I've been stumped. I'm usually good at figuring this stuff out, but I'm completely confounded here.I have a form with tables in it to add items to a series. The rows are being added dynamically by Jquery on the click event.
$('#add_hybrid').click(function(){
$('#hybrid tr:last').after('<tr><td width="15%"><?=brands('hybrid');?><input name="clubtypes[]" value="6" type="hidden" /></td><td width="25%"><?

i'm creating a ASP page, which is going to have a form in it that needs filling out. part of the form will be a table with a header row, then the next rows will have text boxes that need filling out. is there a way of putting in a dropdown box that contatins numbers that will dynamically show the rows. for example if i select 5, then five rows of text boxes will appear. if i select 14 then 14 appear.

I have some JQuery that makes an Ajax call and then adds some rows to an existing table.
function
LoadDestinationTable() {
$("#destinationTable tr:gt(0)"[code]...
The problem is that the only place where the click event fires is on the rows that were added when the page was 1st rendered – the th, for example.I also tried adding an onclick event handler to the input button’s creation – that also does not fire.

At this point I have been able to add the row. But what I want to do and am having trouble with is alternating the row colour to the dynamically added row element.
Sample of code I am using:
Code:
var tbody = document.getElementById('tableItems');
var row = document.createElement("tr");
var remainder = tbody.rows.length % 2;
if(remainder) {
row.setAttribute("class", "rowLightGreen");
}
var td1 = document.createElement("td");
td1.appendChild(document.createTextNode(qty));
td1.setAttribute("class","qty");
row.appendChild(td1);
tbody.appendChild(row);
One thing that puzzles me, is that even after adding a row the table my table.rows.length still = 0.
Does anyone know how I can determine the appropriate amount of rows so that I can apply the appropriate class?
Or is there just something blatantly wrong in my approach?

I'm trying to add the total number of costs depending on the rows added to return the subtotal then later add the service charge which gives the total grand amount.I also need to add the item number when a new row is added.

getting dynamic rows inputs to multiply 'onchange' of the value in the input in each row. It works in the first row inserted no matter what rowindex that row is moved to. All following rows only accept the initial input value and never change the 'cost' innerHTML of the colRow[i]. I figure I need a parentNode.parentNode syntax to make this function work in all rows.
Every thing is Client-side javascript and all rows are inserted to 'cartbody.insertRow[0]'. 'qtymultiply()' Function As is:
Code:
function qtymultiply(){
var cartitems=document.getElementsByClassName('itemrow');
var colRows=cartitems;

I've found a few posts on adding an event to a dynamic element, but that doesn't really help me. What I'm doing is allowing the user to add a textbox, then when a button is clicked i need to find the value for that text box, but it doesn't seem to pick up that the textbox is there.
Oh and that textbox is part of an array of textboxes, all of whose values i need.

I have a form where the users can add "name" and "id" fields by clicking on the "Add" button.
The input fields look like this (each pair is a row):
The 'name' and 'id' attributes are dynamically named with the integer increasing in value, by 1, for every new field.
As this is client controlled, I do not know how many rows there will be...

In my application I render a couple of elements dynamically after the user selects an option in a dropdown list. When the user selects another option in the dropdown, I want to remove all the previous elements that was added dynamically. I've tried with the .Remove() function, but it seems the elements cannot be found in the DOM. I've looked a lot at the .live() events.

When I add a tab, whose content is a form. The form is loaded by ajax $.ajax('url'); On ajax complete, I add a custom method for validation, which is supposed to get called when the "Upload" button in the form is clicked, but it never get called. I have searched and tried multiple things for two days now, and nothing works.

I have the following html:
<div id = "container"></div>
<div id = 'containerItemTmplt' class = "ui-widget-content">
<div class='contentHdr' onclick="test(this)" />
</div>
i then use jquery to clone 'containerItemTmplt' and add it to 'container':
var copiedElem = $('#containerItemTmplt').clone(true).
.attr('id', 'paneI1')
.appendTo('#container');
This works great and i confirm using I.E. 9's developer's tool utility that the element was indeed added with the correct id as a child of 'container'.
However in my test method, when i inspect the element that was copied, the id attribute is an empty string:
function test(elem)
{
var parentItem= $(elem).closest('div')[0];
alert(parentItem.id); //<--this displays an empty string despite
}

I am generating HTML based on user actions (in this case, populating a table with the result from AJAX calls).
In my context, I have a link where there is a Quantity field, which I would like to be editable. When I create the html, I give a unique ID to each row, (to reference to a JSON object), however I am unable to get the ID for said row, seeing as the DOM tree is parsed on the pageload and doesn't seem to update when I add elements to the page.
This means that $(this).parent('tr').attr('id') is not returning anything at all.
How would I make it so I can retrieve the ID of my row (which was created/added to the page after it was parsed)?

I am selecting an image as part of a html form. Once selected, jQuery assigns a user-defined attribute of the image to a hidden form variable and passes it to form handler. Problem is when I dynamically add images that can be selected. I am using live function to ensure that the dynamically added image is highlighted when clicked - but the user-defined attribute is not being grabbed by jQuery.
I think that when the page is first loaded, all the existing image attributes are loaded into the DOM, but when extra images are added with ajax, the DOM doesn't have the new attribute values, despite them appearing in the html on the page. I don't think I can use the live function in this instance, because an attribute is not an event. Out of ideas now. HTML/PHP, with jQuery:

I've got a database written in MySQL with a bunch of PHP interfacing with it. What I want to do is populate drop down menus on a form from this database.
The way I went around solving my problem is as follows.
Code:
Which calls the function from the search.js file, which performs the following operation:
Code:
With element2 being the appropriate preemtied dropdown box, and addOption defined as follows:
Code:
So far so good. This works and produces the correct list of elements in the first dropdown box if the first dropdown box is the target. Here is where things begin to go wrong: On this form I have an add more elements button which is defined as follows:
Code:
And addElement being defined as such:
Code:
While this does successfully create all the cells I want it to create, when I attempt to select Country from the resulting dropdown, I get an empty drop down wit only the "Search For" present in it.
Firebug then proceeds to flag array in selectorfunc above:
Code:
What i believe is going on is that for SOME reason the newly created drop downs aren't being passed js_countries correctly. Unfortunately I don't know how to fix it.

When the user select an option in a dropdownlist, new dropdownlist elements are added dynamically using jquery. When a user clicks on a new option i the first dropdown, I want all the dynamically added events to be removed so that I can render new ones. But it seems the dynamically added events haven't been added to the DOM, so they cannot be removed. Is it possible to remove them? In that case, how? I've read a lot about .Live(), but my problem is not regarding an event - I just need to reach an element(?).

I have links that, when clicked, open up a larger image. If the link has the class of "sold selected" then a semitransparent "sold" image should dynamically load as well. What I'm noticing is that it seems to appear on every other click, and I don't know why.
I've created experimental files so as not to disrupt the functioning site. [URL]
I added the variable "linkClass" on line 18; value assigned on line 53 as part of the linker.click anonymous function IF statement on lines 106-108 at bottom
I also have an alert on line 105 just to prove to myself that linkClass was appropriately setting (it is). Images 4-12 should all have the "sold" banner attached, but no matter which of those I click first, the clicking previous/next makes the banner appear/disappear.
