特殊1、
document.body.scrollTop总为0的解决方法
var scrollPos;
if (typeof window.pageYOffset != 'undefined') {
scrollPos = window.pageYOffset;
}
else if (typeof document.compatMode != 'undefined' &&
document.compatMode != 'BackCompat') {
scrollPos = document.documentElement.scrollTop;
}
else if (typeof document.body != 'undefined') {
scrollPos = document.body.scrollTop;
}
alert(scrollPos );
特殊2、
网页正文全文宽:"+ document.body.scrollWidth;
网页正文全文高:"+ document.body.scrollHeight;
以上函数有时获取不了,就用一下方法。
var xScroll, yScroll;
if (window.innerHeight && window.scrollMaxY)
{
xScroll = document.body.scrollWidth;
yScroll = window.innerHeight + window.scrollMaxY;
} else if (document.body.scrollHeight > document.body.offsetHeight){ // all but Explorer Mac
xScroll = document.body.scrollWidth;
yScroll = document.body.scrollHeight;
} else
{ // Explorer Mac...would also work in Explorer 6 Strict, Mozilla and Safari
xScroll = document.body.offsetWidth;
yScroll = document.body.offsetHeight;
}
