Jquery :: Iterate Certain Classes Over Elements
Dec 21, 2010
In my page I have pairs of divs like this:
Code HTML4Strict:
<div class="rounded red">
<p>Integer egestas neque vitae dui ultricies vel venenatis mi varius! </p>
</div>
[code]....
This works,in that it at least added the new class whereas the other solutions didn't. Unfortunately it counts EVERY div, not just the ones with the class .client, I can't set my array of desired classes, and I have no idea how to make it restart the count after it hits #4.

how I would be able to convert a string of html into a series of div elements that I can iterate through and perform jquery functions on, specifically .hide() and .slideDown(). For example, I retrieve a string from a jquery ajax call of html that looks something like this,
<div class="post" id="post2918">
<div class="header">
Some Text
</div>
[Code]....

I would like to use JQuery to iterate through a set of <div> elements that have the same class and scale each value according to a value selected from a dropdown box. For example,
<select id="factor">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
[Code].....

I have now been playing around for hours trying to figure this out. Swore I would not ask for a solution. Now I have a headache, so I am asking. On one HTML Page (From.htm) I have:
[Code]...
I somehow, need to get the values as shown in the handle function for each of Products shown in From.htm. Keep in mind the only thing I know from From.htm is the class names. I have no idea what products are listed or what the input names are. This table is generated by a third party. Assume that index.htm and From.htm are on the same website.

How do I show all items belong to classes "a" and "b"? Right now I'm trying:
Is this the right approach, or should I be doing something else?

The default behaviour for a class selector is: "An element can have multiple classes; only one of them must match." Is there a class selector where you can use multiple classes and all of them have to match?

I've got a list of links and divs. When I click on a link I want to keep showing all the divs which have a class that matches the clicked link id and hide all the divs which don't. At the same time I want to add another class (.item) to the matching divs and remove it from any div which is hidden.
When I run the code below, clicking any of the links hides all the divs apart from the one which doesn't have a matching colour class.
$('a.filterclick').click(function(){
var id = $(this).attr('id');
if($('.filterclass').hasClass(id)) {$('.filterclass').removeClass('filteredout').addClass('item');
}else

I'm putting together an events calendar athttp:[URL].. Each event is a li item, and I use jQuery to assign the class "no-left-m" (no left margin) to li:nth-child(3n+1) for CSS layout purposes. I've also added the ability to show only events in certain categories. Unfortunately, the initial jQuery assigns the classes to li items from the DOM, and doesn't take into account the show/hide. This means that when I show only a single category, the margins are off.
[Code]...
how I can assign my classes dynamically to nth-child(3n+1) of *visible* items only?

I have a jQuery script that changes the background color of odd rows in a table. If a row has class "new", though, it won't change it:
Code:
$(document).ready(function() {
$('tr[class!=new]:odd').css({'background-color':'#ddd'});
});
Is it possible to specify another class (together with "new") to which the script should not change the color? If yes, what's the syntax?

I'm trying to use a javascript class to assign specific event handlers to different elements. I create an object and pass it a reference to the element, and some properties for the event handler to use. When the event fires, I want the handler to reference the properties of the object. But I'm clearly doing something wrong as multiple instances all refer to the most recent object only.

I'm trying to iterate through all the dropdownboxes on a page without much success! What I'd like to do is store the selected value for each of the dropdowns, separated by commas in a variable when a button is clicked. Each of the dropdown boxes 'id' begins with the string 'attrib-' which is how I'm trying to identify them.
I've managed to hide all the dropdowns with this code:
jQuery(document).ready(function() {
jQuery("#myButton").click(function() {
jQuery("[id^=attrib-]").hide();
})
})
So I thought I could do something similar to get the selected value but I can't figure it out.

I have a form on which I've created 5 checkbox groups. Each of these groups consist of multiple checkboxes. The first group - it's id equals "MASTER" - contains 4 checkboxes. These checkboxes are labelled (that is, their actual label tags are) "A", "B", "C", "D". My vision is to have a user check, say, "A" in MASTER and this causes the "A" checkbox group to appear below the MASTER group. If a user then checks "B" in MASTER, then the "B" group appears below the "A" group. If the user then unchecks "A", then the "A" group disappears. And similarly for each of the four "subordinate" groups. My plan of attack was to iterate over the MASTER checkbox group, and for each checked box, somehow populate an array of their associated label tags. I would do the same for all of the checkboxes in MASTER that are not checked, placing their label tags in another array. I would then show and hide the subordinate checkbox groups based on these label tags. The subordinate groups have label tags equal to these captured label tags in these two arrays. All of this action would be triggered via a "click" action on the tag in which the MASTER group resides. I've tried all manner of techniques, including "$.each" and ".map" to populate arrays. I just can't get my mind around the needed syntax.

