在应用中有这样一个情况，
在A窗口中打开B窗口，在B窗口中操作完以后关闭B窗口，同时自动刷新A窗口
function closeWin(){
hasClosed = true;
window.opener.location="javascript:reloadPage();";
window.close();
}
function window.onbeforeunload(){
if(!hasClosed){
window.opener.location="javascript:reloadPage();";
}
}
</script>
上面的代码在关闭B窗口的时候会提示错误，说缺少Object,正确的代码如下：
function closeWin(){
hasClosed = true;
window.opener.location="javascript:reloadPage();";
window.opener=null;
window.close();
}
function window.onbeforeunload(){
if(!hasClosed){//如果已经执行了closeWin方法，则不执行本方法
window.opener.location="javascript:reloadPage();";
}
}
</script>
reloadPage方法如下:
function reloadPage() {
history.go(0);
document.execCommand("refresh")
document.location = document.location;
document.location.reload();
}
PS:由于需要支持正常关闭和强制关闭窗口时能捕捉到事件，用了全局变量hasClosed
==============================================
补充，在父窗口是frame的时候在刷新父窗口的时候会出现问题:
The page cannot be refreshed without resending the information
. 后修改如下:
window.opener.parent.document.frames.item('mainFrame').location.href = window.opener.location.href;
不需要执行自带的reload()方法,注意，不要再画蛇添足加上这一句:
window.opener.parent.document.frames.item('mainFrame').location.reload();
========================================================================================
function closeWin() {
hasClosed = true;
<%if(null != frame){%>
window.opener.parent.document.frames.item('mainFrame').location.href = window.opener.location.href;
<%}else{%>
window.opener.location = "javascript:reloadPage();";
<%}%>
//window.opener.top.mainFrame.location="javascript:reloadPage();";
//self.opener.frames.mainFrame.location.reload(true);
window.opener = null;
window.close();
}
function window.onbeforeunload(){
if (!hasClosed) {
<%if(null != frame){%>
window.opener.parent.document.frames.item('mainFrame').location.href = window.opener.location.href;
<%}else{%>
window.opener.location = "javascript:reloadPage();";
<%}%>
window.opener = null;
}
}
