Preventing copy-paste all the rich text editor in SharePoint

As part of an accessible Web sites in SharePoint, this time I will present the code prevents the copy-paste.

The following code prevents copy-paste content editor rich text field

/*  ECM  */

function disablePasteForRTE() {

    Type.registerNamespace("RTE");

    if (RTE) {

        if (RTE.RichTextEditor != null) {

            RTE.RichTextEditor.paste = function () {

                RTE.Cursor.paste(true);

            }

            RTE.Cursor.$3C_0 = true;

        }

    }

}

if (_spBodyOnLoadFunctionNames != null) {

    _spBodyOnLoadFunctionNames.push('disablePasteForRTE');

}

/* End ECM *
