Question

I am creating a pop-up window. After I am finished with the work on child (pop up) window and click close button, I need to call a JavaScript function of the parent window. How can I achieve this? I am not creating the child window myself but displaying the contents of some other URL.

Answer 1

我不认为你可以做一件事,因为当《URL》来自不同领域时,你可以拿文件本身。但是,你可以污染并检查窗户的“封闭”财产:

var w = window.open("http://what.ever.com", "OtherWindow");
setTimeout(function() {
  if (w.closed) {
    // code that you want to run when window closes
  }
  else
    setTimeout(arguments.callee, 100);
}, 100);

如果你希望:

var w = window.open("http://what.ever.com", "OtherWindow");
var interval = setInterval(function() {
  if (w.closed) {
    // do stuff
    cancelInterval(interval);
  }
}, 100);

Answer 2

如果儿童窗口不是源于与父母窗口相同的域名,则由于same origin policy而重新锁定。这样做是为了防止交叉描述攻击。

Answer 3

Don。仅改进点代码,删除<条码>标记。 Vote for Pointy.

var w = window.open("http://what.ever.com", "OtherWindow");
setTimeout(function timeout() {
  if (w.closed) {
    // code that you want to run when window closes
  }
  else
    setTimeout(timeout, 100);
}, 100);
