我们如何通过javascript窗口打开一个弹出窗口的中心。打开功能上的屏幕中心变量，以当前选择的屏幕分辨率?

公认的解决方案是无法工作的，除非浏览器占据全屏，
这似乎总是有效的
const popupCenterScreen = (url, title, w, h, focus) => {
const top = (screen.height - h) / 4, left = (screen.width - w) / 2;
const popup = window.open(url, title, `scrollbars=yes,width=${w},height=${h},top=${top},left=${left}`);
if (focus === true && window.focus) popup.focus();
return popup;
}
Impl:
some.function.call({data: ''})
.then(result =>
popupCenterScreen(
result.data.url,
result.data.title,
result.data.width,
result.data.height,
true));

它在Firefox中运行得非常好。 只需将顶部变量更改为任何其他名称，然后再试一次
var w = 200;
var h = 200;
var left = Number((screen.width/2)-(w/2));
var tops = Number((screen.height/2)-(h/2));
window.open("templates/sales/index.php?go=new_sale", '', 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width='+w+', height='+h+', top='+tops+', left='+left);
我的ES6 JavaScript版本。 工作良好的铬和铬双屏幕设置。
function openCenteredWindow({url, width, height}) {
const pos = {
x: (screen.width / 2) - (width / 2),
y: (screen.height/2) - (height / 2)
};
const features = `width=${width} height=${height} left=${pos.x} top=${pos.y}`;
return window.open(url, '_blank', features);
}
例子
openCenteredWindow({
url: 'https://stackoverflow.com/',
width: 500,
height: 600
}).focus();

由于在多显示器设置中确定当前屏幕中心的复杂性，一个更简单的选择是将弹出窗口置于父窗口的中央。简单地将父窗口作为另一个参数传递:
function popupWindow(url, windowName, win, w, h) {
const y = win.top.outerHeight / 2 + win.top.screenY - ( h / 2);
const x = win.top.outerWidth / 2 + win.top.screenX - ( w / 2);
return win.open(url, windowName, `toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width=${w}, height=${h}, top=${y}, left=${x}`);
}
实现:
popupWindow('google.com', 'test', window, 200, 100);
.center { 左:50%; max-width: 350 px; 填充:15 px; text-align:中心; 位置:相对; 变换:translateX (-50%); -moz-transform: translateX (-50%); -webkit-transform: translateX (-50%); -ms-transform: translateX (-50%); -o-transform: translateX (-50%); ｝
