怎么拿到当前页面的锚点

dom有个hashchange事件

window.addeventlistener(''hashchange",function(e){

console.log(window.location.hash);  //拿到锚点值

//http://www.baidu.com:8080/aaa/1.html/?name=zhangsan#sex

//hostname:www.baidu.com

//host:www.baidu.com:8080

//.port  :8080

//.search ？name=张三

//pathname:/aaa/1.html

})
