1>window.opener 的用法 在一般的用法中,只是用來解決關(guān)閉窗口時不提示彈出窗口,, 而對它更深層的了解一般比較少。其 實 window.opener是指調(diào)用window.open方法的窗口,。 2〉 在應(yīng)用中有這樣一個情況,,
在A窗口中打開B窗口,在B窗口中操作完以后關(guān)閉B窗口,同時自動刷新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窗口的時候會提示錯誤,,說缺少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)閉窗口時能捕捉到事件,用了全局變量hasClosed ============================================== 補(bǔ)充,,在父窗口是frame的時候在刷新父窗口的時候會出現(xiàn)問題: 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,,不要再畫蛇添足加上這一句: window.opener.parent.document.frames.item(‘mainFrame‘).location.reload(); ======================================================================================== 最后,為了同時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; } }
