Limit Number Of Selections In Multiple Select List Box

Jul 20, 2005

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+.

JQuery :: Select List With Multiple Selections Hack

Jul 6, 2009

When using a select combo box that has multiple selections enabled, my server was not seeing it as an array. It was only seeing it as a single variable value. All I did to correct this was add [] and the end of the name attribute.
Ex.
[code]<select name="categories[]" id="categories" multiple="multiple"
size="4">[/code]
Now my LAMP server sees this variable as an array in the $_REQUEST

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.

Enable/disbable Multiple Select List

Nov 24, 2004

i have a select element:

<select name="test1[]" size="5" multiple id="test1[]" >
and I have two radio buttons to enable/disable:
HTML Code:
<INPUT TYPE=radio NAME="f1" VALUE="option 1" (this.value)"><INPUT TYPE=radio NAME="f1" VALUE="option 2" (this.value)">
Javascript is as follow:
Code:
function Disab (val) {
frm=document.send;
if(val=="option 1") {
frm.test1.disabled=true;

} else {
frm.test1.disabled=false;}
}

It appears when I name the select element with '[]' it doesn't work. Is there another way to gather data from element via php or is there another way to identifiy the element to disable.

Sum Of Multiple Dropdown Value Selections?

Feb 25, 2011

Not a seasonsed JS user; I would like to have a number of dropdown forms on a page and have JS sum the total value up as the user makes their way down the page and selects values. I've googled the daylights out of this and come up with a proof of concept below - if I could get it to work right, I would apply to a larger page. It will live on a Sharepoint server so I can't just use PHP to handle the summing.

Limit To Number Of Loop Iterations?

Mar 24, 2011

I wrote a short javascript code to try to solve a math puzzle. It involves iterating 50,000 times through a for loop. Nested in each of those iterations is another for loop with 50,000 iterations of its own. I think that's 2.5 billion altogether. Each times it compares two numbers that are being incremented.

I'm doing this in JS because I can't any of the Java I learned a few years ago...

I tested the code with much smaller numbers and it worked. With the big numbers my browsers are not responding, not surprisingly (I'm using the latest firefox on the latest mac os).

Will the code finish running tonight? Next week? In 10 years?

Limit On Number Or Size Of Javascript Variables

Jul 20, 2005

There will be a number of list boxes and other controls, with pop-up windows
to edit certain properties. It's the kind of thing I would normally have
done in VB but I want it to be browser-based. I've only used javascript for
trivial things before so this would be my first serious javascript
development. I would like it to run on all reasonably recent browsers.

The form starts with all the initial values being received from the server
(presumably just by pre-initialised data structures). The user tinkers with
it and when he is happy he presses 'submit' and the whole lot is submitted
to the server (presumably as a form post). This would be a few kb of data,
possibly 100 individual values but obviously in various data structures. I
guess there would be a few hundred lines of javascript code to manipulate
it.

My question is, is there likely to be a problem with manipulating and
sending this amount of data in Javascript. Sorry if this is a dumb question,
but like I said, I only used javascript for tiny programs before, so I'm a
bit unsure about its capabilities.

Coding HTML/JS Form With Multiple Selections?

May 20, 2011

I need help setting up a form, I want to do some pretty neat things: It will say: What countries do you want to visit? [FIELD] Part 1: I want that when a user starts typing into the field, it will suggest under things that match what you have typed so far, sort of like facebook search does. So I would need a list of recognized country names. Now for example imagine I was using this, and I typed in M, it would list under a max of 5 valid entries begining with M, if I typed in Me, it would list the ones begining with Me, if I typed in Mex, it would show Mexico. Now the user would have to click this drop down suggestion to choose it.Part2: I want once a user clicks on a suggestion, it will "pop under" the input box or somewhere, with a "x" beside it to remove it. The user can now type in another country, and when it is clicked it too appears as a sort of "icon" under the input box or somewhere, with an "x" beside it. Clicking the x removes the country from the current list of countries. Once he is done, he goes on to other fields and the selected countries remain visible. Once a user submits the form, I want to get only the countries that were visible to him.

**An alternative idea, if this one is too complicated, would be to have a drop list with all countries in it, and once a person clicks one, it will remain and a "+" sign will appear under it. When pressed, another dropdown menu will appear so the person can choose another country from the second drop down, etc. OFC all selected countries can have an X to remove them. Idk how to do this either. how to do something like this, where do you recommend I start? Any ideas? I tried searching but I'm not sure what to call this so I couldn't find anything in the search.

Selections From Drop-Down Box Automaticly Create Multiple Tables?

Wonder if there is a way to have my Drop-Down box selections create individule single row/dual colume tables for each item that was selected from the drop-down box. An example would be:

1: I selected 3 items from my drop-down box at one time (my drop-down box allows multiple selections).

2: I click a button call "Create Template" and three new single row/dual colume tables are created with the names if the items.

Here is what I have so far, but need a little help. Notice I have added the three tables in to show how it should look but this is for information only as these should be created automaticaly.

Jquery :: Building Dynamic List Of Items - Adding Index Number?

JQuery :: Determine If Autocomplete Returns An Empty List And Number Of Records Returned?

Jun 5, 2009

While using jQuery, I found that I needed to know how many records were returned and also if the result set returned was empty. After searching the jQuery documentation I couldn't find any property or method that returned this value, so I've added that functionality
myself and wanted to share it with the group.

1) Determine the number of records returned: I wanted to show the user how many results were returned after they start typing into the autocomplete field similar to how Google indicates the number of results found when you start typing in the search box. At first I thought the max parameter in the function formatItem returned this value. However, it returns the max option that you set it to. So if your query returns 100 records and you set max to 25, it'll obviously return 25 (not what I wanted).So after trying various things, I looked at the jQuery code and simply added the number of records returned by the database to the formateItem function. In the fillList() function around line 660 I added the data.length parameter:

var formatted = options.formatItem(data[i].data, i+1, max, data [i].value, term, data.length);And in my autocomplete code, I added the parameter to the end of theparam list:formatItem: function(data, i, total, value, searchTerm, totalResults)So now whenever a new search is preformed, I get back the number ofsearch result from the database.

2) Determine if a result set returned was empty I wanted to update a <div> with a message like "no records found" whenever the query yielded no results. Again, after searching the jQuery documentation, I couldn't find any property or method that would indicate this so I added it to the code. In the request function after the line var data = cache.load(term); I added the following:

if (!data) {
options.isEmpty(0);
} else {
