JQuery :: Null - Undefined - Empty - Drop Down Option Is Selected In A Drop Down List ?
Oct 25, 2011I 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.

View 9 Replies View RelatedJQuery :: Limit If A Value Can Be Selected In A Drop Down List (select) Based On Other List
Jun 9, 2009I 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.

Hide Select Item In A Drop-down Box With An Asterisk
Apr 25, 2006I have a drop down box in HTML using SELECT and OPTION tags:
<select title="Choose a number" onchange="obscure()" name="Digit1"

<OPTION VALUE="0"> 0</OPTION>
<OPTION VALUE="1"> 1</OPTION>
