兼容性

窗口位置离屏幕左偏移

var leftPos = (typeof window.screenLeft == "number") ? window.screenLeft : window.screenX; 浏览器兼容性问题可能不准确,建议用moveTo

窗口位置离屏幕上偏移

var topPos = (typeof window.screenTop == "number") ? window.screenTop : window.screenY; 

浏览器兼容性问题可能不准确,建议用moveTo

窗口定位到某位置

window.moveTo(0,0) Opera及IE7+默认禁用,且不适用于框架

窗口定位相对位置

window.moveBy(50,50) 

Opera及IE7+默认禁用,且不适用于框架

窗口调整大小1window.resizeTo(100,100)  窗口调用大小2window.resizeTBy(100,50)  页面视口大小        var pageWidth = window.innerWidth,
            pageHeight = window.innerHeight;   
        if (typeof pageWidth != "number"){
            if (document.compatMode == "CSS1Compat"){
                pageWidth= document.documentElement.clientWidth;
                pageHeight = document.documentElement.clientHeight;
            } else {
                pageWidth = document.body.clientWidth;
                pageHeight = document.body.clientHeight;
            }
        }$(window).width()

$(window).height() 元素距页面顶部偏移量       function getElementTop(element){
            var actualTop = element.offsetTop;
            var current = element.offsetParent;
            while (current !== null){        
                actualTop += current.offsetTop;
                current = current.offsetParent;
            }
            return actualTop;
        }$(element).offset().topjs为递归计算,只对可见元素有效元素距页面左侧偏移量        function getElementLeft(element){
            var actualLeft = element.offsetLeft;
            var current = element.offsetParent;
            while (current !== null){        
                actualLeft += current.offsetLeft;
                current = current.offsetParent;
            }
            return actualLeft;
        }

$(element).offset().left

js为递归计算,只对可见元素有效

元素在垂直方向上占用空间(含边框+内边距+滚动条)element.offsetHeight$(element).outerHeight(), 

元素在水平方向上占用空间(含边框+内边距+滚动条)

element.offsetWidth$(element).outerWidth(), 

元素在垂直方向上占用空间(不含边框,滚动条只含内边距)

element.clientHeight

$(element).height(),有区别,不含内边距

 

元素在水平方向上占用空间(不含边框,滚动条,只含内边距)

element.clientWidth

$(element).width(),有区别,不含内边距

 在没有滚动条时,元素内容总高度

element.scrollHeight

jquery未找到对应方法

var docHeight = Math.max(document.documentElement.scrollHeight,
document.documentElement.clientHeight);

在没有滚动条时,元素内容总宽度

element.scrollWidth

jquery未找到对应方法var docWidth = Math.max(document.documentElement.scrollWidth,
document.documentElement.clientWidth);已被滚动卷去的上方像素

var top = document.body.scrollTop | document.documentElement.scrollTop;

$(document).scrollTop()

可以用此方法滚动到指定位置

已被滚动卷去的左方像素

var left = document.body.scrollLeft | document.documentElement.scrollLeft;

$(document).scrollLeft()

可以用此方法滚动到指定位置

兼容所有浏览器,

取得元素矩阵,返回

元素左上角坐标距

视窗口的

left,top,right,bottom值
