OnContextMenu Event

Use the oncontextmenu event list to disable the right-click menu

onconTextmenu==false; the right-click menu is disabled, and copying can be disabled using this.

 

Add attribute code to <body>:

οncοntextmenu="return false"              

onselectstart="return false"

οncοpy="return false"

 

Prevent users from saving web pages:

Using the <noscript><iframe src=*.html></iframe></noscript> tag can prevent the web page from being saved directly, but it cannot prevent the web page from being downloaded by people using tools.

* is a wildcard.

Example 1:

<html>
<head>
<title>OnContextMenu Event</title>

<script language="JavaScript">
<!--

function uFunction()

{    ='You pressed the right mouse button, but the right-click menu cannot be displayed! ';}

function uFunction2()

{    ='You have pressed Ctrl+right mouse button to display the right-click menu. ';}

//-->

</script>
</head>

<body οncοntextmenu="if(!){uFunction();return false}else{uFunction2()}">

<div > You pressed the right mouse button, but the right-click menu cannot be displayed! <br>You have pressed Ctrl+right mouse button to display the right-click menu.
</div></body>
</html>
