string dialog_url = "http://www.facebook.com/dialog/oauth?client_id=" + app_id + "&redirect_uri=" + Server.UrlEncode(my_url) + "&scope=" + permission;
ClientScript.RegisterClientScriptBlock(typeof(Page), "key", "window.open('"+dialog_url+"','_parent','');");我将此代码用于弹出权限对话框。当用户单击允许Facebook将用户重定向到弹出窗口中的我的应用程序时。我需要将代码从弹出窗口发送到父窗口，然后在用户单击允许时关闭弹出窗口。
告诉我，如果这是您想要的...父窗口：
<html>
<head>
<script language="Javascript">
function showFBWindow(){
url = "allowfbchild.html"
newwindow=window.open(url,'name','height=200,width=150');
if (window.focus) {newwindow.focus()}
}
</script>
</head>
<body>
<input type="button" OnClick="showFBWindow()" value="Open FB" />
</body>
</html>
子窗口（allowfbchild.html）：
<html>
<head>
<script language="Javascript">
function redirectToFB(){
window.opener.location.href="http://wwww.facebook.com";
self.close();
}
</script>
</head>
<body>
Allow the user to view FB
<br/>Are you sure?
<input type="button" value="Ok" OnClick="redirectToFB()" />
</body>
</html>
在父页面中，按如下所示编写javascript
<script language="Javascript">
function popitup(url)
{
newwindow = window.open(url, "popwin", "width = 320, height = 210, resizable = no");
if (window.focus) { newwindow.focus() }
return false;
popwin.moveTo(0, 0);
}
</script>
<a href="" onclick="return popitup('myapppopup.aspx');return false;">`myapppopup</a>`
然后在弹出窗口中添加如下指向Facebook的链接
<a href="http://wwww.facebook.com" target="_blank" onclick="self.close();">facebook </a>
这是您的父窗口：
<script language="javascript">
function open_a_window()
{
var w = 200;
var h = 200;
var left = Number((screen.width/2)-(w/2));
var tops = Number((screen.height/2)-(h/2));
window.open("window_to_close.html", '', 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width='+w+', height='+h+', top='+tops+', left='+left);
return false;
}
</script>
<input type="button" onclick="return open_a_window();" value="Open New Window/Tab" />
这是您的子窗口：
<!DOCTYPE html>
<html>
<body onload="quitBox('quit');">
<h1>The window closer:</h1>
<input type="button" onclick="return quitBox('quit');" value="Close This Window/Tab" />
<script language="javascript">
function quitBox(cmd)
{
if (cmd=='quit')
{
var url = 'https://www.google.com';
window.opener.document.location.href = url;
open(location, '_self').close();
}
return false;
}
</script>
</body>
</html>
