window.open()总是在IE9上返回以true结尾的porpertie。这是我在Facebook上oAuth的代码:

 $(window).ready(function(){
        $("#linkFacebook").click(LoginFb);
    });
    var winInter;
    var win;
function LoginFb(){
        var linkFB = '@Url.Action("LogOn", "Facebookk")';
        win = window.open(linkFB, 'FB', 'toolbar=0,scrollbars=1,status=1,menubar=1,location=0,resizable=1,width=560,height=500');
       winInter = setInterval(checkWindow, 1000);
    }
    function checkWindow() 
    {
            try {
                if (win.closed) 
                {
                    clearTimeout(winInter);
                    window.location.href = "@Url.Action("Index", "User")";
                }
            }
            catch (e) 
            { }
   }

我在msdn上发现了这个bug: http://support.microsoft.com/kb/241109,但工作无效。因为window.opener.childOpen总是返回null。

我也尝试以下代码:

var WindowRef = null;

function openWindow(url, name, props) {
  if(WindowRef == null){
    WindowRef = window.open(url, name, props)
  }
  else{
    WindowRef.document.location = url
  }
  if (!WindowRef.opener) {
    WindowRef.opener = self;
  }
  WindowRef.focus();
  return WindowRef;
}

我在这里找到:window.open() returns undefined or null on 2nd call

编辑:http://www.myspace.com在IE上工作。我不明白他们是怎么做到的。

答案 0 :(得分:0)

open()是一种窗口方法,因此在非严格比较中它总是会评估为 true 。你想查看弹出窗口的closed属性,玩下面的内容(编辑,对不起,我第一次没有正确回答你的问题):

<script type="text/javascript">

var win;

function popWin(url) {
  if (win && !win.closed) {
    win.location.href = url;
  } else {
    win = window.open(url,'PopUp');
  }
  return win;
}

</script>

<button onclick="popWin('http://www.google.com');">Open new window</button>
<button onclick="alert(win && win.closed);">Check if closed</button>
<button onclick="win && win.close();">Just close</button>
<button onclick="win && win.close(); win = undefined;">
 Close and remove reference</button>

<button onclick="popWin('http://www.apple.com');">Change URL</button>
