JQuery :: Dynamically Creating / Removing Items From List

Jun 3, 2009

I'm trying to dynamically create and remove items from a list, it works just fine. Sort of, I can remove items, and create items, but once an item has been created, I cannot remove it again, but I can remove the items present when the page loads.

Here is my code
<div class="list">
<div class="item">
<input type="text" value="" /> <a href="" class="removeitem">Remove this item</a>
</div><div class="item">
<input type="text" value="" /> <a href="" class="removeitem">Remove this item</a>
</div><a href="" class="additem">Add item to list</a>
</div><script type="text/javascript">
// Add item to list
$('.additem').click(function(){
var template = $($(this).prev().get(0)).clone();
template.insertBefore($(this));
return false;
});
// Remove item from list
$('.removeitem').click(function(){
$(this).prev().parent().remove();
return false;
});
</script>
I can remove the 2 original items, but when I create new ones, they cannot be removed.

data: "company=" + $(this).val(),

JQuery :: Create An Unordered List Dynamically And Turn It Into Tabs?

Jul 7, 2010

I'm trying to create an unordered list dynamically and then turn it into jQuery UI tabs... I think I'm having problem with syntax here, I managed to create the list and turn it into the widget, but those tabs don't look right, they have the outline of the widget but the content doesn't have actual tabs, so my guess is it only 'kind of worked'

$
(
"#doc3"
).
append

[Code].....

is this the way to do it? (for now its just the test, eventually i want to use for loop to create the list and pull data from an array)

Dynamically Change Row Colour On Dynamically Generated Table Rows

Nov 25, 2005

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?

Multiple Drop Down With Dynamic List (PHP - MySql - AJAX) - Filter The Results Into A List

Aug 2, 2011

I have a table that has parts with multiple characteristics. Part Number, Height, Width, Capacity, Price, Etc. I would like to have a drop downs for all of these values, when a user selects one of these values it will filter the results into a list. Ex. user selects a part that has a Height of 6 and width of 10 it will only list those parts. As I said earlier, I have a script that will give me all the parts, however I am not able to make the onchange list parts with multiple values.

JQuery :: Limit If A Value Can Be Selected In A Drop Down List (select) Based On Other List

Jun 9, 2009

I have a page that displays a list of people playing in a tournament. I need to be able to generate a Leaderboard based on which players are manually selected by the admin. Next to each person there is a drop-down list. An admin can go in and select a "slot" that a player should be in on the leader board from 1 to 8, or leave it blank if none. What I need to figure out how to do is the following, when a change event happens on a drop-down list, and say the value 5 is selected, I need to check to make sure that 5 is not already selected in one of the other players drop-down lists, in other words, that the 5th leaderboard slot is not already full. if it is, display an error message and make them change that one first. how to do that with jQuery? I'm thinking it will have something to do with the each() function, but not sure exactly how the logic should work.

JQuery :: Access The 'a Href' In A List Item In An Unordered List??

Oct 8, 2010

i have a menu and i would like to change the color of the Categories which have subcategories only. In my example the basic categories are: News , Announcements , Contact and Career. Only Announcements and Career categories have subcategories. So i would like those two to turn green. The fact is that the list items include a href ,so i don't know how to access those "a href" combined with "this".

<ul id="my_menu">
<li id="id0"><a href="#" style="text-decoration:none">News</a></li>
<li id="id1"><a href="#" style="text-decoration:none">Announcements</a>

JQuery :: Simple Expand/collapse List : Big Gap Of Space After The List?

Jun 2, 2010

I have been trying to make an expand/collapse (essentially accordion) list. So far, everything works and looks fine in Firefox, Safari, and Chrome, but in IE8, the page height is static when it loads, with a page height being as if all headers in the list were expanded. The expand/collapse functionality works,but as you can imagine, there is this big gap of space after the list.

The html markup uses <h2> tags for the always-visible header portion and a <div> for the expanding/collapsing content. The <div> content contains form elements and everything is enclosed in a form tag.Anyways, here is the jQuery code:

$(document).ready(function() {
$('<img src="plus.png" class="icon" />').prependTo('.header');
$('.content').hide();[code].....

