The method of automatically adding copyright information to the contents of the copying network

You can find many similar codes on the Internet , Join the web body Part of it .

For example, the following code ：

// Copy content and add copyright information automatically  
document.body.oncopy = function ()  
{ 
    setTimeout( 
        function () 
        { 
            var text = clipboardData.getData("text"); 
            if (text) 
            { 
                text = text + "\r\n Original text 【*****】, Reprint please keep the original link ："+location.href; 
                clipboardData.setData("text", text); 
            } 
        }, 
        100 
    ) 
}
