带有toggle()的复选框会打破选中/未选中状态 [英] Checkbox with toggle() breaking the checked/unchecked state

问题描述

有人能散些光吗?

为什么此.toggle()打破了复选框的选中/未选中状态?

Why this .toggle() is breaking the checked/unchecked state of a checkbox?

$('#checkbox').toggle(function(){},function(){});​

当我想到的时候，它什么也没做.

when I think, it's just doing nothing.

_{这取自对此 answer}

推荐答案

toggle()用两个回调调用会在目标元素上添加一个click事件.该事件将在偶数点击时执行第一个回调；第二个是奇数.

toggle() called with two callbacks adds a click event on the targeted element. The event will execute the first callback on even clicks; the second one on odd ones.

而且，这就是为什么改变行为的原因，根据手册:

Also, and this is why it changes the behaviour, according to the manual:

该实现还会在事件上调用.preventDefault()，因此，如果在元素上调用了.toggle()，则不会跟随链接，也不会单击按钮.

The implementation also calls .preventDefault() on the event, so links will not be followed and buttons will not be clicked if .toggle() has been called on the element.
