Prohibit copying Web page content

Take a note.

Disable the right-click menu, Copy, select $ (document). Bind ("ContextMenu copy Selectstart", function () {    return false;}); /Disable CTRL + C and CTRL + V (all browsers support) $ (document). KeyDown (function (e) {    if (e.ctrlkey && (e.keycode = = | | | e.keycode = = ()) {        return false;    }}); /Set CSS Disable selection (if you write the following CSS you do not need this piece of code, the new browser support) $ (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 "    });

Prevents JavaScript from disabling, can be written in CSS (new browser support, and gradually become the standard):

body {    -moz-user-select:none;  /* Firefox Private properties */    -webkit-user-select:none;  /* WebKit Kernel private properties */    -ms-user-select:none;  /* IE private properties (IE10 and later) */    -khtml-user-select:none;  /* khtml Kernel private properties */    -o-user-select:none;  /* Opera Private properties */    User-select:none;  /* CSS3 Property */}
