jquery - setting a limit of items, that can be dragged into a list -

-

I have these two lists, out of which I can move items from jquery UI to each other and to AJAX I can add lists together. If an item is drawn, a message is generated in a php file and then appears on the screen. Now I want to put ten items in the correct list for example, at max. It would be great that it would be possible with jquery, that if the list already has ten items and you go and drag it to the eleventh, then if the item will become extinct, maybe a bit effekt. I think reading DB in a PHP file might be probably if there are already ten items, and so on. But I do not have any idea at present, if and if that way, jquery will support such behavior. Can you give me some advice?

Greetings, Mashak

By the example, you can: 

  $ ("# draggable"). Draggable (); $ ("# Droppable") droppable ({drop: function} (if ($ ("# draggable"). Children () Length; 10) Return;}});

Anything in that line.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