Update A Dropdown List Based On The Selection Of A Previous List

Aug 16, 2010

i am writing a script that will update a dropdown list based on the selection of a previous list. the script is run by a PHP script, so instead of posting the PHP, i will post an example client-side script. the hierachy is: category, sub category, brand (but sometimes there exists no sub category and the PHP script queries and adds brands instead) everything works correctly, except for one major issue: you can not change the selection of the third (brand) box this could be an easy fix for some coders, but i am not experienced in javascript and could really use some help. here is an example script, sorry it is so long

PHP Drop Down List Selection Populates Second Dropdown List Or Text Box?

Jul 13, 2011

I have been struggling on a bit of code for a while now. I need to populate a second drop down list (Region) based upon the selection of the first (County).I have found a piece of code that works on its own and have adapted to suit my needs - see below. However, when I drop it into my main page the javascript is not working. It's because of the formObject but I just don't know enough to resolve this! Furthermore, I need the textboxes the user has already completed in the form to retain their value once the javascript kicks in as the completed form will submit to a database.This piece of code is working well . . . .

<?php

$link = mysql_connect('myhost', 'myusername', 'mypassword') or die('Could not connect: ' . mysql_error());
mysql_select_db('mydatabase') or die('Could not select database');[code]......

JQuery :: Inserting A List Element Into An Ordered List?

Jul 19, 2010

I'm working on a project that requires dynamic manipulation of an ordered list -- adding and removing elements in response to the user pressing buttons. I've run in to some odd behavior. Here's my code:

HTML

<ol id="track-list">
<li>Static Content Here</li>
</ol>
<input type="button" id="add-track" value="Add Track" />

jQuery:

$("#add-track").click(function(){
var listEl = $("<li>Dynamic Content Here</li>");
listEl.hide();

[code]....

Looks pretty straightforward, problem is when I add the new list element it does not prepend it with any number (being part of an ordered list). Now if I remove the hide and fadeIn lines (just append it), it inserts it correctly with a number before it, but I want this to look pretty being jQuery and all...

Jukebox - Replay List And - Create Non Dropdown List ?

Sep 1, 2010

I am trying to construct a Jukebox for my website. I have spent considerable time all over the WEB and at this forum which addressed the issue in a 50 page thread. Please see: [url]

I got a lot of ideas from this thread but still cannot figure a way to do the following within the Jukebox. These are my main two questions for everything below:

1.How can I have the Jukebox cycle through all tunes and then start over from the beginning?

2.How can I allow the user to select a tune from a list but not a drop down list, have the Jukebox start from the users selection and then play all songs to the end. Then as in #1, start over from the beginning?

Per this thread I came away with basically two ways to assemble the jukebox. One uses links in a drop down list which the user can choose from. The other is to use an .m3u playlist. The user can only select a playlist from the drop down.

Below, I have included the code for each Jukebox. To see the Jukeboxes in action please go to my website where I have posted some test pages exhibiting the jukeboxes that I am referring to.

The following is the Jukebox which utilizes an .m3u playlist. If I end up using this idea I would like the tunes in the .m3u playlist to be displayed and allow the user to be able to choose a tune in the list. Then have the list play to the end of all tunes in the list. Then start over from the beginning of the list. After this code is the .m3u playlist.

Go to url removed and click on the link that says:

Jukebox utilizing an .m3u playlist:

Here is the .m3u playlist for the above code:

The following code is for the Jukebox that has a list of links in a dropdown list. If I go with this idea, I would like for the list not to be a dropdown list but just a list of tunes. The user should be able to click on any tune in the list and the player should start from that point, play all the remaining tunes in the list and then start from the beginning.

Go to url removed and click on the link that says:

Another idea I found on the WEB also uses an .m3u playlist. The good thing about it is that it lists all the tunes in the playlist which the user can then select from. This jukebox calls up an entire Windows Media Player. If I was to use this idea I would like to be able to disable the left side of the player where the user has options such as burning to CD, Media Guide, Radio Tuner etc

JQuery :: Select A Sub-list From A Long List?

Aug 14, 2009

I have a MySQL table with 90 columns and I want the users to be able to select any columns they concern and output the result accordingly. In the front-end, I can use a group of checkbox which looks very ugly and I can not setup the orders for selected columns. Is there a plug-in or some examples in jQuery, that I can make 2 parallel boxes (i.e. an original-box and a selected-box). the original- box lists all of the column names at the beginning and there is a way to move items between two boxes. And the order of items in the selected-box can be adjusted. the items in the selected-box will be used to build into an array in my backend code.
