function getPageSize(){ 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; } var windowWidth, windowHeight; if (self.innerHeight) { // all except Explorer windowWidth = self.innerWidth; windowHeight = self.innerHeight; } else if (document.documentElement && document.documentElement.clientHeight) { // Explorer 6 Strict Mode windowWidth = document.documentElement.clientWidth; windowHeight = document.documentElement.clientHeight; } else if (document.body) { // other Explorers windowWidth = document.body.clientWidth; windowHeight = document.body.clientHeight; } // for small pages with total height less then height of the viewport if(yScroll < windowHeight){ pageHeight = windowHeight; } else { pageHeight = yScroll; } // for small pages with total width less then width of the viewport if(xScroll < windowWidth){ pageWidth = windowWidth; } else { pageWidth = xScroll; } arrayPageSize = new Array(pageWidth,pageHeight,windowWidth,windowHeight) return arrayPageSize; } 有幸找到了你的这个东东,帮我解决了问题,不过仔细看了下,好象大大的有点问题,参数值和名称上看好象有点对不上号哦. // for small pages with total height less then height of the viewport if(yScroll < windowHeight){ pageHeight = yScroll; } else { pageHeight = windowHeight; } // for small pages with total width less then width of the viewport if(xScroll < windowWidth){ pageWidth = xScroll; } else { pageWidth = windowWidth; }
