JS正则表达

test - 判断字符串是否符合规定的正则
rep = /d+/;
rep.test("asdfoiklfasdf89asdfasdf")
# true

rep = /^d+$/;
rep.test("asdfoiklfasdf89asdfasdf")
# true

exec - 获取匹配的数据
rep = /d+/;
str = "wangshen_67_houyafa_20"
rep.exec(str)
# ["67"]

DOM

补充：

绑定事件的方法：

a. 直接标签绑定 onclick='xxx()'

b.先获取DOM对象，然后进行绑定

document.getElementById('Id').onclick

this, 当前触发事件的标签

c. 第三种绑定方式
