JQuery :: Add & Remove List Elements?
Jun 28, 2011
I'm trying to allow users to add the text from a text input into a list, and then have the option of removing this list item. So far I have the code below which allows me to add a styled list item with a link in it which I would like to close the box when clicked but at the moment when I click it nothing is happening. I'm not sure if I'm approaching it correctly or if there is an error in my code.
jQuery(function(){
$('#addTask').click(function() {
var Task = $("#jobTasks").val();
if (Task == '') {
[Code].....

I have a page I am working and I am having some trouble with: I need to show and hide areas based on a radio selection. I initally started using the show / hide feature in Jquery but the problem is the elements need to be removed but then put back if the user selects the radio buttonagain as it has form elements that have validaion on them. The validation is still trying to validate the form elements becuase they are still on the page but just not showing. This is the radio group the user makes the selection from:
<input name="terms_usr" type="radio" id="terms_usr_1" value="1"/>
<label for="terms_usr_1">Credit Card</label>
<input type="radio" name="terms_usr" id="terms_usr_2" value="2"/>
<label for="terms_usr_2">C.O.D</label>
[Code]....

I am trying to use the remove() jquery function.
I appended elements inside this div. But I want it where if a check box is checked then that element which is an a tag html element that will be removed.
The problem... when lets say append 3 <a> tag elements. when I remove all 3. Then append like 4.. I see like gaps. like I want it where if I delete the element it will float upwards. what that means that if I got 3 elements and I delete all 3 and then append 1 new one... then that new one should be shown at the top of the div. Not displayed a little bit lower then where the 3rd element we removed was located at.
It seems like that html code that is appended still stays there for some reason.

I have this query that does what I want it to do, find the class and remove an extra element within its parent:
$(".emptyTopNavOption").parent().children().first().remove();
But when there are multiple classes, it only deletes the first element in its query. As a successful test, I appended some CSS to ensure the query selected all classes and added a border to each element. So why does remove() not work? Is it a bug or is my query missing something?

If I have the following:
<div class="jcarousel-clip jcarousel-clip-horizontal" style="width:
459px; height: 220px;">
<ul id="mycarousel" class="jcarousel-list jcarousel-list-
horizontal" style="height: 220px; width: 918px; left: 0px;">
<li class="jcarousel-item jcarousel-item-horizontal jcarousel-
item-1 jcarousel-item-1-horizontal" jcarouselindex="1"></li>
<li class="jcarousel-item jcarousel-item-horizontal jcarousel-
item-2 jcarousel-item-2-horizontal" jcarouselindex="2"></li>
<li class="jcarousel-item jcarousel-item-horizontal jcarousel-
item-3 jcarousel-item-3-horizontal" jcarouselindex="3"></li>
</ul></div>
Trying to figure out how I can do a .each on each <li> and then add an additional style to the last <li> in the list.

I would like to achieve the following... I have the following list:
<ul class="menu">
<li><a href="something.html">First main</a></li>
<li><a href="something.html">Second main</a>
<ul class="sub-menu">
[Code].....
Now, I'd like to remove the link from the "Second main" because it has a submenu. I know that I can get that exact item using $("ul.sub-menu").parent() but how do I unwrap the link in it?

I am having difficulties to deal with a simple remove function.
I have an item list with "listitem" css class. I placed a button on each item to delete it. I am now trying to use the remove function to erase it from the page. I thought $(this).remove(); will work but it doesn't. I also tried something like this: $(this).parent('.listitem').remove(); but it didn't work.
When I write $('.listitem').remove(); it erased all the items of the list. I m just trying to be able to erase just the one clicked.

I am trying to insert and remove form element dynamically. What I was doing was some sort of recipe program where a user can prefer to add for elements as he/she is done inputting a recipe. He/She can also remove the ingredient if he/she opts to. Here is the link: [URL]
I already solved the problem but I am not sure if what I did is an efficient one. The thing I did was clone the first child of the form. But I realized that if I would put text inside the first child of the for, the duplicate field will also contain the same text as the first child which I don't want to happen. This is why, I set the display of the first child of the form as none. I am not sure if this would cause some problem when I would submit the whole form so that the inputs will be saved in the database since the first child is empty. I was thinking that as the form will be submitted, I would just remove the first child.

I have a few input button classes all with the same class. When a user clicks on the input button, then I disable the input button so the user does not click on it again. I want to make it so when the user goes back, all of the buttons of the same class are active again(including the one that the user just clicked on).

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've run into a problem on a particular project, and it seems to be browser specific. [code]...
Now, this works all fine and dandy in Firefox and Safari, but in the IE's, it will switch properly, but if you switch while in the middle of a movie playing and then switch back to it, the video is paused at the spot where the switch happened and will not play again. That does not happen in Firefox or Safari. Your thoughts? Is this just a cache thing with IE that can't be worked around?

I'm working on dynamic list with jQuery. I've appended hundreds of <li> elements with for loop to make very long list. When user scroll down again, remove older ones and append new ones at last of the list. I used$('li:lt(50)').remove() to remove first 5 elements from the list. At first, it works. But, for the second time, it always delete half of '50'. When I enter 100, only 50 elements deleted. How can it be? Could you check the ':lt(n)' selector and remove function? My HTML is very simple. only <UL> <LI> tags in the body. Tested on latest Chrome(ver.13.0.782), jQuery 1.6.2.

So I have a table with rows and basically I cloned it and then appended it underneath another table. The user can click on the plus button to clone the table (which on the UI looks just like a row of fields) over and over. Next to the plus button I have a minus button that I want to use to remove the cloned table. Here's my code for the add table button:
Basically what I need to do is write functionality for the remove button that when clicked removes the bottom most table. Is there functionality in jquery where you can say "find last occurrence of 'addrow' and remove it onclick"? [code]...

Let's say I have two lists for menus and one list for sortable content.
If I click on "A" in the #type list, the content list is sorted, the li's with the classes "B" and "D" are hidden by attaching a class of .hidden to display:none. In turn becoming:
My question is, how do I apply the new content results to the #location menu? If "B" and "D" are hidden then numbers "3" and "4" shouldn't be displayed. I'm having trouble getting the two to talk to each other. I've tried .is(':visible"), .each(), etc. and can't quite crack it.

I have three very normal drop down lists with multiple and size="4" attribute.. I have couple of text boxes too in my form. When I see the output in IE, textboxes appears plain and drop down lists with insets. Does anybody know how to remove these insets?
However, drop down lists appear perfect in NS and Mozilla. If I change the size of lists to 1, it appears fine in IE too. But, I need to have it's size set to 4.

In the following script all works fine except the "Remove all items".It adds and removes individual elements fine, but when I call the dropElems() function it removes up to the last 2. If I click it again, it removes only one.Finally, pressing one more time does remove all.I'm calling the same function to remove one element multiple times to remove all the elements, but it seems to stop short of the actual desired action.[code]
