How to close the current window event in javascript

JavaScript is a scripting language commonly used to write front-end interactive effects on web pages. Its powerful operating performance is often widely used in web development. In many cases, we need to implement some special functions through JavaScript to enhance the user experience. Among them, closing the current window event is a frequently used function.

In JavaScript, there are two ways to close the current window event, which are triggered through links and through code. Below, we will introduce these two methods and their implementation in detail.

Method 1: Trigger the close current window event through a link

It is relatively simple to close the current window event through a link. You only need to use JavaScript code in the hyperlink. The sample code is as follows:

<a href="javascript:window.close();">关闭当前窗口</a>

Code explanation: Use the JavaScript code "window.close();" in the hyperlink to close the current window. "javascript:" indicates that this is a JavaScript code.

It should be noted that this method can only close the window opened by the window.open method. Windows opened using window.location.href cannot be closed using this method.

Method 2: Trigger the closing event of the current window through code

To trigger the closing event of the current window through code, you need to use the close method of the window object. Through this method, the effect of closing the current window can be achieved in JavaScript. The sample code is as follows:

window.close();

Code explanation: Use the close method of the window object to close the current window.

It should be noted that this method can only close the window where the current script is located. For new windows opened through JavaScript, you need to use this method in the window to close it.

In addition to calling the window.close method directly, you can also use the event mechanism to close the current window. For example, when a button is clicked, the onclick event can be used to trigger this method. The sample code is as follows:

<button onclick="window.close()">关闭当前窗口</button>

Code explanation: Call the window.close method in the button's onclick event to close the current window.

It should be noted that if the window.close method is used, the browser will pop up a prompt box to prompt the user whether to close the current window. This is a mandatory mechanism set up to avoid misoperation. Currently, there is no reliable way to disable this prompt box.

Summary

Close the current window event is a common operation in JavaScript, which can be easily achieved through the above two methods. It should be noted that due to browser security restrictions, closing may fail or a prompt box may pop up. Therefore, in actual development, it is necessary to choose the appropriate closing method according to specific needs, and try to avoid adverse consequences caused by misoperation as much as possible.
