// Disable right-click menu, copy, and select $ (document). bind ("contextmenu copy selectstart", function () {return false ;});

Method 2:

// Disable Ctrl + C and Ctrl + V (supported by all browsers) $ (document ). keydown (function (e) {if (e. ctrlKey & (e. keyCode = 65 | e. keyCode = 67) {return false ;}});

Method 3:

// Set CSS to prohibit selection (this code is not required if the following CSS is written, supported by the new browser) $ (function () {$ ("body" ).css ({"-moz-user-select": "none", "-webkit-user-select": "none ", "-ms-user-select": "none", "-khtml-user-select": "none", "-o-user-select": "none ", "user-select": "none "});});
