How to close the current window in HTML?

In web development, closing the current window is a common operation. Whether after submitting a form or completing a series of processes, closing the current window can improve the user experience. So, how does HTML close the current window?

In HTML, you can use JavaScript's window.close() method to close the current window. This method works in any modern browser and does not require any additional plugins or extensions.

To use the window.close() method, you only need to add a line of code where you need to close the current window. For example, after submitting the form, you can use the following code to close the window after processing the form data:

window.close();

This method is simple and convenient, but it requires user authorization, otherwise it will be intercepted by the browser. Additionally, if you want to use this method on other websites, you need to be aware of browser security limitations. For security reasons, modern browsers generally do not allow closing a window that was not opened by a script. This means that opening a new window within a window and then trying to close the original window using the window.close() method will not work.

If you need to close a window opened by JavaScript other than the current window, you may want to add a default name to the window.open() method to do so if necessary. For example:

var myWindow = window.open("http://www.example.com", "exampleWindow");
// ...
myWindow.close();

In this example, the window.open() method will open a window named "exampleWindow", you can use myWindow# in subsequent code ## Variables refer to it. The final myWindow.close() method will close the window.

No matter which method you use, remember to emphasize when to close the window and complete all necessary operations and data submission before closing the window.

Summary

Close the current window is one of the very common operations in web development. In HTML, this can be easily accomplished using JavaScript's

window.close() method. However, there are some security restrictions that need to be noted. For example, this method must be used in a window opened through JavaScript. Additionally, all necessary operations and data submissions must be completed before closing the window.
