如果打开，则window.open()在IE11中返回null [英] window.open() returns null in IE11 if opening
问题描述
在具有默认设置的Windows 10上的IE中，如果我从本地计算机上的页面或本地网络上的服务器对外部Internet站点执行window.open()，则得到null.
In IE on Windows 10 with default settings, if I perform a window.open() against an external internet site from a page on my local machine or a server on my local network, I get null.
请参阅下面的我的副本.在Windows 7或Windows Chrome浏览器中的IE中不会发生这种情况.
See my repro below. This doesn't happen in IE on Windows 7 or Google Chrome.
有趣的是，如果我为Intranet区域打开启用保护模式"(以使Intranet区域和Internet区域中的保护模式相同)，那么问题就消失了.但是，我需要它在不要求用户执行此操作的情况下工作.
Interestingly, if I turn on "Enable Protected Mode" for the Intranet Zone (so that Protected Mode are the same in the Intranet Zone and Internet Zone), then the problem goes away. However, I need this to work without requiring users to do this.
我还没有找到任何清晰的Microsoft文档来解释此行为.我在EdgeHTML问题上针对此问题提出了问题网站，但希望了解SO社区是否对此有任何了解.
I haven't found any clear Microsoft documentation that explains this behavior. I raised an issue on this on the EdgeHTML issues site, but wanted to see if the community on SO has any insight into why this is happening.
谢谢！

推荐答案
似乎保护模式不允许在当前域之外打开新窗口，因此您可以尝试在空白页之后打开该窗口更新位置.
It seems that protected mode doesn't allow to open new window outside of the current domain, so you can try to open the window with a blank page and after update the location.
<script>
var popupWindow = null;
function openWindow() {
popupWindow = window.open('', '_blank', 'left=100;top=100;height=100;width=100');
popupWindow.location = 'http://microsoft.com';
}
function checkWindowStatus() {
if (popupWindow) {
document.getElementById('status').innerHTML += '- Truthy reference. Closed? ' + popupWindow.closed + '</br>';
} else {
document.getElementById('status').innerHTML += '- Falsy reference: ' + popupWindow + '</br>';
}
}
</script>
