Disable ‘Inspect Element’ And ‘View Page Source’

Step 1 – Disabling Mouse Right Click On Website

    document.addEventListener('contextmenu', function(e){
    e.preventDefault();
    });

you can show an alert

 document.addEventListener('contextmenu', function(e){
alert("Sorry, right click is disabled to prevent leakage of confidential functions");
e.preventDefault();
});

Step 2 – Disabling Shortcut key combination that allows inspecting elements

There are few shortcuts available to use the ‘inspect element‘ or ‘view page-source‘ option. Such As:

• “Ctrl+Shift+I” for ‘Inspect Element‘
• “Ctrl+Shift+J” for ‘Inspect Element‘ Console panel
• “Ctrl+Shift+C” for ‘Inspect Element‘ Elements panel
• “Ctrl+S” for Saving Website as HTML file
• “Ctrl+U” for ‘View Source Code‘

code

document.onkeydown = function(e) {
  if(event.keyCode == 123) {
     return false;
  }
  if(e.ctrlKey && e.shiftKey && e.keyCode == 'I'.charCodeAt(0)) {
     return false;
  }
  if(e.ctrlKey && e.shiftKey && e.keyCode == 'C'.charCodeAt(0)) {
     return false;
  }
  if(e.ctrlKey && e.shiftKey && e.keyCode == 'J'.charCodeAt(0)) {
     return false;
  }
  if(e.ctrlKey && e.keyCode == 'U'.charCodeAt(0)) {
     return false;
  }
    if(e.ctrlKey && e.keyCode == 'S'.charCodeAt(0)) {
     return false;
  }

}
