function getScreenWidth()
{
   var de = document.body.parentNode;
   var db = document.body;
   if(window.opera)return db.clientWidth;
   if (document.compatMode=='CSS1Compat') return de.clientWidth;
   else return db.clientWidth;
}

找到屏幕分辨率的简单步骤是:

复制

`My screen resolution is: ${window.screen.width} * ${window.screen.height}`

粘贴到浏览器控制台 回车

var width = screen.width;
var height = screen.height;

function getScreenWidth()
{
   var de = document.body.parentNode;
   var db = document.body;
   if(window.opera)return db.clientWidth;
   if (document.compatMode=='CSS1Compat') return de.clientWidth;
   else return db.clientWidth;
}

使用jQuery，你可以做到:

$(window).width()
$(window).height()

只是为了将来参考:

function getscreenresolution()
{
    window.alert("Your screen resolution is: " + screen.height + 'x' + screen.width);
}
