行不行 How can I check that a popup window is still open before attempting to close it?You can check to see if the window has been opened then subsequently closed with: <script language="JavaScript"><!-- var windowHandle = null;function openWindow() { windowHandle = window.open('http://www.irt.org/','windowName','height=200,width=200'); if (!windowHandle.closed) window.closed = false; }function closeWindow() { if (windowHandle != null) { if (windowHandle.closed) { // already opened and closed } else { windowHandle.closed = true; windowHandle.close(); } } else // not yet opened } //--></script> Micke Kazarnowicz writes: The original didn't work (generated error messages in IE 5.0) and worked only once in Netscape 4.7.

我想开一个新窗口
然后再由原来的网页控制新窗口
但在控制前就要肯定新窗口还存在
所以现在的问题是怎么检查一个新的窗口是否存在
你用的方法和我一样的
这样只是在窗口存在时才能用的
当窗口不存在时
if (!WinId.opener) WinId.opener = self;
在检查WinId.opener时就会出错
错误是远端伺服器不存在或无法使用
function newWindow(file,window) {
msgWindow=open(file,window,'resizable=no,width=200,height=200');
if (msgWindow.opener == null) msgWindow.opener = self;
}

我已经知道问题出在哪里了
我和你的程序都没错
上面的文章说的也没错
搞了几天
原来大家都没错
错的是我自己用vb写的测试程序
他引用的是ie以前的版本
怪不得我按上面的文章去写一直出错
