How to disable Ctrl C/V using javascript for both internet explorer and firefox browsers
javascript
Solution
- I don't like when browsers do this to me, and
- It's easy to work around, and
- This doesn't count as "secure" by any definition, but
Use `element.on(?:``copy`|`cut`|`paste``)`
<body oncopy="return false" oncut="return false" onpaste="return false">
Problem
I am making this javascript code in order to disable Ctlr+c and Ctlr+v, prenscreen, ALT+TAB, Ctlr+S, and PrintScreen keys. ``` <html> <head> <script language="javascript"> function Disable_Control_C() { var keystroke = String.fromCharCode(event.keyCode).toLowerCase(); if (event.ctrlKey && (keystroke == 'c' || keystroke == 'v')) { alert("let's see"); event.returnValue = false; // disable Ctrl+C } } </script> </head> <body onkeydown="javascript:Disable_Control_C()"> Hello World! </body> </html> ``` unfortunately, code is working on IE browser, but not working on firefox. Can anyone here advice?
