本文提供一段JavaScript代码，用于获取网页可见区域宽高、正文全文尺寸、滚动条位置、屏幕分辨率及可用工作区等关键属性。通过document.body、window.screen及window.innerHeight等对象，可快速查询页面布局与设备显示信息，适用于前端调试与响应式适配场景。

JavaScript获取网页尺寸与屏幕属性完整指南
具体实现代码如下所示：
function getInfo() {
{
var s = "";
s += " 网页可见区域宽：" + document.body.clientWidth + " ";
s += " 网页可见区域高：" + document.body.clientHeight + " ";
s += " 网页可见区域宽：" + document.body.offsetWidth + " (包括边线和滚动条的宽)" + " ";
s += " 网页可见区域高：" + document.body.offsetHeight + " (包括边线的宽)" + " ";
s += " 网页正文全文宽：" + document.body.scrollWidth + " ";
s += " 网页正文全文高：" + document.body.scrollHeight + " ";
s += " 网页被卷去的高(ff)：" + document.body.scrollTop + " ";
s += " 网页被卷去的高(ie)：" + document.documentElement.scrollTop + " ";
s += " 网页被卷去的左：" + document.body.scrollLeft + " ";
s += " 网页正文部分上：" + window.screenTop + " ";
s += " 网页正文部分左：" + window.screenLeft + " ";
s += " 屏幕分辨率的高：" + window.screen.height + " ";
s += " 屏幕分辨率的宽：" + window.screen.width + " ";
s += " 屏幕可用工作区高度：" + window.screen.availHeight + " ";
s += " 屏幕可用工作区宽度：" + window.screen.availWidth + " ";
s += " 你的屏幕设置是 " + window.screen.colorDepth + " 位彩色" + " ";
s += " 你的屏幕设置 " + window.screen.deviceXDPI + " 像素/英寸" + " ";
s += " window的页面可视部分实际高度(ff) " + window.innerHeight + " ";
alert(s);
};
