在两个窗口之间共享变量。棱角

$window.open

我有以下代码 WindowService 要打开新窗口(我们只打开一个窗口;如果需要更多窗口,则需要调整代码):

angular.module('myproject')
.service('WindowService', ['$window', '$interval', '$timeout', 
function ($window, $interval, $timeout) {

    var self = this;
    this.myOpenWindow = null;

    // opens a window and starts the wait-function
    this.openWindow = function (url, callbackFn) {
        // open the window
        self.myOpenWindow = $window.open(url);

        // Puts focus on the new window
        if (window.focus) {
            self.myOpenWindow.focus();
        }

        // check for response in opened window
        self.waitForResponse(callbackFn);
    };

    this.waitStarted = false;

    this.waitForResponse = function (callbackFn) {
        if (!self.waitStarted && self.myOpenWindow) {
            self.waitStarted = true;
            var intervalPeriod = 1000; // check once every second
            var waitHandler;
            waitHandler = $interval(function (index) {
                if (self.myOpenWindow.closed) {
                    // window was closed, commence cleaning operation
                    $interval.cancel(waitHandler);
                    waitHandler = $timeout(function () {
                        // re-initialize waitStarted so it can be used again
                        self.waitStarted = false;
                        // call callback-Function when the window is closed
                        if (callbackFn) {
                            callbackFn();
                        }
                    }, intervalPeriod);

                } else {
                    // window is still open, check if the observed variable is set 
                    if (self.myOpenWindow && self.myOpenWindow.response_message) {
                        var message = self.myOpenWindow.response_message;
                        // do what you want with the message
                        // ...
                        // afterwards close the window (or whatever)
                        if (self.myOpenWindow) {
                            self.myOpenWindow.close();
                        }
                    }
                }
            }, intervalPeriod);
        }
    };
}
]);

在打开的窗口中,您需要在某个地方设置全局变量,例如:

window['response_message'] = { 'result': 'Done' };
