子窗口关闭时的回调函数调用

单击按钮时，我打开了子窗口。在此窗口中，我将一些数据保存到数据库中。
我想在子窗口关闭时调用另一个java脚本函数。

I have open child window when click on button.In this window I have save some data into database. I want to call another java script function when child window is close.

我已经尝试过这个在javascript 解决方案中将回调函数设置为新窗口，但它无效。

I have already tried this Set a callback function to a new window in javascript solution but it is not working.

那么请告诉我如何调用回调函数？

So please tell me how to call callback function ?

我成功保存后还从子窗口设置了一个隐藏字段。我已经尝试在更新之前提醒这个隐藏值但是它的警报。

I have also set one hidden field from child window after successfully save.I have try to alert this hidden value but its alert before updating.

function open_child()
{
    $("#child_succ").val(0);
    alert($("#child_succ").val());
    window.open("child.php","Ratting","width=550,height=300,left=150,top=200,toolbar=1,status=1");
    alert($("child_succ").val());
}

回调功能

function test()
{
    alert("called from child window");
}
