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);

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));

你可以使用css来做到这一点，只要给元素下面的属性被放置在弹出窗口的中心

element{

position:fixed;
left: 50%;
top: 50%;
-ms-transform: translate(-50%,-50%);
-moz-transform:translate(-50%,-50%);
-webkit-transform: translate(-50%,-50%);
 transform: translate(-50%,-50%);

}

试着这样做:

function popupwindow(url, title, w, h) {
  var left = (screen.width/2)-(w/2);
  var top = (screen.height/2)-(h/2);
  return window.open(url, title, 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width='+w+', height='+h+', top='+top+', left='+left);
} 

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);
