To cancel the right-click menu on the web page, we need to use JavaScript to achieve it.

The method is as follows:

Write a script file

Introduce a JavaScript file at the head of the HTML file, the code is as follows:

<script type="text/javascript">
//屏蔽网页右键菜单
document.oncontextmenu=new Function("event.returnValue=false;");
</script>

Copy after login

Run the script when the page loads

Add the onload attribute to the body tag of HTML to automatically run the script when the page loads.

<body onload="load()">
...
</body>

Copy after login

The JavaScript code is modified as follows:

<script type="text/javascript">
function load() {
  //屏蔽网页右键菜单
  document.oncontextmenu=new Function("event.returnValue=false;");
}
</script>
