案例二：
<html> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Zero Clipboard Test</title> </script> </head> <body> <script type="text/javascript"> function jsCopy(){ var e=document.getElementById("contents");//物件是contents e.select(); //選擇物件 tag=document.execCommand("Copy"); //執行瀏覽器複製命令 if(tag){ alert('複製內容成功'); } } </script> <textarea id="contents" cols="40" rows="5"></textarea> <br /> <input type="button" onClick="jsCopy();" value="複製" /> </body> </html>
以上都可以執行，親自測試！
