on StackOverflow or even Googling...
All I want to do is, when clicking on an element, find any other elements with the same class name (and show/hide or do something with them).[code]...
But I need the class name to be a variable so this function is reusable.
What am I doing wrong?

I have a bunch of elements with multiple classes like this:
<div class="foo bar">
<div class="foo bar snafu">
<div class="foo bar">
I can get all these elements in an array like this:
$ (".foo,.bar")
My question is - is there an elegant way of getting the index (in this array) of the element that has the "snafu" class? Or should I just iterate through the array until I find the wanted element and then remember its index?

Is there a non-structure specific way of finding the next element with a given class? for example you have a structure of:
When you click on the link in container1 the expected behavior is to change the css on a1 in container2 but not in container1 or container3. I have tried playing with parent, next and filter without success. this is the best I have is:

I have table that has four columns and many many rows. It is quite long. I need to add a special divider (border) between each td cell. I thought I could create a css style .border_right and apply it to all td cells using jquery addClass() and then remove the class from the fourth td cell in each row so it does not add to or affect the outside border of the table.
My question is, how do I remove the class from the fourth td of each row using jQuery? I figure there has to be a shortcut way (one or two lines) to do this using jQuery so I don't have to manually add a 'class="border-right"' to each td I need it on.

I have a div with several classes on, like this:
<div class="class-one class-two special-class"></div>
I want to get the class that starts with 'special' and store it in a variable...but I am having trouble doing this...I can get as far as storing all of the classes in a variable:
var myClasses = $(this).attr('class');
...but I now need to extract just the one class that starts with 'special'...
