在應(yīng)用中有這樣一個(gè)情況，
在A窗口中打開(kāi)B窗口，在B窗口中操作完以后關(guān)閉B窗口，同時(shí)自動(dòng)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>
上面的代碼在關(guān)閉B窗口的時(shí)候會(huì)提示錯(cuò)誤，說(shuō)缺少Object,正確的代碼如下：
function closeWin(){
        hasClosed = true;
        window.opener.location="javascript:reloadPage();";
        window.opener=null;
        window.close();
    }
    function window.onbeforeunload(){
        if(!hasClosed){//如果已經(jīng)執(zhí)行了closeWin方法，則不執(zhí)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:由于需要支持正常關(guān)閉和強(qiáng)制關(guān)閉窗口時(shí)能捕捉到事件，用了全局變量hasClosed

==============================================

補(bǔ)充，在父窗口是frame的時(shí)候在刷新父窗口的時(shí)候會(huì)出現(xiàn)問(wèn)題:

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;
不需要執(zhí)行自帶的reload()方法,注意，不要再畫(huà)蛇添足加上這一句:

window.opener.parent.document.frames.item(‘mainFrame‘).location.reload();

========================================================================================
最后，為了同時(shí)支持刷新普通父窗口和frame父窗口，代碼如下:
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;
        }
    }