$('#navbutton-' + i).click(function(){
updateStage(i);

As soon as the page loads, I would like to iterate through several span tags on the page and update their innerHTML to be the response from the AJAX get call. The line I have commented out, alert("Data Loaded: " + data);, works perfectly, but creates a bunch of alert boxes (which I don't want). And if I move the line "this.innerHTML =data;" out of the Ajax call, it works fine also. So I know all the syntax is correct. But when I put it together as outlined below, it just won't work. The Ajax is working, I also see the GET calls working fine in the Firebug console. It just won't update the innerHTML of the SPAN tags.

I cant get this each function to work inside a form: For example I have this code:
$('#formid>input').each(function(){
if($(this).attr('id')!='') alert($(this).attr('value'); //fetch id if
not blank ang show value
});
The code inside this function does not run if the form is rendered this way:
<form><div id='tabs" >
<ul>...</ul><div id='tab1">
<input type='text' id='fname' /></div>
</div></form>
But if it is rendered in a simplier way like this, it works:
<form><input type='text' id='fname' /></form>
I am using jquery jquery-ui-1.7.2.custom.main.js library by the way for the tabs but I don't think that messes up the whole thing though...

I am very new to JavaScript / JQuery... Need to iterate over the following segment of code and either return an array or single value the e-mail addresses assigned to these labels (these are hardcoded as the check boxes values):
<div id="emailCheckListId" class="checkList">
<ul id="emailCheckListId_ul">
<li>
<label for="root.module.emailCheckList_0" class="checkListLabel">
<input type="checkbox" value="johndoe@aol.com" id="root.module.emailCheckList_0" name="root.module.emailCheckList"/>

I'm trying to interate through an array of objects. Here's my code:
$('form').submit(function(){
var serializeArr = $(this).serializeArray();
jQuery.each(serializeArr, function(i, obj){
alert('Hi');
}
});
However, this just fails. It seems like its getting stuck on the serializeArray aka an array of objects. I've gone the for loop route and it worked fine up until I started doing some ajax stuff...the variable binding behavior was all over the place and unusable.

I know that using for in loop to iterate over array elements is a bad
idea but I have a situation where it is tempting me to use it. I have
a two dimensional sparse array say "arr" which will have length to be
some 50 but will have some elements like arr[1], arr[10], arr[23] at
random locations. Each of these elements is again an array (since it
is two dimensional) say arr[1][30], arr[1][24] & so on for arr[10 &
23] also. Currently I've coded it like this:
for (var i = 0; i < arr.length; i++) {
for (var j = 0; j < arr[i].length; j++) {
if (arr[i] && arr[i][j]) {
// do stuff with arr[i][j]
}
}
}
but i am tempted to do following
for (var i in arr) {
if (!arr.hasOwnProperty(i)) {
continue;
}
for (var j in arr[i]) {
if (arr[i].hasOwnProperty(j)) {
// do stuff with arr[i][j]
}
}
}
thinking it to be faster. What are your views?

In this program i attempting to iterate through an array using the charAt () function and then store these element positions in a new array called elementPositions.
The user selects a flightDestination from the flightDestinations array which is stored elsewhere, and what my program needs to do, is find all the array elements positions where the same flight destination name occurs in my array.
I then need to store these positions so i can use them elsewhere, and i'm pretty sure i need to use charAt() but i think my syntax may be wrong - contained in the for loop.
var yourDestination = readTheDestination();
var title = "<B>" + "You asked about Flights to " + "<B>" + "<BR>";
var flightInfo;
var solution = "";

Is it possible to iterate through an anonymous array of strings with a for loop?
Here's what I'm trying to do:
for ( i in ['country', 'city', 'state'] ) {
doSomethingWithString(i);
}
What I want is the string, but what I'm getting is the index number of the array, which I can't use because the array isn't named.

I have a problem in Javascript that I really cant figure out, I've tried for days! here it goes: I need to iterate through a form and get all the elements that has a class like "required" and then, save this elements id, because I have label elements that has a for="" tag with the same as the id for the input/dropdown in the form. To all these labels I need to apply a "*" in the end of the label. And all this in an onload function.
I have tried everything I can come up with but now I'm close to giving up so now I need help, how can I get these values and do this?

Is it possible to iterate over user-defined objects in Internet Explorer? Iterating over objects in top in Firefox (v 3.5) finds user-defined objects, but it does not in Internet Explorer (v 7).
Code:
function myFunc() {}
for(var obj in top) { alert('objname=' + obj); }
In FF the above will find myFunc, and in Internet Explorer it will not. Should I be checking a different scope?
