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.
I 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.
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'd like to limit the number of selections a user can make in a multiple select listbox. I have a note on the interface to say that only x no. of items should be selected and I check the number server side but I'd like to implement some javascript to do the same on the client side. Ideally I'd like the javascript to work in IE5+ and Netscape6+.
I am having trouble getting the selected option in a list of more than 20 items in sharepoint, The code below works for lists of 20 or less but not for lists of greater than 20. If any one has a snipet of code that will enable me to set a variable with the selected value from a complex dropdown it
The page I am building has 4 columns on it and I want the selected value ofa drop down list box to control the number of columns that appear on the page.
I have a multiple select list <select id=mylist name=mylist[]> <option id=1>first</option> <option id=2>second</option> <option id=3>third</option> <option id=4>fourth</option> <option id=5>fifth</option> </select>
Then I have a string of id's that I want to set to selected like so. var selectedIds = '1,3,5'; Is it possible to use jquery (preferably in a one liner) to set first, third and fifth to selected.?
There is a drop down list on my Web page with various values to be selected by the user. Once the user has selected a value, he/she clicks on the submit button. When he/she does that I would like 2 things to happen: the selected value of the drop down list is passed to another html page which opens in a new brower window open.
I'm a newbie. I have just working with jQuery for 2 hours. For example I have a drop down list like this:
<select> <option>Fruit</option> <option>Color</option> </select> If I select Fruit, another drop down list appers and give me some selections: <select>
When user select, for example, option 3, how can i find which was the previously selected option? etc... I've found some javascript example that evaluate "previousIndex" property of the select element but it doesn't work at all
It will be included on the pages in the list and I'd like the list to remember the last selected (showing the user what page in the list they're on). I can't figure out how (other than manually doing it on every page).
The other thing is that the + and - buttons change the item selected for ALL select lists on a page, it's pretty cool but not what I'd like it to do. You can see it working on [URL]..
iam trying to use 5 drop downs in my form for user to select languages and each select drop down should not allow the user to select the same language again and all my drop downs are populating individually from the DB on the page so if "English" is selected for "dropdown 1" then again "drop down 2" should not allow "English" to be selected.
I 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 need to be able to change the fields of a form based on a drop-down list. Like if someone picks option A field 1 shows and if they change it to option B field 1 and 2 show up without reloading the page.
If you need me to explain more I will try to do a better job. If I could be pointed in the general direction that would be great, I dont exactly need to be spoon-fed, although I do like spoons if you catch my drift .
My mission: Open/collapse TD cells based on items selected in a list box. Getting no response from jQuery so I've done something wrong but cant quite get there. Listbox 'mainselect' contains option values that refer to names of TDs in a table. When a mainselect option is clicked, it will toggle to open or close the referenced TD list box by option value. Does hide/show make a TD 'blank' or actually set it's width to '0'? I want it to close, moving other cells left.
I'm trying to change the selected index of a List/Menu based on the value of a Text field, I can pull data and alerts, but setting the selection is not working.

I need to change all select lists options to "Shipped" if admin clicks on "Shipped" on top of the page and "Processing" if customer clicks on "Processing" link (<a href="javascript:select_processing()">Processing</a>)
I have a drop down with approx. 200 <option> elements, each option element has a value such as value="1", value="23", etc. Given a list of values, such as 5, 34, 43, 68, 123, how can pass those values to a function and then insert selected for each corresponding element?
I am maintaining a site which is written in ASP. Now i have to create some new pages.
In one page we have a table with many rows. Now, I want to enable or disable(showing and hiding also) 2 rows of this table depending upon the value selected by the user from a drop down list.
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 3 ASP list boxes. I would like to populate the second list box based on the selection in the first list box and based on the selection in the second list box, populate the third. I would like to do this using AJAX. How can I do it? Can someone please give me the code snippet as I am a complete noob when it comes to AJAX and I kinda am running outta time to finish implementing it. Additionally, should I use ASP boxes or HTML <select> tag?
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.
cna anyone tell me how to use the Select = "selected" option for a simple dropdown. for example when someone chooses c it will have a code like <option selected="">c</option> (am I doing it right, well if you got a firebug some site with dropdowns offers that option) so can anyone tell me how that works. I will be using it for a purpose of just selecting parts on my array, well incorporating it
