JS获取屏幕分辨率以及当前对象大小等
1 <script type="text/javascript"> 2 function getInfo(){ 3 var s = ""; 4 s += " 网页可见区域宽:"+ document.body.clientWidth+"\n"; 5 s += " 网页可见区域高:"+ document.body.clientHeight+"\n"; 6 s += " 网页可见区域宽:"+ document.body.offsetWidth + " (包括边线和滚动条的宽)"+"\n"; 7 s += " 网页可见区域高:"+ document.body.offsetHeight + " (包括边线的宽)"+"\n"; 8 s += " 网页正文全文宽:"+ document.body.scrollWidth+"\n"; 9 s += " 网页正文全文高:"+ document.body.scrollHeight+"\n"; 10 s += " 网页被卷去的高(ff):"+ document.body.scrollTop+"\n"; 11 s += " 网页被卷去的高(ie):"+ document.documentElement.scrollTop+"\n"; 12 s += " 网页被卷去的左:"+ document.body.scrollLeft+"\n"; 13 s += " 网页正文部分上:"+ window.screenTop+"\n"; 14 s += " 网页正文部分左:"+ window.screenLeft+"\n"; 15 s += " 屏幕分辨率的高:"+ window.screen.height+"\n"; 16 s += " 屏幕分辨率的宽:"+ window.screen.width+"\n"; 17 s += " 屏幕可用工作区高度:"+ window.screen.availHeight+"\n"; 18 s += " 屏幕可用工作区宽度:"+ window.screen.availWidth+"\n"; 19 s += " 你的屏幕设置是 "+ window.screen.colorDepth +" 位彩色"+"\n"; 20 s += " 你的屏幕设置 "+ window.screen.deviceXDPI +" 像素/英寸"+"\n"; 21 alert (s); 22 } 23 getInfo(); 24 </script>
扩展,设置界面所有输入框宽度的语法如下:
1 <script type="text/javascript" > 2 //根据屏幕分辨率设置所有文本框的宽度 3 var width = window.screen.width; //分辨率宽度 4 var inputWidth = (width - 250) / 2 * 0.90; //场景是一个table里面有4列,分别是列名称1,列值1,列名称2,列值2;250是菜单栏的宽度,除以2就是每个文本框所在td(列值2)的宽度 5 var doms = document.getElementsByTagName("input"); 6 if (doms != undefined && doms != null && doms.length > 0) { 7 for (var i = 0; i < doms.length; i++) { 8 doms[i].style.width = inputWidth + "px"; 9 } 10 } 11 </script>
