AJAX :: Populate The Options Of 5 Dropdown Boxes?
Jan 16, 2011
I have a product select page that is really slow to use because 6 dropdowns must be populated and the page reloads after selecting each box, to get the options for the next box.
I want to speed it up as follows:
1) User selects one of 50 products from a dropdown list.
2) Page reloads, and all the possible options for the remaining 5 dropdown boxes are now populated (ie. list options all stored client side)
3) User can freely input the remaining 5 dropdowns without the page reloading.

I am populating a number of Select boxes on the server-side with a large number of options. I'd like to get the response size down without taxing the client browser too much. What do you think is the most efficient way to approach this problem?
Here are some considerations: The option text/values do not change very often, but could potentially change in the future. The page that holds the select boxes should never be cached, there are other aspects of the page that need to remain fresh. Firebug with YSlow is saying that the primed cache size of the page is 300Kb with all the select dropdowns and options, if I remove the options, the primed cache size of the page is 80Kb. I am considering breaking out the text/value pairs for the select boxes into a separate file that is cache-able calling it "valueTextPairs.js" and referencing it with a query string and some sort of server-generated MD5 hash of the data, so that if any of the values change, the client's cached version will be replaced by the latest version. Like so:[URL]...
Provided I do this, I anticipate that the primed cache size of the page will be reduced down to 80Kb (which I like) -- however, before I take the plunge, I am curious what you all think the performance effect will be?
I know the number of bytes on the wire will be reduced, but will this put a lot of additional pressure on the client's browser because I'd need to traverse the name/value pairs and add the options to the select boxes dynamically on the client end? If it seems reasonable to do this, what jQuery approach would be the most efficient? $('#selectId').html(options) with options = one big string? Adding each child option to the select in a loop? Something else?
Some client end folks are using IE6 so I am trying to tax the browser as little as possible, while also reducing the size of each request, trying to find a happy medium..

Below is the code I use to populate a textboxes (compaddress) when I select the compname from the dropdown. I would like to be able to populate other textboxes such as the compdescription, compmaincontact and others when I select the compname from the dropdown. I think that I need an array but I really would like some advice on how to do it as all of my attempts have failed so far
Code:
<script type="text/javascript">
function showname(what)
{
what.form.textfield.value=what.options[what.selectedIndex].title
}
window.onload=function() {
showname(document.form1.number)
}
[Code]...

I'm looking for four level connected drop down boxes. Unlike all the scripts I have seen on the internet I need all the options to be available if nothing is selected in the previous drop down. So I want something like combination of connected drop downs and ordinary drop down. If the selection is made, display appropriate options in other drop downs... Hope I'm clear...
[Code]....

Actually this is the same like the pop-up calendar but the only difference is I don't want numbers, I need a list of options so user can choose and when they select, it will transfer to the textbox right away like the calendar. I have a form and trying to use a pop-up window to select an option then transfer the option selected to show on the textbox. I have 10 textboxes and all of them has a "Select" button to pop-up the option list. BTW, the "SELECT" button will populate the same option list.
Here is my html code:
<select id="droplist" name="droplist" size="1" >
<option>Click to select...</option>
<?php foreach ($designation_list as $descode => $prompt) : ?>
<option <?php echo helper_selected($prompt == $form['droplist']); ?> value="<?php echo $prompt; ?>" style="width:500"><?php safeEcho($prompt); ?> </option>
<?php endforeach; ?>
</select>
Below is array:
<?php
$designation_list = array(
"00111" =>"Aloha of the Pacific/Transfer Assistance Program for High Income Students",
"71122" =>"Aloha",
"71231" =>"Free Housing Information",
"71232" => "Drama Queen and King",
"98765" => "Aloha Boy Home of the Land",
"12345" => "Aloha Home",
);
I wanted to use the option list over and over again for the 10 textboxes. Is that possible?
Below is my sample code but didn't work.
//javascript
var testpopup5 = new PopupWindow("testdiv5");
testpopup5.offsetX=-20;
testpopup5.offsetY=20;
testpopup5.autoHide();
var testpopup5input=null; .....
I get this code from somewhere else but it doesn't work on me.

