事件：绑定bind和解绑unbind：
$('选择器').bind('事件',function(){
// 操作
})
$('选择器').unbind('事件')
$('选择器').click(function(){
// 操作
})
mouseenter 鼠标进入
mouseleave 鼠标离开
hover = mouseenter + mouseleave
each 循环
$('选择器').each(function(index,dom){
$(this) // 循环出来的每个jq对象
// index 索引 dom dom对象
})
文档加载
window.onload = function () {
// 文档 图片 视频 音频 都加载完 执行一次 写多次会覆盖前面的
}
$(window).ready(function () {
// 文档 图片 视频 音频 都加载完 执行一次 能写多次
})
$(document).ready(function () {
// 文档 加载完 执行一次 能写多次
})
$(function () {
// 文档 加载完 执行一次 能写多次
})
事件冒泡
儿子父亲都绑定事件,触发儿子的事件,会一层层往上冒泡触发父辈的事件执行.

事件委托
利用了事件冒泡的原理,将事件委托给父亲,儿子触发事件时,执行父亲的事件.
// 事件委托
$('tbody').on('click','button',function () {
$(this).parents('tr').remove()
})
