[jQuery] Re: Limit if a value can be selected in a drop down list (select) based on other list
$(select).change(function() {
var sval = $(this).va();
if(sal == 5) {
} else {
// do something
}
});

Hi, I have a little problem.
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.
Any idea 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.
[jQuery] Re: Limit if a value can be selected in a drop down list (select) based on other list
But how do I add in the fact that I need to check that the currently
selected value is not already selected in one of the other 50 drop-
down lists on the page? Somehow I need to check if $(this).val() ==
compare to each selected value in every select on the page.
Thanks

Ok, figured it out, just in case someone else needs it (there is
probably a better way yet...
//check to make sure the slot is not already full
var selectedValue;
var revert = false;
$('.ddl_slots').change(function() {
selectedValue = $(this).val();
$('.ddl_slots').each(function() {
if ($(this).val() == selectedValue)
{
revert = true;
}
});
if (revert)
{
$(this).val();
alert(This slot is already selected for another
player);
}
});

[jQuery] Re: Limit if a value can be selected in a drop down list (select) based on other list
Hi All, here is a slight improvement and fix. Turns out you also need
to check to make sure that the list id you're comparing to is not
itself, and that the value is not blank:
//check to make sure the slot is not already full
var selectedValue;
$('.ddl_slots').change(function() {
var ddl_current = $(this);
selectedValue = $(this).val();
$('.ddl_slots').each(function() {
if ($(this).val() == selectedValue $(this).val() !=
$
(this).attr('id') != ddl_current.attr('id'))
{
$(ddl_current).val();
alert(This slot is already selected for
another player);
}
});
});
