Closing a Browser Window with JavaScript3 mins readLast updated: 4 May 2023145 viewsJavaScript Course With Certification: Unlocking the Power of JavaScriptby Mrinal Bhattacharya1000Start Learning JavaScript Course With Certification: Unlocking the Power of JavaScriptStart Learning OverviewSometimes it is needed to close a browser window that we opened, we can do this using javascript but due to security reasons, we can close only those browser windows that we opened using javascript script and not the windows that are opened by the user.IntroductionThe only thing to be noted here is that we can close only those browser windows that we opened using our javascript script/code. Today's security standards do not allow closing the browser windows (using javascript script) that are opened by the user.The below steps demonstrate the approach in which we open a URL using javascript so that it can be closed using the script :Opening a new browser window using the javascript open method:First, it is needed to open a new browser window using the window.open() method. It takes two arguments, the first argument is the current URL which we will access through the location property of the window object and the second argument is the target URL which we will pass as _self because it makes the URL replace the current page.Closing this opened window using the javascript close method:Since we opened the new browser window using the javascript script therefore we can close it using the window.close() method. This method does not any argument and it closes the window on which it is called.JavaScript Program to Close a Browser Window Using window.close() MethodThe below program demonstrates the approach we discussed above.Output:Before clicking the close button browser window looks like the below.After clicking the close button, the above page closes.Explanation:First, we created an HTML document and under the body tag, we defined an h1 heading tag that displays Hello World!! and also we have defined a paragraph tag that says to click the button to close the window. Then we have defined the button and attached on click listener to it which defines what happens when the button is clicked.At last, we have the javascript script which defines the functionality of the above-defined function. The script contains a function in which we have defined a variable my_window and opened the new window, then we closed the current window using the close() method.ConclusionTo close a browser window we can use the javascript close method but we can use this method only when we have opened a new browser window using code.Due to modern security reasons, we cannot close a browser window that is opened by the user.To Open a new browser window we use the javascript open() method.To close this browser

SeleniumAutomation TestingTesting ToolsWe can open a browser window in incognito/private mode with Selenium webdriver in Python using the ChromeOptions class. We have to create an object of the ChromeOptions class.Then apply the method add_argument to that object and pass the parameter -- incognito has a parameter. Finally, this information has to be passed to the webdriver object.Syntaxc = webdriver.ChromeOptions()c.add_argument("--incognito")Example Live Demo-->from selenium import webdriver#object of ChromeOptions classc = webdriver.ChromeOptions()#incognito parameter passedc.add_argument("--incognito")#set chromodriver.exe pathdriver = webdriver.Chrome(executable_path="C:\chromedriver.exe",options=c)driver.implicitly_wait(0.5)#launch URLdriver.get(" Debomita Bhattacharjee Updated on: 03-Apr-2021 8K+ Views Related ArticlesHow to open a new window on a browser using Selenium WebDriver for python?How to open a browser window in full screen using Selenium WebDriver with C#?How to close child browser window in Selenium WebDriver using Java?How to maximize the browser window in Selenium WebDriver using C#?How to connect to an already open browser using Selenium Webdriver?How to open a link in new tab of chrome browser using Selenium WebDriver?How to Resize Browser Window in WebDriver?How to set window size using phantomjs and selenium webdriver in Python?How to open a new tab using Selenium WebDriver?How to hide Firefox window (Selenium WebDriver)?How to open a link in new tab using Selenium WebDriver?How to launch Edge browser with Selenium Webdriver?Capturing browser logs with Selenium WebDriver using Java.How does Incognito Mode work?How to Maximize window in chrome using webDriver (Python)?

Mock Browser OverviewA mock browser with window, document, location, navigation, local and session storage to use for client side code tests in a node environment. A majority of the implementation is from the jsdom project with enhancements for local and session storage plus some fixes for un-implemented document features (classList).The mock browser eliminates the need for a headless browser like phantomjs to provide a much faster unit test framework. It's perfect for browserify projects that run tests prior to compiling the bundle.Installation npm install mock-browser --saveIf you just use the mock for testing then '--save-dev' is more appropriate. But, the AbstractBrowser could (should) be used for run time to replace client logic that normally accesses globals provided by the local browser. This not only enhances testing and mocking but also enables cross-browser workarounds through interception rather than override.UseMock BrowserThe typical use case is a browserify project with unit tests that need to provide access to browser globals like window, document, location, etc. The best way to simulate this is to use a proxy wall between the normally global browser objects a require the application to get instances of window, document, etc. That way you can supply a mock for all of these objects with a common interface (AbstractBrowser). It looks like this... var MockBrowser = require('mock-browser').mocks.MockBrowser; var mock = new MockBrowser(); // and in the run-code inside some object var doc = mock.getDocument(), div = doc.createElement('div'); var storage = mock.getLocalStorage(); storage.setItem('mykey', 'my value'); assert storage.getItem('mykey') === 'my value';Mock Browser Object MethodsTwo convenience methods are added to make it easy to get either a window or DOM document mock.MockBrowser.createDocument()MockBrowser.createWindow()Abstract BrowserThe AbstractBrowser object can be used as an interface for run-time client apps to access browser window related objects. This approach enables code to be used both in and outside the browser. var AbstractBrowser = require('mock-browser').delegates.AbstractBrowser; // configure in some factory var opts = {}; if (typeof window === 'object') { // assign the browser window if it exists opts.window = window; } else { // create a mock window object for testing opts.window = MockBrowser.createWindow(); } // create the browser object with a real window in brwosers and mock when not in browser var browser = new AbstractBrowser( opts ); var doc = browser.getDocument(); var element = doc.getElementById('my-dom-element');Abstract Browser APIInstance methods...getDocument()getWindow()getLocation()getNavigator()getHistory()getLocalStorage()getSessionStorage()Object Methods...AbstractBrowser.extend(child, options) These methods are inherited by MockBrowser to provide a consistent interface between test and run-time environments.Extending AbstractBrowserFor run-time

Model Browser is displayed when at least one project is open. By default, Model Browser is placed at the left side of the main window. It is possible to move the Model Browser to any place on the MagicDraw window. Also, all tabs can be viewed separately and you can set up the Model Browser according to your needs by hiding the desired tabs. To change the size of either part of the Model BrowserDrag the bar that separates the two parts.To change the Model Browser positionUsing the Options menuFrom the Options menu, select Environment. The Environment Options dialog opens.Click on the Browser option group.In the Browser environment options pane, change the Browser Position property to Right or Left. Using Toggle In the upper-right corner of the selected tab in the Model Browser, click the Toggle auto-hide or Toggle floating button.This action changes the layout of the MagicDraw interface. To close or reopen the desired tab of the Model BrowserUsing the Window menu, choose the Model Browser tab you want to close or open. To reset all Model Browser tabs to the default positionFrom the Window menu, choose the Reset Windows Configuration command.To sort items in the Model Browser alphabeticallyFrom the Options menu, select Environment. The Environment Options dialog opens.Click the Browser option group.In the Browser options pane, set the Sort Alphabetically value to true (the default value is true).
