How do I pass jQuery object to function, and work with it?
I'm trying to build a function that accepts a JQuery object (a multi select drop down) and does stuff with it such as counting the non-zero options, etc, so I can limit the number of options the user can choose.
How do I refine the object's attributes, once inside the function? The event is a select onchange and function call: "checkOptionsLength( $('#selectID'), 20)"
function checkOptionsLength(obj,limit) {
// How many non zero length selected options are there?
// Outside of function this works > $('#selectID option[value!=]:selected').length ?
var count = $(obj) ...........; // Inside the function how do I get at this same value as above?
}
