Question

我需要检查一个窗口是否关闭。这是我的例子，

我通过调用此函数

打开了一个新窗口

$scope.openwind= function(){
    $scope.popupWindow = $window.open("index.html#/channelintegration", "SOme Title", 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no');
}

然后我一直在检查打开的窗口（popupWindow）是否关闭，通过单击按钮调用以下功能，

$scope.checkmywindow=function(){
    console.log($scope.popupWindow);
    console.log($scope.popupWindow.closed);
}

现在，我需要检查窗口（popupWindow）是否关闭，没有按钮触发器。

请帮忙...谢谢..

您可以通过在范围变量中使用window is opened or not函数来检查window.open是否正确，并使用范围进行检查。

$scope.openwind= function(){
    $scope.popupWindow = $window.open("index.html#/channelintegration", "SOme Title", 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no');
}

$scope.closewind= function(){
    if ($scope.popupWindow) {
          $scope.popupWindow.close();
      }
    // code for closing goes here

}

$scope.checkmywindow=function(){
    if (!$scope.popupWindow) {
        document.getElementById("msg").innerHTML = "'$scope.popupWindow' has never been opened!";
    } else {
        if ($scope.popupWindow.closed) {
            document.getElementById("msg").innerHTML = "'$scope.popupWindow' has been closed!";
        } else {
            document.getElementById("msg").innerHTML = "'$scope.popupWindow' has Opened!";
        }
    }
}

@Sravan，谢谢你的回答..这对于做更多事情确实有很大的帮助..现在我使用下面的代码自动检查窗口是否关闭，使用角度的$ interval服务。这将根据窗口的当前状态（popupWindow）自动每秒更新一个范围变量（windowstatus）..

AND tsdate BETWEEN TO_DATE('09-oct-2016', 'dd-MON-yyyy') AND TO_DATE('22-oct-2016', 'dd-MON-yyyy')
