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','');");
我使用这个代码弹出权限对话框.当用户点击允许Facebook重定向用户到我的应用程序在弹出窗口.我需要从弹出窗口发送代码到父窗口,然后在用户点击允许时关闭弹出窗口.
解决方法
告诉我,如果这是你正在寻找…
父窗口：
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>
