Window size and scrolling
Posted by 机器人 on 24th 十二月 2008 in php/javascript
Finding the size of the browser window
function getWindowSize() { var myWidth = 0, myHeight = 0; if( typeof( window.innerWidth ) == 'number' ) { //Non-IE myWidth = window.innerWidth; myHeight = window.innerHeight; } else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) { //IE 6+ in 'standards compliant mode' myWidth = document.documentElement.clientWidth; myHeight = document.documentElement.clientHeight; } else if( document.body && ( document.body.clientWidth || document.body.clientHeight ) ) { //IE 4 compatible myWidth = document.body.clientWidth; myHeight = document.body.clientHeight; } window.alert( 'Width = ' + myWidth ); window.alert( 'Height = ' + myHeight ); }
Finding how far the window has been scrolled
function getScrollXY() { var scrOfX = 0, scrOfY = 0; if( typeof( window.pageYOffset ) == 'number' ) { //Netscape compliant scrOfY = window.pageYOffset; scrOfX = window.pageXOffset; } else if( document.body && ( document.body.scrollLeft || document.body.scrollTop ) ) { //DOM compliant scrOfY = document.body.scrollTop; scrOfX = document.body.scrollLeft; } else if( document.documentElement && ( document.documentElement.scrollLeft || document.documentElement.scrollTop ) ) { //IE6 standards compliant mode scrOfY = document.documentElement.scrollTop; scrOfX = document.documentElement.scrollLeft; } return [ scrOfX, scrOfY ]; }
