How to disable right-click code in html

HTML code implementation method for disabling mouse right-clicking

In Web development, the copyright protection of the page is a crucial part. In order to prevent others from copying, downloading or taking screenshots of web content, we can use some technical means to limit user behavior. Among them, disabling the right-click function is a simple and effective method. The following will introduce the code implementation method of disabling the right mouse click in HTML.

1. Using JavaScript code

In HTML documents, we can use JavaScript code to disable the right mouse button function. The specific implementation steps are as follows:

1. Add the following JavaScript code in the HTML document:

2. In the above code snippet, document.oncontextmenu is an event handling function, which will be triggered on the right click is called when. The return false statement will disable the default right-click menu from popping up, thus achieving the effect of disabling right-click.

2. Use HTML5 features

In HTML5, a new attribute is provided: oncontextmenu. This property can be used to disable right-click functionality. This method is simpler than JavaScript implementation. The specific implementation steps are as follows:

1. Add the following code in the HTML document:

2. In the above code snippet, the oncontextmenu attribute is used and its value is set to return false. This will disable the default behavior of the right mouse button.

It should be noted that this method is only applicable to HTML5 and above.

3. CSS to disable the right mouse button

In addition to the above two methods, we can also use CSS style sheets to disable the right mouse button. The specific implementation steps are as follows:

1. Add the following code in the style sheet file:

body {
-webkit-touch-callout: none; / iOS Safari /

-webkit-user-select: none; /* Chrome/Safari/Opera */
 -khtml-user-select: none; /* Konqueror */
   -moz-user-select: none; /* Firefox */
    -ms-user-select: none; /* Internet Explorer/Edge */
        user-select: none; /* Non-prefixed version, currently not supported by any browser */

}

2. The user-select attribute in the above code will prohibit the user from selecting text, thus indirectly achieving the purpose of disabling the right click.

It should be noted that this method not only disables the right-click function, but also disables the mouse selection function.

To sum up, we can use JavaScript, HTML5 and CSS to implement the function of disabling the right mouse button. According to different needs, different methods can be chosen for implementation. At the same time, you also need to pay attention to possible compatibility issues and usage restrictions to ensure the normal display and function implementation of the page.
