AngularJS-如何在Chrome应用中打印模态流行DIV内容

我正在创建一个Chrome应用程序。我必须使用Angular.js打印模态弹出窗口的DIV内容。在HTML页面上，它工作正常，但是在Chrome App中，document.open()和document.write()不起作用。等待最佳结果？请在下面找到代码。

            $('.onPrint').css('display', 'inline-block');
        }
    });
</script>

在不使用 UI Bootstrap

的情况下更新了解决方案

使用@Media打印在打印时更改设计。

检查下面的演示： -

(function () {
    'use strict';
    var UnitApp = angular.module("UnitApp", []);
    UnitApp.controller("UnitController", function ($scope) {
        
        $scope.friends = [
            { name: 'John', id: 1 },
            { name: 'Jessie', id: 2 },
            { name: 'Johanna', id: 3 },
            { name: 'Joy', id: 4 }
        ];
        $scope.onprint = function () { 
            window.print();
        }       
    });
})();

请在下面找到工作演示

使用了UI Bootstrap模态弹出窗口，该弹出窗口使用了角度的控件。

angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('ModalDemoCtrl', function ($scope, $uibModal, $log) {
    $scope.animationsEnabled = true;
    $scope.friends = [
             { name: 'John', id: 1 },
             { name: 'Jessie', id: 2 },
             { name: 'Johanna', id: 3 },
             { name: 'Joy', id: 4 }
    ];
    $scope.print = function () {
        window.print();
    }
    $scope.open = function (size) {
        var modalInstance = $uibModal.open({
            animation: $scope.animationsEnabled,
            templateUrl: 'myModalContent.html',
            controller: 'ModalInstanceCtrl',
            size: size,
            resolve: {
                items: function () {
                    return $scope.friends;
                }
            }
        });
        modalInstance.result.then(function () {
        }, function () {
            $log.info('Modal dismissed at: ' + new Date());
        });
    };
});
// Please note that $modalInstance represents a modal window (instance) dependency.
// It is not the same as the $uibModal service used above.
angular.module('ui.bootstrap.demo').controller('ModalInstanceCtrl', function ($scope, $modalInstance, items) {
    $scope.friends = items;
    $scope.print = function () {
        window.print();
    }
    $scope.ok = function () {
        $modalInstance.close();
    };
    $scope.cancel = function () {
        $modalInstance.dismiss('cancel');
    };
});
