JQuery :: Dump Large Array Into Dropdown List?
Mar 26, 2010
I've a large array of nearly 5000 entries and trying to populate those entries into a dropdown list of my webpage. By doing that so, it is taking so much time ( nearly 30 seconds ) and is freezing the page.
Is there any way to load such a big array into dropdown in efficient manner...
var handles = [ ... around 5000 entries .... ];
function populateHandles(){
objSub = document.getElementById('listBox');
for(x=0; x < handles.length; x++){
[Code]....

I have two dropdown lists with the second one being dependent on the selection in the first.
Options in list 1: 1,3 or 4
List two should be enabled when 3 or 4 is selected in list 1.
So far so good, managed to get it to work with only one set of lists, but I actually have 18 of those sets in this form:
<select name="fw[$i]" id="fw[$i]">
<option value="1">FWH</option>
<option value="3">links</option>
<option value="4">rechts</option>
[Code]....
I'm not that adept in javascript programming, more like a trial and error guy, how has hit the wall with this problem.

I've been told that jQuery can do this.
Simple form which includes a drop down list of users obtained from a database which is displayed using a form select entry with options for each entry. problem is, the list can be quite long, upwards of several hundred.
In PHP, I added a filter box (text box) which the visitor can enter in a substring that is then used to obtain and display only matching entries. Works great, but it needs to reload the page to do its thing.
I've been told that jQuery can be used to do the same thing without having to reload the whole page.
The filter box would be used to call an existing PHP script which obtains the names based on the filtered string. I can change this script to output the data in any format necessary including raw format to full option formatted strings.
how to set this up so that it gets called and replaces the current option content.

I need a plugin or a idea about how to develop a pagination using jQuery (JSON dict coming from the DB (postgre)), but i cant get a list of all itens in the DB. I tried using offset and limit from the DB, but i didnt like the large algorithm. All i need is: develop a pagination that gives me only 20 rows from the DB (without calling a query to paginate all table from DB) and build a pagination with "first page, previous page, X-2, X-1, X, X+1, X+2, next page, last page" (X = number of actual page).

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

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]......

The correct syntax for an array literal would be:
this.managers [ "DOE, JANE", "DOE, JOHN", "BUSH, GEORGE W" ];
(which works)
My questioin is, how do you recreate this same syntax pulling from a
recordset containing over 3500 records such as:
aManagerName = "DOE, JANE", "DOE, JOHN", "BUSH, GEORGE W", etc...
because
this.managers [ aManagerName ];
(does not work)

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¦

I have, inside a wrapper a rectangular div where in the middle there is an image.now the idea is that when i click the image the inside of this div change and the inside divides itself in two other div, the upper one where i should put a dropdown list (with things inside), and a lower div where should be appear the results of a db.The part where I make a choice from the list and in the lower div the images from db appear is all right( i think:))Is it possible with this language clear a div and the put two little different div inside it and add a dropdown list?

I'm looking for a way to change the value of an asp.net dropdown list based on the query string using JQuery. The idea is to allow the user to select a category from a top-nav menu. Based on that selection, the query string is appended with their selection. I then want to rip the selected value from the query string and apply it to a dropdown list that will filter a GridView.
The sticky point might be that the navigation lives in a parent page while the filter and gridview for displaying data is nested into that page inside of an <iframe>.

I am trying to use the code below to create the following behavior for comboboxes with class = "requiredCombo" -
1. If the selected index is 0, I want the font to be grey; otherwise black.
2. When the mouse enters the box, I want to change the font to black while the user is making a selection.
3. If the mouse leaves the combo and the user did not click (that is, they just ran the mouse over the combobox) and the selected index is 0, I want the font to be grey otherwise black.
4. If the user clicks on a selection and it is not index = 0 I want the font to be black.
The following code works great in Firefox but in IE 7 when I include the "mouseleave" code, the dropdown list opens up when I click the dropdown but as soon as I try to move into the list to make a selection, the dropdown list closes. Any suggestions what I can do?

I tried to use it in my app and I only have the first letter of each item in the dropdown list. So it is very difficult to select the good option I have search any information in these forums about this trouble, but no success.
[Code]...
perhaps this code is wrong and json format not good ? so, the first item of dropdown list is fine in the input box, but all items with only one letter in dropdown list. I hope any body can spend a few time and help me a little to understand that is wrong, as I could terminate my app.

I have 2 drop down list that are populated through mysql. They both contain data upon initial page load. However when you select an option from drop down #1 it populates drop down 2 with data associated to it. Sometimes the 2nd drop down list has selected data already and I need it to be cleared back to the first option when the first drop down is selected.
the following code is what I use to populate the second drop down
$.ajax
({
type: "POST",
data: "company=" + $(this).val(),

});
});
});
