你怎么解开一些事件呢？

Question

I have a few things like this...

$('body').on('keyup', function(e){if(e.which === 32){//do stuff}})

I need to disable some of these events at times but not all of them.

$('body').off('keyup') just turns them all off.

Answer 1

命名空间...

$('body').on('keyup.some_name', function(e){if(e.which === 32){//do stuff}})

---

$('body').off('keyup.some_name')

Answer 2

var onKeyUp = function(e){if(e.which === 32){//do stuff}}

$('body').on('keyup', onKeyUp);

// later...

$('body').off('keyup', onKeyUp);
