View 2 RepliesI am new to this discussion but hope you would post reply for my query and encourage me to keep in touch with this discussion. Well here is my problem. I have made an edit in place form in which we can add and remove the elements. I have used jquery.jeditable.mini.js and jquery.duplicate-remove.js plugins for edit in place and add and remove action. I have live() function to access the dynamically ganerated elements like this. $(".addressDiv span").live("mouseover", function(){
clickable function here...
[Code]...
I just dont know the right syntax for this:
I want to change the css class of the li element from the name hidden to the variable filterVal, but i dont know the right syntax.
Way I can get at a single class when many are defined? [code]...
The script above doesn't work because the class has multiple definitions i.e.
class="tags current"
Is there a way to easily find a single class out of many?
In my effort as a javascript newbie i'm trying to create a nothing too special progress bar. I'm this far that the li's (bars) get a different color after another, but in the end it needs to change all bars back to the original class and start over. How do I accomplish this?

I'm trying to create a new validation rule to check if a button has a class. I try to explain the scenario. I have a button that makes an ajax call to check the availability of a product. When the app loads the button as class "to_check", when the button is clicked an ajax call is fired, a server script return the availability of the product and basing on this answer I change the class of the button from "to_check" to "ok" or "ko". Now I want to validate the button to se if the availability is being checked and is ok, then I wrote this:
<pre>$.validator.addMethod('hasClass', function(value, element) { if($(element).hasClass(value)) {
return true;
} else {
return false
}},
jQuery.format('Please check the button'));</pre>
Now I want to add this rule to the button with the metadata plugin inside the class name with this syntax:
<pre id="line175"><span id="__firefox-tidy-id"
style="background-color: rgb(221, 221, 255);"><<span
class="start-tag">input</span><span class="attribute-name"> type</span>=<span
class="attribute-value">"button" </span><span class="attribute-name">name</span>=<span
class="attribute-value">"verifica_disponibilita" </span><span
class="attribute-name"> .....
I'm running validation on a form that has two components, a payments segment and an address segment. Both of these need to be within the same form. By default, the address segment is hidden. Upon validation, I would like to display the payment segment, but only if there are validation errors within that segment. Using invalidHandler, I've been able to successfully fire a function when errors are returned, but I haven't found a way to check if there are errors within that container. My plan was to check for the invalid class within that container... something like this:
$(#formname).validate({
invalidHandler : function() {
if ($('.client_validation').length)
$('.billingAddress').addClass('showForm');
}}});
The problem is that the invalid class (.client_validation) isn't applied when the invalidHandler function is executed.
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.

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 am trying to access an element in a page using ID using jquery in when the document is ready.But the problem is the length is always 0 even if the script tag is in the head or right at the bottom of the page. The element is seen rendered when I see it using FireBug.an someone point out where I am making a mistake accessing the element
$(document).ready(function() {
alert('Hello World");
$('#id').live("click", function() {
[code]....
I have the following markup:
<div class="Field">
<label for="City">City</label>
<input type="text" id="City" name="City" value="">
<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?
This is what I have:
function ShowHide(){
$("#navigation_sub").animate({"width": "toggle"}, { duration: 500 });
}
[code]....
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 need to select a class within an element. the class is generated by the code using .addClass. I suspect this is actually really easy and I'm just being stupid,

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>

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?
