How to pass parameter to $.keyup() ？

Question

I want to do something like :

function validateBody($obj)
{

}

$ojb.keyup(validateBody($ojb));

How to do it the right way?

Answer 1

I believe this is what you want, correct?

function validateBody(obj, number) {
  //do something...
}

$ojb.keyup(function() {
  var someNumber = getNumberFromAlgorithm();
  validateBody($(this), someNumber)
});

Answer 2

This will do what you are looking for:

function validateBody(e) {
    var $obj = e.data.obj;

    // do something
}

$ojb.bind('keyup', { obj: $ojb }, validateBody);

Check out the documentation on event.data and bind
