我正在以这种方式打开 Facebook 共享的子窗口：
window.open(sharingUrl,'','toolbar=0,status=0,width=626,height=436');
当用户单击共享或关闭时，窗口会自动关闭...
有没有办法为这些事件添加监听器？
如果您在调用
window.open()setInterval()window.closedvar child = window.open('http://google.com','','toolbar=0,status=0,width=626,height=436');
var timer = setInterval(checkChild, 500);
function checkChild() {
if (child.closed) {
alert("Child window closed");
clearInterval(timer);
}
}
其他人注意：如果您曾经处于可以控制子窗口中的html的情况，您可以使用onbeforeunload事件并提醒父窗口。
为了将来的参考，我想分享另一个不需要的解决方案
setIntervalvar child = window.open('http://google.com','','toolbar=0,status=0,width=626,height=436');
child.onunload = function(){ console.log('Child window closed'); };
var child = window.open('http://google.com','','toolbar=0,status=0,width=626,height=436');
// Called even when loading and unloading.
child.onunload = function(){
// What matters here
setTimeout(function(){
if (child.closed) {
console.log('Child window closed');
}
}, 300);
};
这会很好用
