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>
- 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>
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>
- Apply to PHP
In PHP files, you can also use the above method to cancel the right-click menu. Just put the above code in the head tag before the PHP code block.
<!DOCTYPE html>

<meta charset="utf-8">
