Internet Explorer 中的 Window.screen 和多个监视器

Window.screen in Internet Explorer and more than one monitor

本文关键字：监视器 screen Explorer 中的 Window Internet      更新时间：2023-09-26

我有一个具有不同屏幕分辨率的双显示器设置，当我在Chrome中访问此页面时，它显示了两个屏幕的正确分辨率。但是IE只显示我的主屏幕的分辨率。它比在IE window.screen.availWidth中出现，window.screen.availHeight只返回主屏幕的值。我可以获取运行 Internet Explorer 的第二个屏幕的屏幕分辨率吗？

使用在 http://archive.cpradio.org/code/javascript/dual-monitors-and-windowopen/找到的古代代码

function FindLeftWindowBoundry()
{
	// In Internet Explorer window.screenLeft is the window's left boundry
	if (window.screenLeft)
	{
		return window.screenLeft;
	}
	
	// In Firefox window.screenX is the window's left boundry
	if (window.screenX)
		return window.screenX;
		
	return 0;
}
window.leftWindowBoundry = FindLeftWindowBoundry;
// Find Left Boundry of the Screen/Monitor
function FindLeftScreenBoundry()
{
	// Check if the window is off the primary monitor in a positive axis
	// X,Y                  X,Y                    S = Screen, W = Window
	// 0,0  ----------   1280,0  ----------
	//     |          |         |  ---     |
	//     |          |         | | W |    |
	//     |        S |         |  ---   S |
	//      ----------           ----------
	if (window.leftWindowBoundry() > window.screen.width)
	{
		return window.leftWindowBoundry() - (window.leftWindowBoundry() - window.screen.width);
	}
	
	// Check if the window is off the primary monitor in a negative axis
	// X,Y                  X,Y                    S = Screen, W = Window
	// 0,0  ----------  -1280,0  ----------
	//     |          |         |  ---     |
	//     |          |         | | W |    |
	//     |        S |         |  ---   S |
	//      ----------           ----------
	// This only works in Firefox at the moment due to a bug in Internet Explorer opening new windows into a negative axis
	// However, you can move opened windows into a negative axis as a workaround
	if (window.leftWindowBoundry() < 0 && window.leftWindowBoundry() > (window.screen.width * -1))
	{
		return (window.screen.width * -1);
	}
	
	// If neither of the above, the monitor is on the primary monitor whose's screen X should be 0
	return 0;
}
window.leftScreenBoundry = FindLeftScreenBoundry;
console.log(window.screen.width);
console.log(window.leftScreenBoundry());
console.log(window.screen.height);

我知道这并不多，但它至少可以让您评估客户端是否在双显示器集上以及该集有多宽。

IE唯一需要做的事情就是在所有蒙特人之间均匀地分配分辨率。

因此，它取总宽度并将其除以显示器数量。

我有 3 台显示器，2 台为 1920 x 1080，一台为 1600 x 900 用于我的测试，IE 给出的左侧位置为 1745 0 -1745，所以是的......IE总体上有些问题，但希望这个小片段对您有所帮助，或者其他人正在为IE制作半兼容代码。
