I have noticed a few requests lately on the forum where there is a request for a dynamic dropdown list (<select...> tag) that would display one set of options if one condition is met, but a different set of options if a different condition is chosen. This is my attempt to solve this problem for other users. The following code is a template to show one way of how this question could be resolved.

I've been beating my head against a wall for a few days trying to get this working. I'm trying to create a dynamic menu where a user selects one item and another select list is shown, then another and another (and so on). Here is my JS, it *should* be taking the ID of the div, comparing it to the selected value and then showing another div by settings it's class property to visible:

I'm a complete rooking at javascript (and haven't looked at php in months), but am wondering if its possible to do the following with javascript. I have a listing of 10 to 16 teams. I'd like to be able to list the teams in a drop down select box. And when the user selects a team, that teams listing of players is than shown below. The user should than be able to toggle through the listing to review each time.

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.

View 3 Replies View RelatedI 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.
View 4 Replies View RelatedI'm trying to create a dynamic drop down box where the first drop down box populates the second drop down, but it isn't working. I have two tables; pricelist with fields,
-id
-groupname
-item
-price
groups with fields,
-id
-groupname
I've got the code and to me it looks as though it completely works, but i think its the fact that two of the fields have the same name, and it's causing problems.

I am trying to populate a drop down list in an HTML form that pulls it's data from a datbase. Basically, the users can manage the values via a differnt interface, but the web page will present what ever values are in a given list. I can make the list from the database as a set of value pairs, but I can't figure out how to take that list and "import it" into an HTML page. I didn't post any code since nothing comes close to working. If I have this list:
Item, Name
A001, Cats
A002, Dogs
A003, Birds
what do I do to pull this into a form?

View 4 Replies View RelatedI have a form that has a pretty complicated combo box - a user starts typing text, it queries a database for matches, and displays the results to the user. The user can then select the match they desire and it has a value id, which I am currently sending to a hidden field in the form. So, for example: user starts typing in a movie name, Seven - it returns Seven and user selects it. The form submits the id of the movie seven (say 12) to a hidden field.
Where I am stumped: Once a user selects a movie title, I have another drop down select box that is to display the available formats of the movie by querying my database based on the product id (12) and returning the available formats in the list:
DVD
BLUERAY
VHS
I am pretty good at programming, but I cannot figure this out - how to make the select box fire and return results once the value for the textbox has been captured.
i am currently working on aptana studio nokia wrt plugin to develop a mobile widget where i need to retrieve data from database. i've created a java servlet in eclipse to connect and execute query to the ms sql server 2005 database. in aptana, i am using js file and html file, i'm able to connect to the servlet to retrieve and process the data (split the data) into an array and display the retrieved value (array) on screen. but now i need to put the retrieved value (array) into a drop down list for selection, how could i do that?

I'm trying to write a script with two standard drop down boxes. One
contains days one contains the month. I want to update the options in
the days box everytime the month is changed... i.e select August, and
days are filled up to 31, select September and only 30. The part where
I am having difficulty is that after the onChange event has triggered
and I have checked what the new month is, filling the box with relevant
values is tricky. Code:

If i have a drop down list on my website, and i want to use javascript to change its selected value,however, i do not have the id/name attribute of the option i want to select, only have the "value" attribute of the option, can it be done?
<select name="category">
<option value="">No Preference</option>
<option value="Apples">Apples</option>
<option value="Oranges">Oranges</option>
<option value="Pears">Pears</option>
<option value="Banana">Banana</option>
</select>
I imagine somehow.. selecting the options and looping through them and match the value. Really new to javascript,
I know very little javascript, I am more familiar with php. I am working with javascript code, php/mysql backend and smarty templates. I am trying to get the textfield box to update with a variable from the database based on the selection from the drop down field. My dynamic drop down selection works fine, it is pulling the data from the database (example:$item[i].PARTS_RATE_ID}) just fine. But I want the textfield ('parts_price['+iteration+']') to dynamically show the $item[i].PARTS_RATE_COST from the database (in the parts section), associated with the $item array from the "parts description".

The intention is that when you select a site from the list, the banner underneath changes. However, I can only get it to do this once, then it simply refuses to let you select anything else. This is the code I am using to change it:
function defineimage()
{
if (document.forms[0].gourl.value = "http://jeff.zhomg.com")
{
document.images.linkimage.src = '/images/exchange/jeff.gif'
}
else if (document.forms[0].gourl.value = "http://www.strangedrawingsartgallery.com")

How can I make a list menu appear when I select an option from a drop down list or menu?
View 11 Replies View RelatedI am trying to create a drop down list which depend to the value selected from the previous drop down list. I can add it without problem, but If I change again the value of the first drop down list I would like to remove the previous drop down list generated from the first value. If I try to remove it when I create the element, it even does not create the element, the remove element function seems to work because when you click on the remove link it works.

When the page loads there will already be a drop-down on the page, here's an example of the drop down.
<select id="dropdown">
<option value="2121S">Option text</option>
<option value="2122S">Option text</option>
<option value="2123S">Option text</option>
<option value="2121A">Option text</option>
<option value="2122A">Option text</option>
<option value="2121K">Option text</option>
</select>
On page load it will evaluate this drop-down and repopulate it determined on their values. If there is an S in any of the values the drop-down will generate an option for 'S' like so.. <option value="s">S Option Text</option> And for the first code example in this post - the Javascript would be able to repopulate the drop-down with the following:

I am asking jQuery to tell me which drop down option is selected in a drop down list - like this:
I would like to check if this was successful before I proceed. What are the possible return values for this statement?
If no id exists.
If no option is selected.
If some other problem occurred.
In these cases am I expecting a null return; an undefined return, a false return value?
And, based upon the complete set of return possibilities, what would be the best and most comprehensive tests I could apply to cover every base.
I am building a jurisdiction calculator for issues on/off Indian reservations. I'd like the user to select 3 variables (radio buttons would also work) - whether the victim is Indian/Non, the perpetrator is Indian/Non, and whether the crime occurred On/Off a reservation and have a div that displays the possible jurisdiction outcomes based on the selections.For instance, if the user selects Victim: Non-Indian, Perp: Indian, Location: On reservation, the possible jurisdiction results would appear.
Here is the basic html breakdown:
<select id="VictimSelector" name="VictimSelector">
<option selected="selected"></option>
<option>Indian</option>

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 . . . .

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