鼠标事件,由鼠标按下,鼠标弹起,鼠标经过,鼠标进入,鼠标退出几个事件组成 当在组件上鼠标按下的时候,会触发onmousedown事件 当在组件上鼠标弹起的时候,会触发onmouseup事件
当在组件上鼠标经过的时候,会触发onmousemove事件 当在组件上鼠标进入的时候,会触发onmouseover事件 当在组件上鼠标退出的时候,会触发onmouseout事件 注: 当鼠标进入一个组件的时候,onmousemove和onmouseover都会被触发,区别在于无论鼠标在组件上如何移动,onmouseover只会触发一次,onmousemove每次移动都会触发

键盘事件,由键盘按下keydown,键盘按下keypress,键盘弹起几个事件组成 当在组件上键盘按下的时候,会触发onkeydown事件 当在组件上键盘按下的时候,也会触发onkeypress事件 当在组件上键盘弹起的时候,会触发onkeyup事件 注: onkeypress 是当按下并弹起的组合动作,这个说法是错误的 都是用于表示键盘按下,onkeydown和onkeypress的区别在什么呢? onkeydown 可以获取所有键,除了打印键Prts 可以获取用户是否点击了修饰键 (ctrl,shift,alt) 不能判断输入的是大写还是小写 onkeypress 只能获取字符键 不能获取用户是否点击了修饰键 (ctrl,shift,alt) 可以判断输入的是大写还是小写
但是! 在不同的浏览器上,以上规则是不成立的。说这些都没有卵用,你无法控制用户到底使用哪种浏览器。 所以,只要记得keydown和keypress都表示点下了键。。。即可
