Jquery-based implementation code for disabling right-click, Text Selection, and copy keys

Sometimes, for some reason, you need to disable the user's right-click, Text Selection Function, copy button, and other operations. You can refer to the following code for use in IE, firefox, and Google browsers at the same time, the filtered code is as follows:

The Code is as follows:

// Disable right-click, Text Selection, and copy button
$ (Document). bind ("contextmenu", function () {return false ;});
$ (Document). bind ("selectstart", function () {return false ;});
$ (Document). keydown (function () {return key (arguments [0])});

// A warning is prompted when you press the button.
Function key (e ){
Var keynum;
If (window. event ){
Keynum = e. keyCode; // IE
} Else if (e. which ){
Keynum = e. which; // Netscape/Firefox/Opera
}
If (keynum = 17 ){
Alert ("copying prohibited content !");
Return false;
}
}

// Disable right-click, Text Selection, and copy button
$ (Document). bind ("contextmenu", function () {return false ;});
$ (Document). bind ("selectstart", function () {return false ;});
$ (Document). keydown (function () {return key (arguments [0])});

// A warning is prompted when you press the button.
Function key (e ){
Var keynum;
If (window. event) // IE
{
Keynum = e. keyCode;
}
Else if (e. which) // Netscape/Firefox/Opera
{
Keynum = e. which;
}
If (keynum = 17) {alert ("copying prohibited content! "); Return false ;}
}
