- js 和 jquery 获取页面和滚动条的高度
- //页面位置及窗口大小
- function GetPageSize() {
- var scrW, scrH;
- if(window.innerHeight
- && window.scrollMaxY)
- { // Mozilla
- scrW =
- window.innerWidth + window.scrollMaxX;

- jquery
- 获取浏览器显示区域的高度 :
- $(window).height();
- 获取浏览器显示区域的宽度 :$(window).width();
- 获取页面的文档高度
- :$(document).height();
- 获取页面的文档宽度 :$(document).width();
- 获取滚动条到顶部的垂直高度
- :$(document).scrollTop();
- 获取滚动条到左边的垂直宽度 :$(document).scrollLeft();
- 计算元素位置和偏移量
- offset方法是一个很有用的方法,它返回包装集中第一个元素的偏移信息。默认情况下是相对body的偏移信息。结果包含 top和left两个属性。
- offset(options, results)
- options.relativeTo 指定相对计
- 算偏移位置的祖先元素。这个元素应该是relative或absolute定位。省略则相对body。
- options.scroll 是否把
- 滚动条计算在内,默认TRUE
- options.padding 是否把padding计算在内,默认false
- options.margin
- 是否把margin计算在内,默认true
- options.border 是否把边框计算在内,默认true
