页面总宽度：document.body.scrollWidth;
页面总高度：document.body.scrollHeight;
Chrome页面位置：document.body.scrollTop; document.body.scrollLeft;
Chrome标准页面可视区域：document.documentElement.clientWidth; document.documentElement.clientHeight;
Chrome特殊页面可视区域：document.body.clientWidth; document.body.clientHeight;
IE标准页面位置：document.documentElement.scrollTop; document.documentElement.scrollLeft;
IE标准页面可视区域：document.documentElement.clientWidth; document.documentElement.clientHeight;
IE特殊页面位置：document.body.scrollTop; document.body.scrollLeft;
IE特殊页面可视区域：document.body.clientWidth; document.body.clientHeight;
JS代码如下：
function getSize() {
var obj = new Object();
obj.allWidth = document.body.scrollWidth;
obj.allHeight = document.body.scrollHeight;
if (-[1, ]) { //非IE
obj.top = document.body.scrollTop;
obj.left = document.body.scrollLeft;
if (document.compatMode === ‘CSS1Compat’) {
obj.width = document.documentElement.clientWidth;
obj.height = document.documentElement.clientHeight;
}
else {
obj.width = document.body.clientWidth;
obj.height = document.body.clientHeight;
}
} else {
if (document.compatMode === ‘CSS1Compat’) {
obj.width = document.documentElement.clientWidth;
obj.height = document.documentElement.clientHeight;
obj.top = document.documentElement.scrollTop;
obj.left = document.documentElement.scrollLeft;
}
else {
obj.width = document.body.clientWidth;
obj.height = document.body.clientHeight;
obj.top = document.body.scrollTop;
obj.left = document.body.scrollLeft;
}
}
alert(obj.top);
alert(obj.left);
alert(obj.width);
alert(obj.height);
return obj;
}
注：发现博客园首页的HTML文档类型为：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
为什么和随笔展示页不一样呢？
