如何在URL更改时关闭弹出窗口？

window.onhashchange = function() {
  window.close();
};

// 或者

window.onpopstate = function() {
  window.close();
};

window.onhashchange = function() {
  window.opener.close();
};

// 打开弹出窗口时传递参数
var popupWindow = window.open('popup.html', 'popupWindow', 'width=400,height=300,location=no');

// 在URL更改时判断参数并关闭窗口
window.onhashchange = function() {
  if (window.location.search.indexOf('closePopup=true') !== -1) {
    popupWindow.close();
  }
};