I have a page that runs a lot of calculations.The math is computed on the fly using java scriptwhen all the calcs are in, prior to form submission the user needs to evaluate which numbers they prefer, and from there, once they select them, the form, based on those choices, will perform one last calclets say we have 3 result fields
r1 = 2000
r2 = 3000
r3 = 4000
what i want to do is have a select field be able to display those values at the bottom of the page;for example
<select name="s1">
<option value=[field contents of r1 above]>[field contents of r1 above]</option>
<option value=[field contents of r2 above]>[field contents of r2 above]</option>

The following PHP code populates a dropdown list of Projects. I would like to be able to click on a Project Name in the list and have its corresponding list of Characters appear beside it. How can I tie jquery into this as it's running? All the jquery examples I see are for hard coded HTML data instead of a PHP loop grabbing from a database.
Code:
//creates the Project dropdown list
while ($proj = mysql_fetch_array($project)){
$id_proj = $proj['projid'];
$name_proj = htmlspecialchars($proj['projectName']);
[Code]....
I don't care if it's a clickable list of anchors instead of a dropdown. Also, I don't care whether people have javascript enabled as this is for my personal use.

I am looking to create a set of three combo boxes with around 15 options in each. If an option is selected in one of the three boxes, it is removed as an option from the others.
Dropbox Box 1 Options: 1,2,3,...,15
Dropbox Box 2 Options: 1,2,3,...,15
Dropbox Box 3 Options: 1,2,3,...,15
[Code].....
So if the user changes there mind before submit, it repopulates each box with the proper items.

Im working on a backend panel where i populate a simple table with a few text boxes in there so they can update some values. I also have at the end of every row in the table an Edit, Delete & Save button. When i hit the save button i would like to update that entry in the database.
My Problem is that i need a value from the table before hitting a submit button, and the element names are dynamically created meaning ill likely need a variable sent from php to javascript and once i have the value in javascript ill need to send it back over to the php to manipulate and send to the server.
From wat i can gather using 'document.form.element.value' is the best way to go, hence why i posted this in javascript when most of my code is php.

I have a drop down with alot of options say about 6000 cities and
districts. I need to select all options if user selects "All checkbox".
I use "on change" and a for loop to do this, but it takes a lot of time
to select all these options. Is there any faster way to select all
these options?
function selectAll()
{
var element = document.getElementById("location");
var length = document.getElementById("location").length;
for(var i=0; i<length; i++)
{
element.options[i].selected=true;
}
}

I have two dropdown lists, and I want to have each option from the first dropdown list to give the specific options on the second dropdown list. For instance,
<select name="module">
<option value="pic1.jpg>TM1</option>
<option value="pic2.jpg>TM2</option>
<option value="pic3.jpg>TM3</option>
[Code].....
Note: The option values are just examples, but each option must have a value in order for other things to work.
Here is what I need to do:
If TM1 is selected, only Box1 and Box 2 are available (Box3 is removed from the dropdown "location" list);
If TM2 is selected, only Box 2 is available (Box 1 and 3 are removed from the dropdown "location" list);
If TM3 is selected, all options in the dropdown "location" list are available.

I have two dropdown lists, and I want to have each option from the first dropdown list to give the specific options on the second dropdown list.Anyway, let me show you what I really want to do. Please see the code below. If you want to properly run this, please make six dummy images and name them as followed: silo_1_ empty.jpg, silo_2_empty.jpg, silo_3_empty.jpg, tm1.jpg, tm2.jpg, tm3.jpg.What I want to do next is to apply a restriction to the dropdown lists. For instance, if TM#1 is selected, only Silo1 can be selected from the LOCATIONS, and Silo2 and 3 will be removed from the option. If TM#2 is selected, Silo 2 and 3 can be selected and Silo 1 will be removed. TM#3 can be in all locations.
In total, there are 12 modules and 20 locations. Each module image can only appear in one location at a time, but the options to select a location are restricted.

Have a WAMP setup with Apache, PHP and Mysql service and I�m working on a HTML form which will have two drop-down controls where information is extracted from two tables in my DB.The first drop-down list called (name="sel_ControlArea") will decide what information the second drop-down list will have.So far I have managed to populate them when the page is loaded using PHP but run into problem when I make a change on the first drop-down list.Question one: What is the best/correct way to solve this problem?Is it to load all information into PHP arrays and then translate these to Javascript arrays, or should I go for AJAX, or XML or are there any other better ways ?I have tried to solve this using the first method, put data in a PHP array but run into problem with this data not properly loaded.This is first time for me to pose a question so please let me know if I have left out some important information or if I should describe this problem in a different way.

I don't know how to evaluate the no-blank selections against each other from a form as follows: .
I have a form with 6 dropdown fields, each containing a selection of 30 options (the 30 options are the same for each dropdown list). The user needs to select 'one of the 30 options' from each dropdown selection, but each option they select must be unique (no duplicate selections) or it must be left blank. E.g. The user can select Option3 within "dropdown1", but must select a different option for the other dropdowns - OR leave them unselected.
