ps:前言-最近再研究上拉加载与下拉刷新，涉及到文档高、可视区高等。。
本人测试ie,FF,chrome用document.documentElement.clientHeight都能取得高度和jquery 中的$(window).height();一样的值
文档的高度
document.body.clientHeight||document.documentElement.clientHeight,
文档滚动条位置
document.body.scrollTop||document.documentElement.scrollTop
但没有定义W3C标准会有问题
var dd = document.body || document.documentElement;
var h1 = Math.max(dd.clientHeight,db.clientHeight);var h2 = Math.max(dd.scrollHeight,db.scrollHeight);var objH = Math.max(h1,h2);
===============测试总结==================
has w3c
chrome:
- document文档高度
($(document).height())==document.body.clientHeight;
document.documentElement.scrollHeight==document.body.scrollHeight
- 可视高度
($(window).height())==document.documentElement.clientHeight;
scrollTop==document.body.scrollTop
firefox:
document文档高度==document.body.clientHeight;
document.documentElement.scrollHeight==document.body.scrollHeight
可视高度==document.documentElement.clientHeight;
scrollTop==document.documentElement.scrollTop;
ie:
document文档高度==document.body.clientHeight;
document.documentElement.scrollHeight==document.body.scrollHeight
可视高度==document.documentElement.clientHeight;
scrollTop==document.documentElement.scrollTop;
no w3c
chrome:
document文档高度($(document).height())!=document.body.clientHeight;
document文档高度==document.documentElement.clientHeight;
document.documentElement.scrollHeight==document.body.scrollHeight
可视高度($(window).height())==document.documentElement.clientHeight;等于文档高度
可视高度为document.body.clientHeight;
scrollTop==document.body.scrollTop
firefox:
document文档高度($(document).height())!=document.body.clientHeight;
document文档高度==document.documentElement.clientHeight;
document.documentElement.scrollHeight==document.body.scrollHeight
可视高度($(window).height())==document.documentElement.clientHeight;等于文档高度
可视高度为document.body.clientHeight;
scrollTop==document.body.scrollTop
ie
document文档高度==document.body.scrollHeight;
可视高度==document.body.clientHeight;
document.documentElement.scrollHeight
document.documentElement.clientHeight==0
scrollTop==document.body.scrollTop
has w3c兼容
文档高(推荐scrollHeight,document.body.clientHeight || document.documentElement.clientHeight;)
--------------------------------------兼容ie firefox chrome--------------------------------
****文档高
document.documentElement.scrollHeight||document.body.scrollHeight;(注意)
可视高
document.documentElement.clientHeight || document.body.clientHeight
scrollTop==document.documentElement.scrollTop||document.body.scrollTop;```
-------------------------------------------------------------------------------------------
####no w3c兼容
文档高document.documentElement.clientHeight || document.body.scrollHeight;
可视高document.body.clientHeight
scrollTop==document.documentElement.scrollTop||document.body.scrollTop;
