复选框上的.click和.change之间的区别 [英] What the difference between .click and .change on a checkbox

问题描述

我正在环顾四周，为一个复选框添加一个事件，我会认为人们会使用 .change 设置一个更改事件，但我发现，使用 .click

I was looking around to add an event to a checkbox and I would have thought people would use .change to set up a change event but instead I found that people are using .click

有什么原因吗？他们似乎都与点击事件和键盘更改工作正常。我错过了什么？

Is there a reason for this? They both seem to work fine both with clicked events and with keyboard changes. Am I missing something?

推荐答案

onchange IE仅在复选框失去焦点时触发。所以如果你tab到它，击中空间几次，选项卡，你只会得到一个 onchange 事件，但几个 onclick 事件。

onchange in IE only fires when the checkbox loses focus. So if you tab to it, hit space a few times, tab out, you'll only get one onchange event, but several onclick events.

注意：这是一个非常，非常，非常罕见的时候，当IE的行为是正确的。

Note: this is one of the very, very, very rare times when IE's behavior is correct (according to spec) and other browsers are wrong.
