推荐答案

Binding: 将 handler 耦合到 element(s)，当 >event 发生在所述元素上.根据您要处理的事件类型，您可以使用不同的函数，例如 click(function) (alt: bind('click', function) 或 focus(function) (alt: bind('focus', function).

Binding: coupling an handler to an element(s), that will run when an event occurs on said element(s). Depending on what kind of event you want to handle you'd use different functions like click(function) (alt: bind('click', function) or focus(function) (alt: bind('focus', function).

解除绑定:将处理程序与元素解耦，以便当事件发生时，处理程序函数不会运行时间更长.解除绑定总是一样的；unbind('click', function) 取消绑定某个处理程序，unbind('click') 取消绑定所有点击处理程序，以及 unbind()> 解除绑定所有处理程序.当然，您可以将 click 替换为其他类型的事件.

Unbinding: de-coupling of an handler from an element(s), so that when an event occurs the handler function will no longer run. Unbinding is always the same; unbind('click', function) to unbind a certain handler, unbind('click') to unbind ALL click handlers, and unbind() to unbind ALL handlers. You can substitute click for other types of events of course.
