事件处理程序 - 转义/离开并跳过事件链

Question

如果你有几个事件处理程序，那么你怎么能离开/停止链？

$('input').keydown(function(e){
    console.log('first keydown');
});
$('input').keydown(function(e){
    console.log('second keydown');
    // leave/escape the event chain and skip the third keydown
});
$('input').keydown(function(e){
    console.log('third keydown');
});

Answer 1

stopImmediatePropagation应该可以解决问题：http://api.jquery.com/event.stopimmediatepropagation/

$('input').keydown(function(e){
    console.log('first keydown');
});
$('input').keydown(function(e){
    console.log('second keydown');
    // leave/escape the event chain and skip the third keydown
    e.stopImmediatePropagation();
});
$('input').keydown(function(e){
    //will not be logged
    console.log('third keydown');
});
